Hello,
I have read somewhere that the next major step in physics will be unifying general relativity with the quantum theory. Does anyone know about such? I wanted to know a bit more.
I have read about such in the book by Stephen Hawking "A Brief History of Time".
Thanks,
I.

P.S. My apologies for the wrong prefix.

I think almost everyone in this forum knows about that.

The problem you're talking about is the most famous in modern physics. It's not Quantum Theory of Relativity, but rather Quantum Gravity, though no one really knows whether that is the right way to unify both fields. The idea is that gravity cannot be quantized, and thus it's different from the other 3 forces (Strong/Weak Nuclear force and Electromagnetism). There is String Theory and Quantum loop theory among many others. There is a lot of speculation in all this theories, and we still don't know if there is such theory exists. If that problem is solved, we may have achieved the "theory of everything".

Thread 'Can this experiment break Lorentz symmetry?'

1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...

Thread '1-Way Speed of Light'

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...

Thread 'How can a black hole absorb matter?'

According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
