Relativistic Spaceship

This dude made a simulation of what it would look like from a spaceship accelerating towards the speed of light. Click in the upper half of the acceleration slider to move forward.

    Well, your eyes would be fried well before you reach 95%. Apparently the blueshift would make quite a lot of ionizing radiation. Hard to replicate on your phone ;)

    Neat visuals but I don’t think this is in any way accurate… Tell me how I crossed all those lightyears in about 60 seconds while only traveling at around 95% the speed of light.

      Relativity? A light year is a measurement of distance, not time. A ship traveling at.95C would only take 4 months to travel 1 light year from the perspective of the crew. To outside observers it would take a over a year.

    After leaving it on for about 4-5 hours, and reaching several screenwraps worth of sigfigs, speed reset to 0, but time did not. I just wanted to see what happens, so that’s all I really wanted.

        The only known way to convert 100% of matter into photons, is a matter-antimatter annihilation. You are bound to encounter some antimatter over enough light years of travel, but it isn’t clear whether it would be enough to annihilate all your matter, and the ship’s matter (there doesn’t seem to be too much antimatter out there).

        At some much earlier point though, you’re going to receive such an amount of high energy radiation, that the whole ship and its occupants, are going to turn into a ball of plasma… including the engines, so no more accelerating from there on.

        That ball of plasma is going to collide with interstellar dust at quite high speed/energy levels, just like in a collider, with the particles breaking apart and creating a cascade, of photons and other particles, that will quickly decay and/or coalesce into other ones.

        So you will become a photon, even a lot of photons, and while some would escape in random directions, the plasma cloud would dissipate and slow down over some distance, becoming mostly interstellar dust itself.
