In one scenario, the cosmos could continue to expand forever, with all matter eventually disintegrating into energy in what's known as a "heat death," Caldwell said. Alternatively, gravity might cause the universe to re-collapse, creating a reverse Big Bang, called the Big Crunch.

How will the universe end? Eliot regarding the end of the world. But if you want a more definite response, you'll find that physicists have spent countless hours turning this question over in their minds, and have neatly fit the most plausible hypotheses into a few categories. In one scenario, the cosmos could continue to expand forever, with all matter eventually disintegrating into energy in what's known as a "heat death," Caldwell said. Alternatively, gravity might cause the universe to re-collapse, creating a reverse Big Bang, called the Big Crunch we'll explain this later. Or, there is the possibility that dark energy will cause the universe's expansion to accelerate faster and faster, evolving into a runaway process known as the Big Rip. Before discussing the universe's end, let's go into its birth.

Cosmology deals with the big questions of the universe, often the same questions that keep philosophers up at night. When did the universe begin? How did it start? Has the universe always been expanding? For the record, the answers are: about

The "most precise measurement" ever made recently suggested our Universe is expanding much faster than previously thought, casting doubts on earlier predictions and even calling into question Einstein's theory of general relativity. Just as the Universe started after a Big Bang , astronomers are now attempting to study this expansion to predict how the Universe will ultimately end. The rate of this expansion may eventually tear the Universe apart, forcing it to end in a Big Rip. Alternatively, the Universe could 'shrink', decrease or decay, effectively reversing the Big Bang and destroying the Universe in a Big Crunch.

The ultimate fate of the universe is a topic in physical cosmology , whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. Based on available observational evidence, deciding the fate and evolution of the universe have now become valid cosmological questions, being beyond the mostly untestable constraints of mythological or theological beliefs. Many possible dark futures have been predicted by rival scientific hypotheses, including that the universe might have existed for a finite and infinite duration, or towards explaining the manner and circumstances of its beginning. Observations made by Edwin Hubble during the ss found that galaxies appeared to be moving away from each other, leading to the currently accepted Big Bang theory. This suggests that the universe began very small and very dense about

By Jacob Aron. Observations of stars and galaxies indicate that the universe is expanding, and at an increasing rate. The acceleration is thought to be due to dark energy , mysterious stuff that permeates the entire universe. If the total amount of dark energy is increasing, the acceleration will also increase, eventually to the point where the very fabric of space-time tears itself apart and the cosmos pops out of existence. But could it happen sooner? The data involved nearby galaxies, supernovae and ripples in the density of matter known as baryon acoustic oscillations, all of which are used to measure dark energy. The team found that the earliest a big rip can occur is at 1.

Universal apocalypse: This is how all of creation could end

Science has outlined four ways that our universe could meet its doom. Don't panic, but our planet is doomed. It's just going to take a while. Roughly 6 billion years from now, the Earth will probably be vaporized when the dying Sun expands into a red giant and engulfs our planet. But the Earth is just one planet in the solar system, the Sun is just one of hundreds of billions of stars in the galaxy, and there are hundreds of billions of galaxies in the observable universe. What's in store for all of that? How does the universe end?

One of the furthest reaches of time we dare to predict is the end of the universe. No more matter, no more light, no more particles, no more nothing. We must be triumphant on the edge of nothingness as we look forth to the fate of the universe. The end of Earth, on the other hand, could come at any moment. Cataclysmic asteroids, gamma-ray bursts, close supernova blasts, a rogue black hole, and so on.
