One of the world's most famous astrophysicists, Neil DeGrasse Tyson, is never silent about offering mind-bending ideas and illuminations regarding the mysteries of the cosmos. Recently, Tyson pointed toward what he believes to be the most dangerous substance in the universe: strange matter. This hypothetical substance, not yet discovered by scientists, is believed to possess properties so extreme and power-packed that it would instantly destabilize any normal matter that came into contact with it, changing it into forms impossible to comprehend, according to our understanding of physics today. The mere fact that such strange matter can exist has fascinated physicists. The horrific possibilities of something that may approach Earth can leave a physicist thinking forever.
What Is Strange Matter?
Theory behind strange matter is that the form of matter is thought to be ultra-stable residing deep in the hearts of the neutron stars, or as it correctly goes, in what turns out to come to be called the "strange stars". Neutron stars themselves are an event of extreme kinds. But when a massive star explodes in a supernova, the core collapses under such gravity that protons and electrons are squeezed together to make neutrons, forming a neutron star that is nearly pure neutrons. But scientists think that in the cores of the most massive neutron stars, these neutrons break down further into exotic particles called "strange quarks."
Quarks are the fundamental constituents of protons and neutrons. They have six "flavors": up, down, strange, charm, top, and bottom. In strange matter, quarks reassemble themselves into a highly compressed form that contains strange quarks. This renders the strange matter extremely dense and stable—perhaps even sturdier than any form of matter in the cosmos.
Why Strange Matter Is So Deadly
What makes strange matter so scarily alarming isn't its density or stability, but what it could theoretically do if it came into contact with regular matter. Tyson explained the terrifying hypothesis that strange matter, once in contact with regular atomic matter, would change it into more strange matter. This process, known as "strangelet conversion," would essentially rewrite the atomic structure of any matter that it touches, turning into a form that resembles that of the strange matter it is.
The result? A hypothetical "strange matter chain reaction." If even a small amount of strange matter were somehow to come into contact with Earth, it might potentially turn the whole planet, theoretically, into one mass of dense, lifeless strange matter. According to Tyson, this effect would be catastrophic-affectively turning everything in our atmospheric air to the earth's very ground into strange matter.
Is Strange Matter Just Science Fiction?
According to Tyson, the good news is that this strange matter is speculative and not observed directly. Although scientists have some theoretical reasons supporting the existence of such particles, they have not seen any strange matter or any strange stars yet. Another point is that a strangelet has to be extremely stable and powerful to initiate chain reaction, a property, scientists are not sure really exists in real strange matter.
Yet the theoretical risk is sufficiently grave to warrant consideration. Particle accelerators are the obvious exemplar of our timid ingenuity. Indeed, in 2008, as the LHC was turned on for the first time, some concerned that it might inadvertently generate a strangelet, or even a microscopic black hole. Quickly, physicists informed the world that any created strangelet would decay faster than almost anything else made in the laboratory, too swiftly to threaten harm.
Odd Stars: The Source of the Matter of Strange
So where would strange matter come from? Tyson and other physicists suggest that strange matter might be confined to the cores of strange stars, where pressure and density are extreme enough to allow for strange quark formation. These stars, if they exist, would have formed from the collapse of exceptionally massive stars, where neutron stars transform under intense pressure into an even more exotic state of matter.
Interestingly, weird stars sometimes may eject weird matter into space due to such collisions of stars. A collision between a neutron star or a strange star with any other star or with another strange star may, theoretically, expel strangelets into space. Such an event would be a very rare cosmic occurrence, but it is not impossible that, in the far-off future, strange matter can traverse galaxies and perhaps reach our solar system.
The Real Impact of Strange Matter on Earth
Strange matter is still safely theoretical, locked away in distant theories and rare cosmic conditions. Tyson reassures us that the chances of strange matter reaching Earth are extremely low. Even if a strangelet were to enter our solar system, it would need to withstand the harsh environment of space and survive any interactions with regular matter before it could pose a threat. Our solar system, in addition, is a tiny, protected space in a huge universe, and the possibility of a rogue strangelet hitting Earth is small.
But that said, the discussion by Tyson on strange matter raises interesting questions regarding the unknowns of our universe and the dangers lurking in the cosmos. He constantly remarks on the vastness of the universe and humility that inspires him, reminding one that for all of human advances, humanity has yet to scratch the surface of cosmic mysteries. In line with his concerns over strange matter is a general interest in possibilities and the danger that could be encountered through an understanding of the universe on its most basic levels.
What Can We Learn from Strange Matter?
It is extreme physics that challenges our perception of reality, and strange matter is what physicists are hoping to learn about. The fundamental forces of everything from atomic particles to whole galaxies are expected to be better understood by studying strange matter. It might help unlock answers about the early moments of the Big Bang, the nature of quarks, and even about the possibility of exotic forms of energy.
The strange matter concept, though quite science fiction-sounding, gives us an insight into the incredible diversity of matter and energy likely to exist beyond our current reach in work discussed by physicists like Tyson. Strange matter is a powerful reminder of the unknown. Even if this is only a far-fetched hypothesis, strange matter forces us to face the possibility that there are substances, forms of energy, and whole realms of physics that we have only begun to imagine.
A Chilling and Cautionary Tale
Neil DeGrasse Tyson cautions us of such esoteric matter with the same tenor of accessibility and excitement to the public; he is not instigating fear but awe-inspiring the public about complexities and wonders in the universe. Strange matter may prove to be the most perilous substance in the universe, but at the same time, it is one of the great unknowns that await us.
And with humanity continuing to push out into space
and probe ever deeper into the fabric of matter, Tyson reminds us all to
approach these discoveries with respect, curiosity, and caution. For the
universe may contain materials, forces, or dangers beyond our wildest
imagination, and that's precisely why science continues pressing forward,
driven by a mix of wonder and search for understanding.
