That the moving mass energy gets up to > 1000 of the rest mass seem pretty wild for me but that example of the "Oh my God" particle was really mindblowing.
Thanks!
Trying to calculate the relativistic energy based on near light speed it seems like the final speed of the Marsmallow has to be more than 99,9% (but probably not more than 99,99%) of the speed of light to achieve that kinetic energy equiv. to 1000 hydrogen bombs (depending on the Marshmallow weight and bomb size. ....)
Well, the possibility to accelerate an object for something so dense/heavy, its on the edge of becoming a black hole is probably the explanation I didn't grasp. Would have been interesting to see the assumptions behind the impact speed.
Speculation: the cosmic start spits (bursts) may be a candidate for high energetic particles
