Do black holes break laws of physics?
A singularity is a point of infinite density and infinite curvature of spacetime. The physicist Kip Thorne described the singularity as the point where all laws of physics break down. So, yes, black holes defy the laws of physics as we know them. This means that our laws of physics are incomplete.
Are there exceptions to Newton’s law of motion?
One corollary of Newton’s third law is that an object cannot exert a force on itself. The only exceptions to this rule are the fictitious forces which arise in non-inertial reference frames (e.g., the centrifugal and Coriolis forces which appear in rotating reference frames–see Chapter 7).
Where are Newton’s laws of motion valid?
Newton’s laws are valid for all situations where velocities are small (compared to the speed of light, ie relativity is not important) and where quantum effects are negligible (mostly where objects are much bigger than elementary particles).
Is Newtonian physics still valid?
We cannot call Newtonian physics to be invalid. It is still valid. It is just that it cannot precisely describe many of the new phenomena discovered later like quantum physics, theory of relativity and string theory.
What is inside a white hole?
In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it.
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist. They, too, are a possible outcome of Einstein’s theory.
Is Newton’s 2nd law f Ma always valid?
Is Newton’s second law always valid? Newton’s second law is valid only in inertial frames of reference. The frame of reference where the velocity is constant.
Is Newton’s Law accurate?
In a sense Newton’s laws are true in that they reproduce the behavior of many real world systems to within a reasonable accuracy. In a sense they are also not true, because they do not reproduce behaviors of real world objects accurately enough in all situations.
Does quantum mechanics disprove Newton’s laws?
Quantum mechanics (QM) clearly violates Newton’s First Law of Motion (NFLM) in the quantum domain. In the process, a general argument is made that such a disparity may be found commonly for a wide variety of quantum predictions in the classical limit.
Are Newtonian mechanics true?
In other words Newtonian physics are an accurate enough approximation to the more precise theory, special relativity. Other than that some conservation laws from Newtonian physics carry on to the rest of physics, for example conservation of energy and momentum.
