The suggestion that you could get to any part of the universe in one lifetime ignores the fact that space itself is expanding, in some areas faster than the speed of light

As an object moves faster, its inertial mass increases and therefore as it gets faster, a greater amount of energy is needed for each additional 1m/s increase in speed. There isn’t enough energy in the Universe to get even a single electron to the speed of light.

I thought this was great how I wish my oldl days at school explained things in such a practical way.....

Star trek invented warp engines to brake theoretical light-speed limit by bending space. To bend space you need huge mass, for example like a planet mass.

In Star Trek they where not traveling using conventional means. The warp drive created a warp bubble that bypassed the space / time problem. However this is not been proven possible and would also require a massive amount of energy. Like the building blocks of the universe kind of energy.

3:50 faster than light wouldn't be going back in time tho? Wouldn't you just SEE things in reverse? Doesn't mean they're going back in time it just appears to be to our perspective

I would like to hear more about the shadow puppet and how it goes faster than light. I am not convinced this is true, think about it in a slower setting, like if you are watering the moon with a giant watering can and put fingers under the stream to make water “shadow” puppets, the drops will not fall where your hand is, moving it around will let drops fall, but these drops would have to travel from the giant can to the surface - taking time. Now think of the water drops as being darkness in the shadow puppet example, how can darkness travel faster than light?

“Nothing moves faster than light” Quantum Entanglement enters the chat

Why's everyone swaying like they're pissed

So that's why I can't hit the bed before the light goes out

what about the gravitational pull of a supermassive black hole?

the shadow over the moon thing is wrong. the change in theleading and trailing edge position of the shadow propogates to the moon at the speed of light

I kinda regret wondering about this, I’ll just accept you can’t because it’s complicated….

The moon shadow puppets idea broke my brain.

Technically moving at the speed of light is one aspect. We have bending time and space to decrease distance. We have matter transportation which is another.

They are just making claims without substantiating any real science. This video is about 40% accurate, basically the buzz feed of physics

these are reasons, but the basic reason is that every object is in constant motion in space-time at a single constant speed which is the speed of light. all motion you perceive in 3d space is relative motion and pretty much imaginary

So what if you could cancel out mass? If a flashlight had zero mass, and you turned it on and let it go. It would fly off at the speed of light. Being propelled by the photons.

In Star Trek they had solved the time problem, the same amount of time passed on the ship as on planets no matter the speed

when you travel faster than light the object becomes invisible as the object stop reflecting light at that speed. the so called equal to sonic boom would be a light trail that just stops as the object become invisible.

I wonder if Isaac Asimov’s jump ships would’ve any more possible than warp drive

That kind of irrelevant because the higgs field won't allow it. Everything is moving at the speed of light the higgs field gives everything mass slowing things down, if you go faster then light you would lose mass and fly apart. The closer you get to the speed of light the closer you become to breaking the effects of the higgs field holding your molecular structure together, the higgs field has to work twice as hard to slow you down requiring infinite energy thefore you would disintegrate. The only way you can go faster then light is if space is moving faster then light.

Well then this is the real reason why we have not been visited by aliens 🤣

Pure conjecture...thx for sharing ✌

Can we still go the same speed as light

Where does space get the energy to expand faster than light?

What I hear is that object that will not move is the planet you can't see in your path.

What about progressively reducing our mass as we approach speed of light?

I think its possible if they use negative energy.

It does not exist. You are confused. Electro magnetic levitation exists. With electromagnetic levitation one can speed a ship, or anything else, over obstacles at what might appear to be something nearly instantaneous, so called ‘light speeds’.

Dude, seriously, why do you want to? There’s no where else to go, and if humans are any indication of how brutal existence is, you’re not going to survive any “alien” encounter.

1000 years ago Iron can't fly

The universe expands faster then light!

you need a fusion reactor to get infinit energy

we can, outside space-time.

I think this sounds like the guy from Khans academy. Isnt he?

but if you had a bow that spreads thousands of light years from one side to the other....and a super massive human to use it....wouldn't the arrow go as fast as light maybe even faster????

