In-depth studies of the Universe have revealed years ago that the overall rate of star formation peaked when the Cosmos was only a few billion years old. Since then, it has been in a steep decline, and a new study proposes that dark energy may somehow be responsible for this. When it comes to forming new stars &ndash... |

In a recent series of experiments, experts were able to demonstrate that the 20 amino-acids currently making up the basis of all lifeforms were not selected at random. Of the 100+ such molecules, this set proved to be the most efficient. This hints at the fact that life can arise on a whim on other worlds too.For yea... |

An international collaboration of researchers determined that the most ancient stars observable in the Milky Way were not in fact produced within our galaxy. These objects are what remains of old galaxies that once collided with our own, helping it grow to its current size. Though not particularly large, the Milky Wa... |

For several years, physicists have been trying to harness the power of quantum physics to produce a quantum computer. This device would far exceed the capabilities of normal computers, but building it is proven to be very hard. Researchers now propose using black holes as quantum computers.According to Seth Lloyd, wh... |

Physicists have recently taken an interest in testing to see whether the Multiverse hypothesis is correct or not. This idea holds that the entire Universe is contained within a bubble, which is itself just one of many such bubbles in the Multiverse. Though this idea has been proposed some time ago, experts are only n... |
