Looking Up, Near and Far
Two big things have come up in the last few days.
First, there's more water on the moon than we thought. A lot more. Perhaps as much as Lake Superior. That's the good news. The bad news is it's in the rocks and all over. There's a lot more moon than will fit in Lake Superior.
Carnegie Institute found hydroxyls in the mineral apatite. This was found in the rocks brought back from the moon.
The other interesting thing is bigger. Much bigger. Much, much bigger.
Some new research from Durham University suggests that errors in measurement of the Cosmic Microwave Background might change the composition of the universe. It might reduce considerably the amount that is made up of Dark Matter and Dark Energy. This might be interesting news for Dark Energy, since it appears to be accelerating the universe expansion, but the Dark Matter issues have bigger hurdles to cross. Namely, the missing mass in the orbital velocities of galaxies.
