It's amazing to me how an interstellar-sized cloud formation looks very much like a cloud formation in the sky on earth.

Nature is very fractal, the same pattern occurs on multiple levels. You even see the same thing in human constructs.

It's so very unlikely that there aren't millions of other lifeforms out there. Sometimes I think that life could well have been just my soul and no one else, but here I am sharing this world with billions of other people, trillions of other lifeforms on this planet alone. So it is possible that more than one lifeform exists, that they share this universe and communicate in it. Why shouldn't this also be possible on m…

Of course there are other lifeforms out there, it's statistically implausible for it to be otherwise. What's also implausible is that, given the impossible vastness and hostility of interstellar space, that any will ever manage to contact us, specifically. Fortunately, we've got lots of crazy lifeforms here on Earth to keep us occupied, if we can take a moment to stop extincting them as fast as we possibly can.

First of all: the question needs to be qualified by what we mean by "out there". The galaxy? The observable universe? The entire universe?

The universe might be infinite, in which case: yes, there is life out there. We know the probably of life forming on any given planet must be greater than zero, or else we wouldn't be here. From this we can deduce the average volume which contains exactly one planet with life, which must be finite. Whether it makes sense to talk about what could be happening beyond the cosmological event horizon is another discussion.

If we are talking about the observable universe or an even smaller volume: How can you say it's statistically implausible without knowing the probability of life forming on any given planet? It might be incredibly small, yet greater than zero. Your line of reasoning is incredibly common but I can't help but feel like it's mainly driven by wishful thinking.

> Of course there are other lifeforms out there, it's statistically implausible for it to be otherwise. I'll grant you that once we have found a single other planet with life. Until then we're doing statistics on a single data point and no, the number of planets and galaxies etc are not sufficient to statistically determine the prevalence of life because as yet none of them are confirmed to have life. This is wishful…

This is only true if we believe Earth is special, which we have no bases. So I'll stick to statistics for now, thank you very much.

That's an incredibly detailed image.

Every single time I see one of these amazing space pics, it's hard not to get all philosophical and wonder about the size of space & time on cosmic scale, how small our earth is and how insignificant our regular problems are.

I don't care if I don't get to see flying cars or AGI in my lifetime but I will be very disappointed if our knowledge of space remains more or less the same as today without much progress.
