There will never be space travel beyond our own tiny solar system.

A message to all the people. REMEMBER how you began. The first time is the only time you remember forever.

# 1 challenge, and one we will fail, existing as a species long enough to attain space travel knowledge.

Earth is the only spacecraft able to carry us through the universe. We are all travelers, we just don’t realize it

To sustain long-term human life in space will require artificial gravity, generated using the centrifugal force. To accomplish that, we will have to construct a giant rotating cylinder, probably at least 200 meters in diameter. It will have to be assembled in orbit, with the components sent up there one at a time. We will also need far better shielding from the intense radiation of interplanetary space. The crew will have to have at least some forms of entertainment and creature comforts (perhaps individual cabins), as well as "earthlike" food. That's a very tall order.

I want Neil to one day look at Star Citizen and talk about how it might compare to real life etc. Would be cool to see him talk about the biggest space nerd game out there.

I think I prefer living on Earth. Excellent video 🌍

We’ll figure it out, cause I need to travel to a different multiverse to meet myself and date my self.

How are we going to turn the craft to avoid hitting something when going really fast?

Nice to know the Geico Insurance Gecko is interested in space travel.

I've been watching space exploration videos for years. It's kinda discouraging to realize, our curiosity and ambitions has led to low orbit satellites. I can't wait to see Mars the way Arnold did in the movie Total Recall.

I love your channel ✨

2:05 Someone needs to explain what those little dots of light going past the spacecraft are.

Great stuff love this guy

8:14 mars earth timing is a bit the modern version of waiting for the right tides in historic times.

solar sail, i hope it works

Very intriguing video. I cannot believe that Dr. N. D. Tyson has not considered using a wire rope as a solenoid for a fuel-less propulsion means. Similar to the space elevator idea. Imagine a stationary wire rope, in space, several thousand miles long stretched tight between opposing rocket propelled depos on each end. The rockets only fire when needed. The depos collect solar energy and use a battery to energize the wire rope solenoid; or use nuclear energy. A magnetized yoke loop on the shuttle ship partially encircles the solenoid A desired acceleration speed is dialed in. Same thing in reverse for slowing down. Two solenoids near Mars. Two near Earth; and two in between Earth and Mars. One week there and one week back.

We've got mega-problems here on Earth to be addressed before any realistic consideration of inter-planetary travel.

I been wanting to ask you a question for a long time about the other planets. Specifically earth like planets. There are some out there apparently 30% or 60% bigger you can tell me more or less but the question is if lets say the planet is 30% and lets say human like species lives there would they be particularly 30% bigger? Like would we look like ants to them or dwarfs?

