Detecting FTL journey with LIGO – George’s Techblog
TL;DR: a warp journey will present up on a gravitational detector as a result of the area ship’s mass immediately disappears and later re-appears some place else.
There may be some attention-grabbing foundational research [ALC] into faster than light [FTL] journey, however by every little thing these theories inform us, the substances for such modes of transportation aren’t out there within the universe. FTL ought to be attainable as a result of the universe expands [EXP] at speeds higher than that of sunshine.
Since it’s unclear whether or not the fabric wanted for an FTL drive will ever be out there, funding analysis in that route may very well be a waste of sources, until synergies emerge. Within the spirit of respecting taxpayer’s cash, I feel FTL analysis ought to attempt to exploit – and generate – synergies with different fields of analysis.
FTL analysis may lie within the intersection of two such fields: the seek for extraterrestrial intelligence [SETI] and observation of gravitational waves [LIGO]. If FTL-capable civilisations exist on the market, their use of FTL know-how ought to produce observable interactions. Perhaps warp drives paint vivid orbits into the sky by emitting radiation or their space-bending drives disturb particles within the area ship’s path that emit radiation. However, since we don’t know the mechanism with which an alien FTL works, such direct observations is probably not attainable.
What we do know, nevertheless, is {that a} warp journey between A and B begins with a mass immediately disappearing from level A and showing typically later at level B. Altering/transferring lots produce gravitational waves and the journey ought to present up as two blips: one when the ship disappears from A and one when it re-appears at B. It’s conceivable that the mass is lowered (gas consumption) through the journey or that there’s a gravitational hint alongside the trail of the ship, however the begin and finish of the journey ought to present up as two distinct occasions. Assuming FTL-capable civilisations focus their populations in sure components of the galaxy, identical to we reside in cities, a spatial focus of these blips can be a great indication in direction of somebody having invented FTL.
