    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    I'm sorry Vanadium, not trying to make enemies here. I'd like to get to the point and get an answer, but not sure of the best way to get my answer without getting shredded or misunderstood.

    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    I said "unconventional use". Seems like you're stuck in particularly granular set of rules prescribed by an extensive knowledge of physics. Let's back out for a sec, and just run the formula.

    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    No argument here, just not the point of my query. That's pretty much the question. Take a look at Dale's response. Fair enough, I was writing in short hand. I'd be happy to expand on the thought experiment if you would entertain it. I'm really just looking to learn here, but in order to get...

    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    YES! This is what I'm talking about Dale! The S Metric does something really interesting. The more mass you throw at it, the larger and less dense said "black hole" becomes. In other words, the more mass you have, the easier it is to arrive at a net total gravitational force that bends light...

    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    The entire premise exists outside the confines of our planet, the solar system, even our galaxy so I'm not sure how tidal forces are a thing. In empty space would the principles of equivalence not apply? That's what I'm referring to. As I mentioned to Peter, we may be missing the point here...

    Equivalence principle applied. Get in your elevator on this one please ;)

    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    I love how certain you are of things so far out of reach Peter :) I think you're missing the point of my query. This is a thought experiment and I have a question about its validity. I may not be using terminology in a scientifically exacting way (as you pointed out) because this is a forum...

    B Calculate Red Shift w/ Shwarzschild Metric: A Hypothetical Black Hole Any Size?

    You can unconventionally use the Shwarzschild metric to calculate red shift at given stellar distances with some accuracy right out to the edge of the universe. Take the mass of the known universe ~10^55kg. Try it! A bit ironic. I understand this is not how to use the Shwarzchild; however...

    Energy shift in a photon passing by a gravitational well

    Hey Simon - I agree with you (also I know EMR doesn't slow, was a slip of the tongue). The last math class I took was high school algebra so basically everyone on here has me beat. I apologize for my lack of experimentation. I'm in a cosmology for dummies class at Harvard Extension (yes...

    I'm standing on a black hole, is light approaching red or blue?

    no bang Humans have a history of being geocentric (egocentric) when it comes to physics. We've created a model where, by admitted limits in instrumentation, we find ourselves ironically smack in the "center" of a giant expanding balloon of space where 13.77 billion years ago there was some...

    I'm standing on a black hole, is light approaching red or blue?

    There's a paradox in that the universe appears to be infinite although according to big bang / cosmic inflation it's limited in age. Personally (and I am an extreme minority here) I don't like big bang / inflation. Soooo many paradoxes that require very complex physics to resolve. This is...

    I'm standing on a black hole, is light approaching red or blue?

    Obviously Schwarzschild metrics get far more complicated such as that of a spinning black hole, however in the most simple sense it seems to say that the mass of an object will affect the path of light. An object is what? A cluster of gravitating constituents. So just as our bodies are made of...

    I'm standing on a black hole, is light approaching red or blue?

    HA! If you calculate the Schwarzschild radius of the Mass of the visible universe (roughly 10^80 atoms or 10^55kg) you ironically get its age equivalent. rs=2GM/c^2 (rs=schwarz, G is Newtons G constant, M=mass). Done my own calc, but below is from Wiki. "The Schwarzschild radius of an...

    I'm standing on a black hole, is light approaching red or blue?

    Schwarzschild and Pound-Rebka The Schwarzschild gets exponentially bigger the more mass you pump into the hole. For example, our universe of 10^55kg (give or take an exponent) has an event horizon roughly approximate to its age, and yet we don't consider the universe a black hole. Seems to...

    Energy shift in a photon passing by a gravitational well

    What about the Shapiro delay? http://en.wikipedia.org/wiki/Shapiro_delay If EMR passing a massive object slows down, does that not constitute a loss of energy?
