What is Einstein's Theory of Relativity? - Universe Today universetoday storybywill
is the system’s acceleration towards the speed of light.inertialThis means that more energy is required to maintain the object’s acceleration over time and that the speed of light is absolute. Not only would an object require an infinite amount of energy to achieve the speed of light, but its mass would also become infinite in the process. Another startling consequence was how mass and energy are interchangeable in this equation.
In other words, Newtonian Physics viewed space and time as separate and fixed. But by showing how time was relative to the observer in an accelerated reference frame, Einstein’s presented a four-dimensional geometry consisting of three dimensions of space and one dimension of time – aka. Spacetime! Almost immediately, scientists began adopting Einstein’s SR because of the way it resolved electromagnetism with Newton’s theories of motion and for how it did away with the need for an “aether.
In keeping with the laws of electromagnetism, Einstein ventured that gravity acted as a field rather than an instantaneous pull. The greater the mass, the more powerful the field within which objects would be attracted to each other. Another important issue was acceleration, which Einstein illustrated using another clever metaphor: a passenger on an elevator. If someone were to cut the cable, the elevator would begin to fall at a rate of 9.
For people aboard the station, this force creates the sensation of gravity. Depending on the radius and velocity of the station, the “” can be equal to Earth-normal gravity. Since the late 20th century, many noted scientists have proposed that such facilities could be the key to exploring and settling the Solar System – including Konstantin Tsiolkovsy, Werner von Braun, and Gerard K. O’Neill . The bottom line is that acceleration is indistinguishable from gravity in an inertial reference frame.
