I was calculating the damage of weaponized high speed rail and wolfram alpha told me "infinity joules" and was confused where I messed up the math.

@ShiitakeToast @futurebird @foone
Probably still in the blast radius.
-
with the minor downside that if the brakes fail you'll hit LA with more kinetic energy than a supernova, instantly destroying the earth, then the rest of the solar system and any inhabitable worlds within 53 parsecs.

Relativistic weapons are a hell of a drug.

This, by the way (looking up some formulas on Atomic Rockets and a few google searches on the mass of trains and speed of the Large Hadron Collider) is more math than was done on the Hyperloop at any point
-
@foone 13 milliseconds to a stationary observer.
-
@uep true! it's like the "blow up the asteroid" problem: Instead of a big hit of kinetic energy when it hits the ground, you get millions of pebbles carrying the same energy burning up in the upper atmosphere. So instead of getting flattened you get cooked alive
-
@plaidtron3000 right. Compared to an observer on the train going the opposite way, they're going EVEN FASTER
-
@mattdm @ShiitakeToast @futurebird in this case the blast radius is measured in lightyears, so yes.
-
@munin I think that's Juuls. He wanted to vape forever
-
@dr_a yeah. As you get closer to c, your mass increases. at c, your mass is infinity, as is your kinetic energy.
-
multiple people have pointed out that even if the breaks work, they'd have to dissipate 10^46 joules of kinetic energy, which is a LOT of heat to dump into the area.

@foone it's okay, it's a dry heat

@psilocervine very dry, as less than 10^27 joules would flash-boil all the earth's oceans
-
@foone good news! you won't need brakes, because the hypersonic bow shock in front of the train that is carrying on nuclear fusion of air molecules will definitely slow the train all on its own
-
(it will also destroy the train almost instantly, but the net momentum of the debris will definitely decrease over time)
-
@tess yeah it'd very quickly stop being a "train" and become an "expanding plasma cloud"
-
it'll be the hot new summer blockbuster
-
@munin the hottest summer since records began, which will be that summer, as all the records will be instantly evaporated

@foone I assume you already saw the Bobbybroccoli video about it? it's excellent
