Laws of nature Definition and 26 Threads

Hello everyone, being new here I would like to introduce myself briefly. By nature I am a curious and ingenious person with an open mind. Although my professional background originates from finance, accounting analysis and business management, I have been studying physics. My approches are...

I found some interesting discussions in this site (e.g: https://www.physicsforums.com/threads/smolin-lessons-from-einsteins-discovery.849464/; https://www.physicsforums.com/threads/relatismo-to-the-max.83885/) which are related to Lee Smolin's ideas that laws are not immutable and can therefore...

There are some theoretical processes (like vacuum decay in quantum field theory) that could change the physical constants of the universe. Similarly, in inflation theory, various models predict that multiple regions that would stop inflating would become "bubble universes" perhaps with different...

Have you ever discovered any animals which as you read about their activities or life cycle, just seemed so horrific that their very nature almost felt like an argument against Divine Creation? If Satan had a zoo, what kinds of animals from this Earth do you think he would put in it?

There are several models of brane cosmology (https://en.wikipedia.org/wiki/Brane_cosmology) and several physicists working in this field (e.g Lisa Randall and Raman Sundrum), but as you will notice, apparently they are all directly related to string theory. This has several consequences, for...

Hawking and Hartle proposed a well-known model which postulated a sum over all possible histories considering all compact euclidean metrics to explain the origin of the universe (this is called the No Boundary model). I was wondering whether there is any model or theory (related to cosmology)...

Some physicists (like John A Wheeler, Holger B Nielsen or Ilya Prigogine) have proposed that all the laws of physics (including the most fundamental ones) emerged from a primordial chaos (for example, in the case of Wheeler, he proposed that laws of physics emerged from an initial random and...

Are there any models, theories or physicists who propose that the fundamental laws of nature come from the initial conditions? Are there any physicists who propose that the most fundamental laws of physics emerged from initial conditions at the origin of the universe? And according to this view...

Gerd Binnig, Nobel laureate in physics in 1986, proposed in his article "The fractal structure of evolution" [1] that everything in the universe, including its laws, had changed and became what we have got today through a process which mixes some concepts from darwinian evolution and fractal...

Physicist John A Wheeler proposed the "Principle of mutability" which said that it could be the case that the universe would eventually shrink in a "Big Crunch" and the be re-born in another Big Bang. He proposed that the laws of physics (even the considered most fundamental ones) would change...

Is there any version of string theory or cosmological inflation that allows the most fundamental laws and constants change between universes? String Theory and Cosmological Inflation are two theories or models that allow multiple universes to exist. Laws and constants of physics could change...

Summary: Could different outcomes have different physics in Wigner's friend? Physicist Eugene Wigner said that consciousness was fundamental for physics and that laws of physics existed because of it. He said that "consciousness can change the usual laws of physics" He also proposed the...

John's Barrow book "The Constants of Nature" in chapter 13, he talks about a hypothetical multiverse composed of universes governed by other logics. Specifically, he talks about different approaches that physicists take when studying the multiverse, and he mentions a radical approach where even...

You may know I started a thread on this forum asking questions about the statement in General Relativity that "the laws of nature are the same in inertial frames". Guessing about the answers I got, I arrived in the following conclusion. I'd like to know whether these make sense & are correct or...

Considering the multiple universe view, if a measurement (or something else) makes visible which universe we are in, is it then also possible we find ourselves in one with (slightly) different laws of nature?

Hello, 1a) Generally, would anyone mind discussing what laws of nature (aka. physical laws, physical principles, scientific laws, etc.) are? 1b) Are they only to describe phenomena, i.e., interactions, behaviors, etc.? 1c) Or do any describe why certain entities are similar? Note: by...

The world seems to me to be rather arbitrary. I don 't know if people feel the way I do. Scientists apply for government grants to gather data, and conduct experiments. Some scientists look at the data, and write down equations. If those equations are sufficiently fundamental, then some...

Let’ say; “A” can see and measure a stone falls to the Earth let’s say 10 meter per 1 Earth-second. “B” lives at Mercury and can see the same thing. But “B” would do not see the exactly the same, because seen from “B’s” viewpoint time / distance is not the same as for “A”. Let us say...

This month at PI there will be a 3 day workshop on the Laws of Nature. As outsiders, what can we learn? http://www.perimeterinstitute.ca/en/Events/Laws_of_Nature/Laws_of_Nature%3A_Their_Nature_and_Knowability/ Smolin and Unger have a book in the works about this (time and the laws of nature)...

I'm new to studying physics. Are the laws of nature and the laws of physics synonymous with each other? Thanks!

The following is something i read, and attempt to reproduce. I made no claim for originality. For anyone that wants the title of the book, and page number. I will find it, and post it. ( I remember the author is an adjunt professor at rockefeller university) The universe U is a computer...

I think this is a recurring theme in many other threads, but haven't seen a poll. If we can get a large enough number of participants, would suggest to publish the results.

see: http://www.netscape.com/viewstory/2007/04/21/laws-of-nature-to-be-repealed/?url=http%3A%2F%2Fwww.glossynews.com%2Fartman%2Fpublish%2Flaws-of-nature-repealed-1291.shtml&frame=true and to think we all spent so much time studying the laws of nature only to have them repealed!

How do physicists do this?

That is perhaps the biggest 2 question for the whole of existence. Without it, there would be no sciences, no human, no anything...at all. Can the laws come into being without matter/universe? Can the universe come into being without the laws? (It is said that universe might come out of a...

The abundance of matter and antimatter implies the laws of nature are different for particles and antiparticles. This is shown in the way more b mesons than anti-b mesons decayed into kaons and pions - the weak force does not conserve charge/parity. But if CP symmetry is not conserved, does...
