Physicists speculates our universe may be inside a black hole

Posted on Saturday, April 10 2010 @ 10:01:16 CEST by

Indiana University theoretical physicists Nikodem Poplawski has proposed a new theory to explain the origin of cosmic inflation:
In a paper written by an Indiana University theoretical physicist, Nikodem Poplawski, which appears in Physics Letters B, it is suggested that the universe was born from a wormhole that lies inside a larger universe.

Poplawski suggests that our universe could have been born inside a wormhole, or an Einstein-Rosen Bridge. This is a theorized phenomenon that provides solutions in general relativity when it combines models of black holes and white holes.

Someone Tell NASA: You Can't Fly Into A Black Hole

Someone Tell NASA: You Can't Fly Into A Black Hole

According to a paper just released at ScientfiicBlogging.com, despite all the theorizing by scientists and scenes in sci fi movies, it is impossible to fly into a black hole. So says research and development engineer Marshall Barnes who just happened to use NASA Hubble Space Telescope data to make his assertion. The funny thing is that last year, Shuttle astronaut Dave Wolf told a young British boy named Cameron that no one knew for sure. http://www.youtube.com/watch?v=1g_PjqpL9Z4&feature=player_embedded

The case that Marshall builds against the idea is as compelling as it gets. First using Hubble photos and analysis, he explains that tremendous X-ray radiation is emitted that travels far beyond the hole's accretion disc. This would kill you as, in some cases, it is a million times the level emitted by the sun. Then as your spacecraft gets closer, the heat from the clouds that surround the black would cook your space ship. These gaseous clouds, he reports, sometimes reach 50 million degrees. The Space Shuttle, Marshall points out, is rated to withstand a measly 2,600 degrees. Then, finally, before your incinerated space wreck can even reach the black hole, the tremendous gravity forces of the accretion disc, the massive swirling ring that surrounds the black hole, would grind the battered craft into gas which would leave nothing recognizable to "fly" into the black hole itself.

Marshall reports in his paper, titled, Predictable
Barriers Precluding Any Consideration of Transversable Black Holes Through Outer Space [http://www.scientificblogging.com/temporal_mechanic/blog/predictable_barriers_precluding_any_consideration_transversable_black_holes_through_outer_space_0] , that the whole idea of going into a black hole began when scientists were making calculations in the early 1900s for the physical properties of black holes, and calculating what would happen if someone were to fall into one was done strictly as an exercise in determining the effect of the gravitational tidal forces on a human body.Then it was discovered that theoretically there could be a way to navigate certain kinds of rotating black holes to reach parallel universes. The problem, as Marshall so astutely proves, was that no one was paying attention to the physical properties outside the black hole. To say that they are hostile is an understatement of the first order. The result is that over the decades, all the talk was centered around what could and what might happen if you flew into one while no one was paying any attention to the data describing the black hole's hostile neighborhood, which precludes, as the paper's title suggests, all consideration for transversable black holes.

Perhaps someone at NASA should give Marshall Barnes a call. It sounds like they need someone to bring their astronauts up to speed on a few things.
