2D Space Time

Technology Review: Why Spacetime On The Tiniest Scale May Be Two-Dimensional: The latest thinking about quantum gravity suggests that spacetime is two-dimensional on the smallest scale. .... nobody is quite sure whether the terms 'space' and 'time' have any reasonable meaning at this scale..... there is a growing number of indicators (evidence is too strong a word) that point to that conclusion...... recent work in loop quantum gravity, high temperature string theory, renormalization group analysis applied to general relativity and other areas of quantum gravity research, all hints at a two dimensional spacetime on the smallest scale. In most of these cases, the number of dimensions simply collapse in a process called spontaneous dimensional reduction as the scale reduces ..... one of time and one of space

This space time talk reminds me of when I was at a Science House MeetUp months and months back (Thank you FBI, I no longer show up for Science House MeetUps) and this super smart Indian guy was going on and on about ridiculously small structures. And I remember putting in my word to suggest just like we found nuclear energy at the nucleus level, perhaps there are stores of energy at even smaller scales.

James Jorasch who runs Science House later gently nudged me in the direction of algae. There is a lot of clean energy that can be tapped at the algae level, we don't have to go that small, he seemed to suggest.

Although this 2D space-time talk is quite speculative at this point.
