How to find a `` wormhole '' that can be warped beyond time and space
A `` wormhole '' is a tunnel in a space that directly connects one point in spacetime to another, but whether wormholes actually exist or not has been settled even after many years of discussions by physicists around the world. No. If such a wormhole existed, a paper was published that considered 'how to find a wormhole'.

How to spot a wormhole (if they exist)
Wormholes are 'tunnels that connect two points apart beyond space and time,' and often appear in science fiction works as beings that enable superspace-time warps. In reality, the existence of wormholes has been debated, and there is a theory that ' black holes that cannot escape light due to too strong gravity are connected to celestial bodies called white holes through wormholes.'
Dejan Stojkovic, a physicist at State University of New York at Buffalo in the United States, looks at the space called Sagittarius A * . It has long been pointed out that Sagittarius A *, about 26,000 light-years away from the Earth, has a supermassive black hole, 4.31 million times that of the Sun.
Since the existence of a wormhole requires extreme gravity conditions such as a super huge black hole, Stojkovic argues that this Sagittarius A * is a suitable place to search for a wormhole, Sagittarius A Checking the orbit of star
'If there are two stars on either side of the wormhole, the distortion of gravity will pass through the wormhole, and one star will be affected by the gravity of the opposite star. Sagittarius A * Assuming that there is a wormhole, the observed orbit of S2 will deviate from expectations. '
However, Stojkovic's claim is based on the assumption that 'if a wormhole exists'. 'Even if S2's orbit is actually misaligned, it does not prove the existence of a wormhole,' warned Stojkovic.
In addition, 'Even if a wormhole is actually found, it will not be something like drawn in science fiction works,' commented Stojkovic. 'Even if the wormhole could pass, very few people or spacecraft could pass. In reality, keeping the wormhole open requires a negative energy source. Does not know how to create negative energy, and it takes magic to create a stable and huge wormhole. '
