New research suggests that the universe is filled with particles capable of traveling faster than light, LiveScience reports — and that this scenario holds up as a potentially "viable alternative" to our current cosmological model.
The idea is a little far-fetched, sure, but it's worth hearing out. These hypothetical particles, known as tachyons, aren't likely to be real — but they're not some hokey bit of sci-fi, either. The potential for their existence is something physicists have been giving serious thought for decades, raising fundamental questions about the nature of causality.
As detailed in a yet-to-be-peer-reviewed study, the researchers posit that tachyons are what make up dark matter, an unobservable — and despite being widely considered to exist by scientists, technically hypothetical — substance that is thought to account for around 85 percent of all matter in the universe.
