Would a 5th Dimension Solve Quantum Gravity?

Meanwhile string theoriest vibing in 10 dimensions...

Time doesn't count as a spacial dimension. When people talk about "The 4th dimension" or "5 dimensions", we're talking about spacial dimensions, not time.

[JASONQUANTUM]

Fifth dimension is likely information. There is information contained within the geometry of spacetime. The information is the slope of a quantum state vector on a qubit.

[aresh]

I have a hypothesis about this: the 5th dimension isn't a small space dimension, but a very large time dimension, in which the full spread of probabilities is laid out

[garrett]

This is what ive been saying. Instead of making GR work on fields, make QM work on the background fabric of spacetime.

Well if gravity doesn't work on quantum scales, then it has to be an emergent property of the quantum. Suspect it's due to the speed of light/causality on the sides of massive objects facing each other interacting faster than the two sides of the massive objects facing away from each other.

The objects are essentially experiencing time/causality at different rates on the closest sides to each other vs the furthest sides from each other. As momentum has to be conserved on all sides of the objects, it translates in relativity as a warp of spacetime.

Relativity and gravity emerge from quantum interactions at a distance which become subject to the limit of C. You can see that playing out in the Roche limit where the difference in the speed of causality interactions throughout the object are so great that it rips the object apart.

On galactic scales the centre bulk of a galaxy experiences time faster than the spiral arms rotating where matter is less dense.

The 5th Dimension as a concept gained its greatest popularity during the late 1960s and early 1970s, after Kaluza-Klein first worked out its shape as being best visualized as “balloon-like”. The result was “Up, Up and Away” their biggest contribution to theoretical physics.

QED.

I think the geometric theory of gravity is too beautiful to be anything else. General relativity reduces to Newtonian gravity when you plug in the minkowski metric with small deviations of curvature. Too beautiful to be a coincidence. Quantum mechanics needs to define space-time first, GR doesn't need to change anything

[ThurVal]

In five Dimensions classical field equations occur. The only quantized entity (kleins idea) is charge. But the normal dimensions stay large. So, mechanical sizes remain unquantized.

4th dimesion itself need not be an appearance with objects such as a 4D cube (tesseract). There are some aspects such as gravitation, orbital path, quantum entanglement etc are falling in 4th dimension. 4D serves the background for 3D world. Moreover, without knowing how much a 4D can accomodate, people keep imagining 5, 6, 7...even 11, 26 dimensions by projecting the geometry of objects. There are only 4 dimensions to explain space-time where 4D is same as 0D same like 0 and 12 in a round clock. I have worked the theory of singularity more fundamental than relativity and quantum mechanics thus showing how it is connected without any contradictions to actually exist between them. "Fundamental theory of Singularity (FTS)". Book available in amazon online stores or browse the title...for your reference..thanks.

The literal fact that we can perceive the 4th, 3rd, 2nd, and 1st dimensions means we are 5D entities.

5D= consciousness.
4D= time.
3D= space.
2D= scale.
1D= particles.

[Kurtlane]

I wonder if we really need a physical dimension. Maybe it's an "imaginary" dimension, in the same sense in which there are imaginary numbers. At this point dimension becomes the same thing as symmetry, and we are off to the wonderful world of symmetries.

Von Neumann said something like "In physics, you don't demand that things make sense. You just get used to them not making sense."

[GyroSportFlying]

But surely we don't live in just one dimension of time? We each live in separate dimensions of time. It's a perspective thing?if you believe in 5 dimensions then you should easily believe in 6, 7 or 8 or Even more?

[AprilMarie-oysh]

How do we actually know we live in a four dimentional universe? Who measured how many dimensions there are? And how do you know if someone says that more than four is wrong? Explain.

[maofria]

So the idea of ​​tiny, "invisible" extra dimensions was proposed as early as the 1920s? I believed that string theorists were the ones who came up with this concept.

[glenmenas]

I don't understand the statement that time is a spacial dimension and that it's obvious. It's not obvious. Has that effectively been proven? Is time really just spacial displacement?

[SergenK]

i don't understand why people view time as a seperate dimension of space. einstein proved that time and space are the same thing thats why we call it spacetime. it is a spatial dimension that we cannot perceive as our length depth and width. only that there is time.

[GrapplingwithPhysics]

Couldn’t the fields of quantum field theory also be interpreted as extra dimensions?

[GyroSportFlying]

Can't we split time into 3 dimensions? Past Present and Future.

[nothingtosee]

Yeah, just keep adding dimensions until the math works.
