Curved Spacetime Quotes

Spacetime tells matter how to move; matter tells spacetime how to curve.

Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.

When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter.

At present every coachman and every waiter argues about whether or not the relativity theory is correct.

When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity to advanced high school students.

I heard that in relativity theory, space and time are the same thing. Einstein discovered this when he kept showing up three miles late for his meetings.

In my relativity theory I set up a clock at every point in space, but in reality I find it difficult to provide even one clock in my room.

I am exclusively occupied with the problem of gravitation and hope with the help of a local mathematician friend [Marcel Grossman] to overcome all the difficulties. One thing is certain, however, that never in life have I been quite so tormented. A great respect for mathematics has been instilled within me, the subtler aspects of which, in my stupidity, I regarded until now as pure luxury.

To say that a body or its gravitational field 'bends in space' in its vicinity is the discuss visual space in acoustic terms.

If you look at Einstein's equations and put in low speeds and low gravity, they become Newton's equations.
