I've been accelerating away from earth at 1g for 43 years, and haven't gotten nearly that far

I never thought about the fact you'd be able to see the CMB. That's really cool. Great video.

For the record at 99.7%(c) if a single grain of space dust hit the spaceship, the spaceship would literally undergo nuclear fission. All of the materials would turn into a ball of plasma and gamma radiation.

I laughed too hard at the first rocket falling over and exploding 😂

If you had indeed such a spaceship and flew the 2.2 million light-years to Andromeda, accelerating for the first half of the journey and then turning the ship around to decelerate with 1g during the second half, it would take only about 27 years in the frame of the ship. So, one could travel to the Andromeda Galaxy within a human lifetime, whereas in the frame of earth 2.2 Million years would pass.<br>To give some numbers: Time elapsed on earth / Velocity [% of c] / Time elapsed in the spaceship<br>1 years / 72.4% of c / 0.87 years<br>2 years / 90.4% of c / 1.42 years<br>5 years / 98.3% of c / 2.25 years<br>20 years / 99.98% of c / 3.55 years<br>100 years / 99.99% of c / 5.08 years<br>1000 years / 99.9999% of c / 7.28 years

And this is how you only age 8 years while over 4000 years have passed on earth . This is how you time travel .
