my theory states that light cannot be bent by gravity, it's massless
Quote from: timey on 13/02/2016 09:34:53 A caesium atom has mass. But the difference in energy between the hyperfine ground states of a cesium atom is not mass-dependent.Nor, come to think of it, is the period of a pendulum!
A caesium atom has mass.
Correct - they are both gravity related, and gravity causes changes in the rate of time...
The frequency of light reduces in a reduced gravitational field, because it is not experiencing any potential energy.
If the laws of physics are the same in all references, the bond length for hydrogen gas is an absolute that will be the same in all references.
No, I am 'not' saying that the light is 'bent'... (my theory states that light cannot be bent by gravity, it's massless) ... I'm saying that the light is gravitationally 'shifted'. And yes, that a 'change' in the rate of time is occurring. That physics is calculating this 'change' as being slower. This is causing the appearance of a length contraction. If you calculate under the remit of this 'change' in time as being to quicker time. Then you can see the length has not contracted. The contracted 'time' has caused the constant speed of light to cover the distance a bit quicker is all.
Ah Colin - well I hadn't been going to post the maths only for your benefit, which is just as well. It would seem you are telling me that you are not really all that interested.
The pendulum has a shorter swing being subject to less gravitational energy at elevation.
