What is the nature of gravity?

Question

And what is the nature of Space without any material?

Answer 1

actually it wouldn't float around, everything would break up into atoms held together by electromagnetic bonds. but of course...impossible.

the second part, space actually is, the void of matter, so...what is space when it is space? I dunno, space as we know it isn't true "space". But i assume if there was nothing in it, nothing would happen haha

Answer 2

Im not even sure gravity exists it could just be very strong EM fields we dont know about or something or it could work like we think it does today but anyhow it has the effect of pulling objects closer together. Say you have a larger object and a smaller one the larger object will pull the smaller one closer as will the smaller one pull the larger but the difference is in how they move.

And to me the nature of space without any material energy or mater is to become mater or energy :) For all we know we are constantly expanding and growing in size along with everything around us anything possible I guess. Figureing out what isnt possible is also tricky cause ud have to be a know it all like me.

Answer 3

The simplest and most honest answer to your question is that nobody knows....not even the best scientific minds of our day. But there are a lot of theories out there, some of which are even being tested. Try a search on wikipedia if you want all the gory details about what the complicated theories are. Basically, scientists since Einstein's day have been searching for what is called the "Theory of Everything" which would explain all the forces we now know of in one compact theory. The forces we know of now are gravity, electromagnetism, strong and weak nuclear force...(don't quote me on that, but I'm pretty sure that's right). Each of these forces has a strange interaction with the other that
we haven't been able to prove a theory about. We just know that they interact with one another in a way that suggests they are closely related.

Answer 4

Gravitation, the force of attraction between all objects that tends to pull them toward one another. It is a universal force, affecting the largest and smallest objects, all forms of matter, and energy. Gravitation governs the motion of astronomical bodies. It keeps the moon in orbit around the earth and keeps the earth and the other planets of the solar system in orbit around the sun. On a larger scale, it governs the motion of stars and slows the outward expansion of the entire universe because of the inward attraction of galaxies to other galaxies. Typically the term gravitation refers to the force in general, and the term gravity refers to the earth's gravitational pull.

Gravitation is one of the four fundamental forces of nature, along with electromagnetism and the weak and strong nuclear forces, which hold together the particles that make up atoms. Gravitation is by far the weakest of these forces and, as a result, is not important in the interactions of atoms and nuclear particles or even of moderate-sized objects, such as people or cars. Gravitation is important only when very large objects, such as planets, are involved. This is true for several reasons. First, the force of gravitation reaches great distances, while nuclear forces operate only over extremely short distances and decrease in strength very rapidly as distance increases. Second, gravitation is always attractive. In contrast, electromagnetic forces between particles can be repulsive or attractive depending on whether the particles both have a positive or negative electrical charge, or they have opposite electrical charges (see Electricity). These attractive and repulsive forces tend to cancel each other out, leaving only a weak net force. Gravitation has no repulsive force and, therefore, no such cancellation or weakening.

The gravitational attraction of objects for one another is the easiest fundamental force to observe and was the first fundamental force to be described with a complete mathematical theory by the English physicist and mathematician Sir Isaac Newton. A more accurate theory called general relativity was formulated early in the 20th century by the German-born American physicist Albert Einstein. Scientists recognize that even this theory is not correct for describing how gravitation works in certain circumstances, and they continue to search for an improved theory.

EARTH'S GRAVITATION
Gravitation plays a crucial role in most processes on the earth. The ocean tides are caused by the gravitational attraction of the moon and the sun on the earth and its oceans. Gravitation drives weather patterns by making cold air sink and displace less dense warm air, forcing the warm air to rise. The gravitational pull of the earth on all objects holds the objects to the surface of the earth. Without it, the spin of the earth would send them floating off into space.

The gravitational attraction of every bit of matter in the earth for every other bit of matter amounts to an inward pull that holds the earth together against the pressure forces tending to push it outward. Similarly, the inward pull of gravitation holds stars together. When a star's fuel nears depletion, the processes producing the outward pressure weaken and the inward pull of gravitation eventually compresses the star to a very compact size.

Answer 5

The nature of gravity makes clumsy a@$ peope like me drop and knock everything over and spill my drink all the time. If we didn't have gravity I wouldn't have that problem everything would just float around.

Answer 6

Gravity is a manifestation of space associated with matter.

Answer 7

It’s fundamental, as it’s God-Creator’s will, moreover gravity mass coincides with inertia mass! Just like 2x2=4.

Answer 8

It's space being warped by mass.

Answer 9

GRAVITON

hey who put bad answer!

Gumby says Graviton damn it! LOL

are you saying Spock is wrong?!
