Like.
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...

Jjavisot reacted to pinball1970's post in the thread Alien life, probabilities, and interstellar propagation of human life with Like.
That is not entirely correct. We do not know how life on earth began specifically but there a few ways that this could have got going...

Where do you get that from? It's more like life arose in many places on Earth at the same time after enough time had passed for several...

Jjavisot replied to the thread Alien life, probabilities, and interstellar propagation of human life.Yes, the iron-sulfur world hypothesis, the RNA hypothesis, the RNA-peptide world hypothesis, etc, are several proposals for abiogenesis...

Jjavisot reacted to mr3000's post in the thread Alien life, probabilities, and interstellar propagation of human life with Like.
It seems to me that if life started on earth exactly once in 4.5 billion years, then it is an extremely improbable event that is a very...

Jjavisot replied to the thread Alien life, probabilities, and interstellar propagation of human life.It is a difficult question to answer; abiogenesis is the synthesis of life from inert matter, but we do not know any mechanism of...

Jjavisot replied to the thread Why Are You Still Here? A Curious Question."Why are you still here?" I don't know exactly. But I'm noticing that PF and the forums in general might soon have problems with the...

Welcome to PF. Please do take the time to read the rules, particularly the parts about speculative and non-mainstream theories. We can...

Jjavisot reacted to PAllen's post in the thread High School Estimates — True Size of the Universe? with Like.
You can, but many people have a hard time picturing how this is possible. My suggestion provides a way to picture this that was helpful...

Jjavisot replied to the thread High School Estimates — True Size of the Universe?.(When I said it was a property of all spacetime, I didn't say it was a property of all spacetimes. We're talking specifically about an...

Jjavisot reacted to PAllen's post in the thread High School Estimates — True Size of the Universe? with Like.
Actually, it is only a possible property of very special spacetimes. It is a feature of geometry that is hard to visualize in a 3x1...

Jjavisot replied to the thread High School Estimates — True Size of the Universe?.As Ibix says, the bread example isn't very good, but PAllen's example is brilliant. There's no contradiction between having an infinite...

The problem with this one is the finite size. People conflate the increase in volume of the finite lump of dough with the expansion...
