Some day, 4 billion years from now our Milky Way is going to be smashed into by the Andromeda galaxy.
The planets from our solar system (EG: Mars, Jupiter...) may become part of another solar system.
It was interesting to learn that it takes our solar system 250,000,000 years to orbit the Milky Way.
These things interest me, because I was reading about global warming.
It seems that every 150,000 years the Earth's temperature cycles between near ice age temperatures and global warming.
They can tell by studying the Earth at the poles.
Core samples, taken from different levels of the ice, tell the secrets about the Earth's atmosphere over time.
We are in the warming cycle right now.
The Earth is going to get hotter, regardless of the greenhouse gases, because history shows thats just what it does.
But don't buy a beach house in Greenland yet.
It may take another 50,000 years for the United States to fall below sea level, again.
