[@mahirbalayev5835]

​@@EugeneKhutoryansky but there's a possibility to create antigravity without violation of physics laws. For example, satellites around the earth. If they will increase their "horizontal" velocity above the first space speed they will change their orbit to upper orbit. Imagine that you have vehicle which's centre of mass is rotating with speed of more than 8km per second. Then it must fictive force which will push it up. And it will be antigravity. Thanks a lot for your attention and for your prompt response.

[@EugeneKhutoryansky]

Mahir, I don't think I understand what you are saying. I don't see why you think a rotating object would move itself to a higher orbit.

[@aliababwa3866]

who is this General Relativity and why haven't they been fired yet

[@52flyingbicycles]

Ok, but if I did an experiment within my box that determines there was a different rate of acceleration at different parts of the box, I would be 99.9% sure I was in a gravitational field because that is way more likely than a uniform gravitational field existing in the entire universe that cancels out the variation in gravity in just my little box.

[@EugeneKhutoryansky]

The uniform gravitational field throughout the entire would cancel out the gravity only at one specific point in your box. Even if you don't believe that such a uniform gravitational field exists throughout the Universe, the issue is that there is no experiment we could perform that would prove it, and this is what General Relativity states.

[@xhalexj]

And yet that supposition requires testing the entire universe to prove. Seeing as how it’s impossible to explore an infinite universe we would always be supposing rather than knowing about any of our scientific information. Unless some alien race whispered us all the secrets of the universe with certainty then we may never understand how to produce true antigravity

[@11Petrichor]

@@EugeneKhutoryansky Maybe if we use sensors to our sides that can measure their locations with respect to us in the center of the box. I'm thinking of geodesics, straight lines as we approach the surface of earth. But maybe the atmosphere inside the box would prevent movement of the sensors, so the box would have to be a vacuum, lol. We would suffocate, but we would have our answers:)

Inside the accelerating box, she feels the force of the box pushing at her feet, with each atom propagating that force to the atom above it in the direction of the force. If the box were an antigravity device, all atoms within the box accelerate at the same time, so there would be no force propagating from the floor upwards - the gravity outside has no impact inside, they are entirely different frames. The person inside would thing she is in constant free-fall no matter which direct a force was applied to the box. Outside of the box, people would see it move, but inside all motion is relative to the box only, which would seem like antigravity to her, because there is no way for her to tell the difference.

[@xhalexj]

But how does one affect gravity in only a small space without in turn affecting the surrounding space? Would that device need to generate a force that would act in agonist towards the gravitational field at all times? In that sense it’s not an “antigravity” device as much as it is an hot air balloon or blimp at that point, both of which require fuel to resist the force of gravity.

С момента разгона пучка протонов кривизна пространства вблизи пучка будет иметь одно направление, с момента торможения до момента остановки пучка протонов, кривизна пространства будет отрицательной.

Gravity isn't a force. So, there's nothing to block. But, even a second grader can build and operate anti-gravity machine. They're rather simple. Locate an empty drink bottle and remove the cap. The bottle can be of any type, 2-liter, individual serving, milk jug, etc., it doesn’t matter. Put a small hole on the bottle’s side somewhere close to the standing base. Put a finger over the pin hole and fill the bottle with water. It might be a good idea to test the hole before continuing. Make sure the pin hole allows for a noticeable stream of water to shoot out when the blocking finger is removed. Fill the bottle again blocking the pin hole. Now, climb a ladder, go to a second-story window, just hold the bottle above your head outdoors, use a balcony at a school building, stand on a chair, etc., allow the pin hole to start streaming water, pause for a second or two, and let go of the bottle so it enters freefall. Once released, water will no longer stream out of the hole on the side of the bottle. The water within the bottle has achieved weightlessness and is no longer under the influence of Earth’s gravity. And, just like any other amusement ride, it’s over rather quickly. The higher one takes the water bottle before dropping, the longer the inside of the chamber experiences no gravity.

[@russellstephan6844]

@@jaredsmith112 All models have their uses and limitations. But, to conceptualize gravity as a force is beyond a long stretch requiring it to be a very smart force since it impacts varying masses differently, i.e., differing masses respond to it *_exactly_* the same. A cue ball and a bowling ball when acted upon by the same force of a pool cue, accelerate at obviously different rates. Not so with gravity where the cue ball and the bowling ball accelerate at the *_exact_* same rate. All models are useful. Some models, however, are more accurate than others.

