A journey to the beginning of the universe lurched forward Monday with a trek over just a few hundred feet.

Long before we had the atomic theory of matter, scientists knew the air was real, even though it was invisible.

The scientists behind the BICEP2 (Background Imaging of Cosmic Extragalactic Polarization) telescope, last year made an extraordinary claim that they had detected gravitational waves, which are ripples in space-time.

Neutron stars are arguably the most exotic objects in the universe.

Is it possible that we are overlooking extraterrestrial signals in our search of the skies for intelligent alien life? If alien life does exist in our galaxy and beyond, is it possible that its signals could be similar to what we detect and label as pulsars? We see pulsars as a natural phenomenon, but what if that’s not the case?

Did dark matter kill the dinosaurs? Recent work by Harvard physicists may have us reevaluating the mysterious substance of dark matter, and how the dinosaurs became extinct.

Some of the world’s most brilliant scientists have investigated whether time travel could one day be made a reality and references to time travel are ubiquitous in ancient lore.

Dr. Edward Dowdye Jr. challenges Albert Einstein’s fundamental theories as they are widely taught in schools today.“I believe if Einstein were alive today ... he would wind up disproving his own theory.”

The recent BICEP2 observations – of swirls in the polarisation of the cosmic microwave background – have been proclaimed as many things, from evidence of the Big Bang and gravitational waves to something strange called the multiverse.

If the Big Bang theory is just a “theory,” are there other hypothetical explanations for the origin of the known universe?

Could aliens be shrouded by dark matter and the event horizon of black holes? Astronomers understand particularly little of what goes on in these mysterious regions of the universe.

Mysterious radio bursts from billions of light years away—one of many reasons to listen to the skies.

It’s a beautiful universe ... take the tour.

The European Organization for Nuclear Research (CERN) has shown a particle with a mass which matches that of the hypothesized Higgs boson or so-called god particle.

“The universe consists only of atoms and the void; all else is opinion and illusion.”
