Like.
Even after 50+ years of Apollo of which I am a proud beneficiary I am sorry to see the waste of taxpayer resources by a select group of... -
UUnclear Engineer replied to the thread What happens when your warp drive fails? Scientists have the answer.There had been a real question about whether antimatter had the same mass as regular matter. Some had wondered if it had negative mass...

UUnclear Engineer replied to the thread James Webb Space Telescope finds our Milky Way galaxy's supermassive black hole blowing bubbles (image, video).If regular matter is moving past stationary dark matter, it seems reasonable for the dark matter to be gravitationally attracted to it...

UUnclear Engineer replied to the thread James Webb Space Telescope learns how a cosmic phoenix cools off to birth stars.Extremely speculative that dark matter can emit or absorb "heat", at least in the form of photons. Remember, it is "dark". Other...
