Researchers have found the initial visible proof linking black holes with dark energy.
The said study hints at the contradicting mass estimation model of black holes building up over a period of billions of years that does not agree with the assumptions of gas processes or mergers. But, on the other hand, is this mass growth of the black holes supporting theories, which predict that black holes composed of the vacuum energy, one of the possible outcomes as a result of compressing matter to the limits, without violating Einstein’s equation and nearly a singularity, what is also cosmologically linked.
The viewpoint stands after discounting singularities, and shows that the measured dark energy in our universe corresponds entirely to the total vacuum energy entropy of black holes formed at the end of the universe’s initial stars .
Duncan Farrah, the lead author of both studies and an astronomer at the University of Hawaii, stated, “We are essentially making two key points: after the original standard black hole models collapse the energy field becomes dark energy and this, is thought to be the first astrophysical origin of the dark energy”
He added, “This does not imply that others have not proposed origins for dark energy, but this is the first observational study where we are not introducing any new elements to the universe as a source of dark energy: The extent of this void, called the universal speed limit, limits the power of Einstein’s gravity theory for black holes.
The new findings could mean that we have to revise our black hole knowledge quite drastically if this analysis will be verified by the extended data.
Nine billion years ago
In the first study, the scientists were planning to exploit current black holes’ measurements to seek the new interaction of the cosmological origin.
Farrah’s expression of his interest in the project was enriched by the fact: “I was generally inquisitive in items contemplation and the reward after taking in mind the black hole model explanation.” He continued to state, “It is a very difficult one trying to directly observe a black hole when all they do is demolish and make things disappear into them and that is very hard to spot.”
As well, the studies over sufficiently-long time periods need to deal with multiple issues. In general, the time period that is studied is restricted to a few nano seconds or few decades which is very less compared to the duration that a black hole experiences over the entire lifetime of the universe. The difficulty of visualizing the changes of black holes through hundreds of millions years is another extremely hard thing to conceive of.
Tarlé expanded on the possibilities explaining, “which would require in first place to find a group of black holes and define their mass distribution billions of years ago. Also, once would need to know how the same group of black holes or their families are distributed nowadays and measure those quantities again. Such a demand is really impossible.”
Researchers found that galaxies’ composition was the key and that being able to tell whether many galaxies could contain a supermassive black hole was very difficult since many galaxies have lifetimes exceeding a few billion years and only a few of them hold a supermassive black hole.
“There isn’t actually any consensus on black holes in the galaxies that can be found back from the prior reading,” observed Sara Petty, a galaxy expert at NorthWest Research Associates and the co-author of the study. “With this in mind, we decided that by focusing our black holes only on elliptical galaxies that passively evolve, we would cite many unknown and brought confusion.”
Giant ellipticals lie at the ancient tail of the evolutionary process, and they play a leading role in the cosmic paradigm. Their shapes are evidence for how a galaxy condensed from clouds of gas and dust. They are enormous mass, 100 billion times of our Sun, which astronomers think they are the prototype of the collision of two or more galaxies.
Very little gas exists in between the stars in those galaxies which have already aged, thus they as a whole create very few new stars. Nonetheless, Tarlé underlined, “Black holes could not eat anything!”
The team could reason that the accretion patterns of black holes of the elliptical galaxies become difficult to account for by any other known process if they disregard galaxies that have not had any recent activity and a recent episode. Researchers inaugurated a survey which they used to examine the evolution of black hole mass of the center during the previous 9 billion years.
In this situation, nobody would expect that the accumulation of these black holes is unable to produce a great mass growth in black holes due to the embracing of only the accretion or merger. Nevertheless, non-active evolving elliptical galaxies may signal this phenomenon provided that nearby black holes gather gas from external galaxies by the ongoing universal expansion.
Unlocking black holes
Upon the process of the investigation, the group ventured into trying to ascertain black hole growth’s acceleration observed in the latter study only through cosmic coupling.
As per Prof. Kevin Croker, a co-author, theoretical astrophysicist at the University of Hawaii, a black hole that was coupled is similar to a rubber band which stretches alongside the universe in the same manner. By being elastic, its energy is enhanced like as this band stretches. In correspondence to the E = mc2 formula (Einstein’s), the mass and the energy are directly proportional, so we can observe an increase in mass as the result of black hole formation.
The amount by which the mass increases is a byproduct of power “k”, which is the coupling constant, chosen by the scientists.
As Croker explained, “the greater the rubber band retains the property of being pliable, the higher the energy it has when stretched. As a result, this can account for its stretching ability.”
One major obstacle that lies before the theory of cosmic coupling is the mass of the black holes in the initial study, which should be lesser than the magnitude that is required by the cosmological coupling in order to account for the growth of the universe. This is because the cosmological coupling comes into action as a result of the expansion of the universe and since the universe was considerably smaller as compared to today, the black holes grew to a lesser extent.
The subject of research in our team was 3 different types of the same galaxies, the brightness of which was 5 times greater for each galaxy observed compared to the luminous state they would reach at their present size. Out of the k cases, each one had k-3 inches.
Joel Weiner, a professor of mathematics at the University of Hawaii and Croker, a former graduate student, had succeeded in ascertaining this value for the ellipses encompassing the vacuum energy instead of the singularity already in 2017.
This discovery leads to a significant conclusion: These results arise simply from black hole dark energy measurements, counting for nearly a constant dark energy density in each and every universe if k = 3, proven by Croker and Weiner beforehand.
“Is it enough?” Tarlé wants to question himself. “Could we attribute black holes to be the ones with the dark age over eons to account for the 70% of the energy in the present universe?”
The turning of some of the stars, the collapsed old massive ones into black holes, provide many chances for those of us who want to calculate, using the cosmological coupling, number of the black holes and the growth rate of the black holes they generate based on the number of the massive stars that formed from the time of this Universe’s creation. A JWST study striking on the stars formation at an early stage has conformed to some models.
The scientists seem to be confident that this is a step in the right direction, providing further empirical evidence for theories of dark energy, and elaboration of ongoing experiments like the Dark Energy Survey and the Dark Energy Spectroscopic Instrument by physicists and astronomers in future to gain more insight into the phenomenon.
“In contrast to black hole decoupling, coupling if proved verifies that black holes remain entirely non-detached from our world, meaning well into the future they remain to play a key role in the universe’s evolution,” said the researcher.
Among the urgent problems that remain unsolved in contemporary physics is to find out whether dark energy is a content 70% , for the universe, of the universe. Since, the most recent observational data has revealed its nature, its widespread presence and the reason why it is so much more abundant than the other forms of energy in our universe accounting for 70% of it. We now have a clear picture of what is needed to develop a cure for this dreadful disease!
