The Ultimate Paradox: Travelling Faster Than Light Without Travelling Faster Than Light
When Albert Einstein stipulated his theories on general and special relativity, he proved that travelling with the speed of light is the absolute limit any material object could achieve. Yet in 1994 a Mexican scientist said that it was possible to travel faster than light, while Einstein’s theories would still … READ MORE

How the Big Bang’s alternatives died (Synopsis)
“We were marching down the street, & we were at the head of the troops. We went on marching, & the troops went off to the left.” -Geoffrey Burbidge It’s such a part of our cosmic and scientific history, that it’s difficult to remember that it’s only been for the past 50 years that the…

The Impact of Dust...
Image Credit: ESA - Planck Collaboration(Inside Science) -- "Extraordinary claims require extraordinary evidence." This phrase, popularized by the late Carl Sagan, kept going through my head on March 17, the day that researchers involved with BICEP2, a telescope in Antarctica, made a big announcement at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. The researchers reported that BICEP2 detected gravitational waves from the first moments after the big bang, a feat, […]

Cosmic Inflation, BICEP2 and Planck
Cosmic inflation is the exponential expansion of space in the early universe. In other words, how did the universe go from being so small at the time of the big bang to the size it is today? But why do we even think this occurred? In the 1920's, astronomer Edwin Hubble noticed when looking at galaxies through a telescope, that the galaxies were actually moving away from one another. The further apart they were, the faster they moved. The only logical explanation for this was that the universe […]

Researchers have honed a way to probe the quark-gluon plasma, the kind of matter that dominated the universe immediately after the big bang.
By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, ‘perfect fluid’ that give clues to the state of the young universe just microseconds after the Big Bang. The multi-institutional team known as … Continue reading →

Un modello della gravità in uno spaziotempo a più dimensioni
Di recente, abbiamo pubblicato un articolo su un modello ‘alternativo’ che descrive l’origine dell’Universo da un buco nero multidimensionale (post). Al momento, nessuno sta abbandonando il modello del Big Bang dato che il lavoro proposto da tre teorici non è ancora stato soggetto a revisione e poi non presenta una vera e propria alternativa al modello […]

Throwback Thursday: How Big is Our Observable Universe? (Synopsis)
“The mind, once expanded to the dimensions of larger ideas, never returns to its original size.” -Oliver Wendell Holmes But it isn’t just your mind that expands as time goes on and you increase your knowledge, but the entire Universe as well. General Relativity, as it turns out, doesn’t leave us with much of a…

How It Works...
Source: The EconomistI have four previous posts about BICEP2 and how the initial roll out (i.e. announcement) was heady for some; aggrandizement for others.This next to the last paragraph at the bottom of The Economist sums it succinctly:Rowing back on a triumphant announcement about the first instants of creation may be a little embarrassing, but the saga is a useful reminder of how science works. There is no suggestion that anyone has behaved dishonourably. Admittedly, the BICEP team’s […]
