Are there any theories in science or physics that you don't agree with? which one's and why?
You just asked people what they want to brag about being wrong about.You seem to support a false theory about the use of the apostrophe.Quote from: trevorjohnson32 on 10/03/2021 21:15:20Are there any theories in science or physics that you don't agree with? which one's and why?
Great!Now the OP is in the Right place where one can speak up freely about personal point of views that do not match up with the views of the masses in general.👍I DisAgree that the Universe is Infinite.👎Surely it is expanding beyond our comprehension...but Our InAbility to find the Edge can Not be ascertained to defining this is an edgeless universe.P.S. - Just bcoz every Fruit on the Table seems Spherical in nature does Not mean that the Fruit Plate cannot be Rectangular.💠
If the universe has walls, then what are the walls made of? I agree that its probably finite.
This goes back to my atomic pit theory.

It could be a hypersphere of finite diameter, where travelling in one direction long enough puts you back where you began (similar to how a plane can fly in a "straight" line around the Earth and arrive back at its starting point).
There are some reasons:It can't explain the diffraction results of vertically tilted as well as horizontally tilted appertures.It can't explain why single slit apperture produces similar diffraction-interference pattern as thin wire.
A first principle is a basic proposition or assumption that cannot be deduced from any other proposition or assumption. In philosophy, first principles are from First Cause[1] attitudes and taught by Aristotelians, and nuanced versions of first principles are referred to as postulates by Kantians.[2] In mathematics, first principles are referred to as axioms or postulates. In physics and other sciences, theoretical work is said to be from first principles, or ab initio, if it starts directly at the level of established science and does not make assumptions such as empirical model and parameter fitting.
In physics, Albert Einstein's 1905 theory of special relativity is derived from first principles now called the postulates of special relativity. Einstein's formulation only uses two postulates, though his derivation implies a few more assumptions.
"A scientific theory is an explanation of an aspect of the natural world and universe that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results."fromhttps://en.wikipedia.org/wiki/Scientific_theory

A theory can still be shown to be false

In science, a theory is superseded when a scientific consensus once widely accepted it, but current science considers it inadequate, incomplete, or debunked (i.e., wrong). Such labels do not cover protoscientific or fringe science theories that have never had broad support within the scientific community. Furthermore, superseded or obsolete theories exclude theories that were never widely accepted by the scientific community. Some theories that were only supported under specific political authorities, such as Lysenkoism, may also be described as obsolete or superseded.Some theories have been discovered to be incomplete or not hold precisely, but remain in use as practical approximations. For example, all of Newtonian physics is satisfactory for most purposes, and so is widely used except at velocities that are a significant fraction of the speed of light. It is also simpler than relativistic mechanics and so is usually taught in schools. Another case is the belief that the Earth is approximately flat. For centuries, people have known that a flat Earth model produces errors in long-distance calculations, but considering local-scale areas as flat for the purposes of mapping and surveying does not introduce significant errors.In some cases, a theory or idea is found baseless and is simply discarded. For example, the phlogiston theory was entirely replaced by the quite different concept of energy and related laws. In other cases an existing theory is replaced by a new theory that retains significant elements of the earlier theory; in these cases, the older theory is often still useful for many purposes, and may be more easily understood than the complete theory and lead to simpler calculations. An example of this is the use of Newtonian physics, which differs from the currently accepted relativistic physics by a factor that is negligibly small at velocities much lower than that of light.
