Special relativity tells us motion warps space and ... which quantifies a body’s resistance to acceleration, must always equal gravitational mass, which quantifies a body’s response to gravity.

Einstein’s special relativity, which he formulated in his “miracle year” of 1905, was a theory that revolutionised our ideas of space and time – and ultimately paved the way for some even ...

His theory of special relativity stemmed from his desire to ... the effects of gravity are indistinguishable from the effects of acceleration for an observer in a small region of spacetime.

Albert Einstein had described the special theory of relativity in 1905 ... The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years, he published ...

Since, according to Einstein's special theory of relativity, time moves slower ... Gravity's tug and upward acceleration in zero gravity both pull you to the floor. The physics of both events ...