No matter where you live on earth, what color your skin is or what your religious beliefs are, we are all the same immortal, spiritual, cosmic beings of light, vibration and frequency, who love and cherish each other beyond scope and measure when we’re back home together. Most of you, except a very tiny percentage of the population, have forgotten who you really are and where you’re actually from and that we are from one collective source (the creator of all) of energy in the cosmos. Some believers will call this reality or realm ‘Heaven’ or ‘the other side’, but whatever name you do choose to call it, the bottom line, it’s been our true spiritual home since time immemorial. Don’t fear death, there’s nothing to be afraid of because you are going back home to your countless love ones you’ve made over eons of time and space. It’s all the same to me but some people find comfort with labels and there’s nothing wrong with that I suppose. I do believe though, the word ‘Heaven’ has gotten a bit misused over time, because to me it’s not a place you can go, but a feeling of belonging and acceptance and love beyond your wildest imaginations and dreams and desires for the one, known only as, ‘I AM’. Your consciousnesses and your soul are one in the same. Earth is not your real home. The place your consciousnesses goes when you pass away, is all the same thing and again it’s where our spiritual home really is. When you do cross over, It’s simply a matter of closing your eyes here and immediately reopening your eyes there, It happens instantaneously. Actually it happens so fast that most people that have NDE’s (near death experiences) say that at first they didn’t even realize they were dead for a while. Even the ones that died on the operating table in the hospital, for example, have said that as they were out of their bodies temporarily and floating up near the ceiling, they were wondering who was on the table below in the room because they just felt that there wasn’t any way that person could be them. Only when they don’t get a response from someone in the room or suddenly walk through a wall is when they realize something happened to them. You have all lived many, many lifetimes through reincarnation, quite possibly thousands of times, perhaps more. More than likely, you have been every race, gender, ethnicity, color, even every species throughout all the billions of galaxies and the cosmos and lived from every time period going all the way back to the very first inhabitants of every planet that contains life. Again, you are immortal and have died so many times throughout the spectrum of time. Every time your soul comes back to a new being, you and your soul guardian, or as some people like to call them, their guardian angels, will pick your life’s blueprint of what you’re going to do and accomplish. You’re not meant to remember this most times, but there will be some instances where the source creator will let you retain your memories from your full existence and you’ll get to remember them during your journey throughout that particular lifetime’s span, for reasons the source sees fit. If your memories are removed for a particular lifecycle, the creator wants you to discover this throughout that lifetime and on your own, learning lessons from it. If everyone was just told what they had to accomplish or learn every time, they wouldn’t be able to properly get what was needed out of each life. The core learning for each soul and every life time is the ability to love one another and show compassion for each other. For some beings this takes a bit longer and they may want or need to keep coming back until it’s accomplished. For most beings though, I’ve heard they want to finish the lessons and be done with it for good, stating that life on primitive planets such as Earth, is just to hard and they want it to be over with. I would have to agree with that sentiment, life is hard on Earth unless you were born into a family that has everything and everything is done for you and on top of that, you were blessed with wonderful looks or talents that leave you never wanting for anything at all. It’s a fairly low percentage rate of beings this happens to but we’ve probably all experienced a small amount of success in one of our lifetimes or another. Please stop the wars and fighting amongst each other and start to love one another, as it should be. We are spiritual beings having a physical experience, not physical beings having a spiritual experience. Jesus said on the cross: “Father, forgive them for they do not know what they are doing”. Maybe we will be able to do the same one day, forgive our enemies. I will get some comments sometimes saying, “some don’t deserve it”, but that will be between, them and the creator. If you want any other perspective or guidance on this information, watch the programs called: (The Ghost inside my Child), and NDE’s, (Near Death Experience) testimonials. Most of these are on KZfaq. There are many different channels on KZfaq with different hosts, so try if you can to eventually watch them all. No two experiences are ever the same and all have different information that others won’t have. The more you watch and learn, the better of an understanding you will have of everything I have mentioned in here. Please watch as many of these videos/episodes as you can, because you will get a broader, more detailed understanding of what it’s all about and what’s to come. I promise you, this will completely change your life for the better and you will never fear death again. Some of you have said, “it’s the fear of pain” that you associate with death that you fear mostly and I get that as well believe me. Nobody wants to die of a painful or agonizing illness or disease, especially something as terrible as cancer for example that can go on for years sometimes. It will also give you a complete sense of peace and perspective for all things in your life. You will become exponentially more compassionate towards people and even animals once you learn the truth about it all. You will learn to love yourself first and foremost and that in return, will help you learn to love others better as well. I completely understand if you can’t and/or won’t initially except some of what I’m telling you. But I do hope and pray that you will try to expand your mind from what you’ve been taught. Trying to get rid of what you were taught since birth and accept something completely new and what some have called, ‘fantastical’ isn’t the easiest thing to do, especially if you like the way things are in your life and don’t except change that easy. I myself have been accused by my family and friends for being what they have called ‘Pig Headed’. I’m not that way anymore, I have completely changed since learning the truth. I’ve had some ask me about the situation with babies or young children and cancer or illness, disease and ‘why god takes them at such a young age’. Saying, ‘how’s that fair, they didn’t do anything to deserve that’ or ‘why would they pick a life just to turn around and die’. I initially had issues with all that as well, but over time and learning, it became clear that sometimes the life blueprint that’s picked, is not always about you, but those you choose to be born unto. A mother or father may need to experience or learn humility or sacrifice and yes, sadly the suffering for the loss of a child. I know it sounds cruel but for whatever reason, it was ultimately necessary and the creators plan. We’re not meant to know or understand everything, that’s essentially in the creators hands. I was a nonbeliever and hardcore sceptic when I first heard about this information but the more knowledge one learns and acquires, the more you will realize it all to be true and not just a ‘nice story’, as one guy responded back to me recently. Please don’t ignore this, it has everything to do with why you’re here. Some things are true whether you believe them or not. I would like to say though, that I’m not in any way an expert on the subject or claim to know everything, not even close. I encourage you to do your own research and come to your own conclusions, have a blessed day or night.

