Introduction—Everything and Nothing: Nothing (03:07)


Physicist Jim Al-Khalili explains the difficulty of finding nothingness. The universe and much of the planet is filled with nothing.

Empty Space (07:34)

For 1,000 years, ristotle was responsible for the understanding of empty space. He thought nature would always try to stop the creation of empty space; people believed it was impossible.

Properties of Nothingness (09:46)

After Pascal and Torricelli created nothingness on Earth, scientists wanted to know what its properties were. They conducted experiments with numerous items in a vacuum. The vacuum prohibited sound waves but still allowed light waves.

Light in Empty Space (05:10)

Light always travels at the same speed and is not carried on aether as scientists once thought. After it was proven that light could travel through a vacuum, it started to have numerous participial uses in society.

Heisenberg's Uncertainty Principle (06:45)

At a fundamental level, nature is based on uncertainty. Al-Khalili uses a non-mathematical analogy to explain the essence of the uncertainty principle.

Paul Dirac (09:30)

Dirac had a geometrical view of physics. He applied quantum physics and special relativity to the electron and described it mathematically.

Anti-Matter (04:41)

Dirac's equations seemed to show there was another type of particle that had yet to be discovered. He called it an anti-electron, meaning that all matter had anti-matter.

Willis Lamb's Experiment (04:07)

Lamb created an experiment to study how parts of an atom react in a vacuum. A laser can detect movement in an electron, which would not happen if the vacuum was truly filled with nothing.

Creation of the Universe (08:07)

Today's theories suggest that the universe initially expanded rapidly. When it was created, it was smaller than the size of a single atom and followed the rules of quantum physics. Experts explain the image of the first light that was released after the Big Bang.

Part two of the series Everything and Nothing deals with science at the very limits of human perception, where the deepest mysteries of the universe lie. Professor Al-Khalili sets out to answer one very simple question: What is nothing? His journey ends with perhaps the most profound insight about reality that humanity has made. Everything came from nothing.
