Hey vsauce, Micheal here
assuming you’re stationary and a rose is moving directly towards you, how fast would it have to be going to blueshift into looking blue?
what would happen on impact?
See https://mander.xyz/post/17123445 and in particular https://lemmy.blahaj.zone/comment/10334166.
It would have to be moving at relativistic speeds, and given that F = mv² the velocity is the dominant factor when it comes to force. So, you’d probably get vaporized.
That is definitely not a correct expression for force. It doesn’t even have unit of force. Do better. smh
