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

The quantum world is notoriously weird. Single particles can be in two places at once, for example. Only by making an observation do we force it to 'choose'. Before an observation we can only assign probabilities to the likely outcomes.

Such a picture cannot be reconciled with a smooth, continuous fabric of space-time. According to Einstein, space-time is warped by matter and energy, but quantum physics says matter and energy exist in multiple states simultaneously — they can be both here and over there.

According to Einstein, space-time is like a stage that remains in place whether actors are treading its boards or not —even if there were no stars or planets dancing around, space-time would still be there. However, physicists Laurent Freidel, Robert Leigh, and Djordje Minic think...space-time doesn't exist independently of the objects in it. Space-time is defined by the way objects interact. That would make space-time an artifact of the quantum world itself, not something to be combined with it.

The attraction of this theory — called modular space-time — is that it might help solve another long-standing problem in theoretical physics regarding something called locality, and a notorious phenomenon in quantum physics called entanglement. Physicists can set up a situation whereby they bring two particles together and link their quantum properties. They then separate them by a large distance and find they are still linked. Change the properties of one and the other will change instantly, as if information has traveled from one to the other faster than the speed of light in direct violation of relativity.

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.

So we have to leave a space of six feet for how long?

Why are we allowed to question einstein but not global warming?

Global Warming is settled Communism.

So, Space-Time doesn’t exist until you look at it.............................

Maybe the brainiac astrophysicists can solve our communism infestation here on earth first?

“Space-time is defined by the way objects interact.”

If something did not, does not, and will not interact with anything else, in what practical sense does it exist at all, from the perspective of anything else? Interaction defines existence.

As long as you have quantum separation, you’re good.

Old research - and yes, maybe 'players effect the game'... our thoughts change reality .

Because Einstein's theories aren't related to potential trillion dollar windfalls for academic frauds, global leftist bureaucrats, and s***hole kleptocracies.

Personally, I think we are just scratching the surface on a real understanding of quantum physics.

Everybody knows that space is filled with aether, which is the medium upon which magnetic radio waves, x-rays, and light travel.

I know because read about it in my 1040’s Radio Theory book.

Either something is measurable, repeatable, and testable or it’s B.S. unless it’s a guess at something that happened previously (creationism, evolution, continental drift).

But only that which can be measured matters IMHO.

“Personally, I think we are just scratching the surface on a real understanding of quantum physics.”

What occurs to me is that they will chase this (and perhaps already have) to the point where it is impossible for a human to imagine the constructs.

I somewhat followed the article but I have only a casual interest and have not studied physics in depth for many years. I actually don’t think it is possible for humans to really understand how the universe works. But I salute them for trying and nibbling at the edges of understanding.

They had radio theory back in the 11th century?

And I thought my 1985 AARL ‘Antenna theory’ book was old!!!

:-)

Does that mean the UFO aliens could be real?

Was 1040’s supposed to be 1940’s? The aether was pretty much discarded by the 1940’s, it is not necessary and does not add anything. Basically, the “aether” was the coordinate system in which Maxwell’s equations applied. Einstein “simplified” things by saying they apply in any inertial coordinate frame, but never managed to specify what an inertial coordinate frame is, though on timescales of nanoseconds over distances of a few meters, the surface of the earth is a good approximation.
