[Edit: missed the reference to particles. Particles hit earth every day with .9999999c. They are called cosmic rays. Occasionally, they are so energetic that one proton carries as much KE as a thrown baseball.

If a 1 gram object had the speed of the fastest cosmic rays, it would hit earth with an energy of about 1 hundred million gigatons of TNT
]

For Q1 and Q2 below, imagine two objects traveling on a perfect head-to-head collision course.

Q1. Is it possible to calculate the energy released if two 1,0 gram objects, each traveling with the speed of the fastest cosmic rays, would hit each other?

Q2. What would happend if two 1 gram objects, one traveling with the speed of .9999999c and the other at 1c, would colide with each other? Is it possible to calculate the released energy in this impact?

Thanks :)