Absolutely in the void 👍

When we land on Mars, I wonder if there's going to be greetors

Hardened Asteroid-Belters hauling the 9 month trip back and forth to keep the Fueling Stations between Earth & Mars filled are what is needed.

It is a projection of trajectory!

At one g, it would only take 42 hours to get to Mars, assuming it is in opposition. That includes the deceleration that starts midway. So not weeks. A constant g-drive would be incredible, if only we had an energy source to power it.

assuming we have been visited, and being visited , how did they get here? thats my first question if i ever meet one

1 year on earth doesnt mean 1 year on them. it could be 1 day or 1 week. our definition of time is only relative to us by how we measure 1 revolution of earth to our parent star. for us they travel for hundred of years, but for them, they only travel 1 year or so. depends on how they measure time. and maybe there is a region in space that light is travelling faster than by how we understood light speed limit besides super massive gravity can bend or distort light. who knows.

Until someone or a civilization can harness wormholes interstellar travel is impossible and could be the issue for actual contact with aliens….

We have a long way to go before we can travel to the stars. I would estimate 100 years before we get the technology? One big question which keeps nagging me since a took a interest with UFOs since the Roswell saga why haven’t we got a helping hand with are interstellar travellers? Is are governments holding back? Excellent video thanks for sharing your thoughts

If they must attempt this, the moon is the only logical place to “practice” on. I remain convinced there will never be profitable and practical examples to make this happen. If we could pull this kind of activity off, we would have well established “colonies” in all of the remote corners of this planet and the cost of living on destination islands would be no more expensive than living on any mainland. In short, the base economics of space travel will always be a zero sum depletion of earth resources.

Hello Sir Neil deGrasse Tyson, I have a question. was the moon landing true?

Imagine the look on everybody's face if they see a cat run by while they're in there enclosures on Mars

Please Mr. Tyson tryout 4 hosting jeparody PLEASE !!!!

Once we crack this, everything else will unfold

1:40 sorry. But ion engines defnetly a devlopement. All we need to do is scale it up.

So my question is why aren’t we focusing on making jet sized space ships instead of these huge things we can’t make go into space

The more this guy describes the ramifications and logistics of this space travel, you know it just doesn't seem like a good payoff, to actually try it. How about solving some of this planets issues.

Question : Why do we as humans are so drawn to look up at the Stars? I surmise that our origins may have come from distant stars beyond our solar system... All comments welcome.

Key and Peele brought me here.

Is it possible,🤔...to create a magnetosphere around Mars or any other planet, dwarf or planetesimal close to us?

