But Einstein wants to understand the real world, and the real world doesn’t work that way.
Einstein realized that his theory failed for accelerations, but in our universe everything accelerates, at bumpy roads, jet planets, on a subway car, everything is accelerating, so there was a defect in special relativity.
On Einstein’s imaginary journey, if his speed varies at all, his theory, his notion of how objects behave in time and space falls apart.
His scientific mind wants to do apply to all cases.
Einstein knows there for his theory to work, it has to account for everything in the universe, and that includes the pervasive and invisible force that holds everything together.
Gravity, gravity is everywhere, gravity holds us to the floor, gravity holds the sun together, the solar system together, where was gravity in special relativity.
Einstein wants to expand his special theory of relativity into a general theory of relativity, a theory that would explain not just time but also gravity, he realizes he will be fighting more than two centuries of scientific thought, and his hero SirIsaac Newton.
It’s 1907 and 28 yearold Albert Einstein is still a patent office bureaucrat, it’s been two years since he published his special theory of relativity, and ambitious Einstein decided to advance even more radical interpretation of the universe, a general theory of relativity, doing this will require him to take on his scientific hero SirIsaac Newton.
In Einstein’s time, Isaac Newton was god.
Newtown was the founder of modern science, this is the actual first edition of Newton Principia Mathematic of 1687, this priceless artifact is the very, very famous book, which became the foundation of universal physics for centuries, until Einstein upset the apple cart.
It’s been almost 250 years since apple fall from the legendary tree on Isaac Newtown’s estate, giving Newtown inspiration to formulate his law of gravity.
Newtown said that if a object falls, it’s because there is a mysterious force call gravity
