Beautiful lighting.  :)  Today my color has been green.  Green chrysoprase that is, collected from a nearby creek.  Today I worked on some pieces with a diamond cutting wheel.

Atmosphere Scripting

32269 I wanted to see what effect CO2 levels in atmosphere would have, to I tried an experiment. As SpaceEngineer says, calculating the greenhouse effect is very complex and not something that SE does.  But if you want some intuition for how it works with varying CO2 or other greenhouse gases, then...

32286 When I saw some of the tainting being done in some industries to skew the numbers, thats what got me down on statistics. Your comment and story reminds of people who dislike or even reject evolutionary theory because of atrocities with eugenics.  But evolution is not inherently good or bad, i...

32259 Scientists use statistics all the time to back up their research, yet few have any academic background in statistics to speak of.  This may be a serious problem (I have to say "may be", as I never did statistics at university myself and I regret it, so I can't really back up that cl...

AWYvmBVpU8M Abstract:   The region around the Galactic Center contains a well-characterized excess of gamma rays, which has garnered great interest as a possible signal of either dark matter particles colliding and annihilating, or a previously undiscovered population of pulsars in the stellar bulg...

32256 So "good" ways to render energy pretty useless would be to turn it into gravitational waves or neutrinos. Definitely.  I think this is roughly equivalent to saying that radiating energy in these forms is a good way to increase the entropy of the universe.  Probably the best  way to ...

32247 Indeed, yet it takes an extremely sensitive instrument to detect it!  How much energy could be "hidden" in frequencies we can't realistically measure?  Less than than 1eV/cm 3 , or in perhaps more familiar units, less than 10 -13  Joules per cubic meter, on average in the universe. ...

A-L-E-X , it's no secret or surprise that black hole mergers release a lot of energy in gravitational waves.  Detailed simulations of mergers and the gravitational waves they emit have been performed for about a decade, largely so that scientists can interpret the results of LIGO detections and tes...

32221 Who cares if casusation can be proved or not I do.  And so should you. Any scientist who says what you just did has ceased to be a scientist.  "Correlation = causation" is one of the most pervasive fallacies in science and human psychology, and it is absolutely important to understa...

Qr Bbpost I read that some computer simulations hint that the merger of two supermassive black holes may provide the impetus to generate a new universe (because it would have two horizons, and the new universe would be inside that second horizon.)

Where did you read that?
