    Did a hyper-black hole spawn the Universe?

    Big Bang was mirage from collapsing higher-dimensional star, theorists propose.



    It could be time to bid the Big Bang bye-bye. Cosmologists have speculated that the Universe formed from the debris ejected when a four-dimensional star collapsed into a black hole — a scenario that would help to explain why the cosmos seems to be so uniform in all directions.


    The standard Big Bang model tells us that the Universe exploded out of an infinitely dense point, or singularity. But nobody knows what would have triggered this outburst: the known laws of physics cannot tell us what happened at that moment.


    “For all physicists know, dragons could have come flying out of the singularity,” says Niayesh Afshordi, an astrophysicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada.


    It is also difficult to explain how a violent Big Bang would have left behind a Universe that has an almost completely uniform temperature, because there does not seem to have been enough time since the birth of the cosmos for it to have reached temperature equilibrium.


    To most cosmologists, the most plausible explanation for that uniformity is that, soon after the beginning of time, some unknown form of energy made the young Universe inflate at a rate that was faster than the speed of light. That way, a small patch with roughly uniform temperature would have stretched into the vast cosmos we see today. But Afshordi notes that “the Big Bang was so chaotic, it’s not clear there would have been even a small homogenous patch for inflation to start working on”.
    I have no agenda here (just to calm down SU). Just posting interesting stuff, no matter which theory is supported or questioned.

    Well, because he thought it was good sport. Because some men aren't looking for anything logical, like money. They can't be bought, bullied, reasoned, or negotiated with. Some men just want to watch the world burn.

    Water on Earth and the solar system is older than our sun

    Much of the life processes on Earth depend on the sun, so it comes as a surprise to many when new research findings suggest that some of the water in the Earth's oceans is actually older than the solar system's sun. The discovery could have implications on understanding how planetary systems form....

    Look, stop mocking me. It's been revealed to me that Adam and Eve came here in a space ship. You could know this too if you'd just be more humble.

    Andromeda is the nearest spiral galaxy to the Milky Way. To put things in perspective, if the orbit of Neptune were the size of a $0.25 cent quarter, the nearest star (Proxima Centauri) would be 371.6 feet away, the nearest Black Hole (V4641 Sgr) would be 26.5 miles away, the Milky Way would be 1,200 miles across, and the nearest point of Andromeda would be 41,340 miles away.

    The Paradoxes That Threaten To Tear Modern Cosmology Apart

    Some simple observations about the universe seem to contradict basic physics. Solving these paradoxes could change the way we think about the cosmos

    The Thread about the Universe, Astronomy, and Similar Cool Stuff

    A few weeks ago while down in St George I took my kids out into the desert away from any city lights to look at the stars. I had downloaded the Sky Guide app which lets you point your phone at something and figure out what it is. One of the highlights was seeing the ISS pass from horizon to horizon.

    If you are a person like me who knows little about the constellations or what not that app is fantastic. You point it to where you are looking, click on what you are interested in and it gives you all the facts, or in the case of constellations the mythology behind them. Really amazing.

    How to View Five Planets Aligning in a Celestial Spectacle

    19PLANET-superJumbo-v2.jpg

    Five planets paraded across the dawn sky early Wednesday in a rare celestial spectacle set to repeat every morning until late next month.

    Headlining the planetary performance are Mercury, Venus, Mars, Saturn and Jupiter. It is the first time in more than a decade that the fab five are simultaneously visible to the naked eye, according to Jason Kendall, who is on the board of the Amateur Astronomers Association of New York.

    That new planet is enormous. But isn't it extremely far away? As I recall it's solar year is around 15,000 earth years. (For reference, Neptune's year is ~165 earth years)

    And Pluto had it's chance. There are a number of objects larger than Pluto that also orbit the sun, but are not considered planets.
