Wormholes can bend light like black holes – and that could be the key to finding them

If wormholes exist, they could magnify the light of distant objects up to 100,000 times — and that may be the key to finding them, according to research published Jan. 19 in the journal Physical Review D (opens in a new tab).

The Wormhole they are theoretical funnel-shaped portals through which matter (or perhaps spacecraft) could travel long distances. To imagine a wormhole, suppose the entire universe was a sheet of paper. If your starting point was a dot at the top of the sheet and your destination was a dot at the bottom of the sheet, the wormhole would appear if you folded that sheet of paper so that the two dots met. You could cross the entire sheet at once, rather than traveling the entire length of the sheet.
