These days I am watching YouTube videos on spacetime, relativity theory, cosmology in the field of theoretical physics. Probably, Einstein was the first person to find some kind of relation between space and time. He said that space and time are not separated but interlinked. These kind of theory cannot be proposed just by thinking, it is largely based on the perception. He had special ability to precept and visualize what happens when an object moves very fast. By "very fast" I mean objects moving close to the speed of light. He postulated that speed of light is constant in any frame of reference. (non-inertial?) and nothing can move faster than speed of light. Secondly the laws of nature are same in any inertial frame of reference. Basically it says that an object at rest or moving at constant speed is same phenomena as far as laws of physics are concerned. These are outcome of special theory of relativity. Further general theory of relativity reveals about the curvature of space and time due to gravity/mass, blackholes, warmholes, timetravel etc.
I feel that after Einstein died his theory couldn't go to next level. Newtonian mechanics remained un-questioned for approx. 300 years. Meanwhile quantum mechanics came and the whole world drifted towards it because it somehow predicts the position of electrons quite accurately that is good enough for industrial applications. I feel that quantum mechanics is not a complete theory but an approximation theory. However, no body knows that it has to be non-approximation theory. I personally find relativity more interesting than quantum. I may be wrong but my prediction is relativity only will unlock the door to the final theory if at all it exists. Ultimate theory should also describe human consciousness which is neither electron, proton or neutron. Human consciousness is wave or particle? I haven been contemplating on this and looks like it is neither wave nor particle it's something else. And probably it travels faster than light also.
One very basic phenomena scientist has to understand how to travel from point A to point B. Although the problem looks very simple but actually this is one of the most mis-understood problem. Let say A......C.......B is the path from point A to point B via point C. To go from A to B why I always have to go through C. Why cant i just hop from A to B directly, skipping C. According to Einstein if you travel from A to B via C then it is limited by speed of light. But is it not possible to avoid travelling A->C->B therefore go A to B in 0 time, no matter how far A and B is separated. I am not denying Einstein's principle he is probably right when you travel. But if travelling itself can be avoided it will open another dimension. I think quantum mechanics predicts these kind of hopping and they call it teleporting/entangled-particles. Einstein said space and time is illusion and they always exist. If that is the case then travelling from A to B without C is possible in 0 time, at least theoretically.
