Just yesterday I was having a discussion with a friend of mine about how the last two weeks seem to have flown by and my friend asked if there were ways we could slow time down a bit.
I suggested he could consider jumping into a black hole or accelerating himself to light speed and that the tools for these endeavours might be purchased cheaply via one of Amazon’s ‘Deals of the Day’.
Then an article pops up on Quanta Magazine that talks about the origins of time and the universe itself, particularly in relation to Hawking’s Shuttlecock Universe proposal.
When I look at what’s going on in the world I quite often have a downer on humanity in general and certain individuals specifically, but I think it’s astonishing that our thinking has advanced to the stage where we can consider the origins of an entire universe.
In their view, the only sensible contour is one that scans through real values (as opposed to imaginary values, which involve the square roots of negative numbers) for a variable called “lapse.” Lapse is essentially the height of each possible shuttlecock universe — the distance it takes to reach a certain diameter. Lacking a causal element, lapse is not quite our usual notion of time.
Get your head around that.
