# With the advent of General Relativity, do Newtonian Mechanics really describe the universe correctly? [duplicate]

Do concepts in Newtonian Mechanics such as Normal force, etc. still hold true? I don’t mean if you use newtonian mechanics, will it still chunk out the correct computation. What i mean is that does the equations of Newton accurately describe the universe? Im also pointing to Newton’s concept of gravity where objects pull, whereas Einstein’s predictions says that gravity pushes via waves in space-time.

• Does general relativity accurately describe the Universe? If so, how do I use it to predict the Super Bowl winner? – WillO Dec 18 '17 at 14:23
• One of the signs of the "rightness" of a modern new theory, is that it successfully encompasses and returns to the old theory, with the right values in it's equations. So whatever theory supersedes GR, one of the first checks of it is to see can we get GR back out of it, given the appropriate conditions. A line in a textbook that sticks with me is: "some of the material presented here is wrong, but if we are really, really lucky, most of it is wrong" – user178231 Dec 18 '17 at 15:04
