Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.

Sep 24, 2016 · 1. Dark matter. Galaxies rotate too quickly for their visible matter. Earth whirls around the sun at a speed determined by its distance, the sun's mass and gravity's strength, which is a universal constant of nature. You don't need general relativity to work that out: Newton's old-school gravitation will do.

- Newton’s Laws of Motion: Sir Isaac Newton’s laws of motion laid the foundation for classical mechanics and our understanding of motion: Newton’s First Law (Law of Inertia): An object at rest remains at rest, and an object in motion continues to move at a constant velocity unless acted upon by an external force.
- Law of Universal Gravitation: Newton’s genius extended to celestial mechanics with the Law of Universal Gravitation, which states that every mass attracts every other mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
- Maxwell’s Equations: James Clerk Maxwell unified electricity and magnetism with a set of four equations known as Maxwell’s Equations. These equations describe the behaviour of electric and magnetic fields and provide a foundation for the study of electromagnetism.
- Einstein’s Theory of Relativity: Albert Einstein introduced two groundbreaking theories: Special Theory of Relativity: This theory, encapsulated in the famous equation E=mc², revolutionised our understanding of space and time.

Apr 30, 2024 · This is a fascinating paper that sets out many of the biggest problems in physics in a way that largely avoids verbosity and so is easily accessible. There is another problem that this paper perfectly demonstrates but fails to mention explicitly — the gender bias in physics. A quick look at the list of authors makes this bias all too clear ...
