This question already has an answer here:
Oke, so my mind is blown by Einsteins view on gravity, at least as far as I understand the basics and principles he based his views on.
One of the first things that struck me was that most of his equations were based on the fact the photons had no mass, something which is virtually impossible to verify experimentally and something I can not convince myself of.
Now he states that mass bends spacetime: in other words, objects can only move in straight paths, but because the "surface" of a path can be bent, the trajectory relative to the mass is bent. So as a reaction, I did the following thought experiment that would separate Newton from Einstein:
Image in space (completely empty) and two objects with mass M and m (whatever the values) placed from a distance R apart completely at rest. According to my interpretation of Einstein, nothing will happen because even if spacetime is bent they have no motion themselves. Our earth orbits the sun because it initially had a motion and is now travelling in an infinite straight line, which becomes an ellipse due to curvature. Newtons would of course state that in my thought experiment, the two masses would collide.
After I realized this, I started to question Einstein's view. Is my basic interpretation correct about Einstein, and how would you (expert/physics professor/lover) respond to this thought? I personally find it pretty confronting...
BTW I'm just a high school student, potentially going to Cambridge to study physical sciences...
