How to test if we're living in a computer simulation

There is some evidence suggesting that our physical reality could be a simulated virtual reality rather than an objective world that exists independently of the observer.

The Universe may not look the same in all directions

One of the core assumptions of astronomy is that the universe appears the same in all directions, or it is isotropic. However, a recent study suggests that may not be the case. 

How Possible Life Is In The Universe

It's calculated that, thanks to rapid inflation, the universe may contain more than 1 googol (10^100) stars, and if this is the case then more complex, life-sustaining RNA structures are more than just probable, they're practically inevitable.

Our universe: An expanding bubble in an extra dimension

Swedish researchers have devised a new model for the Universe, that may solve the enigma of dark energy. They proposes a new structural concept of a universe that rides on an expanding bubble in an additional dimension.

NASA's Technosignatures Report is Out

Technosignatures are what we humans would recognize as signs of technologically-advanced activity of an extraterrestrial intelligence.

Astonishing New Theory Could Explain Universe’s Missing 95%

UK researcher, Jamie Farnes, suggests both dark energy and matter can be unified into a single substance — a negative-mass ‘dark fluid.’ The theory may also prove right a prediction that Albert Einstein made 100 years ago.

New Mysterious Space Object Nicknamed "The Cow"

A mysterious cataclysm in a neighboring galaxy was spotted in the sky above Hawaii last week, sending astronomers around the world scrambling to understand the source of the staggeringly brilliant flash.

Life May Be Billions of Times More Common in the Multiverse

While there is no physical evidence that parallel universes exist, the theories that explain how our universe came to be seem to suggest that they are inevitable.

Could dark matter atoms explain a recent observation?

A tiny fraction of dark matter could have a charge, allowing it to interact with regular matter during the time between the Big Bang and formation of the Cosmic Microwave Background, some physicists say.

Stephen Hawking's final theory about the big bang

The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say.

Researchers Just Scanned 14 Worlds for evidence of Advanced Civilizations

In the Search for Extra-Terrestrial Intelligence (SETI), a team of astronomers recently searched through the Kepler field to look for signatures of technologically-advanced civilizations.

Mysterious Filament near Milky Way's Supermassive Black Hole

Looking to the center of our galaxy, astronomers noted the presence of a mysterious filament extending from the supermassive black hole located there.

The Multiverse?

Merging Neutron Stars Challenge Existing Theories of Gravity and Dark Energy.

Twinkle in a forming star suggests existence of a very young planet

An international team of researchers have found an infrequent variation in the brightness of a forming star. Its repeated behavior suggests the presence of a hidden planet.
