Phi for All Posted April 17, 2017 Share Posted April 17, 2017 Basically, what I am getting from this, is that I am wreckless with numbers and firm with ideas. I'll admit my mathematics are completely off base. So perhaps not as "firm" with the ideas as you thought before? It would be difficult to have a firm grasp of anything without knowing the basics well. Like assuming you could think outside the box without knowing what's inside. 1 Link to comment Share on other sites More sharing options...
Manticore Posted April 18, 2017 Share Posted April 18, 2017 Satellites that are further away actually travel slower. The International Space Station has a Low Earth Orbit, about 400 kilometers (250 miles) above the earth's surface. Objects orbiting at that altitude travel about 28,000 kilometers per hour (17,500 miles per hour).Jan 17, 2013 But you said "Differently weighted things need to travel at different speeds to stay in orbit" which is bollox. 1 Link to comment Share on other sites More sharing options...
Strange Posted April 18, 2017 Share Posted April 18, 2017 The number that this equation spits out fits on an inverse square, according to this knowledge But you don't even have a power of 2 in your "equation" so it i not an inverse square. So I assume what you really mean is: [latex]P \propto \frac 1 {{energy}^2}[/latex] But, of course, it is impossible to calculate P from this because it is not an equation. So what you really need is: [latex]P = \frac k {{energy}^2}[/latex] Where k is some (unknown) constant of proportionality. However, we know from experiments that such an equation is wrong. In the vicinity of a non-rotating massive spherically symmetric object (e.g. the Earth) time dilation is described by: [latex]t_0 = t_f \sqrt{1 - \frac{2GM}{rc^2}}[/latex] https://en.wikipedia.org/wiki/Gravitational_time_dilation And this is confirmed by experiment, including GPS satellites. 1 Link to comment Share on other sites More sharing options...

You claimed that satellites of different mass must travel in different orbits, and thus at different speeds (but ending with the same KE) which is utter nonsense. 2 Link to comment Share on other sites More sharing options...
Strange Posted April 18, 2017 Share Posted April 18, 2017 Basically, what I am getting from this, is that I am wreckless with numbers and firm with ideas. I need to be slower with this, and check my shit twice before I throw numbers. If you use Wolfram Alpha you can type very high-level calculations. For example, if you want to calculate the energy equivalent of the mass of the Earth, just type "mass of earth * c^2": http://www.wolframalpha.com/input/?i=mass+of+earth+*+c%5E2 This will give you 5.367544 x 1041 J And note that if you ask for the answer in watts ("mass of earth * c^2 in watts") it will tell you that you can't do that ("the results are not compatible"). 2 Link to comment Share on other sites More sharing options...
Argent Posted April 18, 2017 Share Posted April 18, 2017 Basically, what I am getting from this, is that I am wreckless with numbers and firm with ideas. Unfortunately, while you are reckless with numbers, your numbers are nothing but wrecks that have happened, are in the process of happening, or are about to happen. This leads the reader to believe that you don't know what you are talking about. 1 Link to comment Share on other sites More sharing options...
imatfaal Posted April 19, 2017 Share Posted April 19, 2017 ! Moderator Note Ok - this thread has run its course. It is abundantly clear that the OP has scant understanding of the basics of mathematics, physics, and cosmology - we do not provide this space for people to blog their latest fantastical pipe dream. The speculations forum exists to allow members to test their idea - but these tests necessarily rely on compatibility with current theory, mathematical consistency, and the possibility of empirical evidence and comparison to the data; this speculation does not even allow the possibility of such testing. This thread falls well below the standards required for the Speculations Forum and is now locked. The OP does not have permission to reopen a new thread on the same topic. 1 Link to comment Share on other sites More sharing options...
