Tell your boss this one: “Space and time are different for me. YOU gotta adjust”

Can we draw that conclusion from an interesting recent study on elementary particles?
Here’s the explanation to give, when you are an hour late for work:
Before the Big Bang, space-time as we know it did not exist. So how was it born? The process of creating normal space-time from an earlier state dominated by quantum gravity has been studied for years by theorists at the Faculty of Physics, University of Warsaw. Recent analyses suggest a surprising conclusion: not all elementary particles are subject to the same space-time.
Several billion years ago, in the era soon after the Big Bang, the Universe was so dense and so hot that elementary particles felt the existence of gravity strongly. For decades, physicists around the world have been attempting to discover the laws of quantum gravity describing this phase of the evolution of the Universe.
“Particles with mass not only experience different space-times than photons do, but each sees its own private version of space-time depending on the direction it moves in. This finding really took us by surprise,” says PhD student Andrea Dapor.
By now, it will have occurred to him that if this quantum stuff catches on, he could use the same excuse for paying his bills late.
But be sure you don’t let him see this part of the story:
As observers studying the behaviour of elementary particles, we are classical, rather than quantum, systems and in a sense we are “outside” the particles’ world. It is not then important what each particle “experiences” of its space-time.
So, you are late and he is in arrears of his car payment after all.
But, if you don’t come in late again, by the time he figures that out, he’ll be busy checking up on someone else… 😉
