Duke Wellington Posted August 16, 2022 #1 Share Posted August 16, 2022 There are four known forces of nature. Weak Force: Allows sub atomic particles to switch into being other types of sub atomic particles. Strong Force: Allows sub atomic particles to bond together. Electromagnetism: Electric and magnetic fields, caused by electrons. Gravity: The most controversial one as there is no evidence its a force. General Relativity says its the curvature of space-time, quantum theory wants it to be a force caused by a graviton particle. So the aim of a Unified Field Theory is to find out how they all unite into one super force that would have existed very early in the universes life. We can unify the Weak, Strong, and Electromagnetic forces with each other, but not gravity. Or we can unify gravity with electromagnetism in 5 dimensional space called Kaluza-Klein space, but not with the weak or strong force. Good so far? I`ll get straight to the point. Put a spaceship in a very strong EM field. So strong that gravity and EM unify (making them the same force). The crafty thing about EM fields is we can charge up a super conductor and they dont have any resistance. So we could spend a decade charging the ship up, and voila! Off we go with a warp drive. 1 1 Link to comment Share on other sites More sharing options...
Guyver Posted August 16, 2022 #2 Share Posted August 16, 2022 (edited) I’m not sure you connected the dots with warp drive there. True, intense gravity like that of a black hole and does warp spacetime, but has it been shown that gravity and EM even could unify? I wouldn’t think so based on what you stated in the OP. Although, I thought the graviton had been confirmed by experiment some years ago? Edited August 16, 2022 by Guyver Link to comment Share on other sites More sharing options...

The graviton is not a part of the nucleus, like you suggest. It's a photon/radiation like particle, that travels at the speed of light, and is generated by high power collisions, like the merging of stars or black holes. It's what likely causes gravitational waves. If it exists. We can't directly measure gravitational interactions.

Although, I thought the graviton had been confirmed by experiment some years ago? Gravity and EM can be unified together without the other 2 included, its called Kaluza-Klein space. If you imagine going from a football down to an atom (a billionth of a football). Then do it again, and again, and again, and again, and again, then you are down to the plank length. Gravitons are predicted to exist down there. 1 x 10 to the minus 54. Thats so far beyond our atom smasher technology it might well take 500 years before we come up with something to detect a graviton. All we know at this stage (assuming they exist) is they will have a right handed spin of 1. That means both anti-gravitons and gravitons can only attract.

Levels of energy needed are ginormous: Quote electroweak unification occurs at around 100 GeV, grand unification is predicted to occur at 1016 GeV, and unification of the GUT force with gravity is expected at the Planck energy, roughly 1019 GeV. (link, bolding mine) Before you reach 1028 eV, your spaceship would go through stages being liquid, vapour, plasma, atoms ripped appart, proton decay, quark-gluon plasma... 2 1 Link to comment Share on other sites More sharing options...

You had that in the next step: quark-gluon plasma (It takes a lot more energy to break the strong force than the EM, so there has to be two steps.) 1 Link to comment Share on other sites More sharing options...

Technically the bubble only needs to be one planck unit thick, and it goes around the ship. Edited August 17, 2022 by Cookie Monster Link to comment Share on other sites More sharing options...

OK, I'll omit constants/conversion units (won't change general idea). Energy density ~ T4 (T - temperature). T ~ 1032 K (1028 eV), hence energy density ~ 10128 J/m3. Your bubble, say, has radius of 100 meters and thickness 10-35 m, hence volume of your bubble shell ~ 10-31 m3. Thus energy (energy density * volume) ~ 1097 J. If I made mistake, say, on the order of 1030 J (1067 J instead of 1097), still unimaginably huge number. Link to comment Share on other sites More sharing options...

Also why does it need to fill the volume of the bubble shell? Can we not just have a very thin bubble wall where the energy is? Link to comment Share on other sites More sharing options...

Can we not just have a very thin bubble wall where the energy is? Thats what 'shell' means in my post, and thats why volume is so tiny, i.e. 10-31 m3; with 10 meter sized bubble, its 10-33 m3. 1 Link to comment Share on other sites More sharing options...
