The Big Bang theory is the prevailing cosmological model that describes the early development, but not the origin, of the Universe.[1]
Renowned physicist, famous for his study of black holes, galaxies and for authoring a popular book on the origin of the universe, “A Brief History of Time”, recently arrived at Caltech, like every year, where he held a talk in front of 1,000 people who had waited in line for 12 hours to hear him speak. [...]
A decade ago, American physics professor John Cramer released an audio file which made history: the sound of the theorized Big Bang that formed the universe. Now, armed with new data and more observations, Cramer has released a remix – an improved version of the universe’s first one hit wonder. “In general, there are no sounds [...]
Using the incredible Planck cosmology probe astronomers at the European Space Agency have assembled a map of the “oldest light” in the sky – the cosmic microwave background (CMB) that was thrown into space in all directions just a few hundred thousand years after the Big Bang and which is still picked up here on Earth today. [...]
NASA scientists have announced they have discovered the farthest object discovered so far in the Universe, a 13.3 billion old galaxy or a mere 420 million years after the Big Bang. That’s not to say that its 13.3 billion light years away from Earth, since the Universe has expanded greatly since then and the actual [...]
The first galaxies formed very fast after the Big Bang – in cosmic time, that is. It’s estimated that the earliest ones appeared some 500 million years after the Big Bang, a period about which researchers know very little. How they observed it Even though they are typically very bright, such galaxies are quite hard [...]
First discovered in 2005, and then studied in more depth since 2007, NASA scientists have finally isolated the ethereal glow thought to originate from the very first objects in the Universe with the highest precision yet. As seen in the image above, depicted in orange and red, the ‘lumpy’ infrared glow was observed using the [...]
Backed by an international consortium, ten years from now the world’s largest and most sensitive radio telescope in the world will be built – the Square Kilometer Array (SKA). The project will consist in thousands of antennas displaced across thousands of miles, with a collecting area equivalent to one square kilometer (hence the name), that [...]
One of the fundamental backbones of the Big Bang theory states that after the rapid expansion of the Universe only the lightest elements were formed. A group of scientists stumbled across an amazing discovery recently when they found a gas cloud dating from the time of the early Universe exclusively made out of hydrogen and helium, proving [...]
Astronomers have discovered the largest body of water so far known, a reservoir of water floating in space around a ancient distant quasar, holding 140 trillion times the mass of water in the Earth’s oceans. Remarkably enough, the find was dated as being 12 billion light years away, only 1.6 billion light years farther from [...]
The Large Hadron Collider (LHC) continues on its quest to find out exactly what happened in the first seconds after the Big Bang, unveiling what is the densest material known so far to man. Exotic densest substance Known as the quark-gluon plasma, this amazing exotic substance can exist only at incredibly high temperatures or pressures, [...]
An intriguing hypothesis was brought up by Professor Bernard Carr from Queen Mary University in London and Professor Alan Coley from Canada’s Dalhousie University, who claims that some of the black holes we see today may actually be remnants of a past universe that collapsed into itself after a Big Crunch. I don’t know about [...]
Yes, you’ve read that right. There are over 50 billion planets in our galaxy alone, according to the Kepler telescope, scientists now estimate that not only there are over 500 bilion planets in the galaxy, but that there are over 500 million life-cable planets out there as well. These numbers obviously come from Nasa’s own [...]
When early galaxies formed, there was a surprisingly high rate of new stars being formed, which was explained by major galactic collisions; however, recent evidence suggests that in fact the answer is much simpler, and not nearly as violent. Astronomers using the European Southern Observatory’s Very Large Telescope in Chile have observed three ancient galaxies [...]
The researchers and engineers operating the Large Hadron Collider have smashed together for the first time protons, in what is considered a huge step forward by pretty much everybody working at the huge physics experiment. The particles were accelerated on Monday, through the LHC’s 27 km and then ‘drove’ into each other, in an attempt [...]
