Black Holes


NASA is on a ROLL!

Physics is having a break down,  the understanding of matter which exist in a Black Hole.  NASA is working on this with the new X-Ray Telescope called NuSTAR on a Pegasus’ rocket.

From NASA:

The Nuclear Spectroscopic Telescope Array is an Explorer mission that will allow astronomers to study the universe in high energy X-rays.  Launching in 2012, NuSTAR will be the first focusing hard X-ray telescope to orbit Earth and is expected to greatly exceed the performance of the largest ground-based observatories that have observed this region of the electromagnetic spectrum.  NuSTAR will also complement astrophysics missions that explore the cosmos in other regions of the spectrum.

X-ray telescopes such as Chandra and XMM-Newton have observed the X-ray universe at low X-ray energy levels. By focusing higher energy X-rays, NuSTAR will start to answer several fundamental questions about the Universe including:

  • How are black holes distributed through the cosmos?
  • How were heavy elements forged in the explosions of massive stars?
  • What powers the most extreme active galaxies?

NuSTAR’s primary science objectives include:

  • Conducting a census for black holes on all scales using wide-field surveys of extragalactic fields and the Galactic center.
  • Mapping radioactive material in young supernova remnants; Studying the birth of the elements and to understand how stars explode.
  • Observing relativistic jets found in the most extreme active galaxies and to understand what powers giant cosmic accelerators.

NuSTAR will also study the origin of cosmic rays and the extreme physics around collapsed stars while responding to targets of opportunity including supernovae and gamma-ray bursts.  NuSTAR will perform follow-up observations to discoveries made by Chandra and Spitzer, and will team with Fermi, making simultaneous observations which will greatly enhancing Fermi’s science return.

NuSTAR  Arrives

On June 7th at around 01:40 UTC NuSTAR safely inside the Pegasus rocket mounted under the L-1011 aircraft touched down at Bucholz Army Airfield on Kwajalein Island ahead of launch.

NuSTAR Launch

NASA’s X-Ray Telescope called NuSTAR successfully dropped from a L-1011 aircraft today at 16:00 UTC. 5 seconds later the Pegasus’ first stage ignited, 14 minutes later after three burns the NuSTAR Spacecraft was separated from the rocket after reaching the correct orbit.

Black Hole Horizon

This will be the Holy Grail of science, understanding all matter of nature.

From Wikipedia:

black hole is a region of spacetime where gravity prevents anything, including light, from escaping.  The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole.  Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return.  It is called “black” because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics.   Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature.  This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed it can continue to grow by absorbing mass from its surroundings.  By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may form.  There is general consensus that supermassive black holes exist in the centers of most galaxies.

Thanks Wikipedia,  it’s hard explaining theory that physics is having a problem with.  The consensus on Black Holes is their mass is the heaviest of all matter.  With NuStar,  new information for physics is coming soon with new theories.  Astronomers are closing in on proof that a supermassive black hole is the source of mysterious radio waves at the center of our galaxy,  the Milky Way.

Wow now think about that,  would make sense since Black Holes have the heaviest mass along with gravitational pull.   Like pulling the drain stop on the tube when you were a kid,  Donald Duck along with your boat would be pulled to the drain horizon and spin in the vortex.

Science has calculated that our universe is 13.5 billion years old.  Calculating that time with expansion there are Physical Review Letters that puts a lower limit on the size of the universe at no smaller than 46.5 billion light years in radius.  If the universe is geometrically flat, that is.   Geometrically flat,  sounds like the times that people saw the world as flat.

Just might be one Mother of a Hole out there pulling all matter towards it!   It’s expanding alright,  but where to?  A Horizon?
