Since electromagnetism is so strong, multiple protons in the nucleus of any atom like Helium should repel each other very strongly. So how do they stay glued together?...Because of a force that is even stronger...

What is the origin of mass in the universe? Symmetry breaking. Symmetries in quantum mechanics result in 3 of the fundamental forces of nature - electromagnetic, weak and strong forces. However, the breaking of...

if you took a notebook, a plastic bottle, a toaster, and a glass container and burned them in a fire hot enough, around 10^31 degrees Celsius, all the particles and forces, would become one entity. This is what...

Is a theory of everything really possible? What makes us think it even exists? If we look at historical precedent, we can see that we have united seemingly completely unrelated forces and particles to a...

If you ask a physicist, what is at the core of physics, you will hear symmetry. What is symmetry? Gauge theory explained simply.



Symmetry is about actions that don't change anything. If we take an...

SUMMARY

How is mass and energy the same thing? What is mass really? If you weigh 80kg and are in a car moving 100km/hr, your energy is equal to about 30000 joules. But did you know that the energy you have standing...

Summary:

Everything you can see is made of up of the same fundamental particles. The best theory of fundamental particles and forces is the Standard model of particle physi

Introducing the four main forces of nature: gravity, electromagnetic force, weak and strong nuclear forces. Learn why they are fundamental to life on Earth. Physics - Forces - Learning Points. There are four fundamental forces of nature....

This nugget explains about the different types of forces.

If higher dimensions exist, they aren't what you think - Exploring Worlds Beyond Our Own

Once you start learning about modern physics, you start to hear about weird particles like quarks and muons and neutrinos. What are all these things? Why are there so many? How do we know they exist? What do they do? Within lies the...
