University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010 that the early universe—which exploded from a single point and was very, very small at first—was one-dimensional before expanding to include two dimensions (like a plane) and then three (like the world in which we live today).
The theory, if valid, would address important problems in particle physics.
“What we’re proposing here is a shift in paradigm,” Stojkovic says. “Physicists have struggled with the same problems for 10, 20, 30 years, and straight-forward extensions of extensions of the existing ideas are unlikely to solve them.
“We have to take into account the possibility that something is systematically wrong with our ideas,” he says. “We need something radical and new, and this is something radical and new.”
In a paper published in Physical Review Letters, Stojkovic and Loyola Marymount University physicist Jonas Mureika describe a test that could prove or disprove the “vanishing dimensions” hypothesis.
Because it takes time for light and other waves to travel to Earth, telescopes peering out into space can, essentially, look back into time as they probe the universe’s outer reaches.
Gravitational waves can’t exist in one- or two-dimensional space. So Stojkovic and Mureika have reasoned that the Laser Interferometer Space Antenna (LISA), a planned international gravitational observatory, should not detect any gravitational waves emanating from the lower-dimensional epochs of the early universe.
Stojkovic says the theory of evolving dimensions represents a radical shift from the way we think about the cosmos—about how our universe came to be.
The core idea is that the dimensionality of space depends on the size of the space we’re observing, with smaller spaces associated with fewer dimensions. That means that a fourth dimension will open up—if it hasn’t already—as the universe continues to expand.
The theory also suggests that space has fewer dimensions at very high energies of the kind associated with the early, post-big bang universe.

does this mean everybody's given up on LIGO ever working?

Don't think there is any basis for you to say this.

when my grandad was in school, they told him without a doubt that the atom could not be split, that it was the only solid block of existence. You're only limiting yourself by thinking like this.
