"Density of spacetime" is in quotes.. I wouldn't know how different to call it. Maybe different excitation of a field that gives particles a mass. I am not a physicist.

Again, I was not asking about 12 inches in a foot. But why is the value what it is and could it be something behind the value, something that determines our measurement of it, something that causes light to have that speed? It would be the same as I asked why the speed of light is not twice...

Quite contrary .. I would still get that the same mass still has the same force of gravity I guess... but the same number of particles would have different mass and gravity. So the star of the same size would be with different gravity. What I am trying to ask is is there a possibility that...

Is it so? If we lower the speed of light then recalculate all so fine structure constant doesn’t change and then calculate the Earth's (or any same number of atoms) gravity and mass?

Please correct me if I am wrong fine-structure constant can be 1/137 even if c has a different value it only means that e would also need a different value and so on.. which is my point exactly :D (π can stay the same I guess)

Yes exactly my question was is it invariant, sorry.

Yes, the number is the choice of units but you haven't understood me. I am not asking why is the choice of units what it is, but why the value is. Why the value is not 5% more or less for example. Could it be that it's not the constant and that it does depend on some other property?

Well not exactly. Maybe measurement depends on something we still don't understand. What if there is something that determines the speed of the massless particles. And what if that is a different value across the galaxy for example (also across the vastness of space of course). IDK, for me, it...

Well E&M is also what we measure here. It has constants as well. Measurement wouldn't be the same here and closer to the center of the galaxy if there is something we don't understand about spacetime that causes the galaxy to rotate the way it does and if there is no dark matter.

I was just watching too many YouTube videos, thinking what if there is no such thing as the Dark Matter but something we don't understand about gravity and spacetime. In that case speed of light probably would depend on where in a Galaxy you are. Closer to the center it wouldn't be the same also...

The question is of what does it depend on? We take it for a constant still how do we know that its the exactly the same as in a vacuum in a center or closer to the center of our galaxy for example. Why is the number what it is?
