Paraphrasing: There are 100 billion galaxies in the observable universe, each galaxy contains approximately 100 billion of stars. It takes 100s of thousands years travelling at the speed of light to get from one end of the galaxy to the other. It takes 100s of millions to billions of years to get from one galaxy to another. And all those galaxies are moving away from each other at mind boggling speeds 73 kilometres per second.
It’s humbling. And we kill each other for silly reasons. We are so significant, yet so insignificant.

The crazy thing is that at a constant 1g acceleration you could get to the Andromeda galaxy in your lifetime. Andromeda might be 4 million light years away, but relativistic effects mean that only about 30 years would pass for you. Of course, constant 1g acceleration would require an unimaginable amount of energy (and something to thrust with). At 1.5g-s you could make it in 20.
