Black holes: Scientist says black holes could potentially make time travel possible
Time travel is generally known to be impossible, and a concept that only exists in fiction and pop culture. However, one scientist says that black holes may actually make it possible.
What lies beyond a black hole appears to be just as mysterious as the black hole itself, but according to Atharva Palshetkar of the CTES College in Mumbai, India, black holes may provide a means of time travel if one were to fall in. According to Palshetkar, if a spacecraft were to approach a black hole, time will affect the spacecraft in itself, and the closer it gets to the black hole, the slower time will get.
Palshetkar also explained that if one were to witness someone falling through a black hole, they would see the person falling into it slower and slower. “Taking weeks, years, and even decades, until you reach the point where light can’t escape the black hole’s event horizon,” said Palshetkar via Quora. The witness would only be able to see the spacecraft stuck at the event horizon until it shifts and eventually disappears.
From the perspective of the person falling into the black hole, however, according to Palshetkar, everything they will see outside will speed up. Everything that would take years or decades would pass by in minutes or hours. Billions of years will also pass by in a fraction of the time.
However, Palshetkar’s theory poses several errors. The first of which is that no one could be able to survive falling into a black hole because of a process called “spaghettification” due to the extreme gravitational pull of a black hole. Another error is that simply traveling towards a black hole, the nearest of which is 6,523 light-years away from Earth, will take a very long time. It should be noted that one light-year is equivalent to 5.88 trillion miles.
Meanwhile, in other news, residents in Florida, US witnessed a fireball light up its night skies. Many reports were then sent to the International Meteor Organization recalling the details of the fireball.
Many expressed their amazement and how they have never seen anything like it. Others expressed how they were lucky to witness such a phenomenon take place.
