Recent photos taken from the Hubble telescope have given rise to a new understanding of how the mysterious substance ‘dark energy’ has helped the formation of our universe.
Dark energy exists between the galaxies, and although it is invisible it is actively pushing the different galaxies apart, and in so doing fighting the gravitational force of dark matter, by thinning the space that it occupies. This intergalactic struggle between dark energy and matter is like a giant wrestling match that seems to be somehow holding the universe together.
Invisible dark matter has been observed to bend light and to distort the images of planets and stars viewed through it. This is how scientists calculate the levels of dark matter in galaxies – the greater the warping the more dark matter. This effect is known as gravitational lensing.
It has been proposed that the existence of dark energy during the formation of the universe has caused the stunting of galaxy clusters, resulting in the universe as we know it being formed.
It is because of the existence of tools such as the Hubble telescope that scientists are able to make these radical discoveries and form such mind bending hypothesises. The Hubble is the single most powerful telescope that mankind has ever created.
