Hi, this is just a question I've had for years and have not been able to figure out because of conflicting information. I have read that space is expanding and that it's speeding up, but also have heard that in about 5 billion years our galaxy and Andromeda will collide. How is this possible?
Also, if a galaxy is moving away from another galaxy and each one is moving away from the other where does the extra space come from? At least this is what I got from watching a Stephen Hawking show some time ago.
Thank you,
Andre
