How fast is the universe traveling through space?

If the big bang is true, then the galaxies must all be traveling outward at roughly the same pace… But what is that pace? Clearly it must be extremely fast.

…if there was an object that was motionless in space, would it cut our universe like a knife? Clearly, science doesnt believe the big bang acted like a roman candle spitting things out, right…? Surely it was more like stack of dynamite blowing outward in every direction at once.
 
If one could imagine the universe as projectiles flying out from a perfect sphere, then are all sides of that sphere traveling outward at an equal pace? Id say that if one side was faster, or if the top and bottom were faster, then that would indicate that a simultaneous explosion didnt actually take place. It would indicate a collision.
 
I hope I don’t sound rude, but I think such a question should be asked in another forum, possibly another site.

All i can say is, reading your title, I was confused, because the universe isn’t travelling, as it is all that exists. It is expanding.
For the rest of your points, i must pass.

To find the correct answer there is a multitude of astronomy sites ,
With various forums ,most of which are very informative,
It’s great to see your curious about these things,
Education and knowledge are the best defence against the uneducated

This is not the current view of the science community. The big bang, as understood now, has no center. The relative distance of all galaxy clusters are equally increasing. Here a nice explanation:

However keep in mind that this is an ever changing subject that has still a weak foundation.
 
Note that the surface of a balloon is a finite area with no boundary. The universe a finite volume with no surface. The basic evidence for the Big Bang is a flux of radiation coming from every direction. Whichever way one looks one is looking toward the center from which it expanded.

The speed at which distant galaxies are moving away from us is proportional to their distance from us.

Hmm, so is the universe not a sphere then either? If every direction points to the center then has some sort of dimentional phenomena taken place?

What shape is the universe then, if every direction points toward the center? Is it a two-dimentional phenomena, like only the skin of a balloon? Or is it three-dimentional, like a sphere -which includes the volume of gas within the skin of a balloon?

The expanding balloon is a good analogy. But for it to work, the three dimensional universe must be thought of as equivalent to the surface of the balloon. In other words, if you were to travel in a straight line in any direction at all in the universe, you would traverse what amounts to the surface of an expanding balloon and arrive back at your starting point, just like circumnavigating a globe. So the universe can be thought of as spherical, but as a 4-dimensional sphere, since the three dimensions we experience are the surface of the expanding sphere.
 
…answer this: two equal cars traveling at equal rpm’s, one goes east and the other goes west. Which one is moving faster? 🙂
