relativity

look at me, actually drawing launch towers properly for once.

plugging some quick numbers into wolfram alpha, the energy required to propel a 100 metric tonne ship to 99% the speed of light is roughly 5.472×10^22 joules. this is equivalent to 1/9th the energy of the asteroid impact that killed the dinosaurs, or 225,000x the energy of the tsar bomba, the largest nuclear bomb in history. and that’s not even to mention the energy required to stop, come back, and stop again.

which is to say, sedna’s being a little optimistic in her dream here.

whenever you think you’re the best at something, just remember there are 1,000,000,000,000,000,000,000,000 (10^24) star systems in the observable universe. there’s almost certainly someone out there better than you. ;)

unfortunately, trappist-1e is over 40 light years away, so it’s going to take a while for the rest of humanity to hear the wonderful news,

now that i think about it, when you have a head that big, a laundry basket is actually the perfect size for a helmet.

if only sedna had powered the rocket with whatever anti-gravity magic is in her ponytail, then she wouldn’t have had any problems.

pity they don’t teach rocketry in primary school. would’ve made maths class just a tad more interesting.
