If things such as quantum entanglement and the expansion of space can travel faster than light, then why can't gravitational waves, which are vibrations of spacetime? I thought that only matter cannot move through space faster than light. Also, has it been 100 percent proven that gravity waves...
It seems to me that you would have to place two plates so close together and perfectly parallel for the effect to be visible. Correct me if I am wrong.
I have heard before that for every 1 billion antiparticles there are 1 billion and 1 particles of normal matter. Has this been observed directly or just predicted? Have we only observed antimatter through its creation on earth?
To me, it seems that with our current technology it would be difficult to observe the speed of gravitational waves. Can anyone correct me if I am wrong?
How could it be tested that there exists true randomness in the universe? One could simply argue that the is information that we do not posses that causes the outcome of a measurement to occur, right?
What I mean by this is how were the laws of quantum mechanics used to predict that the higgs boson would decay into 2 photons or 4 electrons. I understand that the higgs boson transmits the higgs field, but why would a particle that transmits the higgs field have to decay in that wayand not some...
