JONATHAN OPPENHEIM likes the occasional flutter, however the object of his curiosity is a bit more rarefied than horse racing or the one-armed bandit. A quantum physicist at University College London, Oppenheim likes to make bets on the basic nature of actuality – and his newest issues space-time itself.
The two nice theories of physics are basically at odds. In one nook, you might have basic relativity, which says that gravity is the results of mass warping space-time, envisaged as a sort of stretchy sheet. In the opposite, there’s quantum principle, which explains the subatomic world and holds that every one matter and vitality is available in tiny, discrete chunks. Put them collectively and you can describe a lot of actuality. The solely downside is which you could’t put them collectively: the grainy arithmetic of quantum principle and the graceful description of space-time don’t mesh.
Most physicists reckon the answer is to “quantise” gravity, or to point out how space-time is available in tiny quanta, just like the three different forces of nature. In impact, which means tweaking basic relativity so it matches into the quantum mould, a job that has occupied researchers for nearly a century already. But Oppenheim wonders if this assumption is likely to be mistaken, which is why he made a 5000:1 wager that space-time isn’t finally quantum.
New Scientist caught up with him to search out out what makes him suppose typical knowledge is likely to be misguided right here, how the query is likely to be resolved with experiments – and why physicists love a superb wager.
