How can you believe in Einstein's Theory of Relativity when it contradicts basic common sense,
Most of advanced physics contradicts "common sense".
Our common sense evolved to avoid being eaten by lions in Africa. Not to understand quantum mechanics or to have an intuitive sense of what it is like to travel at extreme speeds or be in the proximity of extreme gravity.
Almost every discovery of advanced physics has defied our "common sense".
and fundamental laws of Physics?
What laws are supposedly contradicted by relativity?
Are you aware that without accounting for relativistic effects, something like GPS for example doesn't work?
Do you know and understand why that is the case?
For instance the speed of light is a constant, so how can photons experience no time or distance? How can something just happen and yet supposedly happen at a different time for someone else? How can two twins ages change just because of travel?
It's explained in the theory of relativity why....
To me these are ridiculous ideas.
Which only speaks to how your mind works, not how reality works.
The facts are the facts and they are undeniable.
Take two atomic clocks, the most accurate you can find and synchronize them.
Send one into orbit around earth at 40.000 km/h and keep the other on the ground.
Then have the space probe land on earth again some time later.
Compare both clocks. You will see they no longer show the same time.
This is the principle that must be accounted for to make GPS work. GPS pinpoints your position by measuring the time it takes to exchange signals between a receiver on earth and the satellite in space. This comparison is done by having the time tick of the receiver on the ground and compare it to the time tick of the clock inside the satellite. If the relativistic effects aren't accounted for, then the measurement is off. Then the system will fail to pinpoint your position and it will have a margin of error of several
miles. So, the clock inside the satellite is thus calibrated to tick at a
different rate as opposed to those on earth to account for the relativistic effects of traveling in orbit at 40.000 km/h. Do that, and then the error margin of pinpointing the position of the receiver is suddenly reduced to 1 or 2 meters only.
And that's just one way of MANY how it can be demonstrated that time is relative to the observer.
There's plenty of other experiments you can do to demonstrate the same. And the measurements of the experiments will ALWAYS match the relativity equations to a T.
