Any sufficiently advanced technology would be undetectable to us or appear like magic. Imagine explaining what Wi-Fi is to a caveman...

What advanced civilization would want to make contact with us, when we can’t even get along with one another

we went from horseback to rocketships in less than 200 years, imagine a civilization that developed for a billion years

When human are clueless about a subject matter, we become very philosophical.

This assumes human behavior on creatures very different than us.

Life could be common, but intelligent life could be quite rare.

The universe is so old, many civilisation may have existed at one point. Probably very rare to have a civilisation that advanced thru millions of years. They probably die out before another civilisation pops up.

A civilization 50,000 years ahead of us could choose to remain completely invisible to us. Currently we could fly drones over aboriginal peoples and monitor them day and night without them having the slightest idea. Same concept.

Might be in a different plane of existence that we don't understand

We are the only species that tries to put time in a box

The scary thing is that there might be something civilizations like that are hiding from

We have only seen so little of the galaxy. It’s like looking at a cup of water from the ocean and saying there is no fish in the ocean

I don't think it's a question of if there is life out there but it's more about when. Not all life happens now just because we are here.

The universe is teeming with life, we just can’t tell because of the vast distances between us and them.

Imagine how advanced we would be if humans weren't so damn greedy.

They've all died of space dysentery trying to make it across the space equivalent of the Oregon trail

If we are talking about a very advanced civilization, why would they bother to "write themselves across the sky?"

It’s distance. Any alien civilisation would have to have a propulsion system faster than the speed of light to cover the vast distances between civilisations. They may not even be carbon based lifeforms.

If civilizations have been around for that one, I would assume ditching the physical form would be a logical go, because that is such a limiting factor on us. I think the problem is we tend to imagine what we would do instead of imagining where we would be because as technology goes on we’re constantly looking for faster and more convenient and eventually you’ll hit the road block of the human physical form becoming the bottleneck. and addressing that would be the logical next step to somehow separate consciousness from the physical form. So it is no longer limited by that.

As Eddy Griffin once said: “We are known throughout the Universe as the fckd up planet. Who would want to stop here?”

As if our civilization isn’t going to destroy itself or the planet in another 100 years or so. Time alone doesn’t lead to advancement

There's a reason time has mentioned Orion, Pleiades and Draco and Lyra.

The only shortfall in this story is - We can never imagine that such beings and their civilisations be like. The max we can go is what movies show us, and that won't be even scratching the surface !!

Imagine if we're actually the most advanced civilization in the Universe and if we are the ones who will travel to other planets within the next 200-300 years from now, and the aliens we're going to visit will look at us as we're imagining the advanced alien civilisation right now 🤔

Ai & cybors can live thousands of years while traveling between stars not needing air food water or warm temperatures

“IF” they survived. That’s the keyword. I feel like things are designed in a way that no one can stick around long enough to figure out everything

I love this stuff .So full of everything but accuracy.

Ants do not comprehend the presence of gods, they simply see stuff happening and assign some dumb meaning to them

Life is common! But it constantly getting wiped out .

One of many ideas that make no sense is that aliens would do anything like we do. They may be so far ahead of us we couldn't even imagine what is in their thought process.

The best evidence that intelligent life is out there is that theyre smart enough to acoid contacting us.

I can see his smile

We need to look for not just an earth like planet for life, but one with a single moon similar to ours for stable seasons.

The Fermi Paradox is the W. C. Field's version of "Go Away Son... you bother me"

Makes me want to listen to the great song in the year 2525, listen to it if you’ve never heard it before, says it all baby!

Who knows Brian? I think we are all living on guesstimates … and everyone has their reasons for why they have a best guess …

If we are a proof of civilisation of one 💫 star, surely with billion stars at least a few lakh civilisations are out there

Yea, the Greys are everywhere .

When they come here over and over like so many of us have seen And they see how kind we treat each other , you know like how we never fight wars against each other and how we share all our food with the entire planet,yeah it's strange how they haven't stopped here seeing how friendly and rational we are?!

it's completely naive to even think we are the only civilization that has ever existed in the 13.6B years of the universe

if civilizations are common, what is the likelihood that they can arise in the 1st 5 Billion years? or the 1st 10 Billion years of a planet's existence? We came along rather late in Earth's existence didn't we?

Whoever is out there, I think they went through pretty much similar crap that we go through but they did it millions of years ago

Some aliens visit earth regularly: some even pick up our plants but they mean no harm. We should watch out for the baddies though for soon there could be confrontation

Not having a baseline to measure from, we may be one of the earliest civilizations AND utterly alone.

They wrote there information and presence in something they knew would be around longer than the sky's. " our D.NA."

Let’s hope they don’t visit us like the Europeans visited the rest of the world

When civilizations become advanced enough to send out radio transmissions, it is also advanced enough to develop nuclear weapons and eliminates itself.

Earth is like the Alabama of the universe They would only visit for comic relief 😮‍💨

Consider if we're the only sapient species to ever arise in the universe. 🤯

Our civilization must be further along than A LOT of other civilizations as well. Not just the other way around every time!

Couldnt agree more. The likelihood of a cataclysmic event on any planet during its course in the universe is much higher than the likelihood that one species remains in place for millions of years.

If civilizations are rare, a surviving one is far rarer!

They did, Brian, they did. And still are. You just don't have eyes to see.

I kinda feel like writing their presence across the sky is the last thing they would do.

The scariest thought (except of "we're the only ones") is "we are the first". We are Forfathers/Ancients/Progenitors.

Love the metaphor "written their presence".

If they survived, important words

"Thanks for the fish!" 😂 🐬

the trouble with speculations like this is that it completely ignores the possibility that civilisations may devolve more often than they advance.