Is this the guy from gameranx

then how does the flash do it

Before we broke past the speed of sound, scientists said you couldn’t and you’d hit a wall of air. Is this not history repeating itself?

I thought this was cool. I liked the voices.

What if you made light tangible and rode it ?

It's disapointting that bbc release this kind of video like they know it all and got whole got universe figured out. I think 1000 years ago if you tell me human are going to explore the mars and moon they will say the same thing it's impossible.

SIMPLE SCIENCE ANY ACTION REQUIRES A MOVEMENT THAT INCLUDES SLOWING DOWN

What about if you became the light?

If we could reach the speed of light, we would not be travelling at 300k km per second from our point of view. We would be travelling at INFINITE speed, from our point of view.

Wow, we’re obviously stuck in time. Well, maybe not really STUCK, but surely in the time equivalent of molasses.

Saying what we cannot do in science is the opposite of a explorative scientific mind. Saying we cannot go faster then light right now in this time is true, but saying it is impossible is closed minded. Who are you to say what we can and cannot do in thousand or a million years.

WHAT DO YOU MEAN WE TRAVEL THE SPEED OF LIGHT

Would this mean that people that exercise LITERALLY have more time???

"You did it! You bastards!" Charlton Heston in the iconic scene with the statue of liberty ruins on the beach.

Totally wrong. The reason why you can't go faster than light is very simple i.e. the speed of light in vacuo or "c" (~670,000,000 mph) is the speed at which the universe is refreshed, linearized.

If I were a scientist, I would rather get out of the community that aimed to achieve the speed of light, and tell them until now we were are pretty much did not understand 80% our body, and don't focus on achieving it because it will diminish our potential to discover a new possible way. If we can move a space craft from earth to pluto(the sad disowned planet to a piece of debris claimed by human) by just 1 month, that already a feat of engineering. I just wonder if every nation that invest in space industry or pioneer it just use billion to argue at each other.

I'm pretty sure back then they thought sea and air travel were impossible until they achieved it. It's possible, we just don't know how yet.

Prince Andrew's reputation travels faster than light.

If there is no friction in space and its almost a total vacuum then if you give any spaceship an initial velocity then it should maintain that velocity without any additional thrust. Then the fuel tank is only used for acceleration which should make it possible to travel at the speed of light.

I wouldn't say never. There's theories that unknown subatomic particles from dark matter could have physical attributes to make something of the sort possible. Only 5% of 'ordinary/normal' matter exists, the rest is mostly dark matter and dark energy, which we barely understand the laws of physics behind.

Wow Star Trek really got it wrong.

If something travelling faster than the speed of light needs an infinite amount of energy to slow it down, but produces massive levels of nuclear radiation, then you could harness that energy to take something up to the speed of light, as you would have an infinite nuclear power source. So give me a few minutes whilst I build a tachyon displacement device that will in turn create multiple supernovas in a controlled graviton chamber to produce the energy required to power my warp core propulsion system that will in turn help me reach the speed of light. I just need someone to build the space ship for me, I’m no good with a welder.

We know. ❤. Jacobs Ladder. Is. ❤. Belt. ❤. Plankton. ❤.

No! We cannot go faster than light because we cannot see where we’re going once we are beyond light 💡

Lowest mass object in the universe

What's Sonic Boom? Is it what I see Superman do in Man of Steel and BVS?!

Based on the information provided here, it appears to me that Anti-Gravitons could be used to decrease Mass to zero. At that point, very little Energy would be needed to reach the the Speed of Light, and even go faster than the Speed of Light.

The more you dig in, The more you get lost in uncertainty

I agre :)

Oh brother... Infinite energy still has to work over the course of time. At the speed of light all time is stopped so if you understand the formula for velocity and T equals 0. You begin to see the problem.

why can light reach that speed if it needs infinite energy?

They didn't really explain why you can't. I would like them to explain the math. How do you get the "infinite energy" result.

