If the Grand Unified Theory proves to be true, would that mean that gravity could be theoretically created with electricity as in electromagnetism?
Maybe, but probably not. The idea of a single explanation of how two things are connected to each other doesn’t necessarily mean you could convert one into the other. For one thing, electrical charges can repel or attract but gravity only attracts.
I understand the relationship between bread and toast but that doesn’t give me the ability to turn toast into bread.
IANAP.
First you need to tell us (and perhaps the Nobel Committee) about this Grand Unified Theory you have discovered.
We manipulate electromagnetism by moving around charges. In the same way, we could manipulate gravity by moving around masses. It’s just that the necessary masses to do anything interesting are nontrivial to move around.
I’m not sure the purpose of your post but here is the GUT info:
And I never claimed to have discovered anything. Nor did I say it was confirmed, I said “if”. Read for comprehension.
What is this grand unified theory?
Also question
An electromagnetic field, strong enough to attract a human being and give them weight, would that not be a bit on the very unhealthy side?
And how would other things, electrical and electronic work in such a field?
Would it not just be easier to induce artificial gravity through centrifugal force?
Well in a space vehicle/station anyways, im not sure how to work that out well on a stationary thing like a base on a large asteroid etc.
Maybe i dont get what the OP is talking about?
It’s quite possible the OP doesn’t know what he’s talking about either. That’s why I posed the question.
The question occurred to me because (as I understand it) there are those that believe that once the GUT can be determined the next step would be the TOE, tying all of the forces together. A non-magnetized piece of metal can be made to be magnetic by applying electricity. From FactMonster:
“Each electron is surrounded by a force called an electric field. When an electron moves, it creates a second field—a magnetic field. When electrons are made to flow in a current through a conductor, such as a piece of metal or a coil of wire, the conductor becomes a temporary magnet—an electromagnet.”
So I wondered IF gravity is related to electromagnetism, could gravity also be manipulated by electricity. I’m not a scientist so this might be a silly question but that’s what this forum is for, right?
Wood, for all practical purposes is non magnetic.
Now, everything is made of atoms, protons neutrons and electrons
So given enough incentive, i guess you could say everything could be magnetic, and conductive so to speak.
Thing is, the amount of force (which probably is not the right word) you would have to apply to induce this would not be safe.
Lets take conductivity just cause it is simpler
A piece of copper can easily be induced to move electrons around, and it will happily move them around at a rate that would not hurt a fly.
But to get that wood to move electrons around (not just air gap over it), you would need an amount of power not safe to stand near.
So as for gravity via magnetism, since the wood is not normally magnetic, imagine what kind of field you would need for it to be so.
How safe is that kind of field going to be for a living human being?
We are not magnetic per se, but more so than a piece of wood, and we are electrically operated beings, and things that are electrically operated do not seem to fair well when shoved in the mother of all magnetic fields.
I mean maybe i dont understand, i am no scientist, but you are talking about creating a field strong enough to induce me to polarize and be attracted to the GROUND side of the pole along with my chair and desk and pencil etc? yes?
I am thinking that would kill me?
If gravity was magnetism, i think we would all die.
Gravity is strong, but the earth’s (which is a big magnetic field generator) magnetic field is very weak.
Very very important yes and strong enough for what it does do, yes
But very weak all the same.
If it was on par with earths gravity, i dont think us as we exist now would live so well?
adding via edit
Gravity if i remember correctly equates to mass.
Mars has no magnetic field, it does have gravity though, because it has sufficient mass.
A block of wood the mass of earth would be non magnetic, but it would have plenty of gravity.
Indeed. No normal matter is completely non-conductive, just resistant to being conductive, which might mean it’s only conductive once because the process of dissociating electrons from their atoms ruins all the molecules in the substance and destroys the structural integrity.
The word you’re looking for is voltage, and it’s safe enough that you can char and destroy a piece of wood by forcing it to become a conductor without causing any degenerate matter to be created. 
No, because of my next point:
Gravity is tremendously weak. It only takes a few atoms’ worth of contact with the ground to keep you from falling into the Earth’s core, after all, and a completely safe bar magnet will make an iron nail leap into the air against gravity. Gravity is the weakest force* we have everyday experience with by an order of magnitude of orders of magnitude. (Electromagnetism is about 1E33 times stronger than gravity.)
*(If you mention that it isn’t a force I drop you into a pit, where you’ll learn about frame-dependence when you hit rock bottom.)
So. If we take magnetism to mean “what happens when electric charges accelerate”, then the gravitational analog to magnetism would be what happens when massive object accelerate. We know what happens in that scenario: Precisely diddly-squat, experimentally speaking, unless you have a truly mondo-huge uber-sensitive experiment like LIGO explicitly looking for gravitational waves. Gravity is weak.
Good enough operational definition if you’re in a Newtonian frame of mind.
Yes. It has nearly as much mass as Earth, and, therefore, nearly as much gravity.
Plenty? When’s the last time you fell towards a block of wood?
When’s the last time you were near a block of wood with the mass of the earth?
