Yesterday afternoon went very quickly, despite not being very interesting. Now I'm familiar with time passing fast when I'm having fun, but this one is new on me.

So it got me thinking about time. Is time a constant? I mean, we have all these devices that measure it as such, and yet we can still lose track of it.

Again, it comes down to one of my favourite things, the perception of reality. So, if we percieve time as relative, then we make it effectively so, as far as we're concerned. The question arises, is it possible to do this deliberately, and if so, how?

The pragmatist in me also thinks that marketing a device that allowed people control over relative time, at least to a limited degree, would make me a small fortune...

Or, thinking about it, quantum mechanics. From that we get the Planck Time (on the smallest intervals, time is quantised - there is no physically meaningful interval shorter then about 10^-43 seconds - not too sure about the number, will have to look it up at some point).
Yes, there is a big question mark over how this fits in with General Relativity; is my Planck Timne your's? This is what we mean when we talk about the problems in formulating a Grand Unified Theory of physics - some bits of it flat-out contradict others.

This is the kind of physics I enjoy. Sadly we don't get to play with the quantum vacuum in Labs...
