Scientists have been speculating about wormholes – bridges between far off points in spacetime, for quite a few years now. In theory, these wormholes can serve as shortcuts for those travelling through space and time.
So it is only fit that the concept has found itself being the narrative of several movies and shows, the recent example being DARK. New research by scientists now hint that such wormholes might not be restricted to theory for long.
A new research paper, published in the Monthly Notices of the Royal Society, suggests that some of these wormholes may exist at the centre of some very bright galaxies. Authored by Russian astronomers, the paper also proposes some observations to find these wormholes, thus proving their existence.
This hunting technique for wormholes is based on “what would happen if matter coming out of one side of the wormhole collided with matter that was falling in,” explains a report by The Conversation. In their research, astronomers calculate that the crash would lead to a giant display of gamma rays, which can eventually be observed by humans through space telescopes.
Scientists say that the radiation in this case would be very different from the one emitted by black holes. It would be in the form of a giant sphere, while those observed from a black hole are fewer and in the form of a jet. “This radiation has a distinctive spectrum much different from those of jets or accretion disks of AGNs. An observation of such radiation would serve as evidence of the existence of wormholes,” a summary of the paper reads.
Travelling through space time
The study considers a traversable wormhole, meaning one through which humans can possibly travel through space time. However, it speculates that such a travel can only be possible through wormholes located far away from an active galactic centre. Else, the high temperature would practically burn anything that tries to go through.
Such wormholes also need to be sufficiently large. For the time of travel through one, it must also be kept open against the force of gravity. This can possibly be done through “negative energy”, proposes TC report. Negative energy is the backbone of the speculative theories around wormholes, as it is considered to be gravitationally repulsive and hence helps prevent wormholes from collapsing under their own, massive gravity.
Wormholes have long held the fascination of many scientists. A travel through space and time could change the very fabric of several known aspects of physics, confirming some, discarding others. But before we reach that stage, the search for wormholes continues, now at a faster pace.
