Scientists decode 'death' of our universe, say it will one day collapse and end with a 'big crunch'

Scientists, after decoding different facets of how Earth and the Sun will eventually cease to exist, have now tried to understand how the universe will die.

The new observation hints that dark energy is likely getting weaker across the universe and so it will end with a "big crunch".

The "big crunch" event is most likely to occur after millions of years but experts working on a Dark Energy Spectroscopic vision warned that the world's future appears bleak.

According to the research, since the universe is rapidly expanding, it is likely to weaken the energy which forms the atoms.

Universe will slowly grind to a halt and collapse

Scientists created one of the deepestmapsof the cosmos usingdata collected by theDark Energy Spectroscopic Instrument (DESI)in just its first year.

Cosmologist at the Universidad ECCI in Columbia and former DESI team member, Luz Angela Garcia Penaloza confirmed that the dark energy's effect is "decreasing" over time.

Scientists have described this decrease in dark energy as the "big crunch". This observation of the cosmos implies that the universe will grind to a halt slowly and eventually collapse.

Speaking to Space.com, Luz said, "If what the first year of DESI results suggests is true, then the accelerated expansion of the universe will cease and eventually reverse, and the universe could begin drawing together under the influence of gravity."

"This could eventually lead to the universe ending in a 'Big Crunch' scenario," he added. Meanwhile, an expert said that the big crunch will be "initially" harmless, however, it will eventually develop into a life-killing experience.

Pennsylvania State University's Martin Bojowald said, "The collapse initially would just be very harmless; the density of the universe would increase, but very slowly. But at some time, the collapse would lead to densities the same size as the Big Bang."

Till now, scientists have not been able to draw an entire picture of how the "big crunch" will appear.

According to Bojowald, the scientists are on the verge of comprehending the visual size of the "big crunch".

Explaining the magnitude of the "big crunch", Luz said, "We're going to have a very complementary vision of the universe from two completely different missions."

He said, "They are going to give us a completely brand new vision of how the universe is behaving and how dark energy is shaping the larger scale universal structure."
