From which reference point did the big bang happen 13.7 billion years ago? And if space time is expanding then isn't the amount of time between now and the big bang increasing at an ever increasing rate?

A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.

So, from that guy's perspective we are living in one of his orgasms/orgies.

But the age of 13.7 billion is based on the assumption that space is expanding and time is not

So you want to know whose observations/findings Georges Lemaître based his calculations on? Or are you accepting Georges Lemaître as the reference point? How many sub-divisions and pre-references do you require before any question you ask is satisfied?

Hey, as long as it isn't cubic

So long as you never rotate the cube I'll be everyone's favorite man with an erection, solution to their problem, and God.

spacetime is much more curved than space, which is nearly flat

Spacetime does not actually curve. It's a general relativity meme that the old guard is having trouble letting go of

If space doesn't bend and curve then how to you explain why space why space looks all fucked up and distorted when we point telescopes at galaxies?

Looks fucked up and distorted compared to what? When you stand next to the galaxy?

The present moment, approximately.

You mean, "does time continue to pass"? Sure.

sure, let's go with that

I mean an acceleration in the way time moves forward. Just as the space between objects is increasing. The duration between events is as well.
And not in the traditional sense where b happened 1 second after a. From the reference point of today that may be true. But from a further reference point where time has sufficiently expanded, b could be said to have taken place 2 seconds after a. So depending on your reference point in terms of time, the time between two events could be different.

I know there is a tendency to think of time as a derivative of entropy. But that's nonsense. time is an absolute. Spacetime is able to exist without matter and energy but matter and energy cannot exist without spacetime.

Also i believe time has more than one dimension
