This is a theory still being developed in physics that attempts to take account of both quantum mechanics and general relativity. If a successful description of quantum gravity could be achieved, then this might amount to a 'theory of everything' - no small matter!
The discussion of gravitational singularities must be considered as a theorem. In two hypothetical situations, the implosion of a planetary body or the universe spatially closed. In either case, the laws of physics as we know them cease to operate and gravitational singularities would be...Read More
Super-gravity is a type of quantum theory. This theory includes consideration of gravity along with the other fundamental forces. These other three are the electromagnetic force, the weak nuclear force, and the strong nuclear force.. Super gravity is a field theory proposing that elementary...Read More
Yes, this is a curious feature about the Hudson Bay area of Canada. There is a degree less gravity, as was discovered in the 1960s when scientists were charting the Earth's global gravity fields. They discovered found a weakness, although slight.
This would amount to some...Read More
It is tempting to imagine that an object could exist without gravity if it was placed outside the Earth's atmosphere and 'pull'. After all, objects and people inside space craft that have left the Earth float and have little control over reaching other objects.
However, E...Read More
The sun's gravity is 28 times that of the Earth's. The more mass an object has, the stronger its gravity will be. Therefore the sun attracts the Earth towards it and the sun's gravity is responsible for the Earth's regular orbit through the solar system.
The Earth travels...Read More
Gravitational waves differ from gravity waves. Gravitational waves are ripples in space-time that travel outward from a source. In the twentieth century the existence of gravitation waves was proved, but not directly observed. The theory explains that a massive object like Earth distorts...Read More
