Indeed, curvatures are associated with the forces of nature. I am trying to find this answer since long. Thank you.

Right.
So nothing can accelerate beyond the speed of light....except this magical box.
Makes perfect sense.

What a way of explaining...what lead Eistein to think...
Thank you for making science frame work so easy...starting from basic..

If you move up then what's below you becomes down but when you add time down becomes away which is behind so it makes sense that space must be curved.

Can you accelerate faster in less gravity?

We experience space time relative to the earth as embodiment of it's mass, would we experience the same as in distance, in less gravity? Or is distance relative to perspective?

Wait, if the box was accelerated away from earth at the same speed with rockets, it would be seen curving to the stationary observer in the opposite direction, but not due to warping/curving of space. Does that get me a Nobel Prize?

Yes, light falls in the same way of any object with mass. This is the best explanation of the Equivalence Principle I’ve ever seen.❤❤❤ Also, from the perspective of the falling person, the gravity field of Earth still exists, but the space is accelerating towards him, which distorts the space in the exactly opposite way of the gravity field.

Sorry, but that's wrong. It starts with Galileo's experiment from the leaning tower of pizza.

You've jumped multiple steps in Einsteins thinking.

I don't believe space is bent and I believe that people who believe space is bent are bent themselves. That's my comment and I am currently sticking to it.

Beams of photons bend around planets due to the interactions of the electrical and magnetic fields of the photons interacting with the magnetic field of atoms due to the moving electrons. Additionally, while not all matter is considered magnetic, all matter can be affected by magnetism for the same magnetic field reason.
