    How to estimate/calculate stellar wind from a star?

    Stellar Flux and solar wind would become less concentrated as it 'expands' out, so a star several light years away would have very little of its solar wind hitting earth. A magnetic field from a planet there could pick up some of that material and fling it another direction, (this is also a...

    What is Stellar Flux and How Does it Affect Solar Wind?

    I have a little problem about Stellar Flux. I've searched google and bing for info but to no avail. Please help me understand Stellar Flux. Thanks, Epicall Rounder

    Why does surface area of an Event Horizon increase?

    It increases due to the black hole pulling more material into itself, therefore trapping it in the event horizon, enlarging it. The material would get trapped into an 'orbit' around the black hole. Never able to escape, neither get pulled into the black hole.

    Sagittarius A* and its event horizon

    Well, all that is known at the moment is that we have more knowledge of Sgr A* having a event horizon, but not certain. X-Ray and Infrared images have proven that it has a certain "strange pulsing light" after putting a few thousand images into a slideshow. Scientists have also became nearly...

    Why aren't there any space tugs in use?

    The Ion Thruster is still a very low-thrust engine which would need many of them to be used as a tug. The Thrust-to-Weight ratio of an ion engine is too low to be used in LEO effectively, so it would be too power consuming to power the Ion Thruster. Even if a particular spacecraft had the...

    Energy cannot be created. Then where did it all come from?

    You are completely correct. As you said, this is entirely speculative and I have no real proof of this theory, but it is something interesting to think about. Then again, with the amount of space the universe, and how it's enlarging, with the universe at googolplex metres across would make even...

    Energy cannot be created. Then where did it all come from?

    This is a theory, not necessarily fact. Energy cannot be created in this universe, but the laws of physics may not be relevant to another "universe" or "dimension" for example, one universe creates energy and it could be "teleported" through the universes and dimensions to our universe using the...
