WHY DOES THE UNIVERSE EXIST?
Back in the plague year of 1665–1666, Isaac Newton changed the scientific world, discovering the universal law of gravity and the mathematics of calculus. Now, in the plague year of 2020–2021, is history about to repeat itself? Stephen Wolfram thinks so. The British-born scientist, who lives in the US, claims he has found a route to a fundamental theory of physics that answers some of the biggest questions, such as what is space? What is time? And why does the Universe exist?
“To be fair, a lot of the work was done in 2019 and we were about to start speaking about it in March 2020, but everything locked down for COVID,” says Wolfram. “But it is true to say that we have made more progress towards finding a fundamental theory of physics than I dared believe was possible.”
Wolfram’s starting point was to ask: What is space? “Physicists don’t often ask this question,” he says. “They merely think of space as the backdrop against which the events of the Universe play out.”
According to Wolfram, space is made of a network of ‘nodes’, which are connected to each other. The nature of the connections – how each node is inked to nearby and faraway nodes – can create a space of any dimension. So if the number of nodes increases as the square of the distance from any given node – like the surface area of a
