I personally think that GR's explanation of why ##M_i=M_g## is one of the most intellectually satisfying things in physics.

Give yourself time to think about it. GR is a profound change in our thinking.

There could have been some reason for ##M_i=M_g## other than GR, but nobody could come up with one. It was a mystery until Einstein...

I would call it a satisfying consequence of General Relativity. GR explains the mysterious reason behind ##M_i=M_g##, not the other way...

General Relativity hypothesizes that an object, appearing to accelerate due to gravity, is simply moving in a non-accelerated straight...

No. But the current understanding explains why the exact same mass is appropriate in both equations. That is one of the strong points of...

And if you have no choice, send it as a .jpg, and throw some other quirk like writing it backwards or Letter +1 or something.

You have several misconceptions about entanglement. First, entanglement is often a result of conservation laws and any number of...

Bertozzi even filmed a simple test of this, and somebody put it on YouTube:

Particles have been accelerated to near the speed of light, so it is known how much energy and force is needed. The results agree with...

Relativity says it must be. Relativity imposes a finite limit on the strength of materials, and that limit ensures that it is impossible...

The centrifugal force at the edge of the disk is proportional to the radius of the disk, which in this case is about 30,000 miles. Have...

The best way to avoid misleading knowledge is to be very careful what sources you look at (the best ones are textbooks and peer-reviewed...

Yes! It would not occur to me that AI would search through my old emails to find a password. I assume that it took advantage of you...

I'm not sure where this post might belong, so I just started a new thread. If there is an existing thread it should go into, please...
