SMARTER THAN EVERYONE...IN THEORY
By Angela Garrity, Guest Blogger
If one of the greatest minds the world has ever known were still living today, he’d likely laugh and say, “I told you so”, regarding a theory he gave to science. The joke is on us after astronomers observed a star orbiting the supermassive black hole at the center of the Milky Way – further solidifying Albert Einstein’s Theory of General Relativity from 1915, as correct.
If it’s been a minute, Space.com breaks it down and gives a great explanation around Einstein's Theory of General Relativity.
“In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.”
CNN states “Observations of the star were made by astronomers using the European Southern Observatory's Very Large Telescope in Chile's Atacama Desert. They saw that the star's orbit is shaped like a rosette.
Isaac Newton's theory of gravity suggested the orbit would look like an ellipse, but it doesn't. The rosette shape, however, holds up Einstein's theory of relativity.”
The study was recently published in the journal Astronomy & Astrophysics.
The article goes on to state, "Einstein's general relativity predicts that bound orbits of one object around another are not closed, as in Newtonian gravity, but precess forwards in the plane of motion," said Reinhard Genzel, in a statement. He is the director at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany.”
Also, way smarter than any of us.
