WebMay 2, 2024 · Answer (1 of 7): Does lightning repel gravity? Yes it can, although certain conditions need to be met. Sometimes lightning can fulfill the required Energy to Quantum Mass Ratio, so that lightning can strike upwards from storm clouds, as shown in the image above. Similar to how Cosmic X-Rays es... WebAug 14, 2010 · In other words: positive mass is linked to positive energy, positive time and attractive gravity. Reversely: negative mass must be linked to negative energy, negative time and repulsive gravity. 1154. Posted August 13, 2010. Energy has a t^2 component, so reversing time won't reverse energy. Evil Liar (or so I'm told)
WebDoes gravity attract somethings or repel nothing? And how do we know? The way I’m thinking about it is a little weird but instead of two objects being attracted by one another’s mass, the repellant force of gravity would simply push the two objects together because there is less nothing between them then outside of them. WebI think the basic problem here is that a magnetic gradient is required for levitation, whereas the Earth's magnetic field is very close to uniform on the scale of any human-scale crafts. Try using the right-hand rule to figure out the direction of the magnetic force from a uniform magnetic field at two points on opposite sides of a circular current loop (i.e. each point is …
WebAnswer (1 of 4): Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportionalto the square of the distance between their centers.

WebSince electricity and magnetism can both attract and repel, is there a school of thought that gravity does the same? EDIT: some googling led me to this article that posits that "antigravity" could be a reason the universe is expanding.
