The Universe Will Eventually Vanish


It an age old question, how and when will the universe end. Scientists have outlined a test for “vanishing dimensions” hypothesis, which, if proven, would address major problems in particle physics.

Imagine a dark Universe with no stars, planets  or galaxies. In 100 billion years astronomers could be out of work because of nothing to observe. The Universe will fade away and if humans still exist, they will feel more lonely than ever. This gloomy picture of the future was presented Professor Brian P Schmidt, renowned astronomer and 2011 Nobel Prize winner in Physics.

“Human beings will look to an empty universe in 100 billion years, as all the galaxies will fade away except the Milky Way we live in,” said Schmidt, who attended the 28th General Assembly of the International Astronomical Union (IAU) in Beijing.

Professor Schmidt shared the 2011 Nobel Prize in physics with Saul Perlmutter and Adam Riess for providing evidence that the expansion of the universe is accelerating. Before their surprising discovery, it was commonly thought that the expansion of the universe was slowing down.

The best current explanation of why the universe is accelerating is that there is some energy tied to empty space which pushes matter apart. This ‘Dark Energy’ makes up 73% of the universe but is very difficult to detect. Hopefully a better understanding of it will lead to a unification of our theories of gravitation and quantum mechanics.

These amazing discoveries led to research on dark energy, a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe.

It is difficult to image there will be no stars, no planets or galaxies in the future.

We know that Andromeda known also as M31 is now 2.5 million light-years away, but it’s is approaching us very fast. It’s inevitably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that surrounds them both. A while ago, astronomers established the collision course between the two galaxies. Unfortunately, there is more to this story and it gets even worse.

“Our Milky Way will still be here and merge with some nearby galaxies,” Professor Schmidt said. “But other things we see today will not be able to reach us in the future. Every galaxy beyond the Milky Way will disappear. At that time, astronomers will all be unemployed because there will be nothing to work at.”

All galaxies will eventually vanish and the Universe will disappear. So maybe, we should find those extraterrestrial civilizations soon, because if Professor Schmidt is right, there will be no-one to search for in 100 billion years. Is this how it will all end one day? Source: Message To Eagle
