Re: Ever get the sense...
OK I accept the challenge.
Grand piano is about 500Kg. Lets skip over the messiness of colliding 2 of them and just throw a single piano to the ground at 99% speed of light. It hits with about 2.7E20J of energy which is about 67000 MT or 1350 times as big a bang as the biggest nuclear bomb ever exploded.
Putting it another way a piano at 99%C hits roughly as hard as a 2E12 Kg asteroid coming in at a modest 15 km/s or about 0.0001 as much bang as the dinosaur killer of 65 million years ago.
