Nicholas Posted July 9, 2005 Author Share Posted July 9, 2005 Motion in the universe is absolute. In relativity it is known as "closing velocity." There is no problem calculating the absolute motion at any given point of the Earth around the Sun now is there? At any given time there is an absolute distance between them now isn't there? You know what no absolute rest means? It means everything in the universe is moving through space. Link to comment Share on other sites More sharing options...
ydoaPs Posted July 9, 2005 Share Posted July 9, 2005 that isn't absolute. you are using the earth and sun as reference points. no absolute rest just means that no one is justified in saying "I am at rest." it just puts everyone on equal footing.

The distance between the sun and the earth depends on who is doing the measuring. It is therefore not an absolute. Link to comment Share on other sites More sharing options...
insane_alien Posted July 9, 2005 Share Posted July 9, 2005 to determine motion you need to relate it to something else. whether that something else is in motion or is at rest is irrelevant as you are seeing motion relative to the something else. no experiment has yet been concieved or even hinted at to be possible that could determine if an object is moving without reference to something else.

Nicholas Posted July 9, 2005 Author Share Posted July 9, 2005 The distance between the sun and the earth depends on who is doing the measuring. It is therefore not an absolute. We can all agree on the distance between the sun and earth. For people on the earth the suns distance is an absolute. There is a time when there are no relatives. And you know what time that is? When there is no motion. Link to comment Share on other sites More sharing options...

The distance from the earth to the sun is an absolute. Do you know why? The invariant space-time interval is the proof of an absolute space-time.

Silly dad ok, here we go. you are in a spaceship and feel no acceleration. you and the solar system pass each other. that means you cannot tell who is moving, you or the system. and with that, you see the distance between the earth and the sun to be less than what a person on the earth would see. now how is that distance absolute?

Nicholas Posted July 9, 2005 Author Share Posted July 9, 2005 Dad? But there is never a time when the spaceship that has been propelledf(accelerated) will not experience weight during that propulsion. Moving through space(due to acceleration) is an absolute. And the relatives only exist in potential to these absolutes. Link to comment Share on other sites More sharing options...

JaKiri Posted July 10, 2005 Share Posted July 10, 2005 For people on the earth the suns distance is an absolute. You're standing by a lift door on the 6th floor of a building. I'm in the lift' date=' travelling upwards, and I pass by the 6th floor. Even though we are in close physical proximity, the distance from me to the sun will be different from the distance from you to the sun, because I'm travelling at a different relative velocity, and the ratio between them will be SQRT(1-v^2/c^2). That is, as far as we can gather, [b']true[/b]. However, it disagrees with your assertion that there is an absolute distance from the earth to the sun. Therefore, your assertion is incorrect. Can you please stop posting self-contradictory ("It's an absolute distance, if you measure it relative to other things!") guff, especially when you're trying to argue with what may be the most supported theory in the history of science?

HeHe. Moving through space is absolute(closing velocity). And if there is no motion there are no relativistic effects. Link to comment Share on other sites More sharing options...
ydoaPs Posted July 10, 2005 Share Posted July 10, 2005 saying "moving through space is absolute" doesn't make it true. you have yet to provide any proof or even circumstantial evidence for your claim. you haven't even given us clear logic to arrive at your conclusion. edit: read this http://www.scienceforums.net/forums/showthread.php?t=11529 Link to comment Share on other sites More sharing options...
