![]() It pulls you toward one side of the chamber, and it allows you to walk normally along what feels like the bottom of the chamber. Toward one side of the chamber, you feel a force that feels just like gravity does. To understand this concept, imagine that you’re in an impenetrable chamber-you can’t hear, see or otherwise know anything about what’s going on outside of the chamber. Thinking about how he might be able to incorporate acceleration and gravity into his theory, he came up with something we now call the equivalence principle. This occurred a few years after special relativity and his other breakthrough papers from 1905. In 1907, Einstein had his first important conceptual breakthrough that placed him on the road to general relativity. The general theory of relativity was not only a theory of space and time, but also provided us with a deeper, more powerful way of thinking about the force of gravity. Although it took him another decade, Einstein eventually came up with an expanded and completely general form of his theory. Shortly after publishing his special theory of relativity, Einstein began to work toward creating an even more complete and far-reaching theory of space and time. In at least two ways, Einstein’s theory of special relativity left us with important and unanswered questions. This made it difficult to reconcile special relativity with this aspect of Newtonian gravity. According to special relativity, nothing can move faster than the speed of light. Secondly, in the Newtonian theory of gravity, the accepted theory of the time, gravity’s attraction works instantaneously, pulling bodies together across great distances in space without any time delay.

Watch it now, on Wondrium.Īlbert Einstein published the special theory of relativity in 1905. This is a transcript from the video series What Einstein Got Wrong. In this sense, special relativity is like a theory that describes how a car moves and behaves with its cruise control on but knows nothing about the brake pedal or the accelerator. Even Einstein himself was aware that it was incomplete from early on.įirstly, special relativity can only be applied to objects that are moving at a constant rate of speed. (Image: Fernando Batista/Shutterstock) The Special Theory of Relativity: LimitationsĮinstein’s theory of relativity-now known as the special theory of relativity-describes how lengths in space and durations of time are different to observers moving at different speeds, in different frames of reference.Īlthough special relativity predicts many observed phenomena correctly, this theory is also incomplete. ![]() Einstein’s equivalence principle would help to address these issues, though the equations would take years to refine. By Dan Hooper, Ph.D., University of Chicago The special theory of relativity, brilliant as it was, still had some holes to account for after its initial conception. ![]()
