NASA Reveals That Our Universe is Going Through Unexpected Changes

Anybody who’s at least a bit interested in astronomy knows very well that the Universe is constantly expanding. It has been expanding since the Big Bang, which is thought to be the very moment when our Universe was born. 

Astronomers were stunned back in the 1920s when the observations of the American astronomer Edwin Hubble revealed that the Universe was expanding. Until that moment, the generally accepted idea for astronomers was that of a static model of the Universe. 

But astronomers kept discovering new things about the expansion itself. For instance, they were also surprised to find out that there’s a driving force behind the expansion itself that makes it accelerate. Without it, the Universe should stop expanding at some point and collapse back towards the singularity from where it came from roughly 13.7 billion years ago. That driving force is known as dark energy, and scientists know pretty much nothing else about it.

The Universe now expands much faster than expected

According to abc13.com, NASA revealed that the Universe is now expanding at a faster rhythm than expected after they’ve studied new data provided by the Hubble Space Telescope.

Scientists have also observed that other galaxies are moving away from our Milky Way faster than expected.

Here’s an important statement made in a news release, as the same publication mentioned above quotes:

The cause of this discrepancy remains a mystery. But Hubble data, encompassing a variety of cosmic objects that serve as distance markers, support the idea that something weird is going on, possibly involving brand new physics.

There are billions of galaxies out there in the observable Universe, so we shouldn’t think even for a second that scientists will ever run out of homework.

As you’ve probably already guessed, the Hubble Space Telescope that’s operated by NASA and the European Space Agency (ESA) and that gathered information about the Universe since 1990, was named after the great astronomer Edwin Hubble.

Today he's seeing his dream come true by writing about the latest news in astronomy. Cristian is also glad to be covering health and other science topics, having significant experience in writing about such fields.
