Alka-Seltzer and water in zeroG

Here is an interesting little side experiment from the International Space Station where and Alka-Seltzer tablet is put in to a sphere of water in zeroG. The results are actually some what surprising. The bubbles collect in the water sphere even coalescing into untimely two big ones.

Faster Than Light Neutrinos Video


There’s a common mistake that this is a problem for relativity but it is not. Relativity forbids is accelerating up to and past the speed of light but does not for bid particles that naturally travel faster than the speed of light. Such particles have been speculated about for decades under name tachyons.

The only real difficulty is that neutrinos have a small but real rest mass and so should not be traveling faster than the speed of light. In that case the issue is most likely with our understanding of neutrinos and relativity

Quantum Mechanics allows particles to skip part of space instantly and so could be clocked at faster than the speed of light while going sub-light through the space it actually goes through. This is the most likely explanation of this observation given calculations from India.  See Flaw Found in Claim of Faster Than Light Neutrinos

A video on the that the Meridiani Planum region of Mars

This is a video that provides evidence that the Meridiani Planum region of Mars landing area of the Rover Opportunity was flooded by a massive spill. With the area filled with highly acidic water. This is part of a major Martian geologic catastrophic event of global proportions. This event would have been a massive asteroid bombardment that changed the planet.
