SUMMARY

The forum discussion centers on the existence of extra dimensions, with participants debating the validity of string theory and its implications. One user asserts that while string theory suggests up to 11 dimensions, it lacks empirical evidence and remains untestable. Another user emphasizes that warping in spacetime, as described by general relativity, is a well-established concept, while cautioning against conflating quantum mechanics with higher dimensions. The conversation highlights the ongoing pursuit of understanding in theoretical physics, particularly regarding the nature of the universe and the potential for higher dimensions.

PREREQUISITES
  • Understanding of string theory and its implications for extra dimensions.
  • Familiarity with general relativity and the concept of wormholes.
  • Basic knowledge of quantum mechanics and particle behavior.
  • Awareness of current scientific debates surrounding empirical evidence in theoretical physics.
NEXT STEPS
  • Research the latest developments in string theory and its experimental challenges.
  • Explore general relativity and its solutions related to wormholes and spacetime warping.
  • Investigate quantum mechanics and its implications for particle behavior and existence.
  • Read about empirical tests for extra dimensions, including studies on black holes and light bending.
USEFUL FOR

This discussion is beneficial for theoretical physicists, students of physics, and anyone interested in the complexities of higher dimensions and the interplay between quantum mechanics and general relativity.

Other dimensions have been proven...

Since other dimensions have been proven both mathmatically and at cern, I do not consider the topic of warping out of our current space/time dimension out of the realm of possibility especially if it is done on an atomic or quantum level initially. A carrier particle that is labeled perhaps with an isoptope? Particles do seeth in and out of existence. Then if space/time is moving/expanding where would the particle end up. The rate of expansion of the universe perhaps? Thoughts on the subject...

Interesting thought but I am not sure what you're trying to discuss here. Is it the rate of expansion of the universe , the particle or energy fluctuations ?
I thought space-time was dependent on reference frames so perhaps the same applies .

They have not, and furthermore have received exactly zero experimental EVIDENCE, let alone proof.

In light of this, everything else in your post is nonsense.
 


String theory has proven 11 dimensions or at least 10 depending on which version of the theory you ascribe to. Did I miss some new revalation that contradicts this? I think it is pretty well accepted there are more dimensions than the 3 (or 4 if you include time)dimensional world we live in.

Please leave the personal attacks out. Nonsense is a little harsh. I’m in the pursuit of knowledge and intellectual discussion just like everyone else here in the forum.
 


String theory is, as of right now, a completely untestable hypothesis, which besides having exactly zero empirical evidence for it, also makes zero falsifiable predictions. It is by no means 'pretty well accepted' that the extra dimensions it predicts actually exist. Theorists find a rich playground in string theory, and to be sure it shows a lot of promise to be a theory which could describe nature. But again I have to reiterate, there is not a shred of evidence either for or against the theory. Science popularizers like to make it sound like it's inevitably true, but this simply isn't the case.

I will try to address the rest of your post a little more seriously:

Warping in spacetime is a common thing, and is the foundation of general relativity. There exist solutions which connect two apparently distant parts of the same universe via a tunnel, i.e. a wormhole. These are more or less classical objects, and while we don't know whether or not they do (or can) exist, at least they are founded in a well tested theory. It's important to note though that while it might seem, if you try to visualize this, that the wormhole has to somehow take a path through the 'fifth dimension', this is not the case.

Regarding warping on a quantum/atomic level, I have no idea what you mean.

I understand the idea you're trying to convey with a carrier particle, but any speculation here is science fiction.

The particles 'seething in and out of existence' is a result of quantum mechanics, and doesn't really have anything to do with other dimensions. It's not as though they are popping into our dimension from another, then leaving. Rather, they are being quite literally 'pulled' out of the vacuum.

Your last two sentences remain a mystery to me as well; I do not know what you're asking.
 


There is a shred of evidence actually:


http://phys.org/news/2010-11-black-hole-proof-extra-dimensions.html

Light bending by a black hole may offer proof of extra dimensions November 18, 2010 (PhysOrg.com) -- Researchers at the University of Pennsylvania report that a new test for measuring the ability of gravity to bend light seen from distant stars around large objects like black holes may offer proof of the existence of extra dimensions in the universe.

If you would actually read the paper here, you would note that nothing has actually been done. He is reporting on the POSSIBILITY of a deviation from GR, and how it COULD be measured. However he even states that this is likely to be beyond astronomical imaging capabilities.

This article is written pretty poorly though, since at first glance it does convey the sense that the proposed experiment has actually been performed. Since these kind of papers are published every day, it's pretty mundane though and I sympathize with the need to make it a little 'spicier'.

I did read the paper. Thanks for insulting me however with the presumption that I didn't.

Please mellow the attitude. Folks are trying to help you with your misunderstandings, and are trying to do it in a straightforward way.

No, nonsense is just right. That is NOT any kind of attack and your persistent belief that folks here pointing out where you are wrong is some kind of attack on you is not going to get you anywhere. Nonsense is nonsense and will be called that on this forum, without any intent to "attack" anyone.

+1 on what berkeman said

No attitude. Just don't do well with disrespectfulness. Nabeshin can continue to insult me since I'm the new guy. I'm sorry,

This post IS attitude. You are not being picked on. Go search the forum and you will see plenty of other posts, even from me, where others have been told their posts are nonsense. It isn't personal, it's simply the truth.

If you posted a paper/link to try and prove a point, and someone told you to actually read it when you had actually read it, how would you react Drakkith?

This discussion has gotten pretty far off topic. If you feel you've been wronged or insulted, then I suppose I'm sorry for the miscommunication.

Regardless, have I answered your original question to your satisfaction or do you have any other follow up questions about my responses?

No, thanks for your attempt to answer. Not sure we will ever be able to directly prove higher dimensions or dark matter from our space/time reality, but that doesn't mean that don't exist or we cannot hypothesis about the topic. I stand corrected with other dimensions being proven. I had thought string theory had the math to back it up, and that explained why gravity is weaker than the other forces due to dilution through the dimensions. I have a lot to learn I guess. Thanks for your time and thoughts.
