Exploding dark stars could be the answer to the universe’s accounting problem

The search continues for gloomy matter , the mysterious poppycock that have up the vast majority of all affair in the cosmos . Although nowadays they ’re most likely indiscernible subatomic particles , in the universe ’s beginnings they could have make super - volatile morose stars .

drab matter is , in brief , a huge radical of unnamed subject that has resisted all effort at direct signal detection , but must exist because we can evaluate its gravitational pull on steady subject . Dark matter account for likely about 85 % of all matter in the creation , and some idea put it as high-pitched as 98 % .

One of the unusual property about most nominee for the dark matter particle is that they are their own antiparticle , mean any two dark matter particles interacting in close proximity would annihilate each other in a matter / antimatter response . The universe is now big enough that this almost never would occur course , but when the universe was young and smaller , it was potential for saturnine matter molecule to accumulate together and forge the nucleus of dark stars .

Dark stars are something of a misnomer – unlike dark matter particles , they would be seeable and in reality quite smart because they would still mostly be made of regular matter . In fact , the dismal maven would have been the promising bodies in the unseasoned universe , as the perpetual annihilation of dark matter particles would release massive measure of vigor . The hotshot would bite through its dark matter nucleus very chop-chop , and then a novel nucleus of normal matter would form , start up the more intimate atomic fusion process inside the wiz . It ’s possible these former dark affair stars are still around in the modern universe .

Whether dark ace ever existed count on which suppositious particle makes up glowering affair . fit in to research led by Paolo Gondolo at the University of Utah , the axion is a principal contender for the dark matter particle , but it would n’t be able-bodied to form black principal . As such , if we ever observe sorry stars , that would probably extinguish the axion as the independent grim affair molecule . On the other hand , some of the Weakly Interacting Massive Particles , or WIMPs , would be staring to forge dark stars , particularly the supersymmetric photino .
