El Reto

The universe is the name that we use to describe the collection of all the things that exist in space. It is made of many millions of millions of stars and planets and enormous clouds of gas separated by a gigantic empty space which is called the universe.

El Resultado

Astronomers can use telescopes to look at very distant galaxies. This is how they see what the universe looked like a long time ago. This is because the light from distant parts of the universe takes a very long time to reach us. From these observations, it seems the physical laws and constants of the universe have not changed.

El Inicio

Many people in history had ideas to explain the universe. Most early models had the Earth at the centre of the Universe. Some ancient Greeks thought that the Universe has infinite space and has existed forever. They thought it had a set of spheres which corresponded to the fixed stars, the Sun and various planets. The spheres circled about a spherical but unmoving Earth.

La Estrategia

Over the centuries, better observations and better ideas of gravity led to Copernicus's Sun-centred model. This was hugely controversial at the time, and was fought long and hard by authorities of the Christian church (see Giordano Bruno and Galileo).

Definición de la Marca

The invention of the telescope in the Netherlands, 1608, was a milestone in astronomy. By the mid-19th century, they were good enough for other galaxies to be distinguished. The modern optical (uses visible light) telescope is still more advanced. Meanwhile, the Newtonian dynamics (equations) showed how the Solar System worked.
