what is gravity? is it wave ? can it be repulsive? if not, then why the universe is continuously expanding?
Answers
Explanation:
gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and elsewhere in the universe and the structures and evolution of stars, galaxies, and the whole cosmos. On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second. At the surface of the Moon the acceleration of a freely falling body is about 1.6 metres per second per second.
yes it is a wave ,can't repulsive
Answer:
Gravity is the strongest force per square inch in our universe….
Our whole universe including space is made of matter in various stages of density.
Gravity is the attraction between the electrons protons and neutrons that makes up matter.
The denser the matter the stronger the force of Gravity or attraction and the longer this matter will stay together while the universe is expanding.
Space “aether” has far less density and therefore very little gravity and is matter streched to its limits by the big bang & the pure vacuum outside our universe. The vacuum is weaker per square inch than gravity but the surfaces area of our universes bubble is huge, therefore space does not have enough density or attraction force to oppose the vacuum and condense back into matter
