Can you explain the validity of relativity theory? It seems to me to be untrue, as time is universal, and the time is now everywhere.

Here is Albert Einsteins’ thought experiment - if you can follow it through - you’ll be convinced…

That’s seemingly impossible - but it’s DEFINITELY true. The experiment has been repeated THOUSANDS of times (I even did it in a high school physics experiment) - and the answer is always the same.

They found a VERY strange thing about light. No matter where the light comes from - no matter whether the source of the light is coming towards you - or away from you. No matter how you’re moving towards or away from the light source…THE SPEED OF THE LIGHT YOU MEASURE NEVER CHANGES.

Why do certain religions consider menstruating women to be impure? Where did the concept of impurity stem from?

The point of all this is that from the result of an actual experiment - which has been repeated and confirmed literally THOUSANDS of times - a chain of logic and reasoning that can be explained in about a couple of pages - PROVES that time is NOT universal.

If that’s not...

And here is another…

What are good book recommendations? Does anyone know any YA books in general that has no romance? It is hard to find non-romantic books for teens nowadays.

Here is another version of that…
