Dark Matter: How much dark matter is there in the Milky Way – Why can’t we see it? | Science | News

Miss Lavender said: “Nobody knows what dark matter is but the current prevailing model is that is it ‘cold’, i.e. of low temperature and low energy, causing dark matter particles to move sluggishly and rarely, if ever, interact with normal matter except through gravity.”

Dark matter does not appear to emit or interact with electromagnetic radiation, rendering it virtually invisible to our detection methods.

In March 2019, particle physicists at the European Organization for Nuclear Research (CERN) told the Large Hadron Collider (LHC) could be the key to cracking the dark matter mystery.

British physicist Mark Williams: “There’s no point in postulating a theory, which cannot be tested. We’re scientists, not philosophers, so we have to make testable predictions.”
