How Will Our Universe End? Big Crunch Theory

Everybody has heard of the Big Bang. Naturally, I'm referring to the Big Bang here, which is actually when everything began. That's nothing new; most people have heard of it. However, how well-versed are you in the Big Crunch?

Though there is still disagreement among scientists over how the cosmos came into being, the majority of them agree that it all started with a tremendous explosion of energy. Many ideas exist, including the Big Freeze and the Big Rip, but the Big Crunch is seen to be the most likely scenario.

That's probably not good news for those of you who tend to live billions of years and are class or bacon lovers. Now for the good news. There's a difficulty for those who devote their careers to answering problems like these, even though the math indicates that the Big Crunch is likely to occur. We still don't fully understand everything in the universe, and there are still certain unanswered questions that could determine our final destiny.

First, density and outward momentum seem to be playing a combined role in the universe's expansion. The more density there is in the universe, the more gravitational forces there are since density and gravity are directly correlated. By itself, this would imply that everything will ultimately converge on everything else, making the last Great Crunch inevitable.

The force of gravity would be more than sufficient to offset the initial outward momentum created by the Big Bang, even though there is no friction in space, and all stuff would effectively return to its original location. The issue with this, though, is that studies of the cosmos have revealed that things don't function as logically as we might anticipate. Galaxies are actually drifting apart at a faster rate than they appear to be expanding from one another in the furthest reaches. Although scientists are unsure of the cause of this phenomenon, they have given it a name: dark energy.

There are two possible outcomes as a result of this additional ingredient in the expansion of the cosmos. Either it will keep expanding indefinitely, pushing things apart until everything freezes, or there may yet be a Big Crunch. How much dark energy is genuinely present is what counts. Everything will keep growing if there is enough, which some scientists think might be the case. But in the event that there is insufficient, gravity will finally prevail once more and pull everything back together.

There are many who think that the seeming abundance of dark energy might be an indication that the Big Crunch is about to happen. In a 2015 article, however, it was proposed that the universe's present increasing rates of expansion are its final gasp, and that the shrinkage will start in tens of billions of years.

If there is not enough dark energy, the Big Crunch will happen. It would be a steady contraction, intensifying as galaxies get closer owing to gravity, in contrast to the cataclysmic Big Bang. Rising temperatures would lead stars to burst and things to evaporate over a period of around 100 billion years. Everything eventually collapses into atoms, and when matter compresses, mayhem results. Forecasts indicate that space-time will distort to the point of breaking, negating the significance of direction, time, and distance.

The end would have arrived long ago. We don't know enough about universal processes to be assured of the final result. One scenario in which all matter converges into an enormous black hole is called the Big Crunch. The consequences that follow a collapse are yet unknown; they might create a brand-new universe or continue cyclical expansions and contractions. It is possible for this behavior to recur, which suggests that we are in the middle of a continuous cycle. People who think they will live for billions of years don't need to consider such things.
