The End of the Dark Universe?

Please excuse me for being excited, but this hasn’t happened for more than four decades: Physicists have found a new approach to solving a problem which is almost a century old—how to combine quantum physics with gravity. The new idea comes from Johnathan Oppenheim, a professor of quantum theory at University College London, and he has dubbed it “Post-Quantum Gravity.” I wrote about his new proposal in Nautilus last month. 

Now Oppenheim and his collaborators are saying that their idea doesn’t just reconcile quantum physics and gravity, it also explains dark matter and dark energy. “Folks, something seems to be happening,” Oppenheim on X (formerly known as Twitter), sharing his research. “We show that our theory of gravity … can explain the expansion of the universe and galactic rotation without dark matter or dark energy.”The problem that Oppenheim set out to
