Is it heavy or is it light

Is it heavy or is it light

 

There are just three objects in the universe

 

one stationary point(object) called A and

 

two other objects called B and C moving

 

away in the same directions at the speed of

 

light minus 1 m/s with respect to A.

 

B and C with respect to A get very heavy due

 

to relativity since it is just travelling under

 

the speed of light.

 

Then point A pops out of existence. This then leave

 

B relative to C as stationary now since A does not exist.

 

So now B and C are very light and not heavy as before

 

due to the theory of relativity.

 

Thus CONTRADICTION.

 

Do you see how difficult in resolving this

 

light or heavy mass problem is! You need quantum

 

entanglement between object for this to work

 

or the theory of relativity is not valid.

 

For this problem to be valid you need an

 

invisible ether that everything to be relative

 

to it so that things can reference that one point

 

in space.

It's not really that complex.

 

Consider 3 friends who hang out together. 2 are fat, and 1 is skinny. The fat ones are always feeling down about themselves because they're comparing themselves to their slender friend. But one day, the thin person dies, and the fat people are left to compare themselves only to each other. Suddenly they don't feel so fat anymore. Even to the skinny person, there was no absolute standard as to what is the proper size.

Just a final point

 

If (B+C) move away from A at near

 

the speed of light then (B+C) get

 

heavy. But wait; it can also be viewed as

 

A moving away from (B+C) at near

 

the speed of light. So the question is

 

is A heavy or (B+C) heavy?

 

If there is an invisible connection between

 

A and (B+C), maybe it is the pull between

 

these two set of particle separating from

 

each other(like a stretching rubber band) thus

 

result in getting heavy. Could this be the

 

result of quantum entanglement?

 

Just having 3 object in the universe makes thing

 

tricky doesn't it; that's the problem with thought

 

experiments isn't it!

 

Thanks,

 

Designer.

There are no contradictions here and no problems at all figuring out what each observer would see.

 

B and C moving

away in the same directions at the speed of

 

light minus 1 m/s with respect to A.

B & C are moving away from A at the same velocity (speed and direction). B & C are at rest with respect to each other. There are no relativistic effects noted by B or C WRT C or B. The only relativistic effects they note are WRT A.

 

Then point A pops out of existence. This then leave

B relative to C as stationary now since A does not exist.

The statement is somewhat correct but the reasons given are completely wrong. B & C were always at rest WRT each other. That didn't change irrespective of any change in A. That A suddenly disappeared only means that B & C might have to figure out what all of that momentum and mass were converted to to make A go bye-bye.

BTW: You're confusing "heaviness" with "mass". They are related but not at all the same thing. Nothing in your gedankenexperiment "got heavier" at any time. More massive, more momentum? Yes. Heavier (more matter) - no.