It's one thing to have a planet. It's another thing to have a planet with mine-able metals.

Why do we always assume other civilizations always want to zip around the universe? We think if WE want to, every civilization ever wants to.

This man never heard of the Prime Directive.

Why hasn’t anyone made a MOVIE with this concept in mind!? Instead of futuristic, historical! Can you imagine? 🥰

Maybe they are the intergalactic version of David Attenborough, watching with intrigue, delight and horror but not getting involved or letting their presents be felt.

I believe that this is exactly why, when you go to space, it's quiet. The universe knows what it's doing and going against that never goes well.

They did! They wiped out the dinosaurs and created their new experiment... mammals 😂

Look how far we’ve gone in the last 10 and 100 years.

There are limits to the universe and the speed at which you can travel is one of them. There is the very real possibility that the space between solar systems and galaxies are just too great to be able to easily navigate between them in any realistic time frames.

All of the alien civilizations live right here on earth.

Because this world is so dynamic

Meanwhile here we are on earth riding a spaceship created by the ancients

You can almost hear the “UFO’s are among us” group stomping their feet watching this and saying “no no no!!!! I’ve believed it all my Mr. phd! Your not ruining my fantasy with your facts!”. The rattling noise afterward are the sound of the foil from the hats

Indeed there are civilizations ahead of us!

After 13 billion years, there should be aliens everywhere. 👽

Just a quick mathematical thought of chance. Scientists say the chances of life happening on earth was 1 to 60 bilion. The milky way has 100 bilion stars, so that means there is a chance of 1.66 solar systens with life in the galaxy inclouding ours, if we say there is one habitable planet per solar system.

The real problem is that civilizations are separated by too great of distances to ever make contact with one another. The universe is constantly expanding as well, so good luck with that!

The problem is the speed at which technology exponentially evolves, one minute you are a species discovering science and in a few thousand years you're already evolved to exist in a state of energy in the 8th dimension

If predetermination exist then it's probably us from the future doing time travel

Life on earth evolved through a series of almost unbelievably random events. There are so many galaxies and so much time has elapsed but the chances of there being another advanced civilisation still seems to be 2 trillion galaxies to one.

I wonder if you could use the clockwork radio principle to power a probe that won’t be needed to be activated for decades, or possibly even longer. Like a probe sent to Alpha Centauri perhaps, with Solar Radiometers on the probe to both activate the probe as it nears the Solar system its aimed towards, and recharge the clockwork mechanism like a giant self rewinding watch that never stops running. The electronics would have to be powered like a clockwork radio, negating the need for batteries or Nuclear power, which will degrade over extremely long periods. This is the issue with the voyager probes as they age, despite the fact that the electronics and computers within the probe are functioning perfectly after nearly half a century of constant use. The probe would have to be large and capable of making independent decisions, which may require a large amount of older hardier computer chips. You could even go a step further, and have small landers on the larger probe that could be fired and directed towards other planets. They could be hardy probes, with a self contained non rechargeable clockwork power source of their own. Preferably a hardy probe to gather planetary data quickly, similar to the Venetian and Titan probes of the past. The only issue would be having a secondary rechargeable clockwork mechanism to power the transmitter, which would have to be very powerful for the extremely long distances to earth. Storage of information until broadcast would be vital. If Spacex can reduce the cost of launches further, perhaps we could have a mother ship probe that could launch smaller satellites like a Clockwork Cassinis, to examine planetary systems and their moons, as well as launch the aforementioned smaller probes This is a bit long winded and hypothetical but its worth thinking about.

the universe is still young… we are the first intelligent life

The important part is: "If they survived.."

There's only 2 possible explanations: - Other civilizations are so advanced that they made themselves invisible - It's not possible to overcome the pjysical limitations of space travel. Therefore, no civilization ever made it out their origin star system. Not sure which one is more terrifying...

Imagine still believing that CGI is real in 2023 🤔

bruh we got shit in the sky we don't know what it is lmao

Our biggest mistake is that we are attributing human standards on the unknown. We may just find out that our understanding of constants might not be constant or common at all, everything we see is within our cosmic horizon - beyond might be weirder than one can imagine. Another lifeform might not even think about 'surfing the stars' at all, might not be carbon based at all. We must fix our own relations amongst each other before looking for other forms of life.

TBH it's more improbable were the only ones in our universe nevermind the multiverse, it's also likely there's super advanced cultures out there able to traverse the stars, but the fact is, space is so stupendously big, infinite even, and the fact it's ever expanding means that even those super beings most likely are confined to their local group of stars or galaxies.

Clearly laws of physics prevent travel in great distamces

"If, if, should, if, should" = very scientific!

IF they had survived, that's a big fucking IF

Remember what Hawkings said about aliens?

Cox by name and nature.

After Covid I realised most scientists talk out of there there bottoms but like the sound they make.

Scientist: Imagine what they would be like Alien: welcome to my universe 🌌

Most signals likely too advanced to be detected. Those that have been detected have been covered up.

I've seen arguments that life on earth came about far earlier in the lifespan of the universe than it should have. Another interesting suggestion, which would increase the unlikeliness, would be the rarity of phosphorus (an element that is mandatory for life as we know it).

They are walking among us undetected. Even the movie, "The Predator" could make themselves invisible..

Humans are talking about Having their conscience Uploaded into computers By 2045. Yet they be like "wheres the Aliens?"

Unless we are quarantined by the galaxy...

One thing to keep in mind is that any signals we detect in space does not travel faster that light. So if there is an advanced civilization several hundred million light years away, then we are only going to see their signals hundred of millions of years later after they made them. So maybe we just haven't waited long enough to receive those signals 🤔
