For decades, we've dreamed of visiting other star systems. There's just one problem – they're so far away, with conventional spaceflight it would take tens of thousands of years to reach even the closest one.
Hypothetical travel times to Proxima Centauri, the nearest-known star to the Sun.
While pushing matter past the speed of light will always be a big no-no, spacetime itself has no such rule. In fact, the far reaches of the Universe are already stretching away faster than its light could ever hope to match.To bend a small bubble of space in a similar fashion for transport purposes, we'd need to solve relativity's equations to create a density of energy that's lower than the emptiness of space.
But what if it were possible to somehow achieve faster-than-light travel that keeps faith with Einstein's relativity without requiring any kinds of exotic physics that physicists have never seen?In the recent work, Lentz proposes one such way we might be able to do this, thanks to what he calls a new class of hyper-fastAccording to Lentz's theoretical calculations, these hyper-fast soliton solutions can exist...
