Why don't we see Others?
I think the anthropic principle neatly explains both scenarios: why we're
here, yet nobody else seems to be.
If life nucleation density is arbitrarily low (e.g. 1/visible univers) we
still wouldn't fail to observe our existance.
It is also worthwhile to mention that
Hi all,
I have a query about Tegmark's argument I hope some of you might be
able to address.
First, let me say I am not a physicist or computer science person but
a humble sociologist with some lay physics knowledge on this topic.
Let me also say I find it a morally ghastly proposition that
There has been a huge amount written about the Fermi Paradox (why are
there no aliens) over the years, and I don't want to reiterate that here.
You can come up with scenarios in which intelligent life is common but
where they just aren't visible, but IMO such explanations are not very