Solar sail Spacecraft shipping cargo from where to where. Forgeting one thing distances in space are soooo HUGE that using solar sails is simple not feasible. There are so many problems. First technical. That kind of sail is very fragile and in completly empty space wil be sufficient, but only one alone mateorites, even small one will destroy that sail and that will be end. I dont see any cheance to repair it in empty space. When we will be leaving our solar system light pressure will diminish with distance and with expanding distance between sun and our specacraft just simply slows down and with no access to any close sun with sun wind, spacecraft simply slows down to speed of walking man and that will be just drifting pice of junk in imaginable space. This is like sailship drifting without wind. Another problem, it would take 5ousedns of years to reach any closest objects in space, especialy we dont know acctualy where to go, because we dont know which planets we can acctualy reach to be worth exploring. Tell me how we can decide where to go if we dont have neither technology or information to know which planet or plantes are worth yo explore. Additionaly, solars sails wont resolve problems with powering life supporting system inside spacecraft to actually allow us to survive. Another problem, people evolved to live like maximum 90 or 100 years, unless we find the way to make us imortal, I dont see how we can travel with that kind of slaw ship THOUSENDS years. We can eventualy send people just to reproduce during that trip, and in that case like next generation will reach that distant planet. Howevere we stumble with another problem, how we compress so much biomas enough to support whole crew or next generation. We can for example use hybernation technolgy to freez whole crew for undefined time but again how much energy we would need to provide if we dont really know for how long. To resolve these problems we need to discover new technology which we dont have right now. Only way to efficiently travel in these distances requires to discover some kind Warp drive, directly from StarTrek, otherwise that kind of travels are simply not possible and fact that we dont see any aliens visiting us or even detecting signals from aliens make me rather thinking that these aliens, optimisticaly assuming are more technologicaly advanced than us, didnt resolve problem with long distance travelling and not even long distance communication. I can safety assume that aliens in distant space are only simple bilogical organisms starting evolvin, aliens on level of development our middle ages or possible similar to our development of technology. No chance to communicate or long distant traval whats so ever. We evolve to life and flourish on midium size planet not really for long distant space exploration. Wormholes dosent provide anything. There is no wormhole in our vicinity. Maybe in theortical phisics are possible. But how we can generate them, how we can point them in our destination in distant space. There is no technology to produce or even utilise them. For me they are more possible to discover some kind magical worp drive rather than generate and utilise wormholes. Video focused rather on small problems like our body reaction for lack of 1G garvity instead answering question if we are on the way to technologicaly resolve problems with long distance travel. In some of sf movie I can find more contents than it tha movie. As much as like Neil Tyson, he didnt say anything revolting and interesting, and movie was simply boring with some nice animation. Till we solve problem with our short span life and design some kind magic worp drive we are stuck here possible to the end of our civilisation.

They better figure it out because if not, Mankind goes Extinct.

Come on, Neil...are you unironically saying that time dilation makes space travel less interesting? I'd kill to time travel + space travel at once, I hope I come back here and 150 years have passed - hope the future will have far better things than today.

The space craft does not have to move to move

Fusion 15 minutes to Mars

I am destined to explore. I have such a strong desire. Hopefully humanity as well! With love, Jacob Sevall.

Traveling in outer space is a problemo Bec of time

The shuttle is a taxi and that's it. We aren't going anywhere for real yet and even that takes too long

Even if we lived for million years who would wanna travel for a million years... he said it's ok if we lived for million years....

Any speed any distance one jump my space craft

Build the rocket in space?

At 10% of the speed of light, for every year on the spacecraft, 366.84 days would have passed on Earth. At 20% - 373.53 days or one year and 8.53 days At 40% - 398.25 days or one year and 33.25 days At 60% - 456.25 days or one year and 91.25 days At 80% - 608.34 days or one year and 243.34 days At 90% -- 837.37 days or two years and 107.37 days At 95% -1168.93 days or three years and 73.94 days At 99% - 2587.42 days or seven years and 133 days At 99.90% - 8163.69 days or 22 years and 131 days At 99.99% -25810.00 days or 70 years and 259 days At 99.999% - 81616.66 days or 223 years and 219 days

I see human beings going to outer space in 200 or 250 years time, in that time we'll be mostly map out exploring colonizing the solar system.

Also why can’t we ride the atmosphere out off earth??

We can send very small Sail ships powered by lasers to Andromeda now!

If all the countries came together into a united space program then we'd be back on the moon colonizing it, & that would lead to tech innovations

If you understand science fact, rather than science fantasy, then you understand that vehicles of extraterrestrial origin have never visited the Earth. The distances to other star systems are too far and thus too expensive in terms of time, energy, and cost to develop and then deploy extraterrestrial vehicles. There is no such thing as faster than light speed travel; physically impossible; always has been, always will be. Ignore all wand waving and focus only what we know that is demonstrable under the known laws of physics.

💖💖💕

I considered space travel

Good video, but there is literally nothing about Mars that makes it ideal for human colonization. Consider that even the majority of Earth is not colonized by humans, and even the least hospitable place here would be a piece of cake to colonize compared to any place on Mars. Now l am not saying humans will never visit Mars. But visiting and colonizing are different things. To colonize Mars would require advances in technology and many fields of science and human development on a scale of multiple orders of magnitude. And even if we could, anyone living there would face a life that very few could stand.

