From Paul Reeve
Thankfully, physicist Lee Smolin has concluded that time is not an illusion (20 April, p 30). Having read in previous issues of New Scientist that reality could be an illusion (29 September 2012, p 45), and that some cosmologists think we are simply holographic projections (23 July 2011, p 31) on a two-dimensional brane dominated by unseen dark energy and matter within an infinite multiverse – which itself is just part of a computer simulation by a massively advanced civilisation (29 September 2012, p 41), I – if indeed I exist – was a bit worried for a moment.
