What happened to antimatter?

 
 

Particles come in pairs, which is why there should be an equal amount of matter and antimatter in the universe. Yet, scientists have not been able to detect any in the visible universe. Where is this missing antimatter? CERN scientist Rolf Landua returns to the seconds after the Big Bang to explain the disparity that allows humans to exist today.

 

 

Fusion energy explained with Hydrogen atom example

 
 

In this video we will understand how to or more nucleons merge or fuse together to create something more powerful and meaningful.
Let us first understand the meaning of the word NUCLEAR FUSION, Nuclear meaning the process which involves Nucleus and Fusion in English means two or more entities coming together or merging together to form one single entity.

 

Foiled proof

 
 

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute!

 

The basics of the boson

 
 

In 2012, scientists at CERN discovered evidence of the Higgs boson. The what? The Higgs boson is one of two types of fundamental particles and is a particular game-changer in the field of particle physics, proving how particles gain mass. Using the Socratic method, CERN scientists Dave Barney and Steve Goldfarb explain the exciting implications of the Higgs boson.

 

Dark matter: The matter we can't see

 
 

The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there’s more to it than that — a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy) and how we might go about detecting it.

 

How does an atom-smashing particle accelerator work?

 
 

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln explains how scientists harness the power of both electric and magnetic fields to smash atoms, eventually leading to major discoveries about the matter in our universe.

 

Ferrofluid - the magnetic liquid!

 
 

Materials scientist and Christmas Lecturer Mark Miodownik demonstrates some of the weird properties of ferrofluid. This liquid is literally ‘dripping with magnetism’, containing a suspension of ferromagnetic nanoparticles that make the liquid responsive to external magnetic fields, generating unusual patterns, shapes and motion.

 

String theory and the hidden structures of the universe

 
 

What is everything made of? Thus far, we can break everything in the universe down to a few very small elementary particles. But they fit into strange patterns that are not understood. Some scientists believe that this is because we can go deeper – perhaps to simple vibrating strings! At TEDYouth 2012, Clifford Johnson describes these ideas, along with the concept of string theory.
