New to this and was thinking about extreme cases to help me get my head around how this all works...need help..(adsbygoogle = window.adsbygoogle || []).push({});

Imagine we have an object with mass moving along. Not that this is possible, but what if all other mass in universe was somehow utilized in some nuclear reaction so ALL energy in universe is used up to accelerate this one object to maximum speed.

Even all the mass in object is used up except for the last smallest atom/sub atomic particle. So we are left with a single particle speeding through space at almost C.

Ok, now at this point how does the particle know that it is not stationary ? And since there is no other stuff out there anymore how is there really and kinetic energy to be recouped ?

At this point isn't the total energy of the whole system down to zero ?

I need help in laymen's terms understanding the progression of total energy in universe during this scenario, and if it is still there at the end, and if so in what form ?

Thanks
