Astronomers Discover The Earliest Echoes Of The Big Bang
2014-03-17 13:23:58

Astronomers publishing a paper in the journal Nature say they have found the first direct evidence that gravitational waves rippled through the early Universe during the inflation period.

Massive Neutrinos Help Solve A Cosmological Conundrum
2014-02-10 09:36:04

Scientists have solved a major problem with the current standard model of cosmology identified by combining results from the Planck spacecraft and measurements of gravitational lensing in order to deduce the mass of ghostly sub-atomic particles called neutrinos.

If most physicists claimed that the popular notion of black holes as event horizons from which light cannot escape is wrong, they would be almost immediately dismissed (and possibly even scoffed at). However, when Stephen Hawking makes such an assertion, the scientific community stands up and takes notice.

Gravity Clues From Stellar Triple System
2014-01-06 03:39:45

The discovery of a superdense neutron star in a stellar triple system has made it possible for researchers to collect the best measurements to date of the complex gravitational interactions present in these types of systems, according to a new Nature study.

Wormholes Driving Quantum Entanglement
2013-12-04 15:25:47

Two physicists have theorized that wormholes could be the cause behind the bizarre phenomenon known as quantum entanglement.

ESA Missions Will Seek To Understand The Evolution Of The Universe
2013-11-29 07:25:17

The European Space Agency (ESA) announced today that the hot and energetic Universe and the search for elusive gravitational waves will be the focus of their next two large science missions.

Revealing New Information On Strength Of Black Hole Mergers
2013-11-08 07:13:10

Giant black holes throughout the universe sometimes pair up and merge, sending out gravitational waves that ripple across space and time. Albert Einstein predicted that these waves exist, but scientists have yet to directly detect one.

Two Black Holes Form, Fuse Together After Star Collapses
2013-11-07 07:17:18

Black holes are massive objects in space that have gravitational forces so strong that not even light can escape them. These objects, swirling at the centers of galaxies, also come in a variety of sizes.

Colliding Galaxies Create Supermassive Black Holes
2013-10-23 16:17:25

At the center of almost every galaxy we have studied is a black hole of such magnitude that the traditional black hole progenitor does not seem likely. These aptly named supermassive black holes can reach millions or billions of times the mass of our Sun.

Modified Gravity Theory Predicts Galaxy Dynamics
2013-08-29 10:22:45

Observational of distant galaxies suggests one of two possibilities: either these galaxies contain significantly more mass than what is seen, or our physical understanding of gravity is flawed.

String Theory -- A string theory is a physical model whose fundamental building blocks are extended objects (strings, membranes and higher-dimensional objects) rather than points. String theories are able to avoid problems, such as infinite energy density, associated with the presence of mathematical points in a physical theory. The term 'string theory' properly refers to both the 26 dimensional bosonic string theories and to the 10 dimensional superstring theories discovered by...

Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...
