Graduate Can a QM/GR overlap provide a breakthrough in understanding gravity?
A simple two dimensional representation would be to twist a stretched rubber membrane to create a stress. A clockwise twist might be labelled a positive charge and an anti-clockwise one would be a negative charge. If locked in some way, this would be like the stored energy in the twisted ropes...- Ran out of sp

Graduate Can a QM/GR overlap provide a breakthrough in understanding gravity?
There is a basic mis-match in the way GR and QM picture space. In GR, space bends to produce mass and gravity. In QM, space is a nuetral background for the actions of particles and force fields. Most recent work attempts to extend the QM/QED/QCD model to explain gravity. The opposite approach...- Ran out of sp

Graduate Is the concept of a point particle in quantum mechanics ultimately untenable?
Oh dear, I have unwittingly set up a straw man, based on oversimplefied summaries. I suppose the same arguments apply to black holes. It is often stated that matter within a black hole will collapse to a single point. If your basic unit of measurement is a parsec, the size of a black hole is...- Ran out of sp

Dr Lots-o'watts, Thamk you for getting back to me. I don't see any major disagreement between us. Zapper Z, Thank you too for your contribution. dxun, Again, thank you for replying. Personally, I remain to be convinced by string theories but I'm prepared to wait and see. But I'm...- Ran out of sp

Thank you for replying, Dr Lots-o'watts. Taking your points in order, 1. 'Common sense' is a conventional description which is often hard to distinguish from common ignorance. What I meant by 'nonsensical' is that at the limit of dimensionless particles the theory becomes strained and...- Ran out of sp

Graduate Is the concept of a point particle in quantum mechanics ultimately untenable?
Quantum mechanics is a very powerful and accurate method of describing the actions of small particles in space but it has its limits. On the large scale, QM cannot explain relativistic effects. On the smallest of scales, the theory starts to become nonsensical. QM is based on events whch are...- Ran out of sp
