Scientists Discover the Universe Could End Sooner Than We Ever Expected

According to Hawking’s Radiation theory, black holes are not permanent and will evaporate over time. It states that black holes, as they emit more radiation, lose a substantial amount of mass, so that billions and trillions of years later, they will probably completely evaporate.

Now, how is it related to the end of the universe? Well, think about this: what if not only black holes but also all other celestial bodies in the universe evaporate and lose their mass? In the event that this theory is right, then the whole universe will end sooner than expected by the gradual decay of all matter and energy. Let’s explore how his theory works.

A Revised Cosmic Timeline

Recent research from Radboud University in the Netherlands suggests that our current universe may end sooner than our scientists have previously predicted. There are some models that say that the universe may end in approximately 10^1,100 years via heat.

However, the new calculations done with the help of Hawking radiation are about 10^78 years. That is a very huge exponential difference, which equates to the universe ending a lot faster than we ever realized. The new theory is based on the assumption that the Hawking radiation holds true for all matter and energy in the galaxies. That they will all gradually decay and lose mass as they emit radiation.

So, our planet and sun, even the largest and smallest celestial bodies like white dwarfs and neutron stars, will soon just be gone after trillions and trillions of years.

Hawking Radiation and Cosmic Decay

Turns Out Universe Will Evaporate Much Sooner Than We Thought

Stephen W. Hawking’s theory that subatomic particles are escaping the event horizon of black holes or naturally appearing near it suggests that black holes are losing mass. Event horizon are black holes’ point of no return as everything gets suck into it. Not even light will be able to escape them, as they all achieved singularity in the middle.

If black holes really emit radiation that leads to their loss of mass, a generally accepted conclusion because of the naturally appearing subatomic particles in the event horizon, then it can be the reason for their eventual death.

Scientists build upon this existing theory and did the new calculations, where all cosmic objects also lose mass and energy, resulting in our whole universe slowly fading away. All of this challenges the notion that we have an ever-expanding eternal cosmos.

Implications for the Universe’s Fate

The revised timeline of when our universe will end changes a lot for our current understanding of cosmic history and evolution. It suggests that the lifespan of our universe is shorter than expected, but even that mentioned timeline is still trillions of times longer than the whole existence of our universe.

This means that relative to when the whole universe is predicted to die, it is still in its very early stages. Its age is almost like a baby compared to the predicted cosmic timeline, should it live its whole lifespan. So, is human existence really just so minuscule that it won’t even matter in the grandest scheme of all things? No one knows the answer, but we do know that it looks like we existed early in our universe, respective of when it was born and will die.

Ongoing Research and Observations

There is one big black horse that we have not talked about yet, and that is the existence of dark energy, which is responsible for causing the universe to expand at an accelerating rate. The longer time passes for us, the bigger our universe will be. Scientists would need to continue to research to know more about them and what roles they will play when it comes to the universe’s extinction.

There are also theories that involve the dark energy called the “Big Crunch” and the “Big Rip”. The Big Rip theory suggests that the universe will just continue to expand, eventually tearing itself and everything in it apart, down to the atoms and space-time continuum. While the Big Crunch theory thinks the expansion will reverse and we will be suck into the middle into a singularity.

Author's Final Thoughts

How our universe was born and is thought to die is one of the most interesting topics to create a theory about. At the end of the day, those are just theories whose existence is based on our current understanding of physics and the laws of the universe, which could very well be wrong.
