    I Volume vs Circumference of Massive Body

    I had another though on this... In the common examples of time and length warping, it is commonly explained that if a car wizzed past me at relativistic speeds, we would see the car greatly shortened and the clocks inside the car running slow. To the person inside the car, he would see his space...

    I Volume vs Circumference of Massive Body

    Thanks again for the input/s. I understand the concept of non Euclidean spaces (although not in enough detail to do volumetric calculation) and I have worked through 3D vector calculus, although many many years ago now. What caught my attention is that he clearly calls out that the diameter of...

    I Volume vs Circumference of Massive Body

    Thanks again. Space in my post is more properly the idea of volume. I don't know if that makes a difference or not, but that was my intended meaning. I am still trying to understand the consequences of the larger diameter so bear with me please. Say we use the sun example so we don't have to...

    I Volume vs Circumference of Massive Body

    Thanks Peter for your reply and I her your "No's". I am trying to reconcile some information in Kip Throne's videos on youtube. In the following two videos.. from 22:05 to about 23:30 from 12:05 to about 12:48 In these videos he explains the warping of space, one for a black hole and a...

    I Volume vs Circumference of Massive Body

    Thanks. With this idea, I get the image that there is more space at my feet than at my head (however so small), and its as though I am falling into that larger space, or pushed into that larger space, because of this space gradient. So instead of thinking as gravity as a force pulling me down...

    I Volume vs Circumference of Massive Body

    Volume vs Circumference of a massive body. In the spacetime diagrams it is often shown that the space around massive bodies is warped in a way that seems to indicate the actual volume of a massive body is larger than 4/3 pi r^3. If you measure the radius from the circumference by traversing it...

    SpaceTime... Why can we access past but not future events

    If general relativity, space and time are postulated as a 4D non euclidean space that exist absolutely. All past, present, and future events are static moments in this model. In this model, the present moment can access and has knowledge of past events, but cannot access or have knowledge of...

    Is the wave function more like a soccer ball, or a golf ball

    I have been trying to understand the wave function around an atom.. Is it more like a soccer ball where the shell is smooth but is more likely to be found in say the dark areas, or is it more like a golf ball where it is not only angularly undulating, but also radially undulating?

    If the local is defined as the 'Hubble radius'

    Thanks for the replies... I appreciate the patience on this forum.

    If the local is defined as the 'Hubble radius'

    I have great trouble with the concept of 'local' as it seems very generic in ways. Local can be a plank distance away, or a meter away.. or even a Hubble radius away (if your scale is in Hubble radii (sp) or so). If distance in the direction of travel approaches zero as velocity approaches the...

    Will the Earth Observers See a Burning Spaceship?

    I had this though back in collage and asked my professor and he gave me a very short attempt to answer the question then said he was never quite sure about all this relativistic stuff... I didn't get my answer though but I have not forgot my question. Say a spaceship was headed toward the sun...

    Free Fall vs accelerated reference frame question.

    Ya, that helps. I was reading on wiki the following.. http://en.wikipedia.org/wiki/Equivalence_principle The Einstein equivalence principle[edit] What is now called the "Einstein equivalence principle" states that the weak equivalence principle holds, and that:[32] The outcome of any local...

    Free Fall vs accelerated reference frame question.

    ah... so even two accelerometers 1cm apart violates local? I get 'local' now. Thanks!

    Free Fall vs accelerated reference frame question.

    Ya, that adds a wrinkle. Say remove the propulsion component, would a gravitational tidal gradient always be present? I am thinking yes as while we can construct an idealized local uniform gravitational field, with infinite precision instruments, we would always find the gradient at some x...

    Free Fall vs accelerated reference frame question.

    I meant to add this idea as I knew it would be mentioned. I do understand the energy vs observer component. The guy in the yard can know the real situation, but the guy in the sphere cannot know. He cannot know if he is moving or stationary on a massive body. However, the gravitational tidal...
