SUMMARY

This discussion explains how to determine the exact speed and direction of an object moving in the universe, emphasizing the constancy of the speed of light. By measuring time differences in the x/y planes, one can calculate the velocity relative to a stationary frame, such as the Cosmic Microwave Background. The conversation references the Michelson-Morley experiment, which demonstrated the absence of a preferred frame of reference, supporting Einstein's theory of relativity. The discussion highlights the importance of relative motion in understanding universal dynamics.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with the speed of light as a constant
  • Basic knowledge of coordinate systems (x/y planes)
  • Awareness of the Cosmic Microwave Background
NEXT STEPS
  • Research the Michelson-Morley experiment and its implications for physics
  • Study the principles of Einstein's theory of relativity in detail
  • Learn about measuring cosmic velocities relative to the Cosmic Microwave Background
  • Explore advanced concepts in astrophysics related to universal motion
USEFUL FOR

Astronomers, physicists, and students of relativity who seek to understand the dynamics of motion in the universe and the implications of relative velocity.

How To Determine The Exact Speed You Are Moving In The Universe


This should and will be able to show exactly how fast and in what direction
the planet and all of its inhabitants are moving in the universe.

If a light source is in front of you and you are moving in the universe towards
the light then you should reach the light faster.
As fast as you are moving in the universe towards it.

The same would be true if you are moving away from the light source.
The light would have to travel however much farther to reach you.
.
.

Since the speed of light is a constant, by taking measurements
in the x/y planes you can find the differences in time, and be able to devise the exact direction and speed that the object is moving in the universe.

example:

y+.6
x-.2 (o) x+.2
y-.6


The movement of this object in the universe, if this were the case, would be
down and slightly to the left in this orientation.

The universe does not have a preferred frame of reference from which to measure our velocity. All inertial frames are equally valid. Once thing we can do is say we have a velocity relative to a frame that is at rest relative to the Cosmic Microwave Background. But even then we are merely averaging the momentum of the radiation and coming up with a rest frame.
 
While Drakkith is right, it's exactly your line of reasoning and Mikelson-Morley coming up with a way to measure this that allowed us to realize that there is no preferred frame of reference to measure our velocity ... and to Einstein's theory of relativity.
