We're multiplying a very large number (number of planets) with a very small number (chance of intelligent life). The margin can make the answer go either way.

Why do you think the chance of intelligent life is a very small number? Considering we know of several million species, the chances are that we are right in the middle of the curve, and can't recognize the vastly more intelligent species the way an ant can't recognize our intelligence.

How is the number of known species correlated to the probability of life emerging? As far as we know, life emerged only once on earth, and all species evolved from a single common ancestor.

Watching this is ... hard to find the words to describe it. It's insane! It shows us how mind bogglingly vast the universe is and how we're literally nothing compared to it. Paradoxically, it also makes me feel incredibly potent and capable as a human being in that being this small we can know so much! Your size is to the distance of that distant spiral galaxy (420 Mly - 10e24m) as a neutrino is to you (effective cro…

we're literally nothing compared to it

Yet, here we are, made of it.

Some of that zooming in made me feel pretty damn uncomfortable. It really is f'ing massive out there huh. Makes me wonder what this is all about, I'm sure it's something, I wonder what. :)

It's just so crazy to me to see a galaxy 420 million light years away. That is so much time for what we're seeing to have changed. I presume life can form within that window given the right conditions, so to some degree it just feels a bit sad that the distance is so great that we can't actually see what may exist in this moment that far away

Given that the speed of light is the speed of causality, technically it's not really 420 million years in the "past" in any meaningful sense. The present is relative, not universal. The collected light we see in our telescopes is a lie about a particular universe that will never be, at least in any tangible way. On a cosmic scale, every spot in the universe sees its own unique sequence of events going on around it, a…

Yes, it is. It is 420 million years in the past in our frame of reference. The link you posted is about how frames of reference of other observers might differ from ours. However, doesn't make the notion "420 million years in the past [in our frame of reference]" any less well-defined.

Fun to imagine someone or something out there mapping us as well. What a cool video. I think one of the best things about space travel will be the loss of ego we go through when we really understand how vast the world is.

Apparently psychedelics can cause the so called ego death. I wonder if it’s the same driving force: a realization of how vast and limitless the world is.

That effect is temporary, but yeah you can get there. In my experience psychedelic users are some of the most egotistical people on earth. The cycle they live in is a nasty cage.

That we can know anything at all is a miracle in itself. It could have been just fine evolutionarily for us Earth creatures to be no more than Large Action Models with no inner experience, but somehow we ended up as these perceiving, cogitating, apprehending beings.

“So God created man in his own image, in the image of God he created him; male and female he created them.”

How arrogant and silly to look at these incredible pictures and think “Yep, this was all made for ME. I am the center of the universe!”.

So you're saying out of the trillions upon trillions of stars that the chances are no life can think but us? I think the odds are that at least one of them does.

There may be countless other planets with intelligent life right now, but... if it took them millions of years to evolve... and they're millions of lightyears away... we might have to wait millions of years for signals to reach Earth from the eldest civilizations in the closest galaxies.

Given the timescales involved and brevity planetary conditions perhaps life is unlikely to observed nearby a star system.

Perhaps instead it is to be observed in energy preserving vessels (i.e. emit nothing) in transit to the next fuel stop (a planetary system). Perhaps dark matter can be explained by the congested highway of these unobservable vessels.
