Define "larger".

It's more like tens (or perhaps hundreds) of thousands. With millions of civilizations, randomly spread, there would be a high...

Another point I would make is that saying that the observable universe is "teeming with life" is not a very useful conclusion. If, say...

An integral is an antiderivative. The only thing you need to check is that: $$mc^2\frac d {du} \bigg...

Possibly momentum in the wrong direction - the best sort for New Year

I think this is the integral you are attempting to compute. If so, I'd do it by inspection. For any integrand with a ##1/f^n(x)## it's...

You do, however, throw lots of words together to say something simple. For example: All that says is that we need a time parameter to...

This is basically what you're asking: https://arxiv.org/pdf/cond-mat/0101157 A global momentum measurement of the screen only yields...

The Fermi paradox is specifically about advanced life able to make contact with us. This is different from the origin of life, but life...

This is a good example of the principle of conservation of thread momentum, requiring no ongoing impulse from the OP.

In a more general context, a golden rule of using probability theory is that you understand the sample space. In this case, we simply...

That sounds like a personal theory to me!

Exactly. That life appeared quite quickly on Earth could mean that it's really easy (as Dave and phyzguy say, abiogenesis could happen...

The thing to remember is that, if new life formed today on Earth, it would get eaten very quickly. So you can't conclude that life only...
