The fact that subatomic particles are popping into existence and out of existence all the time in empty space? Wouldn’t the temporary presence of untold numbers of particles exert some influence on expansion? I haven’t heard any documentary or publication talk about this idea. Is it dumb?
In: Physics
As anyone on Earth who has ever thrown something up in the air can verify, gravity tends to pull objects down/towards the nearest large source of mass.
If you add up all of the mass in the known universe, the pull of that mass/it’s gravity should be slowing down universal expansion. Basically the stars should be starting to slow down by this point, with an eventual goal of stopping, and starting to fall back towards the center of the universe.
Instead, everything we’re observing makes it seem like the rate of expansion is actually increasing (the starts are moving faster and faster away). With everything we can see, and everything we know about physics, we have no idea what is causing this increase. Basically the universe is behaving the exact opposite of how it should, based on our current understanding.
