When we collide with Andromeda galaxy in about 3 billion years none of this will matter. Glad I won’t be here to worry if we get slammed by another star!

Still, the night sky will be spectacular!

According to the article, the Milky Way’s diameter is 100,000 light-years. That’s about 877 million light-hours. Using the heliopause as the limit of the solar system, its diameter is about 34 light-hours. So, the Milky Way is about 25.8 million solar systems across.

There is actually not much greater chance of stars colliding during a galaxy collision than now. They are pretty much flying around randomly between each other just orbiting the Milky Way. There's just too much space between stars for it to be occur with any reasonable likelihood.

Imagine our star is the size of a marble (1 cm across). Then the nearest star to our sun would be another marble 180 miles away. Double the approximate number of stars due to one galaxy flying through another, and that's still a very small target.

"Professor, was that millions or billions of years?"

I hope Keith Richards has his affairs in order.

Dude, I plan on still being here.
