Can't there be any way to violates any law of physics? If in our earth we can't violate any law of physics can't we violate in any other planet?

    $\begingroup$ If a condition in the universe violates a law of physics, then that law wasn't really a complete picture and whatever revisions come about as a result of the new understanding are closer to the actual workings of the universe. Is it possible to violate the underlying reality that a formalized law approximates? No, that would preclude it being a law. $\endgroup$ – called2voyage Dec 3 '19 at 21:31

    $\begingroup$ It's not like the laws of physics come from a committee of lawgivers on Earth :) If there is a way to violate the known laws of physics (and there are probably many; this has happened many times before, and will likely happen again - our knowledge isn't perfect), it will work on Earth too. $\endgroup$ – Luaan Dec 4 '19 at 7:26

    $\begingroup$ Define “law of physics” and you’ll have your answer. $\endgroup$ – user76284 Dec 4 '19 at 7:39

  • $\begingroup$ Do I understand the question correctly; since relativity violates Newton's second law of motion, would achieving relativistic speeds on the surface of another planet be a valid answer to this question? $\endgroup$ – JollyJoker Dec 4 '19 at 8:39

If there is a way to violate a law of nature, it will become a law of nature as soon as it is discovered, studied and formalized into a scientific theory. Therefore, many new discoveries in science do violate (then current) laws of nature, but will not do so for very long. Often there are all sorts of medals and prizes involved too.

    $\begingroup$ This does not answer the question of whether it's possible for the laws of physics to be different elsewhere in the universe. $\endgroup$ – CJ Dennis Dec 4 '19 at 5:07

Universality of physics

As far as we know, laws of physics seem invariant both across space and time. It's not absolutely certain and taken for granted, there's lots of research probing to try and verify if perhaps something is slightly different far away or long ago, but to our best current knowledge the laws of physics work exactly the same in all faraway stars, because most reasonable changes in fundamental laws or constants of physics would cause some differences that would observable by us.

Our currently known laws of physics aren't final, we know that there are some gaps (mismatch between general relativity and quantum mechanics comes to mind) so there's probably some way to break the laws of physics as we know them. But that's not because we can't do it on earth and might somewhere else, it's because we would find out what the real laws of physics actually are and how they differ from our current understanding.

No.

That's because we believe the laws of physics to be the same everywhere (this itself is a consequence of the law of conservation of momentum, via Noether's theorem). Therefore, if you can't violate the laws of physics as we know them on Earth, you can't violate them elsewhere, too.

Well, it's possible that physics as we know them are somewhat different elsewhere, or on different scales (both microscopic and macroscopic). So if we manipulate our environs in particularly extreme ways, as with the large colliders or extreme lasers, or if we inspect very large structures, we may observe phenomena not predicted by our current laws of physics.

As an example, there are discussions whether acceleration by gravitation on cosmological scales "violates" Newton's Laws of Motion.

Everybody would agree that Newton's Laws are prototypical physics laws, so a deviating behavior is an obvious violation. (This is a standpoint opposing Allure's post.)

But indeed, as tuomas said, these new findings would be incorporated into the ever-evolving corpus of our knowledge of the world and thus become part of new laws which would not be violated anymore according to our knowledge.

The synthesis of these two is probably the following:

  1. Our knowledge of the world is incomplete, and so are the "laws" (actually algorithms for prediction) we derive from it.

  2. Even though this is pure speculation, my gut feeling is that most scientists would not assume that there is a reachable end of discoveries to be made.

  3. Which means that our knowledge will always be incomplete and our predictions will always be wrong somewhere or on some scale or under some certain condition.

  4. And, concluding this and answering your questions: Yes, it will almost certainly and for very principle reasons be possible to "violate" the known, and known to be incomplete, physics somewhere or somehow, given we have developed the means to observe these places or produce these conditions.

A note of caution: Our astronomical observations show that under a wide range of conditions and scales our ideas seem to hold pretty well, so it is virtually excluded that you can float on Mars, or even on some far-away exoplanet, if you cannot do it here. The "violations" will either be very subtle or very hard to produce or very far away (like in the next universe if you survive that wormhole).

    $\begingroup$ Not really - every physicist knows that Newtons Laws base on some proven false assumptions (like the universal time - and omitting any effects of relativity and speed-limits for information transport) . But we HAVE Einsteins general theory of relativity which fixes the known limits of Newtons laws. Regarding your 4 points - we will never know the truth .. we make assumptions, test them versus reality - and we see if our assumptions hold up or were wrong. Based on that there is always room for better theories. But not to an extend that violates what we already know. $\endgroup$ – eagle275 Dec 4 '19 at 13:18
