'Strange' matter

'Normal' matter has atomic nuclei formed with 'up' and 'down'quarksplugin-autotooltip__plain plugin-autotooltip_bigQuarks

Following theoretical calculations, particle accelerator experiments in the 1970s confirmed that quarks are responsible for the internal structure of protons and neutrons. ( 3 quarks each, in different configurations, see :Electron / Quark charge balance).

. It's confirmed, however, that there are six types of quark - one of which is known as the 'strange' quark.

Multiple observations have shown that in isolation they spontaneously decay into 'up' quarks - in line with current theory.

In the mid 70s and early 80s, two nuclear physicists, Arnold Bodmer and Edward Witten proposed separately that it might be theoretically possible for stable matter to exist if its nuclei were built from roughly equal numbers of 'up', 'down' and 'strange' quarks.

This is the so-called Strange Matter Hypothesis.

Theoretical particles formed in this way have been given the name Strangelets - but, in theory, combinations of strange matter particles could be stable at any size, and it has been proposed that entire 'Neutron Stars' could be formed from strange matter.

To date, no strange matter has ever been observed - either in high-energy nuclear experiments or as a result of cosmic ray bombardment.

Nevertheless, many physicists agree on the theoretical possibility that it could exist.
