I have looked at this question for some time. We are given redshift for SN1a. From that there is not a simple velocity calculation v=cz unless the SN1a is close by. Cosmology and the scale factor need to be taken into account. Does anyone have a simple way to go from redshift to recession...
Naive and simple yes. General relativity is about acceleration and gravity. Special relativity was written as being about velocity and the velocity of electromagnetic waves. What if I update my thinking about SR to GR standards and make it about velocity and the velocity of gravity? Then all...
Yes, we see slight effects at micro levels in current astronauts. I was thinking about a more noticeable age difference. To answer two replies at once, the twin staying on Earth is still moving relative to the universe or cosmos. We know it is in the thousands of km/s range. This reduces all of...
It only depends on the velocity of the traveling twin. If that person gets anywhere near the velocity of c (compared to the universe), that person will suffer from time dilation and will lose some heartbeats, etc in aging. So that person will be younger. However, the twin on Earth is also...
Every gauge boson is within a field and carries a force. Higgs is a scalar (spin 0) boson. I am not sure which category a graviton (spin 2) would fit into, but it surely would carry a force. Is it possible that Higgs carries a force that we have not recognized yet?
