The Universe is full of mysteries and unexplained phenomenons. Its sheer size alone is a mystery in it of itself and lets not even talk about whats contained within it (though we are going to talk about it in this post). After all, what is the universe? According to Wikipedia, it is all of time and space and its contents. It includes planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy. A pretty standard answer and probably a disappointing one to many. If you search a little deeper, however, you will find that science has some mind-blowing answers to this seemingly simple mysteries.
Consider for a moment some of the theories out there: Science claims among other things that the universe could be a an illusion, a computer program, or even a bubble. Of course, the questions that derive from such claims are as many as the stars (if we knew how many start existed): Where did I come from? Where do I go? How much time do I have left? What’s the purpose of being here? All these questions may sound like queries for a philosopher to unravel, but if you are seeking a more scientific response, you might be end up with a huge question mark. These are 25 Most Puzzling Mysteries of The Universe.
How old is the universe?
At the dawn of the twenty-first century and despite all our technological and scientific progress, the universe’s age remains far from certain. Current estimates place the age of the universe at 13.799±0.021 billion years.
How did galaxies form?
There’s a lot of debate as to how galaxies formed but at the end of the day, no one knows for sure. After the Big Bang, scientists are not sure if small particles slowly teamed up and gradually formed stars, star clusters and eventually galaxies or if the Universe first organize as clumps of matter that later subdivided into galaxies.
What are the Fermi bubbles?
In 2010, a team of scientists working at the Harvard–Smithsonian Center for Astrophysics discovered a pair of “Fermi bubbles” extending tens of thousands of light-years above and below the Milky Way’s disk. These structures are enormous balloons of energetic gamma rays emanating from the center of our galaxy, but there are still a lot of things we don’t know about them.
Have we really discovered a rectangular galaxy?
It’s being called the “emerald-cut galaxy,” and it was recently discovered by an international team of astronomers with the Swinburne University of Technology in Australia. The gem-cut galaxy was detected in a wide-field image taken with the Japanese Subaru Telescope by astrophysicist Dr. Lee Spitler. It’s believed that the unusual shape is the result of a collision between two galaxies.
The Universe before the big bang
What, if anything, existed before the big bang? We have been able to single out the genesis of our known existence to the Big Bang but beyond that we are still clueless.
