Not much is known about the mysterious stars that first lit up in the universe and were fuelled by dark matter.
The beginning of the universe and the birth of the stars
To understand this more clearly, we have to go long-long back in past, the time when the universe was quite young and looked completely different from what it looks today. The things were beginning to form and some stars were beginning to shine. Amidst all of this, the unknown dark matter ran berserk in young galaxies giving birth to the new breed of stars known as the dark stars. These dark or black stars are known to be very important celestial bodies but interestingly, we are not very sure if they do exist or not.
Why do we say that there is no evidence about their existence?
Dr Katherine Freeze, an astrophysicist at the University of Michigan has put forward a theory according to which dark stars might have disappeared into a black hole. She further explains that these dark stars are the seeds of the massive black holes that could be found in the heart of all galaxies. She further states that even a thing that can absorb light and bend space-time would be born out of something and that could be the much-speculated dark star. Now the question arises, how can a bright star have such a twisted dimension that it is called dark.
Major speculated difference between stars and dark stars
Scientists explain that stars comply with the rule of nuclear fusion which suggests that its constant pressure on its core results in energy that is radiated out. That makes up a perfect balance of inward attraction and outwards radiations. But dark stars are a different story altogether. They have not only helium and hydrogen working in them but also the unknown and mysterious dark matter. This dark matter is still a mystery as no one has ever seen or even detected it.
So, what is the theory?
As discussed earlier dark stars formed when the universe was still in its infancy. Now dark matter gave these dark stars their superpowers because of which they could radiate without nuclear fusion. This means they could shine brighter without any limit and a star of such high mass would ultimately collapse into a black hole.
These are just theories but with the launch of the James Webb Space Telescope, we are sure to uncover even more mysteries of our universe.