I want to hear this stuff from literal rocket scientists not an astrophysicist

For us to be able to access wormholes humanity must abolish various things like third world starvation, factory farming, greed, God won't allow a species that depends on factory farms to multiple thereby creating even more factory farms

Does that mean A spacecraft close to the sun can see the past of the earth 8minute ago?

I think it is important to cut the myth of exploring down to size - it is greed or necessity that has driven all explorations, not 'because it is there'. It is very difficult to see Earth becoming richer by spending trillions on interstellar expeditions, rather than improving the lot of the billions on THIS planet. And remember, OVER-population is not going to be our problem in the future, UNDER-population is what we need to fix in the coming centuries. We know that distant star systems do not have 'exotic elements' that haven't been discovered, so WHY we would expand outside the Solar System, or even outside Earth (other than robot probes for scientific purposes), still is a 'solution looking for a problem'.

Unfortunately I agree.

Could we catch a ride on a comet?

nah no thanks I'll just wait for the Homestead company to build the Avalon cause I only travel in style😎

We better get this idea of traveling to another Earth or terraforming Mars out of our heads. It isn't happening for hundreds or even thousands of years. In the mean time Earth needs our total focus and efforts to keep it habitable and we're doing an absolutely shit job of that.

I don't believe you could tack in space with a solar sail

It will probably never be worth the time, effort, difficulty and lack of quality of life, nor be profitable travelling to the stars, as least for humans.

how about try and save the one and only home we will ever have the one called earth.

Klingons from the black hole spotted near Uranus Star Trek symbol on Mars 😂🤣😭 Where ya going ,but on screens .

You know time dilation is flase

We need electric space craft. Let's ask ELON and Toyota to get it done. Who knows, Toyota might spit out a whole ocean of water as an after burnner !!

We will may need to leave earth at some point....

Space ships with fans makes me laugh ,

Apply yourself to a multi-faceted existence, learn and connect to the multiverse the influence is quite powerful, profound, dominant and represents good, light and love, your psyche is key’- Andrew Rogers. The multiverse is a group of multiple universes. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, sentient beings, spirits, spirit guides, gods, goddess and aliens, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "other universes", "alternate universes", or "many worlds".

If I'm gonna go to Mars I sure as hell not coming back. How stupid would that be?

How do you buy artificial intelligence to make pharmaceuticals?

Why are you in a rush for interstellar space travel, our species is not ready yet, we would only get in trouble. I think in a millenia or two we will have become more enlighten then we will be ready!

Unless there's a worm hole it safe to say interstellar travel slim to none so how about all these "space geeks" turn the eyes to this plane let's clean up this planet before we go to Alpha centauri or wherever

Mars is NOT a good place to setup a long term base. Humans will degrade very fast on Mars. You also can't make a single mistake, you're dead!

We're not going anywhere.

The desire to exploit pilfer

A.G.I Will be man's last invention

Hard to take a guy serious who actually wrote an article on how Santa Claus is a racist

I wonder how people would open multiverse portals

#Wormholes #PhilosophyOfTimeTravel #3767

I believe we should stay here forever because drinking recycled urine is yucky. :p

We will destroy ourselves before we ever leave this planet. 😆

Why bother to take all that time in R+R to develop the need to inhabit another planet because we messed up this planet earth.All that time money and human lives lost in the name of escapism...or to go boldly where no man has gone before...etc.

We haven't even colonize our Beloved moon. Blah

The future may be cool but lame

Is he a serious skeptic or a celebrity disinformation scientist?

This guy could travel through space just by his inflated ego.

Wouldn't it be great if we let NDT talk about real science instead of all this fanboy SyFy stuff?

If Neil deGrasse Tyson is pushing space travel like he pushed the game, "Space Odyssey - The Video Game" count on never getting there. Just another rip-off from the physicist.

He is speaking on a High school level and it is worthless and insults me!

Complete waste of time.
