Einstein is always right.

Hi there cosmic entities!

Ian here for DNews…. and prepare to have your mind BLOWN.

Researchers have created an incredible 3-dimensional map of a region of the universe.

As part of the Baryon Oscillation Spectroscopic Survey, or BOSS,

they pinpointed a whopping 1.2 million galaxies covering a quarter of

the visible sky!

It's a volume that is about 650 cubic billion light years big.

Within that huge expanse, astronomers start to see the large-scale structure of the cosmos

between two to seven billion light-years away.

In other words, they're spying on the universe as it was two to seven billion years AGO.

And it just so happens that this is an important era to study if we are to understand the strange

effects of dark energy.

Now, dark energy makes up for 70% of ALL the energy in the universe and has a bizarre anti-gravity

effect on space-time, causing it to expand.

And the expansion is accelerating.

So cosmologists REALLY want to know what dark energy IS and how it's going to shape the

evolution of the universe.

In an effort to get to grips with this mysterious energy, astronomers need to think really big,

capturing the motion of a HUGE number of galaxies.

This is where BOSS comes in.

Now...things get a little more complicated.

So bear with me.

At the moment of the Big Bang, 13.82 billion years ago, there was just energy.

As time went on, the universe expanded and cooled and matter started to condense to form

the quarks, atoms, electrons and all that other good stuff our universe contains.

During this early time, baryon acoustic oscillations, or BAOs, rippled through the early universe.

You can imagine these BAOs as a bit like sound waves traveling through a gas.

They created regions of dense matter and regions empty of matter.

The BAOs started out small, but as the universe expanded, they expanded with it and became

larger, leaving their fingerprint in the structure of the universe.

As this happened, clusters of galaxies formed inside the high density regions caused by

the BAOs.

The most incredible thing is that BOSS can SEE the BAOs in the galaxies recorded in this

massive 3D map.

But what does this mean?

Well, in this new research published in the Monthly Notices of the Royal Astronomical

Society, astronomers have specifically looked back into the time when it is theorized that

dark energy really took hold of universal expansion, causing vast galactic clusters

to fly away from one another.

By studying those 1.2 million galaxies that existed between 2 to 7 billion years ago,

and recording the distance between the dense clusters, we can see how fast the universe

expanded under the force of dark energy.

And it appears the universe is expanding in PRECISELY the way we THEORIZED, with dark

energy continually stretching spacetime while the gravity of dark matter is trying to pull

it all back in again.

This gives us further evidence for the existence of dark matter AND dark energy.

But do you want to know the best thing?

By studying the motions of so many galaxies over such a huge volume, this research has

shown that general relativity holds true over cosmological scales.

Yes, Einstein's theory has been proven correct again.

Shocker.
