The physics of two times may be relevant in the solution to the problem of time in quantum gravity and in the explanation of dark matter. Finding nontrivial solutions of the generalized gravitational field equations corresponding to the 8-dim cotangent bundle (phase space) of the 4-dim spaceu...
Watch this video explaining Newtonian gravity, fromPBS Digital Media's Crash Course. Learn more about gravity and how the warps and ripples in space work, from theAustralian Academy of Science. Read astrophysicistEthan Siegel's explanation of how gravity bends(and unbends) space, generating gravit...
Statement-2: In the absence of gravity there will be no force to prevent the rise of liquid due to surface tension. AStatement-1, is true, Statement-2 is true, Statement-2 is correct explanation for statement-1 BStatement-1 is true, statement-2 is true, statement-2 is NOT a correct...
This "hierarchy problem" seems odd to most physicists. Sure, it could just be the way the universe is, with no need for an explanation, but that isn't very satisfying. Instead, it seems like an opportunity to dig deeper into the physics of the fundamental forces and see if there's any...
Albert Einstein, who won the Nobel Prize in Physics in 1921, contributed an alternate theory of gravity in the early 1900s. It was part of his famous General Theory of Relativity, and it offered a very different explanation fromNewton'sLaw of Universal Gravitation. ...
What this means is that space and time are connected – if you move really fast through space, time slows down for you compared to someone who is moving slowly. This is why astronauts – who are moving very fast in space –age a tiny bit more slowly than people on Earth. ...
In the equatorial ocean, it has been considered a potential mechanism for deep jet formation (Hua et al., 1997), and a possible explanation for similar phenomena observed in the upper ocean (Richards and Edwards, 2003). A necessary condition for inertial instability is the existence of ...
In this regard, various attempts have been made to find an alternative such that it modifies Einstein gravity in the large scales (IR limit). Massive gravity is one of the alter- natives that modifies Einstein gravity by giving the graviton a mass and provides a possible explanation for the ...

(5.24) 14The second expression requires some explanation. Applying (5.5) one obtains c l±s((ts,F , c)) = 24 m(m ∓ s)(m2 ± ms − 3s2)fmf±s−m + O(f 3). m∈Z (5.15) One can check this expression does not depend on f0, fs and f−s, which can be made more...
