What is gravity and how its work??

Gravity (from Latin lordliness, which means 'weight'), or gravitation, could be a phenomenon by that all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) each other.





On Earth, gravity offers weight to physical objects, and therefore the Moon's gravity causes the ocean tides. The attraction of the first frothy matter gift within the Universe caused it to start coalescing, forming stars—and for the celebrities to cluster along into galaxies—so gravity is to blame for several of the large-scale structures within the Universe. Gravity has associate infinite vary, though its effects become progressively weaker as objects get any away.





Gravity is most accurately delineated  by the overall theory of relativity theory (proposed by Einstein in 1915) that describes gravity not as a force, however as a consequence of the curvature of spacetime caused by the uneven distribution of mass. the foremost extreme example of this curvature of spacetime could be a region, from that nothing—not even light—can escape once past the black hole's event horizon.However, for many applications, gravity is well approximated by Newton's law of universal gravitation, that describes gravity as a force that causes any 2 bodies to be interested in one another, with the force proportional to the merchandise of their lots and reciprocally proportional to the sq. of the gap between them.



Gravity is that the weakest of the four elementary interactions of physics, some 1038 times weaker than the interaction, 1036 times weaker than the magnetic attraction force and 1029 times weaker than the weak force. As a consequence, it's no important influence at the extent of subatomic particles.In distinction, it's the dominant interaction at the megascopic scale, and is that the explanation for the formation, form and mechanical phenomenon (orbit) of astronomical bodies.



The earliest instance of gravity within the Universe, probably within the sort of quantum gravity, supergravity or a attractive force singularity, together with normal house and time, developed throughout the Max Karl Ernst Ludwig Planck epoch (up to 10−43 seconds once the birth of the Universe), probably from a aboriginal state, like a false vacuum, quantum vacuum or virtual particle, in a very presently unknown manner. tries to develop a theory of gravity per quantum physics, a quantum gravity theory, which might permit gravity to be united in a very common mathematical framework (a theory of everything) with the opposite 3 elementary interactions of physics, area unit a current space of analysis.

  1. No SCIENTISTS wants to review Alternative theories against GR. They feel it is waste of time. But in my view they are wasting whole life time by following GR.

  2. I think quantum gravity is the point at which gravity reverses and is opposite to cosmological gravity.

How earthquake happend !

The Earth is a dynamic planet, and one of the ways this dynamism manifests itself is through earthquakes. These sudden and often violent tremors can cause widespread damage and loss of life. But what exactly causes these ground-shaking events? The Theory of Plate Tectonics The Earth's surface is made up of a patchwork of tectonic plates that float on the molten rock of the mantle. These plates are constantly moving, albeit very slowly, in response to the forces of convection within the mantle. When two plates meet, they can either slide past each other, collide and crumple, or diverge. It is at these plate boundaries that most earthquakes occur. Friction and Release As two plates grind against each other, friction builds up along the boundary. This friction can eventually become too much to overcome, and the plates will suddenly slip past each other. This sudden release of energy is what causes an earthquake. The Anatomy of an Earthquake The point below the Earth's ...

What is neutron star 🌟??

A star is that the rolled core of an oversized star that before collapse had an entire mass of between 10 and twenty 9 star masses. Neutron stars ar the tiniest and densest stars, excluding black holes, theoretic white holes, quark stars and strange stars. heavy particle stars have a radius on the order of 10 kilometres (6.2 mi) and a mass of concerning one.4 star masses.They result from the star explosion of a vast star, combined with implosion, that compresses the core past star star density thereto of atomic nuclei. Once formed, they not actively generate heat, and funky over time; however, they will still evolve a lot of through collision or accretion. Most of the basic models for these objects imply that stars ar composed just about entirely of nucleons (subatomic particles with no web electrical charge ANd with slightly larger mass than protons); the electrons and protons gift in ancient matter combine to produce neutrons at the conditions in an extr...

Black Holes: Where Space Gets Weird (and Wonderful)

Blackhole The very name conjures images of cosmic monsters, swallowing up anything that gets too close. But the reality, while still mind-bending, is even more fascinating than science fiction could dream up. Let's take a dive into these mysterious giants of the universe: Spacetime Slingshot: Imagine gravity, not as a gentle pull, but as a colossal cosmic trampoline. That's essentially what a black hole is. Its immense mass warps spacetime itself, creating a region where gravity is so strong not even light can escape. Think of it as a one-way door for anything that crosses the event horizon, the point of no return. Cosmic Detectives: We can't directly see black holes, but we know they're out there thanks to their gravitational influence. Imagine a cosmic game of tug-of-war, where stars near a black hole get stretched and whipped around like cosmic yo-yos. By studying these stellar tantrums, astronomers can deduce the presence and even estimate the size of these inv...

``hubble telescope`‌‌‌‌‌‌‍` what is it?

From the dawn of group to a mere four hundred years agone, all that we tend to knew regarding our universe came through observations with the oculus. Then uranologist turned his telescope toward the heavens in 1610. the planet was certain  associate degree wakening. Saturn, we learned, had rings. Jupiter had moons. That nebulous patch across the middle of the sky referred to as the Milky Way Galaxy wasn't a cloud however a group of unnumbered stars. among however many years, our notion of the wildlife would be forever modified. A scientific and social group revolution quickly ensued. Edwin Edwin Powell Hubble The Edwin Powell Hubble house Telescope is called in honor of stargazer astrophysicist. More on Dr. Hubble In the centuries that followed, telescopes grew in size and complexness and, of course, power. They were placed faraway from town lights and as so much on top of the haze of the atmosphere as doable. astrophysicist, for whom the Edwin Po...
