I didn't make any claim about life. I just wanted to challenge the statement about the universe being finite. I also agree with the other commenter that I'm not sure we can even be sure the mass is finite, but also happy to be enlightened.

The context of this conversation is probability of generating life. Debating theories on dark energy isn't relevant since it's not dense enough to generate life.

The context isn't relevant when I'm correcting a fact, at least as we/I currently understand it - the universe is infinite. I'm wasn't making a statement about dark energy, or life.

You're misinterpreting the semantics of finite mass in this conversation about abiogenesis by taking it out of context of conversation.

You are ignoring the spacetime part of the universe, which in definitions of the universe being finite or not, is probably far more relevant than the mass.

Is it that simple? Empty space has energy (dark energy) and E=MC^2 means energy and mass are interchangeable. Hence infinite space does imply infinite mass.
Not a physicist, so I'm probably dead wrong. But I would like to be enlightened.
Claiming infinite space has infinite possibilities for life is quite literally a Celestial Teapot argument.
