With science fiction of the past becoming reality, and current science fiction becoming a reality slowly as well, here is something that I was wondering if it would ever be possible: anti-gravity.

Will we ever have anti-gravity vehicles like in such films as Star Wars? Yes, I know it's not possible in this day and age, unless you count magnetically levitated trains.

How can we achieve anti-gravity right here on Earth? Maybe it could be done by considering the Earth's mass.

Correct me if I'm wrong, but Earth's mass is 5.9736 × 1024 kg, so what is we had somehow develped a completely new type of metal, that's as strong as steel, but has the mass that is less than that of Earth? Wouldn't that mean that if we made a vehicle out of those types of materials, it would be like a leaf that is falling from the tree. Because of the leaf's light weight, it simply glides through the air until it reaches the surface. But what if we had constructed a vehicle that weighs less that a leaf, less that anything known on Earth, would that have the characteristics of negative mass? Or would it need to somehow have a greater mass than Earth?

What I have just said above doesn't quite make sense to some people. That's because everything on Earth has the mass which is less than Earth (obviously), but it's just a mind puzzling thing to think of. How, and if ever, will anti-gravity will be developed?

Yes, but not for the general public for at least a few decades. As for how, well im not a scientist and I'm tired, so I reject your reality and subistute my own. Yeah that made total sense!

I think he is confusing mass with density. If something had a greater mass than earth, it would have a greater mass than earth, theres no negative mass, thats were Density comes in.

hahaha yeah, I was thinking that if there was a metal that had a mass greater than that of Earth, on Earth, we would be in serious trouble :lol:

Anti-Gravity... as in the ability to nullify the effects of gravity on a massive body, is unlikely to EVER be developed. Does that mean we won't have "hover" technology using other technologies to overcome gravity, much as an airplane does?... Who knows?

Doesn't matter how light you make something. It still has mass and will always be affected by gravity. The best we can do is devise a system to overcome gravity rather than eliminate it. For instance, did you know scientists levitated a mouse using a magnetic field?

though not theoretically impossible if we are able to implement full higgs shielding. but ofcourse we've yet to find the elusive particle to conduct the research necessary to aquire any form of higgs shielding.

I guess dark energy, which is basically a hypothetical construct to explain the fact that galaxies are expanding away from the center of the universe faster than our current understanding of physics says they should be, could be credited with some sort of anti-gravity, um...power or something. But we've yet to actually detect anything like that, much less collect some or use it for anything.

Far more likely would be a vertical take off / landing type craft, or even some sort of hovercraft, except with vastly more powerful engines that are much smaller than what we've got today.

As far as the whole leaf thing, no. I don't think you could make a vehicle that's strong as steel and yet weighs as little as a leaf. Unless you attached a great big hot air balloon to the top of it.

i assume you would have to have something with such a high negative charge, that is repels against the earth. i think ioit might be possible, seeing how gravity is one of the weakest forces in the universe

I've now rejected the leaf thing completely.

All my life I thought gravity was the strongest force in the universe, but then I learned more and more of magnetism.

One idea I had for creating anti-gravity on Earth was to artificially manipulate it's magnetic field so that vehicles with an opposite charge could levitate on it. However, I began to reject such an idea out of fear that artificially toying with Earth's magnetic field would destroy the planet.

Very good point there about dark energy. Let's assume that luminous energy is dark energy's opposite. There's so much luminous energy at the center of the universe, with so much dark energy among the different galaxies, stars, planets, etc. that the 2 forces are repelling each other.

When you think about it, if dark energy isn't the force that would levitate "anti-gravity" vehicles, maybe it would be a field of luminous energy repelled against our own dark energy.

Or is dark matter the opposite of dark energy?

If you did that, you'd remove the quality of mass from everything "shielded" from the Higgs Mechanism... I don't think that would end well.

What I have just said above doesn't quite make sense to some people. That's because everything on Earth has the mass which is less than Earth (obviously), but it's just a mind puzzling thing to think of. How, and if ever, will anti-gravity will be developed?

Anti-Gravity... as in the ability to nullify the effects of gravity on a massive body,is unlikely to EVER be developed. Does that mean we won't have "hover" technology using other technologies to overcome gravity, much as an airplane does?... Who knows?

You shouldn't say that. At any point in time our view of the future is limited by what we know. There were scientists by the end of the 19th century that said there was nothing else to discover, as in real scientists not common people. Anti-gravity may seem absurd but if we were to travel 200 years in past, everything we have today seemed impossible even for scientists. Eventually, some major breakthrough may come along and a whole new branch of discoveries is uncovered.

Hell, even things like time-travel can't be 100% dismissed.

[QUOTE="Frame_Dragger"][QUOTE="TransformerRobo"]

With science fiction of the past becoming reality, and current science fiction becoming a reality slowly as well, here is something that I was wondering if it would ever be possible: anti-gravity.

Will we ever have anti-gravity vehicles like in such films as Star Wars? Yes, I know it's not possible in this day and age, unless you count magnetically levitated trains.

How can we achieve anti-gravity right here on Earth? Maybe it could be done by considering the Earth's mass.

