void or weakening dark energy
does the implication of either of these two theories which explain the findings of the desi data not rule out any possibility we are in a metastable vacuum? if either of these are true our calculations on the cosmological constant are wrong and we are most likely in a stable vacuum.

>light passes through void
Hmmmmmmm.

the theory is our galaxy might be in a void of less dark energy compared to the surroundings so thats why the constant is off

We simply don't know enough about physics yet to make predictions about the state and composition of the entire universe

we know enough to know the standard model is flawed as it breaks down at high energy

Can someone explain:
If we are moving in the universe around 600km/s which would be 0.2% the speed of light, we can only increase the speed the other 99.8%?

Relative to what?
Here's no such thing as absolute speed, all speed is measured by comparing to something else. Except for c. C is an absolute speed, and ALL observers measure the same c. If you're moving at 99% c compared to the sun, light still moves at c from your perspective.
Doesn't make any sense? That is what relativity is there for, turns out time and space act fucking weird at these speeds to ensure that NOTHING with mass ever reaches c.

So the speed of light is relative to what?
So it's possible that something that looks like light to us is could be matter to someone else?
Sorry if I look dumb.

The speed of light is absolute. Anything moving at light speed moves at the same speed in ALL reference frames
Nothing with mass can reach the speed of light, only massless particles

So what happens is that close to the speed of light space bends in a way that every reference point is the same or something like that?
only those outside of the speed of light know the direction and source of that light?

If you take the math at face value, when you move at the speed of light time stops for you, and distances become 0. You arrive anywhere instantly
We don take the math at face value though, we just say that the equations are not solvable for a speed of light reference frame

ummm, but soientists says "energy" is real, god is fake, the universe WILL end at heat death, and NOTHING will come after it, even though there shouldn't have been any energy before the existence of the universe by their logic doe?????
