Was Einstein wrong? Why some astrophysicists are questioning the theory of space-time

I certainly hope not.

We’ve got enough problems already.

Either something is measurable, repeatable, and testable or it’s B.S

Nothing can be measured perfectly, and therefore no experiment is perfectly repeatable, except within the limits of experimental error. Sometimes experiments, or tests, only produce meaningful results as the average of many trials.

Was 1040’s supposed to be 1940’s?

Yes. [Lowers head sheepishly in shame...]

We can not even understand infinity or gravity yet we know it exist.

[Reeses]

Theories are simplifications, and any simplification of the real world is at best an approximation. So all theories are wrong, but a very small number are useful. The usual proof a new theory is useful is when it results in a new way to kill.

"Modular space-time theory can accommodate such behavior by redefining what it means to be separated. If space-time emerges from the quantum world, then being closer in a quantum sense is more fundamental than being close in a physical sense."

That's what she said.

Interaction precedes existence?

Have you just created a new philosophy: Interactionism?

from Wikipedia:

“At present, gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass... However, for most applications, gravity is well approximated by Newton’s law of universal gravitation, which describes gravity as a force causing any two bodies to be attracted toward each other, with magnitude proportional to the product of their masses and inversely proportional to the square of the distance between them.”

MASA consulted Newton’s version to get to the moon.

We don’t know that infinity exists. It might exist as a mathematical concept, but even that is dicey. There is no evidence yet, or could ever be, that there is an infinite amount of space, time, matter, or energy.

we are just scratching the surface on a real understanding of quantum physics

Agreed.

The history of science is kinda clear on this point--often the "old science" is not "wrong", it is just incomplete.

We don't know what we don't know.

[Seruzawa]

Listening to physicists these days is similar to visiting a mental institution. Except that the inmates of the institutions generally make more sense.

This theory could be an explanation of how God could be both Divinely Simple with no parts or extension, and omnipresent, i.e. everywhere.

If God is entangled in all of creation, and being close is more a quantum than spatiotemporal phenomenon, then God can be everywhere without being anywhere.

You really do not want to go there...most of science gets flushed down the toilet kinda fast:

The link is Rupert Sheldrake's banned Ted Talk "The Science Delusion" where he talks (among other things) about scientific "laws" that have a nasty habit of changing over time and scientific "constants" that turn out not to be constant.

I can't really measure why I like bacon much more than broccoli, but I know that I do and that matters a lot to me.

If I ever ordered a bacon cheeseburger and found that it had broccoli in it where the bacon ought to be I would be sorely disappointed.

[RedStateRocker]

Yes, of course. But within parameters testability is key. If I transmit a radio signal on 451.8625 MHz, it won’t be *exactly* that frequency, but close enough to test and measure in a repeatable fashion.

[enumerated]

Thus the age-old question: Does a tree falling in the forest make a sound if there is no ear to hear it?

[Petrosius]

We don’t know that infinity exists. It might exist as a mathematical concept, but even that is dicey. There is no evidence yet, or could ever be, that there is an infinite amount of space, time, matter, or energy.

What are you talking about? We all know that Congress has an infinite amount of money to spend.

[RedStateRocker]

It’s hardly “banned” LOL.
