Relativity Paradox

a reply to: Blue Shift

Actually, this effect is observed in the night sky in terms of proper motion of objects or the ejection of gas from cosmic accelerators such as active black holes or active super massive black holes.

If the polar outflows of such an object are pointing toward an observer... but not directly at the observer (for arguments sake lets say 20 degrees off) then the Jet can appear to move (if you select a feature of a jet and track its movement/evolution) faster than the speed of light.

The reason for this is that a relativistic or near relativistic object moving toward you, emitting light, drastically alters the arrival time of the light, since the object emitting it, is moving closer and slightly to the side of the observer.

So for our example of 20 degrees off, if an object is moving toward the viewer, emitting light, it would need to be moving at 0.78c, in order for the transverse velocity to appear to be 1.0c

So that, on this conspiracy site, your comment is not misconstrued as meaning that faster than light phenomena has been observed, here is a quick addition.

If a particle jet 100,000 light years away emits light toward us it will take 100,000 years for that light to get to us. If that jet is traveling directly at us at 99.999% the speed of light, it will take that jet roughly 100,001 years to get to us. So we will see the light from when it left roughly one year before the jet gets to us. But this does not mean it took one year for the jet to get to us, and that it traveled at 100,000 times the speed of light. No. It just means that the light arrives only a small portion of the time earlier than does the jet.

No violations of relativity. No faster-than-light travel. No time travel. No worm holes. Just standard stuff.

Each event is true from within their corresponding frames of reference. There is no definitive truth. You are trying to come up with a universal frame of reference. There is no universal frame of reference.

Exactly. There's no way for a person to "step back" from the universe in such a way that they see more than one outcome or configuration of spacetime. It's a fantasy created by deficiencies in the mathematics in the same way spaceships in old video games would vanish off one side of the screen only to appear from the opposite side. That doesn't happen in real life. The same attempt to apply non-POV math to the real world results in these "paradoxes," which don't really exist.

circumstances of the observer collapse the wave function in unique ways.

we are never limited to one or two outcomes unless we create the outcome ourself in a closed environment and even then keeping out reality is just a matter of chance at best.

Good shout sir! sometimes forget where I am commenting

Newton once said "There are three sides to every story: A's version of events, B's version of events, the correct version of events"

Einstein said "There are two sides to every story and they are both correct."

They didn't really say that. I'm just being silly.
