The answer is, that is not a physics question, that is a philosophy question. Just like the question, "why does a positive charge attract a negative charge" is a philosophy question.

Warped spacetime IS gravity.

The fact that the mass is gone that was warping spactime.

That is correct. The light leaving the gravity well of a star is red shifted. If the star is moving towards us then that red shifted light will be blue shifted. No, it is not false. Not sure what you are trying to say here. According to the bible light was not omnipresent, but since we are in the physics section I have no idea why this would come up in the discussion. This is incorrect. If photons were pure energy (whatever that could be) then they would have no other properties, such as spin, frequency and momentum.

Light leaving the earth is very slightly red shifted due to the gravity of earth.

You believe in the past mankind knew about DNA and gene editing. That is an absurdly far fetched idea!

I guess this is what the OP is talking about: https://www.nature.com/articles/s41467-019-08824-8

Huh? What in the world is 'natures full logic'?

It seems like you are purposely trying to misunderstand me.

They are not different forces. Just like electrostatic forces can be negative or positive, magnetic forces simply have a different sign for N and S.

No it's not. Please explain what you mean by that. My guess is that you mean the north end of the magnet is one force and the south end of the magnet is the other force. Is that what you are saying?

If I assume when you write the '2 off magnetic forces' you mean the north and south poles, then the answer is scientists do not think they are the same. That's why they have different names.

I wonder what that means. I would say the 2 sentences were unrelated, so there could be no coincidence. That's nice that something about this thread makes you feel important and worthwhile.

You should stop spreading false rumors.

No you don't, you believe it is real but I have no idea why.

No problem, I've enjoyed talking about it.

So you don't even know if it's true? Sounds like you are purposely spreading misinformation about a health issue. Why in the hell would you do that?

No that doesn't support and VAIDS is not real. Since it's an anti-vac site we can confidently say the interpretation is not correct.

Then I recommend that you drink more water.

I can't believe you think it would be so difficult. So I guess we will just have to disagree.

Then if they send a message saying 2-2=4 then we would deduce that their '-' sign is our '+' sign. It really would be relatively easy for us to communicate mathematical ideas. It certainly would take a long time especially if they are like 40 ly away but it would be amazing.

I of course said nothing of the sort. What I said is that faster than light travel can result in a violation of causality. It is a simple matter for you to google this idea to read for yourself why this is true. There is no need to argue with me about it because it is not my idea. This is the view of mainstream physics and a consequence of relativity. You can choose to not believe it if you like.

And when the warp bubble (or whatever) turns off then you have traveled faster than light so it is possible to violate causality, so the problem remains.

How could that be done?

I start from the premise that FTL propulsion is impossible. The first reason is relativity. The second more important reason is that FTL travel can violate causality. The universe is very stubborn about some things. For instance the universe will not allow you to know your absolute velocity. I think causality is another thing that the universe is stubborn about. I don't think any potential technology that could violate causality would actually work.
