Non-Commutative Geometry Could Be Key To Quantum Gravity

Marco Frasca argues suggestively that the path to quantum gravity involves non-commutative geometry, a field that one of my most promising fellow students from college pursues professionally.

Hi!,
Sorry for being OT in this thread, but i'm really interested to know, about your opinion on the latest Irish aDNA, which also show steppe signals around ~2000 BC.

Do you think its too early for that R1b to be IE?.

Do you this goes along with this?.

Metallurgy arrived in Ireland with new people, generally known as the Bell Beaker People, from their characteristic pottery, in the shape of an inverted bell.[9] This was quite different from the finely made, round-bottomed pottery of the Neolithic. It is found, for example, at Ross Island, and associated with copper-mining there. It is thought by some scholars to be associated with the first appearance of Indo-Europeans in Europe (possibly Proto-Celtic),[10] though this theory is not universally accepted.

The Bronze Age began once copper was alloyed with tin to produce true Bronze artefacts, and this took place around 2000 BC, when some Ballybeg flat axes and associated metalwork were produced. The period preceding this, in which Lough Ravel and most Ballybeg axes were produced, and which is known as the Copper Age or Chalcolithic, commenced about 2500 BC.
