Universe

A step closer to explaining our existence

Publication: msnbc.com   Date: July 1, 2011   View Article

Why are we here? It remains one of the largest unexplained mysteries of the universe, but particle physicists are gaining more confidence in a result from an atom smashing experiment that could be a step toward providing an answer.

We exist because the universe is full of matter and not the opposite, so-called antimatter. When the Big Bang occurred, equal parts of both should have been created and immediately annihilated each other, leaving nothing leftover to build the stars, planets and us.

Thankfully, it didn’t happen that way.

Universe’s Existence May Be Explained by New Material

About 13.7 billion years ago, the big bang created a big mess of matter that eventually gave rise to life, the universe, and everything. Now a new material may help scientists understand why.

The material was designed to detect a theorized but unproven property of electrons, subatomic particles with a negative charge that orbit the centers of atoms.

If this “new” property of electrons exists, scientists say, it would help explain the current imbalance between matter and antimatter in the universe.

New Proof Unknown “Structure” Tug at Our Universe

“Dark flow” is no fluke, suggests a new study that strengthens the case for unknown, unseen “structures” lurking on the outskirts of creation.

In 2008 scientists reported the discovery of hundreds of galaxy clusters streaming in the same direction at more than 2.2 million miles (3.6 million kilometers) an hour.

This mysterious motion can’t be explained by current models for distribution of mass in the universe. So the researchers made the controversial suggestion that the clusters are being tugged on by the gravity of matter outside the known universe.

Check out ten images featured in “From Earth to the Universe,” one of several projects organized for the International Year of Astronomy. More than 40 countries have announced plans to participate. About 125 space images are available for display in airports, parks and other public places around the world. Some of the images here just might show up at an exhibit near you.

Unknown “Structures” Tugging at Universe, Study Says

Something may be out there. Way out there.

On the outskirts of creation, unknown, unseen “structures” are tugging on our universe like cosmic magnets, a controversial new study says.

Universe’s “Missing” Matter May Lurk in Dwarf Galaxies

Astronomers believe they may have found a significant portion of the universe’s “missing” matter.

The mysterious dark matter may be giving invisible heft to small galaxies formed during galactic collisions, a new study says.