Correct me if I'm wrong, but Earth's mass is 5.9736 × 1024 kg, so what is we had somehow develped a completely new type of metal, that's as strong as steel, but has the mass that is less than that of Earth? Wouldn't that mean that if we made a vehicle out of those types of materials, it would be like a leaf that is falling from the tree. Because of the leaf's light weight, it simply glides through the air until it reaches the surface. But what if we had constructed a vehicle that weighs less that a leaf, less that anything known on Earth, would that have the characteristics of negative mass? Or would it need to somehow have a greater mass than Earth?

All very good points. ^^

I tried moon boots myself. Not at all like what we saw in Arthur. :(

The more likely invention would be a focused point of artificial gravity. If you created an artificial point of gravity above a vehicle, it would negate the "real" gravity that the earth is creating, and cause you to float.

Some conspiracy theorists/science fiction scientists believe that is how aliens would power their flying saucers (also the reason for them being saucer shaped, so they can change direction easily by creating the artificial gravity in another spot).

I am not a physicist by any means, however if someone did manage to create some kind of anti-gravity device wouldn't it be immediatly my flung into space by the earths rotation?

You honestly think we should believe conspiracy theorists? Most of the ones I've seen are either crazy like Dick Cheny, or racist like Alex Jones.

An artificial focused point of gravity is much more likely than "anti" gravity, regardless of who "came up" with the idea. It's a brilliant concept.

Very well then.

Any other ideas on how to create artificial gravity? I'm no scientist (you already know that) but they say when things spin, science happens.

What would happen if we took a large, superconductor, under a city, and used it combined with a large, rotating electromagnet?

Are you high RIGHT NOW? Could you at least learn the difference between the four fundamental forces before spouting off like this... pretty please?

i assume you would have to have something with such a high negative charge, that is repels against the earth. i think ioit might be possible, seeing how gravity is one of the weakest forces in the universe

BossPerson
Unlike electromagnetism, the other macroscale force, it only operates in an attractive mode, however, meaning it is by far the domainant force in the large scale structure of the universe. You don't see EM forming black holes, for instance.

Yes, we know black holes have a whole lot of gravity, so much that even light itself can't get out.

And which way is Earth's electric charge, positive or negative? How would we be able to find out that property of the planet?

If an orbiter were to measure the electric field at every point in its orbit, we could interpolate a Gaussian surface and figure out backward from that the net electric charge of the planet.

The net charge of an object refers to electricity collected in it's material, right?

If so, are you saying something could levitate in or on top of static electricity?

The net charge refers to the sum of positive and negative charge; electricity is the flow of negatively charged electrons, so the two are pretty distinct.

Electric fields are static, produced by charges at relative rest, magnetic fields are dynamic, produced by charges at relative motion. Their effect on charges is also different, as electric fields are directly attractive or repulsive, where magnetic fields operate according to the right-hand rule.

Then how would you describe Earth's electric field? Or does each corner of this planet have it's own distinct electric field?

The electric field is a vector field and varies from one location to another. Edit: that's why I mentioned an orbiter needing to sample the electric field throughout its orbit; otherwise, a single geosynchronous reading would give all the data required.

Maybe when we find out what gravity actually is. Until then, we will have to achieve anti gravity by simply applying a force in the opposite direction.

Then the closest thing to hovercars we have is hovercraft. Then again, does a hovercraft really touch the ground very often, or does it only appear to be touching it?

No, none of us can predict the future. All we can do is assume where technology would go in the next 50 years or so based on scientific and technological development.

But yes, I'd like to talk to xaos more about physics. :)

I would strongly recommend www.physicsforums.com if you want to learn about physics, but be warned: READ THE RULES. PF is a place to learn about ESTABLISHED physics only, not anti-grav and the like. Still, you could get a fantastic education there if you wanted to. Beyond that, I'm always happy to chat about physics, but it requires the other end of the conversation be rooted in something like reality.

Some things that "break" the whole thing down: 1.) FTL travel: If we talk about wormholes or warp drives, etc... you have to understand that a round-trip Faster Than Light = TIME TRAVEL. You simply cannot avoid this, and so when we talk about one, we talk about the other. A vast amount of observation indicates that the arrow of time is a one-way street, at least for us and everything we see. 2.) Pseudoscience: This covers a lot of ground, but in this thread, "Luminous Energy" is a good example. Dark Matter may be any number of things, but it's still expected to be energy at its most basic level... just like everything else. Dark Energy may also be a number of "things", but would still be energy. That energy can take a number of forms and have many effects doesn't change that it's the most basic building block of the universe, along with spacetime. 3.) Asking WHY something is, instead of HOW it works. If you want to know about things that physics can't answer... metaphysics, religion, philosophy, etc are there for you. Physics can't tell you WHY light is constrained to an upper speed limit of 'c', only that it IS. ---- On the topic of this thread: anti-gravity = neutralizing gravity... this is NOT the same as overcoming gravity through magnetic levitation, which is like using The Bernoulli Effect to overcome gravity. One is a means of producing lift, the former is a means to actually adress how mass interacts with spacetime.

The reason I say that true anti-grav is unlikely to EVER be invented, is that you'd have to decouple mass from its effect on, and how it's effected by... spacetime. 2000+ years ago the Greeks had a better idea about the building blocks of matter than we do about how such a thing could ever be. Are all things possible? Sure..., but this is right up there with the chair you're sitting on turning into a dragon.
