In the universe there is a kind of ‘time machine’ that can bend both space and time
According to SciTech Daily, a team of scientists led by Dr. Benjamin Thomas from the University of Texas at Austin (USA), used data from the Hobby-Eberly Telescope (HET) at the McDonald Observatory to answer the question. the years-long controversial mystery of supernovas. .
When an exploding star is discovered, scientists will see how its light changes over time. One by one, starting from flickering, lightening, then peaking, and then starting to fade. By recording time on a light graph, they were able to infer the physical characteristics of the system.
A supernova (an exploding star) is inherently a moment of sudden explosion. The researchers should have seen the moment of maximum light at the instant of the explosion. But instead, the light emitted in the explosion loomed like a ghost.
In a paper published in the Astrophysical Journal, the team demonstrated that the “ghost of light” before the explosion was indeed a space-time phenomenon.

Dr. Thomas said his team had long observed light emitted by supernovae. At the time of the explosion, the space and time surrounding the supernova was warped, causing a flickering “ghost of light” instead of the immediate peak of glare. .
2014C once again helps demonstrate that supernova has enough power to “bend” space and time, causing people to see images as if sent through a time machine. Apparently, the matter-generated light emitted by the supernova was so strong that it made the jump to Earth faster than normal light.
Not all supernovas are capable of creating space-time effects. Powerful supernovas like 2014C are classified as type IB, contain a lot of hydrogen, once known as “light-bending” matter that behaves much more strangely than other matter.
