Some physicists still aren't buying it.
Albert Einstein’s theory of general relativity is just over 100 years old, and so far it has predicted the interaction between celestial objects and the space-time field very well. There are a few troublesome spots, however, in which the theory of general relativity doesn’t agree with quantum mechanics. These gaps have confounded researchers for decades, and have sprouted a handful of hypotheses attempting to explain the dissonance.
Verlinde focuses on quantum interactions to explain the dissonance between general relativity and quantum theories. His theory has a long way to go before completion, but so far it has held up well and has made some strong arguments, particularly against the idea of dark matter.Physicists are painfully aware of the fact that spiral galaxies are spinning faster than they should be, given the amount of matter — and therefore, gravity — they contain.
The Hubble constant describes the observed accelerating expansion of the universe. This acceleration is unexplained, but has been attributed to “dark energy,” which Verlinde says can be used to explain away the idea of dark matter. “This possibility is intriguing, but as far as I’m aware, it’s not based on a precise model that is mathematically consistent,” Van Raamsdonk says. “Rather, he’s using his intuition to piece together a set of ideas and provide a story for how things might work. He is a very accomplished physicist, so I think his intuition is worth paying attention to.
“I have to sell my ideas to various audiences, not just to cosmologists and people that are dealing with dark matter in other ways, but also my string theory colleagues,” he says. “I think people are slowly starting to see the advantages of the logic of my reasoning.”
