We all have  heard of Einstein and many of us have heard of his general theory of relativity. But the question is do we actually understand what it means. Scientists today are still trying to completely understand Einstein’s field equations. But then five minutes we can gain a basic and insightful understanding on this truly groundbreaking topic to start we’re going to break down the statement General Theory of Relativity. The general theory is simply states that something accepted and useful in the physics world and also big or general in consequence. Now theory of  relativity tells us basically how this theory is applied. That is it’s relative to something else. If you think about it everything is relative. For example if you’re waiting at a bus stop and see cars passing by they are moving relative to you. However if you’re in a car and see someone at a bus stop then they are the ones that appear to be moving position motion acceleration etc. They’re all relative to the observer. And if you change where you’re making your observations from or your frame of reference then different things appear to be in motion the earth the other planets [email protected] sun the Galaxy they’re all in motion depending on where you place your frame of reference. Awesome. We now understand that we’re talking about a major theory that’s relatively applied. So now before we dive into general 50 we’re going to gain a better understanding of its development by first taking a look at special theory of  relativity. Special theory of relativity was posed by Einstein ten years prior to general TV and it’s the theory where we equals empty squared which basically describes the relationship between mass and energy and is used often in Quantum and particle physics. Special theory of relativity itself has two postulates.That is frames of reference there moving constant speeds. The second is that the speed of light is constant for all observers. Meaning that light travel is independent of the speed of the observer. For example let’s imagine a spaceship travelling at half the speed of light fires a laser beam from the front of the ship. You might think that the speed of the laser would be one point five times the speed of light. However as we said before nothing can travel faster than the speed of light. So Einstein determined using the equation speed equals distance over time. Therefore the speed of light to remain the same distance and time would have to shift which happens in what you call length contraction and time dilation. To see how this relates to general TV. Let’s take the concept that spacetime the interwoven fabric of the four dimensional universe can be stretched thin and manipulated as shown in the previous example. This concept proved to be the very basis upon which Einstein formulated his general theory of relativity. This and one other very important idea the equivalence principle the equivalence principle simply stated shows the equivalents of the gravitational force and the force experienced in accelerated frames of reference or non inertial friends. Let me explain. Say you’re standing in an elevator and you take a ball out of your pocket. You let go and watch it drop to the floor. If our to where you are you probably assume you are at rest on Earth. However you could also be inside an elevator in space that has a constant acceleration therefore causing the appearance of gravity. Say you’re in an elevator again but this time you aren’t touching the ground. And when you pull a ball out of your pocket and go it goes nowhere. Now you may be thinking a I’m in space by Einstein again propose another option. You could be on Earth in freefall with the elevator having a constant acceleration and therefore causing the appearance of weightlessness. Fitting these two pieces of the puzzle together will spacetime in the equivalence principle took a lot of complex math and reasoning. After about a decade Einstein finally cracked the code with his ten equations of general TV. As a side note even though this looks like it’s one equation it’s actually 10 because involves some crazy Tensor Calculus matrices and other insane math. And so now the question is what does this equation mean. Well it basically describes very specifically how mass and energy and momentum and pressure are distributed throughout the universe as well as how they bend spacetime. Is this curvature of spacetime that then influences how mass energy etc are spread. In short to quote one of Einstein’s later colleagues John Wheeler spacetime tolls matter how to move matter till space time how to curve results of such a discovery are incredible. First of all which we call gravity is actually the result of the earth bending spacetime and it’s the same reason that the Earth orbits the sun. Other implications of this theory is that it predicted black holes in gravitational waves many many years before they were discovered. It also permits the existence of wormholes and the theoretical possibility of time travel Einstein’s General Theory of  Relativity true was an incredible breakthrough arguably one of the most monumental in all the history of modern science. These equations are genius and now they have a basic well-built foundation of them what does that make you. New parts of his theories are still being discovered and explained and it is evident that is equations still contain many secrets to the universe. Now that you have gained a basic understanding of some of Einstein’s greatest life work in only five minutes the question is what’s next. That is up to you but he could with your knowledge of the universe. The possibilities are endless.

THEORY OF RELATIVITY

In 1905, Albert Einstein determined that the laws of material science are the equivalent for all non-quickening spectators, and that the speed of light in a vacuum was free of the movement everything being equal. This was the theory of unique theory of relativity. It presented another structure for all of material science and proposed new ideas of reality. 

Einstein at that point went through 10 years attempting to incorporate quickening in the hypothesis and distributed his hypothesis of general theory of relativity in 1915. In it, he verified that huge items cause a twisting in space-time, which is felt as gravity. Two items apply a power of fascination on each other known as “gravity.”. Sir Isaac Newton evaluated the gravity between two articles when he detailed his three laws of movement. The power pulling between two bodies relies upon how huge every one is and how far separated the two untruth. Indeed, even as the focal point of the Earth is pulling you toward it (keeping you immovably stopped on the ground), your focal point of mass is pulling back at the Earth. In any case, the more huge body scarcely feels the pull from you, while with your a lot littler mass you end up immovably attached gratitude to that equivalent power. However Newton’s laws accept that gravity is an intrinsic power of an item that can demonstration over a separation.

THEORY OF RELATIVITY

Albert Einstein, in his hypothesis of special theory of relativity, verified that the laws of material science are the equivalent for all non-quickening eyewitnesses, and he demonstrated that the speed of light within a vacuum is the equivalent regardless of the speed at which an onlooker ventures. Accordingly, he found that existence were interlaced into a solitary continuum known as space-time. Occasions that happen simultaneously for one eyewitness could happen at various occasions for another. As he worked out the conditions for his general hypothesis of theory of relativity, Einstein understood that monstrous articles caused a contortion in space-time. Envision setting a huge body in the focal point of a trampoline. The body would press down into the texture, making it dimple. A marble moved around the edge would winding internal toward the body, pulled similarly that the gravity of a planet pulls at rocks in space. Gravitational lensing: Light around an enormous item, for example, a dark opening, is bowed, causing it to act as a lens for the things that lie behind it. Space experts routinely utilize this strategy to study stars and cosmic systems behind monstrous items. Einstein’s Cross, a quasar in the Pegasus heavenly body, is a fantastic case of gravitational lensing. The quasar is around 8 billion light-years from Earth, and sits behind a cosmic system that is 400 million light-years away. Four pictures of the quasar show up around the system on the grounds that the exceptional gravity of the cosmic system twists the light originating from the quasar.
