#1608: That doesn't add up.

Cosmic rays come from supernovae. That part makes sense.

This one does not:
Helder and team looked at the leftovers from a supernova called RCW 86 with the European Southern Observatory's Very Large Telescope. The star exploded about 8200 light-years away in AD 185, and was recorded by Chinese astronomers.
If the star is 8200 light-years away from us, and it exploded in 185 AD, that means the light from the explosion hasn't reached us yet. It's only been 1,824 years since 185 AD.

Now what the writer meant is that the light from the explosion, which happened 8200 light-years away, arrived here in 185 AD. But in order for that to happen the star in question had to have exploded 8015 BC.

Worst part? It was written by a staff writer for Space.com. *sigh*

Incidentally, Congress will be exempted from participation in ObamaCare. They'll continue to have the same super-excellent health coverage they've always had.

So while you're sitting in the waiting room for five hours in order to have a broken bone set, just remember that your Congressman doesn't have to wait. I'm sure that'll dull the pain of the injury.

At least it'll make you so mad you forget about the pain.