We cant travel faster than light because our universe is already expanding faster than light.Imagine a train traveling 100 km per hour and you are running behind the train at 100 km per hour you will never catch the train.

Yet...

You forgot to add the property of consciousness. All scientists know that if YOU are travelling close to the speed of light, for "you" (consciousness) time appears normal and doesn't slow down, your mass is still the same, and you do seem to shrink in size (relative to the direction you are travelling) . BONUS: if you turn your headlights on, light will travel at light speed away from you. BONUS#2: we do not know our true speed in the universe, because everything is moving, how fast, we'll never know.

No

I don't know why you said that if you could go close to the speed of light say .99c then you could go anywhere in the universe in one humans lifetime. I understand the time dilation, but that doesn't account for the fact that the observable universe is 10's of billions of light years across. Even if you approached light speed, even .99c, you still would only be able to travel to places that are within a humans lifetime in relation to their light year distance from you. Not to mention the fact that you would Never be able to go beyond our own local group because anything past that is being pushed away from us by dark energy faster than the speed of light. So that statement was highly inaccurate.

I think : Mechanics( quantum) of light : The light is the limit(the border,of things,the edge of the matter) Over the limit are no more things,( there is no matter anymore ) If you want to pass( break) the limit, you should use : not matter anymore, ( not particles anymore) (Light speed ) It can't be reached with mechanical movement( mechanical particles movement). Mechanical movement( motion) is for things under the light's limit,( things with mass, volume etc... For matter,)light is the "wall"( limit) between matter and " No matter " . Don't waste time to break the light's limit with particles ( like neutrino, tachyon etc..) In this state( situation) you don't have to do with particles , because you want to go over( beyond ) the light ( over the particles) therefore is wasting of time . Another parallel thought : The possible outcome : C= constant means : The light doesn't move,( doesn't travel ) The photons doesn't move, therefore ( speed of) light is constant, because they don't move , is just as to turn the page, light just display it( unveils it) , but doesn't move ( doesn't travel) The book 91:3 This is a new point of view So you should make another math system, another physical system ( over{ beyond} the matter) , should find new sources . If you will approach to the limit( to the border), the limit doesn't have sense anymore, if you pass the limit, the things will change, the system doesn't work anymore, a new system will be applied( will be working) , for example : if you want to become smaller and smaller and smaller , until you become a string, that is the edge, there is nothing beyond it, if you want to go beyond it, you should leave the entire system, and take a new( different) system . It is like to travel with a car, you can travel with the car until in front of you there is the sea, now you should leave the car and take a new vehicle ( a ship) , because the car doesn't work beyond the edge ( beyond the limit ,the land ), there is different environment beyond the land, the car doesn't work there, same is your system, you want to go there but your system doesn't work there, need a new system, new variables, "new tools "... 🦩

Get to the answer nt your childhood

Thanks for a nice video and educative view on how we percieve things nowadays. However, I don't believe: 1) Newton / Mayer / Einstein were right within more than the confines of your known universe (whatever that is...). 2) In impossible. Because in this case it means "by means known so far" e.g. propulsion. Think about doing weird sci-fi things like warping, teleportation, other dimension entering etc. 3) In being limited to thinking about speed. Some modern theories suggest that time and space folding is possible, that the teleportation is possible (I think this one has been actually even proved), and so on. So, for example, think about getting to a place not being faster than the speed of light, but using means that would make you appear at that place quicker than it would take you to get there by travelling the speed of light. No-travelling travelling. Hehe. And listen to this also: There can be (logically-wise) no beginning of "things" nor any true "ending" of space. Just try to ask "what was before, and before that, and before that that... or what is beyond the universe, and beyond that, and beyond that that, and...." you will easily come to understand that conclusion. Therefore the universum (not just "our" universe mind you, but the whole-whole of existence) is infinite and also has never begun in the true meaning of the word! It also arguably suggests that something came out of nothing. Thus, things like laws of energy conservation, enthropy etc are simply not valid in the broader sense of things (much much broader though :D ) These are maybe just some kind of engrafting into our local universe, or who knows. One day we will breach these enigmas, and what is deemed impossible today will be normal in the future. As it always has been in science after all.

