Although it was a setback for physics, I'm glad the particle naming rights issue led to the cancelation of Pizza Hut's Superconducting Super Collider in the early 90s, so the Double Stuffed Extra Cheese Topping Quark ended up just being named 'top quark.'
as a hypothetical you could posit practically any distance. If you said "all the energy went into sending this one animal." I suspect that the math would produce such large speeds that you would have to count for relativistic effects etc.
but if you allowed that some energy went into making a crater, vaporizing rock, creating tidal waves, etc. then you would come up with a much smaller value
