- semi-extrinsic 10y agoThis. Diamond is one of the stiffest materials in existence. It has a sound speed of 12 000 m/s. Lightspeed is 300 000 000 m/s.
- sangnoir 10y agoHow about observing a quantum-entangled particle 1AU away from its partner? Can the speed of information surpass the speed of light? I'm a physics noob so I wouldn't know about research in the field.
- FreeFull 10y agoAs far as we can tell, the effect of measuring an entangled particle is at least 10000 faster than the speed of light. According to theory, it's instant. You can't use it to transfer any information, though.
- dragonwriter 10y agoAt any size, there is no such thing as "completely non-elastic", but at those sizes, pretending that some things are completely non-elastic is no longer a tolerable approximation.