"If you could send signals going faster than the speed of light, then you could send information back in time." That seems like a jump in logic. I don't see how one follows from the other.

bet there would've been a video just like this before we broke the speed of sound :)

👽

Ya but since space can you just warp the space itself. Honestly I'd say quantum entanglement for instant communication is more difficult.

But Star Trek uses a warp drive! That bends space, and there's no limits on how fast space itself can move. Granted, even though it is mathematically possible, it may be way too impractical to do. We'll see what Sonny White at Eagleworks comes up with; I'm keeping my fingers crossed.

Space is going FTLS …🎉 …🏴󠁧󠁢󠁳󠁣󠁴󠁿😎

Light can travel the speed of light because it;smass doesn't expand. Solve that, another substance that mass doesn't expand you should be able to go as fast as Speed of Light. That should be main point and most significant past of Star Trek not most criticized. Amazing how Roddenberry got so much right and continues to...holodeck.

WHY LIGHT??? Will someone answer that? How did we decide that 3*10^8m/s is it, and can't be exceeded? I've seen tons of videos and read thousands of blogs, but noone answers that... help!!!!

All I have to do is become light

Don't bump into anything either cap'n

Fun fact : actually time travels faster than light.. light got second rank. Lol

Enterprise with exhaust plumes?? Really??? And you want to explain FTL travel??

its this mindset of saying impossible to something is why we cannot go faster than light

it means light itself is still a baby because goes thru time dilation

too much giggling by a couple of amateurs.......

This is why i bought a 120hz screen:

Yes, we can.

Yes, yes we can. Just depends how you measure the "speed of light". Light moves at different speeds through different mediums.

Remember, people once thought that the earth was the center of our solar system. It is the same with lightspeed, in the far future humans will laugh at videos like this.

I am so disappointed in this, mostly because of how wrong they get stuff. If it was just a commentary on relativity and the speed of light it would be really educational. But it's not. It decided to bring star trek into things, and that's where things go badly sideways. Ships in the Star Trek universe don't actually go faster than the speed of light. They use warp drives. A warp drive does not currently exist, but the science behind it is (theoretically) sound. A warp drive allows you to EFFECTIVELY travel FTL (faster than light) without ACTUALLY travelling FTL. It does this by "punching a hole" through space-time and travelling through the "hole". Imagine the universe as a balloon. Now, identify two points on opposite sides of the balloon. Warp the balloon (squeeze it) until the two points are as close together as you can get them. Now imagine travelling from the one point to the other. Looking at the surface of the balloon, you will appear to have travelled the (long) distance from one side to the other, when in reality you travelled the much smaller distance between the two points you warped together. If the balloon was large enough, you will have travelled a distance so large in a time so small that your average speed will appear to be faster than the speed of light, but in reality you only travelled the much smaller warped distance at sublight speeds. Another area where this video gets things wrong is talking about sending signals or messages FTL. Lets forget, for a second, Star Trek using warp relay stations to accomplish this, because there is something even better - Quantum entanglement. We know that quantum entanglement exists, and very simply (VERY simply) what it does is create two particles that are 'linked' to each other in such a way that one particle mirrors the other - what happens to one particle happens to the other, even when they are separated by vast distances (as I said, this is VERY simplified, but it worjs to illustrate a point). Theoretically, if you have a quantum entangled pair, you can send messages (signals) across the pair by finding a way to encode information into the movement of the pair. This does not yet exist, and is purely theoretical, but the science behind it is well understood and pretty sound (for a theory).

The woman interviewer is just like "Uh-huh. Cut to the chase." She seemed so uninterested.

If it’s impossible to go the speed of light, why can light go the speed off light. And light is Instantly that speed. How does that work

Hahahahhhahahhahahaha