I’m assuming this is also a block of wood with a greater volume than the earth–if it had a comparable volume to an ordinary block of wood, then it would no longer be would, it would be some kind of degenerate matter that used to be wood.
Mars has about 10% of Earth’s mass and 37% of the surface gravity, which is quite a bit less.
On the scales we’re looking at, that counts as “nearly as much”. Mars’ gravity is close to Earth’s gravity in a way that gravity is not close to electromagnetism.
First point. As defined a Grand Unified Theory explains how the weak nuclear force, electromagnetism and the strong nuclear force are related. To include Gravity you want a Theory of Everything.
But let’s look at the one unifying theory we do have to give a starting point to answer the actual question in the OP. Electroweak interaction is the unification of the weak force and electromagnetism, but it doesn’t let us create one with the other, it just gives us a single theoretical framework for both and shows that the two forces are one and the same at sufficiently high energy levels.
We can assume the same will apply for a GUT or TOE as well, it will give a single theoretical framework and show what the conditions are where the forces merge, but that won’t mean we can create gravity through electromagnetism, unless we do so while at big bang level temperatures.
D’oh! OK, I glossed over that part entirely.
Right. But, of course, if you magically popped an Earth-mass block of wood into existence, it would immediately compress and heat up and most of the mass and volume would no longer be wood after a short period of time, but an equal-mass amount of whatever atoms the wood was composed of in some more compact configuration. A dirty, flawed diamond, because it has so much carbon? It would obviously be spherical, whatever it was.
It would never happen in reality, but it’s fun to think about.
Ok, humor me a minute
We take a very long piece of wood, we fix it in a way that it is insulated (i dunno, float it in space perhaps) so there is no possible route from + to - except through the wood.
And the wood is long enough to prevent the electricity from just jumping the air gap.
When you get enough voltage applied to one end of the wood to force it to conduct through itself to the other end.
This has not reached an inherently dangerous level?
I would not myself call gravity weak, even the small moon distorts and bulges the earth, the gravity of jupiter has an effect on other planets far from it.
The gravity of the sun itself has long reaching effects.
Different perhaps
magnetism also has dependencies that gravity does not seem to have?
A magnet can attract a nail, but not a piece of wood, or granite, or water, or carbon dioxide.
Gravity can attract all those and the magnet, and does not appear to be dependant on any particular activity of electrons.
And a ball of ice water or wood of sufficient mass would have gravity.
Not sure what frame to use?
Everything that has gravity has mass, a large-ish amount.
The more mass, the more gravity
the material composition can be totally dissimilar
Umm well…
Ok fine, barring the odd mishap? Admittedly never, BUT…
I have never run into a block of wood that was 5.972 × 10^24 kg either.
Substitute wood for lead rubber glass ice or a dense ball of hydrogen, same thing
A little magnet the size of your hand can’t do anything worth mentioning to wood, granite, water, or carbon dioxide. A laboratory magnet, however, can levitate wood or water, meaning that the magnet (weighing perhaps a ton or so) is producing a stronger force on the object than the entire Earth is, even for an object that we think of as nonmagnetic.
Perhaps, and yet it is gravity that makes the magnet weigh a ton and prevents the levitated object from just being ejected off into the ether.
But more importantly, If you take said magnet (assuming it can repel or attract a human), and stick a human being on it 24/7
how good is it for the human being?
And how would things like computers etc fair sitting on it?
Google levitating frog.
Did not find (yet) any talk of long term effects on froggy, let along an entire starship of humans living in it 24/7
Dangerous in what sense? To who? In the experiment you set up, the electricity isn’t going to hurt anyone, because it will be contained within the wood. If you were in the wood’s place, yes, you’d likely be killed by that same voltage, but that wasn’t the experiment you set up. If you were floating in the vacuum at some distance from the wood, you’d be perfectly fine.
Right. Gravity, unlike the strong force, is unlimited in extent. That doesn’t make it strong compared to the other forces, it just makes it far-reaching. If the planets and stars had net electrical charges on them, the forces associated with those charges would completely swamp gravity at any given distance: They’d both obey the same inverse square law, and the electromagnetic force is so strong to begin with it would remain stronger.
Not as different as you seem to imagine. The main difference between gravity and EM at large scales is that EM is usually neutral at large scales, with positives balancing negatives and resulting in zero net charge, whereas gravity is always attractive for any known substances. There’s no such thing as anti-gravity, so there’s never mutual repulsion, only mutual attraction.
Therefore, gravity is purely additive, so every gram of mass of the Earth is pulling you down. Yet you can still stand up by using only a trivial number of calories and muscles based on electromagnetic principles.
As Chronos said, this isn’t as absolute as you seem to imagine, but it does touch on points I made: Even though gravity has all the advantages here—it’s always attractive, it works equally well on everything, and everything contributes to it—it still loses to electromagnetism.
If you move from Newtonian gravity to General Relativity, you find that energy contributes to gravity as well, not just mass. But in everyday circumstances, you can handwave that away and pretend that gravity is purely proportional to the amount of mass.
