Can we break the laws of physics?

Laws of physics can be broken by going out of the Universe, just as the law of wearing a seat belt in a running car does not apply outside the car. Quantum uncertainty principle does offer a margin for breaking a classical physics law. A particle cannot pass through an opaque wall according to classical physics.

Can the laws of the universe be changed?

When we pointed our telescopes started looking at the most distant stars and galaxies in the visible universe, the laws of physics never changed. They are immutable and constant everywhere and for all time.

Are there physical laws?

Typically, there are only a few laws, but an infinite number of solutions. In string theory, certain features of physics that we usually would consider laws of nature — such as specific particles and forces — are in fact solutions. They are determined by the shape and size of hidden extra dimensions.

How are the physical laws governing gravity within another galaxy related to the physical laws governing the gravity of the earth?

How are the physical laws governing gravity within another galaxy related to the physical laws governing the gravity of the Earth? Physical laws that govern gravity within another galaxy are the same as those that govern gravity here on earth. Can one-dimensional motion have zero distance but a nonzero displacement?

Are physical laws constant?

No sooner has someone defined a “constant” than it is assumed to be just that, never varying at different times or places. There is no principle of physics that says physical laws or constants have to be the same everywhere and always.

Why does the universe follow laws?

Although this may not have been the OP’s angle, the question of why the universe obeys laws (…) is often used to argue that there must be a god somewhere to, as it were, write and enforce the laws.
