Helio reacted to Admin's post in the thread Astronauts could mine asteroids for food someday, scientists say with
Like.
Material harvested from asteroids could be used to sustain astronauts during long-duration space missions. Astronauts could mine... -
Helio replied to the thread Could Earth's 'evil twin' Venus carry a dire warning about climate change?.In "The Secret Life of the Universe", Natalie Cabrol (Dir. of Car Sagan Inst. at SETI) has a chapter on Venus and habitability. She...

Helio replied to the thread Argument by analogy.1) Inflation theory itself occurs around t=1E-35 sec. so what I read is that it separates any two regions (points) so quickly that they...
-
Helio replied to the thread Argument by analogy.I don't really understand how Inflation actually helps. The idea is that two points in space that is expanding away from each other...

Helio replied to the thread Could Earth's 'evil twin' Venus carry a dire warning about climate change?.This is why science plays an important and unique role. Objective-based hypotheses are as good as knowledge can get. This is where...
-
Helio replied to the thread Could Earth's 'evil twin' Venus carry a dire warning about climate change?.Yes, that's an important question for science. I think there were a number of factors: His approx. 12 years of college taught him not...

Helio reacted to Unclear Engineer's post in the thread Could Earth's 'evil twin' Venus carry a dire warning about climate change? with Like.
At least this article does say that Earth is unlikely to be turned into Venus by humans. But, it seems to really short-shrift the...

Helio replied to the thread Could Earth's 'evil twin' Venus carry a dire warning about climate change?.Yes, though a = 0.723AU for Venus, so it receives 90% more solar radiation. No small matter. Right. Did I miss plate tectonics...
-
Helio replied to the thread Argument by analogy.Right, the dipole applies to your point — our net motion relative to the CMBR, which is, I think, the same motion relative to the Hubble...
-
I have never read anything about CMBR having an inherent dipole for a motionless observer, the anisotropy being due to a non-homogenious...
-
I seem to remember being taught about 70 years ago that no emulsion is permanently stable. Most (if not all) emulsions can be broken...
-
Helio replied to the thread Argument by analogy.Don't milk cartons still say "homogeneous" ? Perhaps not. I should look. If I see heterogeneous milk, then I know to toss it out...
-
Helio replied to the thread Argument by analogy.Yes, the dipole. But, I assume this dipole is a direct result of our movement in the Hubble Flow, so the CMBR is static (co-moving)...
-
Helio replied to the thread Argument by analogy.You're always welcome, Cat. Your professional touch is appreciated, as well as you patience. I'm neither an astronomer nor a...

Helio replied to the thread Argument by analogy.Oops, thanks. [I knew better.] Are you referring to the Hubble Flow?
