Why all these sightings are never accompanied with sonic booms? If something is moving that fast through the atmosphere, there must be a sonic boom. Or is there any way to suppress this? At least theoretically?
- andrewflnr 8y agoI do remember reading about an airframe designed to produce two sonic booms that cancelled each other out.
- ramgorur 8y agoYea, looks like it's possible to some extent. https://physics.stackexchange.com/questions/270969/is-it- https://physics.stackexchange.com/questions/270969/is-it- possible-to-noise-cancel-a-sonic-boom
- partiallypro 8y agoNASA is actually working on this, if I remember correctly. They want it to be a "low boom," apparently it's still a work in progress. https://www.washingtontimes.com/news/2018/nov/6/nasa-quiet-sonic-boom-tests-rattle-galveston-texas/ https://www.washingtontimes.com/news/2018/nov/6/nasa-quiet-s...
- DonkeyChan 8y agoSeparating a pocket of space-time from itself, then moving that. Which would also effect inertia. I suspect that moving space-time around itself would introduce totally different shearing effects but maybe those could be mitigated using special non-physical(or physical) geometry, like aerodynamics but for space-time.
