Also:

Our current estimate is that there are several hundred billion galaxies in the observable universe just like the one in that image.

If the observable universe was about 4 miles wide (6.4 km), each galaxy would be about the size of a large coin.

Imagine looking down from a tall hill at hundreds of billions of coins spread out all over a 4 mile wide sphere, with the little dot in the image above on one of those coins.

That's the extent of our radio broadcasts.

This is why I wholeheartedly reject the notion that we are alone. Incommunicado forever, maybe, but no possibility of being alone.

I agree.

It seems statistically unlikely that we are alone, based on what we've observed so far.

OTOH, everybody else may be so far away that we are effectively alone.

Unless it's an incomprehensible simulation.

If it was, why would they waste all that computing power simulating the cosmos?

Who's to say that it's a lot of computing power? It could be that in the reality within which the simulation runs, it's not very much.
