Seems it could help with ionization, since early galaxies barely produced enough escaping photons. There are sound wave analogs in the... -
billslugg replied to the thread Cosmic rays have surprising amounts of antimatter. Is dark matter responsible?.I believe two .511 MeV photons are required in order to conserve momentum.

billslugg replied to the thread Gaia space telescope discovers 55 'runaway' careening away from stellar cluster at 80 times the speed of sound.Be careful when simplifying for the new folks. There is no air in space. Thus no sound. They will get confused. Kilometers per second is...

billslugg replied to the thread We have the satellite data to show climate change is real. Now what?.Are the numbers spiked? Interpolated? Adjusted in any way? Is this "thermometer data" held to a "tree ring" baseline like Mann did? Did...
