My guess is that the expansion of space is due to there being a requirement for a net loss of information to drive entropy.

Fairly well. Your post suggests to me an experience with a hallucinogenic substance, but not an understanding of physics.

FFS.
Do you read anything you post?
That describes exactly what I said.
Get a clue, please.

I like that. What do the ripples represent? Dimensionality?

Quite possibly.
What's weird--- in my mind--- is the wave-like quality, suggesting a linear baseline... as though on a plate.

You could visualize it as a person holding a piece of taffy candy while walking. You pull the taffy apart say horizontally and squeeze it back together then pull it apart vertically and squeeze that back together. That is approximately what gravitational waves to to space, its a pulling apart and squeezing thing but a thousands of the width of a proton in amplitude which is why it took so long to detect after Weber made his first attempt with that 30 ton cylinder of aluminum covered with piezo electric detectors many moons ago.

LIGO's arms are way too short..should have been at least 10 miles each..then they would have proven G-waves much sooner.

you, the flat-earther with nothing but delusional beliefs and cannot handle eclipses, obviously cannot possibly have the slightest idea what you are taking about when talking about physics (or anything else science-related for that matter). Please spare us your unintelligent ignorant gibberish.

Rich.

Enlighten me: was that induction or deduction you used for such illuminating insight?

All well and good but it cost over 1 billion dollars as it is including a 200 million dollar upgrade and further upgrades coming. Now they are designing one to be used in space where the distance between mirrors can be anything you have the recourses to use.
If they have powerful enough lasers and large enough mirrors they could be 100 kilometers apart or more.

My guess is time dilation. Wherever there is time dilation in which time passes slower, all matter moves toward it. This explains gravity (mass attracted to mass) but it may also apply to empty space and that is why I suspect time passes in the center of the universe faster than time passes at the outer reaches of the universe.
This conveniently explains the accelerated expansion much like the accelerated movement of mass toward a planet, moon or star.

all of what you suspect is totally unintelligent nonsense and only in part because there is no center of the universe.

I'm not saying there is, but...

if there was a center of the universe, then.....


where would it be?

I'm sure no analogy is perfect but I've always heard the expansion of the universe is kinda like a balloon or it's a good way to show kids anyway... Draw your galaxies on the surface of the balloon then blow it up and you see them moving away and the universe expanding outward. Of course this doesn't explain why?
