Hi, I'm a 17 year old been out of high school for a year and I want to study space. I narrowed it down what I want is to be an astrophysicist and I was hoping someone can give me advice on how to take the first steps.

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.

Original Title: A new study suggests water first formed billions of years earlier than expected — as early as 100 million years after the big bang. According to these simulations, huge volumes of water, the primary ingredient for life, formed close to cosmic dawn — the moment the first generation of stars was born.
