This week, unexpected new results from NASA’s Hubble Space Telescope shows that the galaxies are accelerating 9% faster away from each other than previously anticipated, astronomers are not quite sure why!
Matter as we know it, all the planets, stars, galaxies, cluster of galaxies that can be seen make up just 5 percent of the cosmos. Approximately 2% of this percentage is made of stuff astronomers can’t see but still eluded detection.
Our universe have some peculiar properties, properties that couldn’t be explained by conventional Big Bang theory. For example, it’s flat, meaning it’s at just the right mass density that it will neither expand forever nor collapse back on itself. Why should it be flat?
In 2004, researchers were combing through the data from a satellite called WMAP when they noticed something unusual. Part of the universe looked a lot colder than the rest. They called it, appropriately, the Cold Spot and scientists still aren’t really sure why it’s there.
On October 7th 2015 thousands of people reportedly witnessed a cloud of towering skyscrapers drifting above the city of Foshan, in the Guangdong province of China. These mystical skyscrapers appeared for only a few minutes before disappearing.
Here on Earth, radio waves help us communicate with one another. But in deep space, they might be able to help us find the Universe’s missing matter.
I’m sure you have found yourself looking up at the night sky and wondering just how big the universe is. How could you not?! It’s just so vast, and we are just so tiny! It’s almost impossible not to ponder just how vast it really is, how far it reaches.
We have a pretty good idea of how and when the universe began as for how it’s going to end, hmm?
Recently, I came across some really cool facts about the universe so I decided to gather up the most interesting ones to share with you guys, hope you enjoy them.
How fast the universe has been expanding since the Big Bang is something of a puzzling question. It wasn’t that long enough that we didn’t know it was accelerating at all, and a new study finds the acceleration of the expansion of the universe might not be as fast as thought.
Our universe has been in existence for nearly 14 billion years and science has led us to believe it will keep existing for many billions more. So, will the universe expand forever, or will it one day collapse under the influence of its own gravity?
