Un hyper trou noir a peut-être donné naissance à notre Univers

Un hyper trou noir a peut-être donné naissance à notre Univers | Beyond the cave wall | Scoop.it

Il est peut-être temps de dire au revoir au Big Bang. Des cosmologistes pensent que l’Univers s’est formé à partir de débris éjectés lorsqu’une étoile à 4 dimensions s’est effondrée en trou noir, un scénario qui expliquerait pourquoi le cosmos semble être uniforme dans toutes les directions.

First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories

First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories | Beyond the cave wall | Scoop.it
The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed by observations with both the W. M. Keck Observatory and the Gemini Observatory. The initial discovery, made by NASA's Kepler Space Telescope, is one of a handful of smaller planets found by Kepler and verified using large ground-based telescopes. It also confirms that Earth-sized planets do exist in the habitable zone of other stars.

Creationists demand equal airtime on Neil deGrasse Tyson’s ‘Cosmos’ to provide ‘balance’ | The Raw Story

Creationists demand equal airtime on Neil deGrasse Tyson’s ‘Cosmos’ to provide ‘balance’ | The Raw Story | Beyond the cave wall | Scoop.it

Creationists held a pity party for themselves Thursday because “Cosmos” isn’t being fair and balanced to their beliefs.

“Creationists aren’t even on the radar screen for them, they wouldn’t even consider us plausible at all,” said Danny Falkner, of Answers In Genesis, which has previously complained about the show.

On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly explain the results, in this improvised talk illustrated by Randall Munroe of xkcd.

Mlik Sahib's curator insight, April 1, 4:15 PM

“We live in this part of the universe because we can live there, not "because the whole universe is built for our benefit,” says Stanford University physicist Andrei Linde, one of the main authors of inflation theory and the multiverse hypothesis. This idea, called the anthropic principle, is satisfying to some, and maddening to others."

How Large is the Universe? - ScienceGymnasium | Beyond the cave wall | Scoop.it
The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end, and what lies beyond its star fields and streams of galaxies extending as far as telescopes can see? These questions are beginning to yield to a series of extraordinary new lines of investigation and technologies that are letting us to peer into the most distant realms of the cosmos. But also at the behavior of matter and energy on the smallest of scales. Remarkably, our growing understanding of this kingdom of the ultra-tiny, inside the nuclei of atoms, permits us to glimpse the largest vistas of space and time. - See more at: http://www.sciencegymnasium.com/2013/07/how-large-is-universe.html#sthash.13Mzn8gk.dpuf
