Summary:
Everything that exists consists of "matter", particles, science says.
1.1.1-1  Most people in the Western world believe that the world consists of "matter", particles that weave together into atoms and molecules - which in turn bind together in patterns and form larger shapes such as grains of sand, rocks, water droplets, clouds, plants, animals and humans. . Globes, suns, galaxies and the entire universe have been created in the same way.

1.1.1-2  Everything that exists consists of "matter", particles, science says.

1.1.1-3  The matter in the universe originated in an extreme "explosion" for approx. 13.8 billion years ago. What created the explosion and where the substance was previously, is an unanswered question.

1.1.1-4  And what is matter? Physics thus operates with the term "particles"; electrons, protons, neutrinos, photons, etc. There are approx. thirty different types of elementary particles. "Elementary"means that they can not be divided into even smaller parts.

1.1.1-5  Between the particles there is nothing, in the material sense. Substance consists mostly of nothing. If we remove the void between all the particles that make up the bodies of all mankind, they would fit in a sugar cube, an eerily compact and heavy piece of sugar.

1.1.1-6  What are particles? The answer is world famous and was given by Albert Einstein in 1905. Particles are energy. The equation is known as E = mc2, where E is the amount of energy (in joules), m is the mass of the substance (in grams) and c is the speed of light (about 300,000 kilometers per second).

1.1.1-7  Because the speed of light is a very large number, it means that if you manage to transform a tiny amount of mass, you will get an enormous amount of energy. This is what happens in atomic bombs and nuclear power plants. Small amounts of uranium are converted into energy.

1.1.1-8  The bomb that exploded over Hiroshima in 1945 turned 0.6 grams of uranium into an explosion that killed more than 100,000 people.
