Time is a measurement of the rate of change of processes. You might be assuming that time should be universal and someone should prove to you that it isn't. Why not look at it the other way around? The measurement of time is only consistent locally. Prove to me instead that this is wrong and...

You're speaking of the general theory of relativity and the special theory of relativity. Yes the process appears "slow" relative to another reference frame. The clock is simply another process.

Feenburg's Twin Paradox is another good one.

I guess I'll admit to having a problem with an inner event horizon to any kind of black hole. On the qualitative level, I think that if a point on the outer horizon surface does not age relative to a given outside reference frame, then anything inside of this surface is technically beyond...

PF mentors - please place a link to the main thread regarding "photon perspective" if you lock this one out. I couldn't find it. I think someone could pose an argument that the photon frame doesn't "experience" a change in time. I've always argued for that perspective in the past. But now...

I agree with your idea. Well, kind of... It only makes logical sense that an entity "traveling" (it would only appear to travel in this case) at the speed of light would not age at all - regardless of the distance covered... so the photon's endpoint and starting point are part of one closed...

At Fermilab, they are attempting to test the neutrino oscillation theory by shooting neutrinos to a detector in Minnisota which should "prove" that neutrinos have mass. I don't know why, but I think they don't. But like photons, they do carry energy so who knows.

Just like to add that there is a lot of speculation involving black-holes. Gravity is "causing" time to slow, but the other way to look at it is that the curved space-time (in the topological sense) is causing gravity. In 4d topology, the gravity is a result of the curvature. Energy present...

Nereid, Cool links - Kind of funny the way the news goes in waves! I tend to agree that celestial data may provide more convincing evidence, at least if gravity if very close to light speed (obviously if it were substantially different, the nova events and gravity waves would be tricky to...

- The gravitational effect of an oscillating mass at a given frequency, gravity should transfer this same frequency (or another harmonic one) to the smaller masses. This slight movement at a specific frequency is what would have to be anaylized, and then the specific phase difference would...

I have an idea of a cheap way it could be done. -In a vacuum tube, have two 1kg weights (for balance) on a small motor, and spin them really fast at a constant rotational speed. -Then at given distances from the spinning weights, have very small masses suspended also in the tube. -monitor the...

You know, with all the fancy gadgets we are building to attempt to find gravity waves from outerspace, you wonder why we haven't devised an experiment to measure the speed of gravitational changes on the smaller scale. I know it is difficult to evacuate a large enough volume to have a...

This is only my opinion of what a photon is... If we consider a multi-dimensional hyperspace (more than 4 dims, but total quantity of open & closed dimensions are not pert. to the picture) - the photon, any photon, is a closed reaction that spans all of the volume of space-time (including...

Yea, I just link the additional space-like dilation with the time dilation (both SR and GR time dilation). The dims perpendicular to the velocity in SR are stretched, but skewed and longer only in a light-like sense. In GR the dimensions are dilated and remain locally orthogonal. The tie...

I don’t mind at all - I would love to help (as long as it’s ok with the Mentors). I know it was a bit confusing on a few of the points, but if you forge through, it explains some of them. Time dilation is actually nothing new. It is a measurable phenomenon (with extremely accurate data)...
