The universe 'will expand forever', new Nasa study on 'dark energy' concludes - Telegraph

Space agency researchers used the Hubble Space Telescope to “narrow in” on what they believe comprises the energy, which pushes our universe apart at ever-increasing speed.

Discovered it in 1998, astronomers have been unable to say what the mysterious force is, except that it is invisible and makes up a “large chunk of our universe”, or 72 per cent of its size.

Almost a quarter, 24 per cent, is thought to be "dark matter", which is also mysterious but easier to study than dark energy because of its “gravitational influence”.

The rest of the universe, a mere four per cent, is made of “the stuff that makes up people, planets, stars and everything made up of atoms”.

Yes we are very insignificant.
