I wonder what ever happened to that mantle that got shot up by a nuclear explosion. - Lemmy.World

I read somewhere it must’ve turned molten from the atmosphere, but l wonder if like little droplets of metal fell down to earth or if it was just vaporized.

Anything that wasn’t vaporized was likely launched out into space at speeds exceeding escape velocity for Earth’s gravitational field by a factor of 6. So if there was anything left after the explosion and wind friction, it’s out in space, probably moving towards the sun.

The high speed camera was intended to be used to calculate the speed of the cap. It was going so fast it was only captured in 1 frame, which is only enough information to put a lower limit on the speed.

How do you calculate speed at all with only one frame?

You dont, hence why only a lower limit could be established with a single frame capture.

Basically like saying “if we only got 1 frame, then it must be going faster than x mph/kph”
