Albert Einstein introduced his theory of General Relativity in 1915 (New Site). This theory includes a field equation for gravity, which consists of three terms: two tensors that represent space-time and the energy-momentum tensor. The energy momentum tensor represents the matter and energy in the universe which bends space-time to produce gravity (lecture 1). His equation is seen in Figure 1. Figure 1 On the right side of the equation is the matter and energy tensor and, on the left, are the two space-time terms (lecture 1). Despite the incredible paradigm shift this equation and the rest of General Relativity had, it also had a profound implication that tremendously bothered Einstein (New Site). Einstein’s field equation implies that…
finally beginning to prove Einstein’s theory absolutely correct. Scientists from around the world have stated that Einstein’s interpretation of the expansion of the universe has evidenced right with “incredible accuracy” and is handling to support the scientists to conclude and comprehend the unfathomable hastening of the universe. Is Einstein’s Theory of relativity really all what it adds up to be? Does it really matter?? The most important discovery in Physics within the past 200 years is…
a point where the universe is so hot that it formed an opaque “wall” of sorts, blocking our view of the Big Bang (Krauss). According to data from the largest atom-smashing experiment ever performed, the universe behaved like a very dense, super hot liquid in the immediate aftermath of the big bang. Physicists at the Large Hadron Collider, near Geneva, Switzerland, recently re-created the conditions of the Big Bang using the ALICE detector. The scientists at the LHC, Large Hadron Collider,…
Einstein made a name for himself when he rewrote Isaac Newton’s law of gravity in what is called the general theory of relativity. The general theory of relativity states that gravity is created because matter curves space. Before that he was seen as a man that wasn’t going to do anything important in his life. He was barely able to pass college. Many viewed him as a fun loving guy, but not as the man that would forever change science. Throughout the rest of his life, until he died in April…
If an astronaut were to go towards a black hole time would be much slower for them than somebody on Earth. Eventually they would reach the event horizon where time stands still. For this reason an outside observer will never really see the astronaut fall into the black hole (Temming, Maria) This happens because black holes are so massive they warp spacetime. Spacetime is a four dimensional combination of width, height, depth and time.(Spacetime, Relativity and Quantum…
burning has run out, what’s life is the core; In a black hole, otherwise known as a singularity. The space surrounding the singularity, where the escape velocity must be equivalent to the speed of light is what’s called the event horizon; or “the point of no return.” (Seidel). Speculation of black holes has dated back as early as 1783 when John Michell theorized that there might be an object massive enough to have an escape velocity greater than the speed of light. Simon Pierre LaPlace theorized…
This was also known as the theory of gravity. Several scientist say that the theory of general relativity only makes sense if the object have the same mass. Some people may wonder what the importance of inertial and gravitational properties of mass play in the discovery of general relativity. Well, these are coordinating systems that accelerate to each other, so therefore you need the gravitational fields for the theory of general relativity. Albert discovered gravitational waves in 1916. Space…
General relativity is fundamentally incompatible with quantum mechanics- they have been at odds with each other since its discovery in 1915- relativity breaks down at the subatomic level and vice versa. A conjecture by two physicists may finally reconcile relativity with quantum mechanics and put an end to the chain of inconsistencies began by Hawking’s information paradox. Albert Einstein first discussed the concept of quantum entanglement in a 1935 paper co-written with his colleagues Boris…
the theory of relativity, The quantum theory of light, or Brownian movement? Also Einstein, was a genius, with an IQ of 160, which is 20 over genius. Moreover on his intelligence, his brain was larger than most, and head also larger, but not so at his final years. Without Albert Einstein, we wouldn't have the Atomic Bomb, which isn't necessarily a good thing, and his discoveries revolutionized mankind forever. Discoveries In 1905, a 26 year old had published something, a theory, and it was…
that the Universe is expanding and galaxy clusters are far apart. The theory of general relativity proposed by Albert Einstein also predicts this expansion. If the components of the Universe are separated, this means that in the past, they were closer together, and going back enough in time, we come to the conclusion that everything came out of a single mathematical point (what is called a singularity), in A fireball known as Big Bang or Big Bang. The discovery in the 1960s of cosmic background…
