As you set down, how fast are you actually moving?

[Robert W]

First Earth: So, Earth travels about 1.6 million miles (2.6 million km) a day, or 66,627 mph (107,226 km/h).

So, even as you sleep, you move at an astounding speed day and night.

The Earth keeps pace with the Sun and moves around it.

How fast is the Sun moving. You might not believe it, but you are moving with the Sun faster.

The Sun is moving through space at an average speed of around 450,000 miles per hour(720,000 kilometers per hour) as it orbits the center of the Milky Way galaxy, carrying the entire solar system with it; this means it takes roughly 230 million years for the Sun to complete one full orbit around the galaxy.


Key points about the Sun's movement:

• Speed:Approximately 450,000 miles per hour
  
  
  
• Orbit:Around the center of the Milky Way galaxy
  
  
  
• Time to complete one orbit:Around 230 million years

To be honest Rob, the only thing i do fast these days is fall asleep after din din.....

Well, that is true:

• The Earth is spinning (rotating) on its axis (day/night)
• The Earth is revolving around the sun even faster (our seasons)
• The entire Sun and solar system is but one star in the Orion Arm slowly orbiting (and bobbing up and down) about the Milky Way even faster.

But what you left out is that the Milky Way is itself in motion. It and other galaxies in our Local Group (including the Andromeda Galaxy M31 and the Triangulum Galaxy M33 are all hurling (as best as we can tell) in the direction of Hydra (low in the southern sky on a Spring night) being drawn by what we call The Great Attractor, at a speed faster than about 1.3 million mph.

But that begs the question:

If all the galaxies are whirling about the universe, how fast is the universe itself moving? It stands to reason that the universe itself is in motion, at even far higher speeds! The problem is in motion with WHAT? We have no way and no context in which to measure that motion as it would likely be in motion with another universe, but there is no way of telling for sure since we cannot even see the outer limits of our own universal boundaries.

I'm not convinced that redshift alone at such extreme distances is a reliable arbiter of speed or distance.
I'm of the opinion that the universe itself, space or the curvature of space contributes to the effect.
Possibly even dark matter.

Put another way, beyond a certain point, redshift becomes an optical illusion/distortion like looking at fish in a fishbowl.

Interestingly, RW, the physics of it suggests that speed and motion are essentially meaningless and non-different---- that everything is both in motion and stationary at the same time, and that in one frame of reference, we could be moving at superluminal speeds, yet in other frames, be standing still, that there really is no difference, that what really matters is the FRAME within which one measures oneself to.

Also interesting is that no matter how big or small one looks, everything everywhere is in motion, atoms are in motion, electrons are in motion, even quarks are in motion. In fact, the main thing which defines the difference between energy and matter is--- motion. Energy cannot exist below the speed of light nor can matter exist above the speed of light.

Things that really floored me is the speed through space of the Sun that we are moving faster in order to circle the Sun. What kick started this massive movement? Do any stars exceed the speed of the Sun?

Things that really floored me is the speed through space

But like I said, space is an empty vacuum, so speed is irrelevant. Our true speed can be unknown and we can only measure it in relation to the relative motions of other bodies. For instance, do you know that the Andromeda galaxy is flying towards us and in the far distant future, it and our Milky Way will collide? Then the two galaxies will be disrupted by tidal interaction and cease being spirals. They will eventually combine into a massive irregular galaxy, and I must assume eventually organize into a big elliptical or maybe form an even larger, new spiral again.

of the Sun that we are moving faster in order to circle the Sun. What kick started this massive movement?

Believe it or not, the exact same force as causes your bath water to spin as it goes down the drain. Beyond that, the explanation goes deep into statistical mechanics and dark matter.

Do any stars exceed the speed of the Sun?

Of course. Some are moving MUCH faster. There are random stars shooting across the sky. Barnard's Star you can see in a pair of binoculars and is moving so fast that in less than 200 years moves so far across the sky as about the diameter of the full moon. Other stars had close calls or were ejected from an explosion or something and may be flung clear out of the galaxy. Stars close to the black hole at the center of the galaxy are moving so fast in the gravity well of the black hole that every few years taking pictures of the area, they can be seen moving in their orbital paths!

Some stars have been clocked moving several million mph in relation to the other stars around them.
