I am reasonable. I am rational.
I'm not banned because I'm not an idiotic fucktwit that parades around pretending to be better than everyone else by posting half-reasoned scientific questions by today's knowledge standards.
2) You're trolling because your political stance was not even a part of this topic, but you announced that you hold a particularly unpopular opinion on here which was irrelevant to anything said.
3) Idiots vote for Idiots, especially twice in a row - jus' sayin'.

Even then, my batting average is pretty high. It can take a hit.

General discussion forum?
Clearly, this is the League of New Age Atheists that are trying to re-label themselves as "reasoned", "rationalists", because apparently, one is only reasoned or rational if they are an atheist.
Talk about a false dichotomy.

LoL! You half understand it and then claim that it actually supports your view?

Who do you take me for?>< V >< said:Do you really expect someone like myself that has dedicated their life to physics, to advancing physical knowledge, being a true promoter of correct science, to treat someone like Master_Ghost_Knight as an intellectual equal?
Master_Ghost_Knight said:To my own frame of reference at the time of measurement.>< V >< said:Mister 1609 posts in the League of Reason, you clearly do not understand the difference between Newtonian mechanics and Einstein's relativity. You "think" you have zero velocity sitting in your chair, but compared to what?
Erh.. no! But for sake of argument they are very close and let's just say that it is.>< V >< said:You are using the reference frame of the Earth.
In what frame of reference?>< V >< said:But the Earth has a velocity around the Sun.
In what frame of reference?>< V >< said:The Sun has a velocity around the galactic center.
In what frame of reference?>< V >< said:And the Milky Way galaxy has a velocity around the other galaxies in the universe.
You are not very good at this are you?
>< V >< said:You say something can be at rest, but in doing so, you have chosen some reference frame to say the object is at rest in. As you sit in your chair, you are not at rest, but moving through the universe.
Wait isn't this an objection that implies that there is an absolute frame of reference?
And when you say:
You are kind of contradicting yourself. And given that the latter is not yours but actual physics, aren't you kind of wrong?>< V >< said:One of the monumental breakthroughs from Einstein was proving that there is no absolute reference frame.
Do you even understand why I had to put "at the time of measurement" condition?
What? You just bypassed every single question and throw in yet another red herring as if I wouldn't notice that you haven't touched any of it?>< V >< said:Newton's second law, when mass is constant, is F = m*a. Force equals mass times acceleration. If an object has no acceleration, then it has no net force.
There is no "centripetal" force in a orthonormal coordinate system, to have a "centripetal" force you must either use a cylindrical or spherical coordinate system, and the problem with this is that it presupposes a reference frame centered on the pole (not pole as in north and south pole, but a mathematical pole).>< V >< said:Since velocity is a vector, constant motion means, constant motion in a straight line. But constant circular motion requires the velocity vector to change directions and since acceleration is defined as a change in velocity over a change in time, even though the "speed" may be constant, if the velocity vector changes direction, then there must be an acceleration. This acceleration is called centripetal acceleration and can be equated to (tangential velocity squared)/(radius of motion).
No, this is what they teach you in high school. And I agree, it is to simple.>< V >< said:As you sit in your chair, in the simplest of pictures, your net force is zero, you have no acceleration and you are at rest. This is what freshmens are taught. But this is NOT the whole picture of physics.
What this is still high school level physics, and it also happens to be wrong, you can no longer simply invoke the centripetal acceleration to explain the net motion of the objects because you have tangential accelerations as well. Plus it is highly stupid to make the calculations in a spherical coordinate system because the masses of galaxies can be comparable (like the Milky Way and Andromeda) and you have no non-accelerated frames and thus it would not help you at all, in fact it would only complicate the problem. You can still do it, but it is just dumb to do so.>< V >< said:This is the beginnings of understanding something more complicated, because obviously, as you sit in your chair, you orbit the Sun. You orbit the galactic center. You orbit other galaxies. And orbiting another object demands a change in your velocity vector, demands a centripetal acceleration, which demands a net force. A net force due to gravity.
Again more high school physics, and again wrong. Because you are still thinking in terms of the one body problem. You can still have gravity and yet no net force of gravity and no net acceleration given that the force is balanced out by other bodies with mass, true that it is unstable and impractical to achieve perfection but that doesn't change the fact that you can have that. In fact a derivative of this property is the main principle behind the fixing of the Soho satellite. And not all objects are under the orbital influence from each other, it is true that gravity from distant galaxies still reaches us it is not true that that we orbit them or vice versa. This is because at larger scales the universe no longer resembles the massive concentrated objects separate by vast empty space but it is rather a fog of super clusters each more busy being under the local gravitic influence and space expansion then actually going around a distant galaxy making an effect smaller than noise. In fact it is possible that there are galaxies beyond our local horizon, that because they are so far that the expansion of space supersedes the speed of light, their gravitic effect will never be felt at all and they might as well not even exist.>< V >< said:Since the gravitational force is only zero at infinity and the universe is not infinitely large, means all objects in the universe are in orbital motion due to a net force from gravity. Thus, all objects in the universe have, at least, a tangential velocity. And if all objects have a velocity, then no object is at rest.
Except when you say shit like "tangential velocity", "centripetal acceleration", "radius of motion" and stuff of that sort which can only exist on reference frames.>< V >< said:Notice that no where do I need to refer to a frame of reference.
No, it doesn't do that at all, nothing in the "Einstein's four dimensional universe" claims that there is no center of the universe, what it spouses is that the laws of physics are the same anywhere in the Universe in any frame of reference. And Newtonian physics did not require a center to the universe to have an absolute frame of reference. As far as I'm concerned the 2 are completely unrelated.>< V >< said:What Newton wanted to believe (but himself admited was not well established) was that there was a center to the universe, of which all objects orbited. And this "center of the universe" was the absolute reference frame of which all objects could be measured against.
But in Einstein's four dimensional universe, there is no center. With the elimination of the center of the universe, was also eliminated Newton's only hope of an absolute frame of reference.
So you mean you can? How tell me then, I will forward you to the Nobel Prize in physics for disproving relativity, because one of the principle of relativity is that you cannot devise any experiment in which you can tell absolute time. What you call "proper time" is in fact the time according to a predefined frame of reference of my choosing. If I perform a certain path in reference to A, in my clock I will measure a time, if I ask for the proper time I asking how much time has it been in accordance to a clock on A.>< V >< said:You mean, you don't know? You don't know introductory special relativity, while you sit here and make comments challenging special relativity?Master_Ghost_Knight said:I'm curious to know how you measure proper time.
It is both. And to explain that I would have to answer the question which I have posed to you and you have yet refused to answer. This one:>< V >< said:How do you answer this contradiction you have put forth?
Master_Ghost_Knight said:The right answer is, for you time allways "flows" the same from your prespective no matter in which reference frame you areSo on one hand, time always flows the same, yet, on the other hand, if I sit in a satellite, time runs slower. Which is it?Master_Ghost_Knight said:But yes the fact that clocks run slower in orbit is an observable fact, and that experiment is continuously being performed by satellites in orbit.
If you know the answer to that, then you should know why it is not a contradiction. But of course you think it is a contradiction and you don't know the answer to that.Master_Ghost_Knight said:Do you even understand why I had to put "at the time of measurement" condition?
Master_Ghost_Knight said:YES!!!!!!!!!! That is what your equations say, that is what space time means!>< V >< said:You can replace time with space?
No, THIS is what you said:>< V >< said:That is not what I said. This is what I said.
Which means exactly what I said. You can argue what you like, the equations don't lie.>< V >< said:ds^2 = dx^2 + dy^2 +dx^2 -(c*dt)^2
That would be V=dr/dt not v=d/t>< V >< said:Velocity is defined as the displacement vector divided by the change in time, v = d/t.
Except of course you forgot the scale factor C. It should be read V=d(T*c)/dt, since C is a constant you should have V= C*dT/dt. So lets do the unit analysis, to aid the view lets use SI units. V[m/s]=C[m/s] dT>< V >< said:According to you, space and time are interchangable and thus velocity can also equal v = t/d, which is obviously wrong. Clearly, unit analysis alone should dictate that.

