Gravity (from Latin gravitas, meaning 'weight' ), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light —are brought toward (or gravitate toward) one another.

Like a runt at a pool party, gravity just doesn't fit in when using Einstein's theory of relativity, which explains gravity only on large scales, "Gravity is completely different from the other forces described by the standard model," said Mark Jackson, a theoretical physicist at Fermilab in Illinois. This weakness also makes it the most mysterious, as scientists can't measure it in the laboratory as easily as they can detect its effects on planets and stars.

Sheldon Glashow, winner of the 1979 Nobel Prize in Physics, once called the Higgs the "toilet" of the standard model of particle physics. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides. After Einstein's calculations established that the speed of light, 3 × 108 m/s or about 186,000 miles per second, placed an upper bound on how quickly anything could be propagated through space, Newton's ideas suddenly looked vulnerable, at least in certain instances. Einstein spent the next 10 years formulating another theory, one that would reconcile Newton's basic gravitational framework with the upper bound the speed of light imposed, or appeared to impose, on all processes in the universe.

The latter is what Einstein did regarding his special and general theories of relativity. This article will briefly explore our understanding of gravity. What happens at the atomic scale is the key to understanding the mechanism to what causes gravity in the the oceans structure of fluid water molecules. :) Thanks One of the attractions of string theory is that it fundamentally explains gravity.

Although Einstein general theory of relativity is now a corner stone of modern physics, especially astrophysics, it still did not explain fundamentally why or how matter curves space, which still left the nature of gravitation a mystery.

Einstein’s theory of general relativity proposed that spacetime is curved by matter, and that free-falling objects are moving along locally straight paths, called geodesics, in curved spacetime.

According to general relativity, the effects of gravitation are caused by a spacetime curvature and not a force, as Newton had asserted. Turner, however, isn't despondent about humanity's quest for gravitons. If an object in space is massive enough – … One of the implications of Einstein's general theory of relativity is that gravity operated independently of the mass or the physical composition of objects. Will particle accelerators, however, eventually pop out a graviton?

Where does all this leave us?

This became known as Newton’s inverse square law of gravity.