At around 9:30 where the box is moving and increasing the frequency of the light at the bottom of the box, are those photons increasing in energy compared to the frequency at the top of the box where they were emitted ? Would that increase in energy come from the acceleration of the box ? Incredible video as usual.

[@EugeneKhutoryansky]

From the perspective of a person outside the box, there is no gravitational field present and the photons are not increasing in energy. From the perspective of a person inside the box, there is a gravitational field present and the photons are increasing in energy because the gravitational potential energy they had when they were at the top of the box is converted into a higher photon frequency at the bottom of the box.

@@EugeneKhutoryansky Thank you ! This helps. :)

[@lukasaudir8]

Thank you Eugene, that's another great video, I just got confused on one part though, The accelerating box and a gravitational field cannot be told apart from each other, But how is that possible since in the accelerating box the clocks at the top and the bottom won't tick at different speeds because they are both at the same speed (the sensor on the top so register higher frequency but the clock runs at the same speed, doesn't it?), in the gravitational field the reason for the higher frequency is different than in the box, Also is there any way for the person in the box experience spaghettification (like objects falling into black holes) if you accelerate the box enough? Thank you for your content I really appreciate it

[@EugeneKhutoryansky]

When the box is accelerating, and the clocks are running at the same speed, the bottom clock reads a different frequency simply because it is moving towards the light pulses. Look at the animation, and count how many light pulses per second are hitting the bottom, as compared to how many light pulses per second are leaving the top. As for spaghettification, that is a function of the fact that the gravitational field is not uniform. A uniform gravitational field wouldn't do this. This is the same way you would be fine inside the accelerating box, regardless of the rate of acceleration, until you hit the floor of the box.

[@lukasaudir8]

@@EugeneKhutoryansky thank you for the reply, I do understand the light pulses frequency from the animation but the thing that is not really clear to me is that it is said someone inside the accelerating box cannot tell if they are inside such a box of just under the influence of a gravitational field, I cannot get this because if you attach one high precision clock at the top of the box and one high precision clock at the bottom, you could measure the difference between the two clocks after some time has passed, if the box is in the gravitational field the clocks will be out of sync but if the box is just accelerating the clocks will be perfectly synced, won't they? Wouldn't this violate this statement that someone cannot tell the difference from acceleration vs gravitational field?

[@xhalexj]

@@lukasaudir8 no because it is still measuring the same phenomenon regardless of what you call it. By finding that the clocks differ in time you would only draw the conclusion that SOME FORCE was affecting you, not to be able to tell which force it was. The point of the video (if I have understood it properly) is that because gravity and acceleration can be thought of as the “same thing” you measure them in the same way. Time is one method of measurement but not a method of determining between which force is present. I hope I’m right, that sounded really smart and I want to believe I understood the video hahaha

[@EugeneKhutoryansky]

Lucas, keep in mind that in Special Relativity, observers in different reference frames will disagree on the simultaneity of different events. Therefore, different observers will disagree about whether or not the clocks at the top and at the bottom of the box are synchronized. And they will both be equally correct.

[@martinhirsch94]

Lately, I did some research and found out mercury has Anti-Gravity properties! And, there has been some research on mercury to use as an engine, secretly, by USA. Other scientists also worked on mercury to find its anti gravity property. Having said that, what would be the best stream of science I should opt for from the two I mentioned to research on this topic? Aerospace engineering or Theoretical physics

Engineering will focus more on applied physics, stuff like circuit theory and statics and kinematics and dynamics. Theoretical physics will give you a broad knowledge of all of physics's sub branches. Engineering is just applied science, so either way you will learn a lot of physics concepts.

This is forbidden physics, go to linked in and search for gravity. There u will find me.

@@arinb.756 After completing Aerospace engineering I can easily work in a space agency to do research. Is it possible to study particular topics of theoretical physics all by yourself? so to gain more knowledge for the research

@@ffloxx what works for me in my classes is trying to picture everything in motion. You'll have to go and find problems to practuse yourself and phenomenon to observe outside if you want to understand physics ideas on an intuitive level. I would say take classes wheb you can, and talk to actual physics professors and students. Nothing will teach you better than a mentor.

@Lady Mercy so, aerospace engineering would be the best option right?
