  • In this video I show you what would happen if the earth were to be hit by a grain of sand going 99.9% the speed of light. I talk about the physics of it and then I try bigger objects hitting earth at near light speeds.

I wonder what will happen to our world and people if someday in the future something like that would happen...

      Well there was a slight difference: The tear drop was made of ultra dense and hard material that couldn't even be scratched, and didn't even slow down on impact. So it would be quite destructive compared to regular materials that do get destroyed and slow down on impact.

      @@IdkYoYo What is likely to happen (grain of sand going 99.9999 and some 9's percent speed of light) hitting the earth is that while the grain itself would likely lose cohesive structure, it's own time is seriously dilated, it will have gone through the earth completely in a microsecond from its own sense of time. As measured from Earth, at 3x10^8 meters per second, and Earth has a radius of about 6300 kilometers? Trying to do this from memory... 6378 km so not bad memory. Anyway, from Earth vantage point it would seem to take 20 milliseconds to go through Earth.
      Energy can be depleted by a shockwave but that depends on the velocity of a shock in rock, so I'm not going to try right now but the only energy transfer could be to the atoms directly in front of the grain of sand and they will be compressed and stuck to the grain and start traveling with it; a HUGE transfer of energy accelerating to .999999 speed of light more or less instantaneously so in very likelihood what comes out the other side aren't the same atoms that went in, but the bundle of energy will go through the earth and popping out the other side will be approximately the mass and energy that went in but having exchanged some atoms along the way.
      The tremendous energy to accelerate an atom will be taken from the trailing atoms and they'll probably just stop.

    I remember finding a site back in the mid 00s which included an app where you could find out the results of hypothetical meteor, comet and asteroid impacts with Earth, it allowed you to select the composition and size of the impactor and enter a handful of other variables like speed, trajectory, and whether it struck land or the ocean. It also imposed upper limits on everything to provide more real-world results, so no 100 mile wide, tungsten asteriod traveling the speed of light scenarios allowed. Of course, after seeing what damage smaller rocks would cause regionally, I scaled up for planetary mayhem, and got pretty good at destroying all life on the planet, but there was a single time, don't recall the numbers I plugged in, but it was an iron asteroid at the upper size limit, and the results were all Earth's oceans were vaporized. One happened that one time and regardkess of what I tried I was never able to repeat those results again.

    I'd like to see you use this computer program to simulate the creation of the Carolina Bays as proposed by Antonio Zamora's theory.
    (Secondary impacts of ice balls created by the initial meteorite impact on the Laurentide Ice cap.)
    Would that be possible?

    warp math has been done by nasa some years ago i got a copy and spent 2 weeks at whiteboard i believe i cracked some symbles value. Anyway it would be interrsting grain of sand visual since now theres no speed limit. Maybe ten time light could look cool.
    Anyway thats a fancy simulator you have.

    I got one for you...recently there has been a discovery of two craters that may have been related to chicxulub. Can you please show a simulation of what the earth would experience if it had been bombarded by not just chicxulub, but also the nadir and boltysh asteroids at nearly the same time? It doesn't appear that one has been made yet, and it would have been very bad for life on earth if it turns out that the theories are true.

    There was an opportunity missed here to teach about the special properties of light speed. Instead of increasing the mass, increase the speed from 99.9 to 99.99 then 99.999... even a grain of sand could wipe out the earth if it is close enough to light speed.

    Cool thought experiment! So what happens after the event? Over time, wouldn't it cool down and the remaining micro particles begin to merge due to gravitational attraction? Possibly recreating the Earth while incorporating the matter from the colliding body? A new, slightly larger Earth? With potentially new compounds from the donor. Perhaps a new form of life would emerge. Like the transition from dinosaurs to humans?

    I read a book a few decades back about an advanced species that keeps attacking earth. Humanity rebuilds and finds its way back into space and eventually find allies and start to fight back. When they finally locate the homeworld of the aggressors, the humans launched 500,000 metric tons of Mars dust @99.92C, ( Poetic justice for the total annihilation of the Mars colony ) timed to split up and spread out so as to cover and hit half the planet, twice, half a rotation apart. (I don't remember if it was 500Kt twice, or split in half though) Long story short, it took out every ship and station in orbit, roasted the surface to over 700 degrees c to a depth of 100 feet, +/-, vaporized the oceans and blew away most of the atmosphere.
    It was glorious, lol.
    Love to see this played out in your simulator. Those damage estimates seem very high compared to what I just saw here.
