The discussion highlights contradictions in physics, particularly between General Relativity (GR) and Quantum Mechanics, which describe different scales and conflict when applied to each other's realms. Newton's law of gravity is cited as an approximation that, while useful, is not entirely accurate compared to GR. The conversation emphasizes that many physical laws, especially from the 19th century, were based on the measurement accuracy of the time. However, the laws of conservation of energy and mass remain uncontradicted, as they can transform into one another through processes like fusion and fission. Overall, the complexities of physics reveal ongoing debates and the evolution of understanding in the field.

Hi...I don't know a whole lot about physics but I'm getting there.

I have heard a lot of times about different things that have contradicted a few laws of physics. I don't think I've ever seen a specific example, just claims. The last one I heard was on a subatomic level. My question:

Do you know of any such things? (exclude the beginning-of-the Earth stuff)
 
Physics news on Phys.org
That's an awfully broad question, but I think perhaps the event you heard about "on the subatomic level" might be a reference to the famous conflict between the two leading physical models for the universe; General Relativity and Quantum Mechanics.

Does that sound familliar?
 
well you see the thing is there are a lot of mathematical formulations from Newtonian physics through most of the 19th century that are only approximations based upon the degree of measurement accurayc that was attainable with the technology at the time. A perfect example is enwtons law of gravity. it is a good approxiamtion for purposes of calculation, but its not actually correct. GR is a much better approximation, but is much more difficult to calculate with, so most people use the more flawed but easier law formulated by Newton.

There is also what LURCH mentioned about the conflicts between GR and Quantum Mechanics, because the two theories describe entirely different scales, and conflict with each other when one is applied to the others realm.

the only real "laws" of physics that have never been contradicted at all are the laws of conservation once conservation of energy and mass are combined (since one can be changed into the other through fusion/ fission).
 
I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
