NASA captures the "immortal god of death" of the universe

(NLDO) - Scientists have discovered unusual signals that resemble flashing lights, "crossing space" from where the universe began.

A team of astronomers from Stockholm University (Sweden) looked at data recorded by NASA's Hubble Space Telescope about faint galaxies born shortly after the Big Bang event that gave birth to the universe and noticed an unusual phenomenon.

These are galaxies that belonged to the early universe about 13 billion years ago.

These ancient galaxies were located approximately 13 billion light-years from where Earth exists today, and the light that makes up their images takes a similar amount of time to reach telescopes.

This inadvertently gives us a glimpse into the past and a glimpse into what happened when the universe was young.

In this case, the strange signals Hubble picked up could help explain the puzzle: Did the galaxies come first, or did the monster black holes?

According to the authors, the unusual signals in the nuclei of these galaxies are their supermassive black holes, a type of black hole known as a monster black hole, but much more terrifying than the monster at the center of our galaxy.

They are the largest black holes, millions or billions of times more massive than the Sun, that act as rips in space-time that forever swallow anything that passes nearby.

They are like sleeping dragons, not pulling matter continuously but only waking up and becoming active whenever something happens to pass by.

Each time they wake up to "feed", they light up like a lighthouse and then temporarily turn off. This is what causes the strange flickering light that Hubble recorded.

In the study published in the scientific journal The Astrophysical Journal Letters, the team of authors said they did a thorough review and realized that there are more of these black holes than previously thought.

Many of these objects appear to be larger than the initial masses scientists once thought they could attain in the early universe, suggesting they must have been very large when they formed or evolved rapidly.

The authors suggest that this size and prevalence suggests that black holes – the nuclei of galaxies – existed before the first galaxies formed.

They may have formed from the collapse of massive, primordial stars in the first billion years of cosmic time.

It was a type of star that was extremely massive, extremely hot, and short-lived, enough to create a large black hole when it died, not the tiny stellar-mass black holes of today.

Alternatively, they can also form directly from collapsing gas clouds, the mergers of massive stars.

Another interesting scenario is that they are the result of a merger of a type of primordial black hole, formed just seconds after the Big Bang.
