billslugg replied to the thread Astronauts could mine asteroids for food someday, scientists say.The lightest and most efficient shield is water. It's low atomic numbers recoil and sap the energy out of the cosmic rays. Rock shields... -
billslugg reacted to Helio's post in the thread Astronauts could mine asteroids for food someday, scientists say with
Like.
If a small asteroid is used as a part of the spacecraft, it would not only provide water and, apparently, food, but shelter. A great... -
billslugg replied to the thread Why haven't we found intelligent alien civilizations? There may be a 'universal limit to technological development’.The paper is citing the Euro's inability to produce fuels from wind and solar, and their inability to mainstream the latest medical...
-
billslugg replied to the thread Argument by analogy.So the accelerated rate of expansion, greater than c, "baked in" a certain amount of anisotropy so that what little was left after...
-
billslugg replied to the thread Astronauts could mine asteroids for food someday, scientists say.Direct to human is going to present a challenge to make people satisfied. We will need advanced printers that can make crunchy cells...
-
billslugg replied to the thread Argument by analogy.Inflation expanded so quickly the hot spots could not even out. Yet, we needed to invoke inflation to explain why the CMBR is now so...
-
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...
-
billslugg replied to the thread Argument by analogy.I recall two mechanisms for the benefits of inflation. 1) Starting out smaller allows information to be moved brfore it gets too big...

billslugg replied to the thread James Webb Space Telescope watches a frozen, comet-like object shooting jets of gas.If I click on a title that promises a picture and when I get the there is no picture and I have to wait, forget it. It might come up in...
-
billslugg replied to the thread How sweet is space? The answer may reveal clues about how life began.If we put a group of elements in a jar, hit it with UV radiation, eventually we will have every single molecule could possibly be made...
-
billslugg replied to the thread An introduction to Refractional redshift, and how it was confused with gravitational redshift.Pound and Rebka swapped positions for source and receiver many times. Sometimes they had the emitter on the top of the tower and...
-
billslugg replied to the thread Argument by analogy.All inflation means is the universe had to be smaller than we thought at the start in order to explain the observed low degree of...
-
billslugg replied to the thread Argument by analogy.I have never read anything about CMBR having an inherent dipole for a motionless observer, the anisotropy being due to a non-homogenious...
-
billslugg replied to the thread Argument by analogy.No, I am referring to the Earth's abolute velocity being meaureable in magnitude and direction. There is one direction blue shifted, and...
-
billslugg replied to the thread Argument by analogy.Space tells matter how to move, matter tells space how to curve. There is an absolute velocity in space, referenced to CMBR.
