The end of the Universe, as we might imagine it, won’t come with the expected bang. Most cosmic features will slowly start to fizzle as their temperatures fade to zero. If you want a better picture, imagine a sad, cold, and lonely place. At least, that’s what Matt Caplan, a theoretical physicist, predicts things. Other scientists believe all will be dark as the Universe comes to an end, something known as “heat death.”
Recent theoretical work realized by Caplan states that many white dwarfs might explode in a supernova in the very distant far future, long after everything in the Universe has found its end and gone quiet. Here is what you need to know.
Predictions of the Last Supernova Show Intriguing Scenario of the Universe
Now, in the Universe, the tragic death of massive stars in supernova explosions occurs when internal nuclear reactions generate iron in the core. The iron is tricky because stars can’t burn it. It could gather, however, like poison, bringing the star’s tragic death. Smaller stars, on the other hand, tend to find their end with a bit more dignity. They shrink and turn into white dwarfs when they die.
Theoretical physicist Matt Caplan stated: “As white dwarfs cool down over the next few trillion years, they’ll grow dimmer, eventually freeze solid, and become ‘black dwarf’ stars that no longer shine.” But even if they become cold, that doesn’t mean the nuclear reactions stop.
Caplan explained how the fusion occurs even at zero temperatures. He also noted this thing is the key to turning black dwarfs into iron and triggering a supernova.
According to Caplan’s calculations, the first “black dwarf supernova” will happen approximately 10 to the 1100th years, and not all of them will explode. He said: “[…] it’s like saying the word trillion almost a hundred times.”
Moreover, the theoretical physicist predicted that the most massive black dwarfs would explode first. They’ll be followed by progressively less massive stars until there is nothing left. And at that point, well, we can say that the Universe might truly be dead and silent.
