Earth may have hairy dark matter, says NASA

Washington: There may be long filaments of dark matter or "hair" on our Earth, suggests new research, adding further study is needed to unlock the mysteries of the nature of dark matter on Blue Marble.

Dark matter is an invisible, mysterious substance that makes up about 27 per cent of all matter and energy in the universe.

The regular matter, which makes up everything we can see around us, is only five per cent of the universe.

The rest is dark energy, a strange phenomenon associated with the acceleration of our expanding universe.

According to previous calculations and simulations performed in the last decade, dark matter forms "fine-grained streams" of particles that move at the same velocity and orbit galaxies such as ours.
