The mass of a fundamental particle is the inertia generated by its interaction with the Higgs field that permeates the Universe

Betelgeuse is a red giant star with a diameter of 1.2 billion km and it is the ninth brightest in the Milky Way. If it was placed where our Sun is, it would occupy all the space out to Jupiter

Every human being contains about a billion billion carbon atoms, each of which was created as a result of nuclear fusion reactions inside a star that later exploded expelling the carbon into clouds that later became part of planet Earth

The positively charged protons in the nucleus of an atom don’t fly apart because the strong nuclear force that binds them together is way stronger than the electromagnetic force that protons electrically repel each other with

As an object approaches the speed of light, the distance it travels contracts in the direction of its motion. For a photon traveling at the speed of light, from its perspective, the distance it travels is effectively zero

Jupiter’s mass is over 2.5 times the combined mass of the rest of the planets and all the moons in the Solar System

Superposition, entanglement, uncertainty, and non-locality are behaviours at the heart of quantum mechanics

Einstein’s Special Theory of Relativity establishes that two distant events experienced as simultaneous by one observer will not be simultaneous for another observer in a different frame of reference

Pluto was discovered in 1930. Pluto's orbital period around the Sun is about 248 Earth years. Pluto has covered 38.2% of its orbit since it was discovered

The radius of the observable universe with Earth at the centre is estimated to be about 46.5 billion light-years, containing a mass of ordinary matter estimated to be about 1.5 × 10⁵³ kg
