Scientists say they've forged two miniscule simulated black holes and transmitted a message between them through what amounted to a space-time tunnel
Undated artwork provided by the California Institute of Technology in Pasadena, California depicts a quantum experiment that observes traversable wormhole behaviour.
"Experimentally, for me, I will tell you that it's very, very far away. People come to me and they ask me, 'Can you put your dog in the wormhole?' So, no," Spiropulu told reporters during a video briefing. "...That's a huge leap." "There's a difference between something being possible in principle and possible in reality," added physicist and study co-author Joseph Lykken of Fermilab, America's particle physics and accelerator laboratory.
Such wormholes are consistent with Einstein's theory of general relativity, which focuses on gravity, one of the fundamental forces in the universe. The term "wormhole" was coined by physicist John Wheeler in the 1950s.