Dean said:???Leà§i said:The title seems self-explenatory. Does time go at the speed of light?
Try: Doestimeobjects travel through time - at the speed of light?
= Yes.
Objects in the universe apparently move through time at the speed of light, though not necessarily through space at the same rate. It's indeed an extremely bizarre concept to grasp, but I have heard this from serious cosmologists.
I recommend this BBC Documentary presented by the articulate Professor Brian. Cox:

Master_Ghost_Knight said:But since you are such an expert on Newtonian gravity, there is a sort of a question that I tend to put to people I suspect to be bullshiting. Tell me using Newtons equation for gravity:
F=G*M*m/(R^2)
And lets imagine that you have a cluster of asteroids with total mass M whit a center of mass on point P.
And this is what I want you to do. You are going to tell me in which coordinate system is the force of gravity expressed in. You are going to select an arbitrary geometry for the distribution of the asteroids with a number not lower than 4, you are going to select an arbitrary geometry that encompasses all asteroids and tell me the expression for the flow of the gravitic force for the geometry you chose.
Fortunately this is not easily found on the web (which is where I suspect you get your knowledge from), if you can give me the right answer then I will not dismiss the next post you make as the ramblings of an ignorant baboon. If you are not able to, then consider yourself busted and you can crawl back to the cave which you have come from.

Hytegia isn't an atheist. Which pretty much pwned your whole argument. In other words, a failed ad hominem remark. Deal the fuck with it, I say.
