Over the billion-plus years, the Milky Way galaxy has a graveyard of stellar remains after they end their life cycles to later exist in a cosmic limbo. In the 13.6-billion-year history of the Milky Way, the life, birth, and death of stars in space were accompanied by supernova blasts, but where did these stellar corpses disappear to?
Galactic Underworld
On August 26, a study published in the Monthly Notices of the Royal Astronomical Society proposed what has happened to these solar hulks.
They based their assumptions on a computer model that predicted where stars would be in the early galaxy, long before the galactic spiral existed, and even further back in time.
Next, the model was fast-forwarded to reveal where the remnants of these stars are lurking like cosmic phantoms in the dark, reported Live Science.
What was revealed is something like a galactic underworld where the corpses of black holes and neutron stars are the densest bodies, but the home galaxy is full of these cosmic zombies.
Call it limbo, but its mass is roughly three times that of the spiral galaxy, an unknown place in space where countless dead stars have existed after their last explosions sent them to a graveyard of sorts.
According to the study's lead author, David Sweeney of Sydney University, all of the universe's 30% of objects are not in the Milky Way galaxy. They are in some unknown existence, like a cosmic limbo.
He added that supernovas erupting is not the same, and their remains are flung immensely fast, beyond comprehension, and more than human calculation.
Stellar Remains
The study looked at the two kinds of stellar remains after an explosion.
One solar mass will shed its material and leave its core, which is dense, and the other is a black hole that allows no light or matter to escape its gravitational pull.
Both are cosmic bodies that have spent their hydrogen and elements that end in the strongest explosions in existence that cause gravitational implosion leaving a mark on the fabric of space-time.
A dying star with a solar mass eight times that of our sun would produce a neutron star; however, if the solar mass is around 25 solar masses, a black hole would be formed in its place.
In the spirals of the Milky Way, these stellar remnants have been detected, but it is not enough because of the immeasurable time in which the galaxy exists.
Such remnants exist but are hard to find due to changes in the home galaxy over 13 billion years; the galactic netherworld is very irregular. A supernova is a superkick that can send a dead hulk of a star too far into the depths of the cosmos.
The researchers created a computer scenario to compensate for this unpredictability, as well as the reshaping of the Milky Way and a wide range of other factors.
Based on the model, the most stellar remnants are pushed to the galaxy center, where an immense black hole pulls everything close to it. Also, the last remains of stellar corpses are blasted all over the galactic spiral, which is not yet understood why they went there.
Like a limbo, this netherworld of the dead starts to reside and use 1% of the galactic mass like a revenant, it stays.The Milky Way galaxy is a graveyard where stellar remains are never left but linger like revenants in a strange cosmic limbo in the universe.
