Experiments showing mass dilation???

Question

Have there been any experiments by scientists demonstrating mass dilation??

In regard to special relativity

Answer 1

I think you're talking more about mass *increase* than mass dilation. As some massive object is accelerated closer and closer to the speed of light its relative mass increases. This goes on all the time in high-energy particle accelerators. When some subatomic particle gains a velocity approaching that of light its normal decay time increases slightly because its mass has increased.

Answer 2

An electron masses 511 KeV/c^2. When Ernest O Laurence's cyclotrons pushed past about 50 KeV Special Relativity threw off synchronization between orbits and microwave pumping frequency, hence the synchrotron for higher energies.

For an electron of rest mass m_0 in principal quantum #n with an atom of atomic number Z,

m = (m_0)/sqrt[1 - (Z^2)/n^2c^2]

Relativistic mass increase in mercury pulls in its 6s2 electrons leaving only a filled n=5 shell at the periphery. It looks like an inert gas and is a liquid metal down to -38.9 C.

Answer 3

Yes, my college physics professor demonstrated the relativistic increase in electron mass with speed to every class he taught.

Answer 4

there no reports of mass dilation maybe itz time dilation....
well in special relativity einstein theorize that as an object approach to the speed of light, its mass increases....

Answer 5

are you referring to the uncertainty principle or something relativistic?
