AI Thread Summary
To determine your exact speed and direction in the universe, one can measure the time differences in light reaching you from a source as you move towards or away from it. The speed of light remains constant, allowing for calculations based on these measurements in the x/y planes. The universe lacks a preferred frame of reference for measuring velocity, making all inertial frames equally valid. A common approach is to establish velocity relative to the Cosmic Microwave Background, which averages the momentum of radiation for a rest frame. This understanding aligns with the principles of Einstein's theory of relativity and the findings from the Michelson-Morley experiment.

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.
 
This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
