682 Quotes About Physics

The existence of matter and energy in the universe did not require the violation of energy conservation at the assumed creation. In fact, the data strongly support the hypothesis that no such miracle occurred. If we regard such a miracle as predicted by the creator hypothesis, then the prediction is not confirmed.

Infinity...is used in physics simply as a shorthand for "a very big number.

Rather than being handed down from above, like the Ten Commandments, they [the laws of physics] look exactly as they should look if they were not handed down from anywhere...they follow from the very lack of structure at the earliest moment.

Mars One has the power to show people around the globe what is possible if we just all work on one goal. No human has left Earth’s orbit since 1972 and no one ever ploughed beyond the moon into deep space. It’s finally time to inspire the world and make the next giant leap for mankind.

What does what we know or don't know have to do with the laws that govern the world?

Physicists believe that the Gaussian law has been proved in mathematics while mathematicians think that it was experimentally established in physics.

Given their current circumstances, things would have to be very bad indeed for Tilly to think the situation had gotten worse. Sure, they were all trapped in orbit around an alien space station that periodically changed the rules of physics and had killed a bunch of them, but now they’d decided to start shooting each other too.Yes, very bad.

Michael O'Toole had no difficulty recognizing which questions in life should be answered by physics and which ones by religion.

We have one real candidate for changing the rules; this is string theory. In string theory the one-dimensional trajectory of a particle in spacetime is replaced by a two-dimensional orbit of a string. Such strings can be of any size, but under ordinary circumstances they are quite tiny, ... a value determined by comparing the predictions of the theory for Newton's constant and the fine structure constant to experimental values.
