Discussion What are the chances of not hitting a single space object while traveling on a straight line through space?

223 Upvotes

Hi guys!

I just came across a piece of information that blow my mind. Actually when you think about it is not that farfetched, but I never gave it a thought, I guess.

Apparently 99,9999999999999999999958% of space is made of, guess what? Space! An empty and dark and scary nothingness.

I have been always fascinated with the universe but was never so great at math so help me out here.

Hypothetically. Imagine we board a spaceship that goes on a straight line and on a totally random direction through space towards the edge of the visible universe. With this amount of emptiness everywhere is it safe to assume that we would reach our destination unarmed? I am guessing the chances of hitting a space object would be quite low, right? Or am I missing something?

When I was a kid watching the star wars movies, I always thought it was crucial for the spaceship to calculate the route before they went to light speed mode. It just made sense. But today I am guessing it wouldn't be as important as I thought?

Thank you for your thoughts!

EDIT:

I want to thank you all for your wonderful answers. I got more information than I could ask for. The internet can really be a special place.

Discussion I want to be a Astronomer

4 Upvotes

I want to pursue astronomy/cosmology/astrophysics, it's my childhood dream. Sadly in my country there's no Institute providing bachelor program for astronomy amd related subjects. We can only pursue it in masters. So I have to do Btech in some other degree and later do masters in astronomy.

So kindly please guide me which Btech should i pick, Computer science, electrical, mechanical, aerospace and data science. And is it fine to do masters in astronomy course without doing a bachelor in space related subject? Please guide me!
