Is it still impossible to build an anti-gravity car that floats around mid-air like real vehicles?

Question

Are there any developments about anti gravitation force around?

A floating skate board? NO?

Answer 1

Yes, it's impossible. No, there aren't any "developments about anti gravitation force around."

The dream of anti-gravity is just an all too frequent delusion. It's like the search for "The Philospher's Stone."

We now know that the local gravitational acceleration tells us in what direction, and with what magnitude, the local rate of the running of time is changing most rapidly. The rate at which time proceeds anywhere is itself determined by the global solutions of the full equations of General Relativity, though those themselves can simplify in certain limiting cases such as weak-field, slow-moving Newtonian situations.

Any attempt to make an "anti-gravity device" will require some manipulation of how time runs locally, at least reversing its local gradient. The likelihood that such control over how time runs will ever be achieved by humans is so remote that this very observation seems to rule out the possibility entirely.

The notion of practical anti-gravity belongs at best in the "wishful thinking" category and at worst in the "crank mailbox."

I'm sorry, but that's the way it is.

Live long and prosper.

Answer 2

There are some developments regarding possible "anti-gravity". Here's a link to an article in Science Daily about that. We're still a long ways from any practical anti-gravity device, but at the same time, it's not proven that it's fundamentally impossible. As of right now, we still don't an unified theory of gravitation and other forces, so the picture is incomplete. We can't tell yet if anti-gravity is impossible.

Addendum: For those who think anti-gravity violates conservation of energy, how do magnets work, then?

Answer 3

There is nothing called an anti-gravitational force. All matter will exert an attraction force with each other. It is possible to create a force to counteract gravity, but to create an anti-gravity car is impossible.

Answer 4

ummm, are you severe ? cuz this feels like a shaggy dog tale. now and returned I nonetheless undecided while human beings are quite stupid, or in basic terms joking. there is not any distincion in gravity between macro and micro. The rules of gravity are the comparable for each merchandise. the factor is, that there are 2 distinctive rules. Newtons regulation become the 1st one, that's a less complicated form, and nonetheless used for uncomplicated initiatives. the different is Einsteins accepted relativity concept, which takes different aspects under consideration, like time. What ever formula you gonna use, it doe snot rely, while you're speaking with regard to the earth orbiting the solar, or human beings leaping interior the air. Its the comparable stress doing the comparable factor.

Answer 5

While it may become possible to manipulate gravity in some ways (a very unlikely may I should add), the sort of antigravity you suggest will always be impossible.

The reason is that it would violate the laws of conservation of energy and the laws of thermodynamics. Einstein was led to his theory of general relativity in part by a realisation that gravity must obey conservation of energy and so must apply to light as well as to matter.

Sorry to disappoint you.

Answer 6

Gravity permeates every thing,you can"t shield it or nullify in the sense that you could float a mass.
