(University of York) New research by scientists at the University of York gives a fresh perspective on the physics of black holes. Conventional thinking asserts that black holes swallow everything that gets too close and that nothing can escape, but the study by professor Samuel Braunstein and Dr. Manas Patra suggests that information could escape from black holes after all.

(ESO) A team of European astronomers has used ESO’s Very Large Telescope and a host of other telescopes to discover and study the most distant quasar found to date. This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early Universe. The results will appear in the June 30, 2011, issue of the journal Nature.

(NASA/Goddard Space Flight Center) A study using NASA’s Swift satellite and the Chandra X-Ray Observatory has found a second supersized black hole at the heart of an unusual nearby galaxy already known to be sporting one.

Actuators respond to changes in conditions withina tunnel – either automatically or manually. Forexample, lighting plays an important role in theflow of traffic (and thereby in the safety of motorists, passengers, and freight). Siemens offers intelligentlighting, along with a wide range of actuators formany applications:

• Lighting
  The level of lighting must adapt to the changing ambient light at the tunnel entrance, and should neither dazzle drivers inside the tunnel nor allow the entrance to appear as a black hole.
• Ventilation
  The ventilation system provides fresh air in the tunnel and compensates for exhaust gases. The capacity of the ventilation system must be sufficient to supply enough air when the vehicles in the tunnel are stationary. In the event of a fire, the ventilation system removes smoke and poisonous views.
• Variable Message Signs, Speed Limit Signs
  Variable message and speed limit signs (VMS and SLS) use LEDs to display text information or traffic symbols. The LED elements are monitored by their control unit to prevent disrupted, illegible, or contradictory displays. An optional hardware lockout can also be installed.
• Lane Control Signs (LCS)
  Lane Control Signs use LEDs to display lane signals with arrows. The signals are monitored to prevent unsafe signaling states. An optional hardware lockout can also be installed.
• Traffic Lights
  LED traffic lights are located at each tunnel entrance. They are activated automatically if an overheight vehicle triggers the detector or if another type of incident requires a response. The traffic lights can be operated manually in addition to automatic activation.
• Barriers
  Barriers are optional additions to ensure that no more vehicles can enter the tunnel. Barriers can be either hydraulically or electrically driven.
• Lane Lights
  LED lane lights are set into the roadway surface, and can be used either for dynamic lane assignment or static shoulder marking.

White holes are objects that only show up in physical theories – none have yet been observed. When a black hole is formed, all the matter and energy that falls into it should go somewhere. The idea is that somewhere else, either in our own universe or another one, another “hole” is created, the opposite of a black hole. This is why it’s called a white hole. It’s theorized that matter and energy that falls into a black hole comes out of a white hole somewhere else.

This is only science fiction at this point, and it may not be correct at all. Steven Hawking discovered something called Hawking Radiation where, in addition to matter falling into black holes, energy is also emitting as the black hole “dies”. This may account for all of the “lost” energy.
