Most of our universe is missing! What can the Matter Be

by Andy Fleming

Now, it’s an embarrassment of gargantuan proportions that lies at the heart of modern physics, a kind of cosmic elephant in the room. Put simply, physicists realise that when we look out 13.7 billion light years across the visible universe with our telescopes, whether at visible, infrared, gamma ray or x-ray wavelengths, we are only seeing a tiny proportion of all that there is. Modern physics and its key theories of quantum mechanics and general relativity, which have successfully provided us with everything from iPods to GPS systems, simply doesn’t have a clue as to what makes up 96% of the universe.

This is made up of atoms and their constituent parts – and includes stars, planets and intergalactic dust. Einstein said that mass and energy are equivalent, and since the late 1990s astronomers and cosmologists have found that a staggering 73% of the universe is made of something called Dark Energy, which reveals itself by an anti-gravitational force.

It turns out that the expanding universe as first revealed by Edwin Hubble isn’t just expanding at a linear rate; the expansion is accelerating. One day in the far and distant future, cosmologists will no longer see galaxies outside our own cluster – they’ll simply be over the cosmic horizon, too far away for light to have had enough time to travel to Earth. For now, though, we have little idea as to what Dark Energy actually is.

We may have rather more success in identifying Dark Matter, first postulated by astronomer Fritz Zwicky in 1934 to account for the ‘missing mass’ needed to sustain the orbital velocities of galaxies in clusters. Subsequently, other observations have indicated the presence of Dark Matter in the universe, including the gravitational lensing of background objects by galaxy clusters such as the Bullet Cluster, and the temperature distribution of hot gas in galaxies and clusters of galaxies. It is believed that most Dark Matter, by its very nature, does not consist of atoms. It doesn’t interact with electromagnetic radiation, and therefore we cannot detect it with our telescopes.

There are many speculative possibilities as to what Dark Matter may be, including a whole zoo of standard model or exotic particles including neutrinos and super-symmetrical particles, brown dwarf stars, rock, dust, or black holes.

Whatever Dark Matter turns out to be (and there are many experiments being conducted around the globe to detect it, including at the Large Hadron Collider at CERN and in at the ZEPLIN-III dark matter detectors at Cleveland Potash’s mine at Boulby, Whitby in the UK), we are likely to have an answer as to what this fundamental constituent of the universe is, long before that for Dark Energy. Whichever way you look at it, it’s an embarrassment for modern physics to only know what 4% of the universe is actually made of!

    I respect the fact that Mr. D’Antonio cannot reveal any specific details regarding the moon show he mentioned at the end of the extended podcast. But, I was curious if he could give the name of the show or what channel would be presenting it? Thanks!
