Earth is far from the center of the universe

There is no denying we humans are obsessed with real estate. We always like to think we've landed ourselves a prime piece of land to settle on, and that outlook extends past your home, vacation home, and country and all the way out to the Earth itself.

Fortunately, a brilliant Polish astronomer named Nicolaus Copernicus wrote a little book in 1543 called On the Revolutions of the Heavenly Spheres, which officially struck down the idea that the Earth was the center of the universe. He even got a scientific law named after him, the Copernican Principle, which states that our galactic position is nothing but ordinary. Despite the fact that this principle is one of the building blocks of modern cosmology, people still want to prove we've gotten an extraordinary deal with our planet's location. And, unfortunately for most cosmologists, while it's easy to show all the ways in which our neighborhood is not special, it's very difficult to prove conclusively that it isn't.

In the late 90s, some studies suggested that Earth had a notable place on the cosmic block by placing the Earth near the center of a "bubble" that was mostly empty of matter. The universe was not really expanding at an accelerating rate due to dark matter, but rather, gravity was creating an illusion of acceleration of supernova observations.

Today, a team of astronomists are essentially calling the so-called "void theory" a bunch of cosmic bologna. The team members tested void models against the most recent data (cosmic microwave background radiation, ripples in the large-scaled distribution of matter, etc.) and the models failed to explain the current state of the universe. Dark energy models, on the other hand, do a far better job, even though dark energy remains an enigma. The conclusion of the report solidified the widely-held opinion that dark energy is responsible for the acceleration of our expanding Universe.

The fraud: Void Theory.

The winner: Dark Energy.

It's all about your point of view, of course. From where we stand, we are the center and everything radiates out from around us. Martians might be staring straight at us and thinking the same thing about themselves. If we remain insistent that we have the best lot in the development though, we at least have to come to terms with the fact that we are far more ordinary than the mysterious dark matter that fills the universe. Not even The Donald can Trump that.

I think they might be jumping the gun on this story it's one small group of astronomers in Canada who claim to have debunked the void theory.
The CBC is uneven so matter concentrations also should be uneven thus making voids a likely possibility.
Other issues it's been recently found that not all Type 1a super nova are the same brightness.
A theory cannot be considered dead or a fraud unless more then one party finds evidence pointing to the theory being wrong this is how science works.

More than that, the answer goes back to whether in a rigorously "scientific" sense we can really ever believe in anything that we are not directly observing or can not see. Quantum physics suggests that we can't, but if that restriction holds on the macro scale, then the Earth is at the center of the universe, because in whichever direction we gaze we can see only about 13.7 billion light years and no further!

You can argue until the cows come home about how the universe goes on much beyond that, is infinite, has other dimensions with infinite parallel universes spinning off it, etc. but the cold hard fact at the end of the day is that from what we can see we are smack dab in the center of this universe.

Hey it's all relative, in an Einsteinian sort of way. After all isn't time just an illusion created by the manufacturer of space?

Are you sure Void Theory is really dead?

According to [scientists], [christian beliefs], in the beginning was the void. The universe, according to current theory, somehow exploded into this void.

If we assume that a void is like a vacuum, then perhaps the expansion of our universe at an ever increasing rate, is the result of this universe being surrounded on all sides by a void/vacuum that our universe is rushing to fill. That is, that it is being sucked into the vacuum on all sides, which would cause it to stretch a lot near the edges, and not so much near the center. Might we perceive this stretching as increased velocity (as bodies would traverse the same distance, but that distance would be stretched).

Noone ever postulated that the exploding universe ever replaced the void into which it exploded - hence, the void is probably still there!
