    Can Light Orbit a Black Hole Inside the Event Horizon?

    I greatly appreciate all of your responses. Basically what it comes down to is I have a lot of learning to do regarding General Relativity. Thanks.

    Can Light Orbit a Black Hole Inside the Event Horizon?

    I am most likely beyond my scope of knowledge, but I am under the understanding that an object's orbital velocity required to maintain orbit is less than the escape velocity. In other words, traveling in a direction exactly opposite of the force of gravity originating from the singularity seems...

    Can Light Orbit a Black Hole Inside the Event Horizon?

    The event horizon Wouldn't it be possible for light to orbit a black hole inside the event horizon? In other words, the event horizon, while being a point of no return, is not necessarily a point of ultimate doom.

    Felix Baumgartner and the speed of sound

    My mistake then. I must have overlooked that bit.

    Felix Baumgartner and the speed of sound

    I saw this thread. The speed of sound was more of an after thought, and it wasn't discussed to the extent to how it varies with the medium in which it travels, so I decided to start a new thread. Thanks for the reply. I agree that the sound barrier by which he is measured is the sound barrier...

    Why Did Felix Baumgartner Jump From 128,000 Feet Instead of Going Higher?

    I think it was a matter of Oxygen. Once he disengaged from the pod's life support system, he had about 10 minutes worth of Oxygen. Yeah, he probably could have gone a little higher (assuming there were no other reasons for stopping at 120K which would probably be a terrible assumption), but...

    Felix Baumgartner and the speed of sound

    Doesn't Felix have an advantage when breaking the sound barrier since the air in which he is moving is less dense, therefore the speed of sound itself is considerably slower? (Felix Baumgartner is the man who recently jumped from 128,000 feet in an attempt to become the first man to break the...

    Pushing a car & rolling resistance of tires

    I just want to know if I am understanding this correctly. I am wondering what effect the rolling resistance has on the motion of a car when pushed, or when rolling to a stop. The mass of the car is 1,000kg. I looked up on a table to find the rolling resistance coefficient of a normal car...
