13. And here’s you from just beyond Neptune, 4 billion miles away.

To paraphrase Carl Sagan, everyone and everything you have ever known exists on that little speck.
14. Let’s step back a bit. Here’s the size of Earth compared with the size of our sun. Terrifying, right?

The sun doesn’t even fit in the image.

Let me try to clarify my point. You have a chain, it is 10 ft in length and has 26 links, we will asign a letter to each link and each link is a frame of reference. So we have the first link A and the last link Z. Now in terms of the universe both the length of the chain and the number of links would be infinite.
If you were to whip this chain the relative motion of link A and Z would exceed the speed of light on the scale of the whole universe, but in fact you are not an observer of the entire chain, you are an observer from let's say point D, now the chain can only physically accelerate to the speed of light, each link traveling away from the other at the speed of light in a perfect synchronistic sequence when it is whipped. So as far as the relative motion of each observable link is concerned no nothing exceeds the speed of light.

15. And here’s that same sun from the surface of Mars:

16. But that’s nothing. Again, as Carl once mused, there are more stars in space than there are grains of sand on every beach on Earth:

17. Which means that there are ones much, much bigger than little wimpy sun. Just look at how tiny and insignificant our sun is:

Our sun probably gets its lunch money stolen.

18. Here’s another look. The biggest star, VY Canis Majoris, is 1,000,000,000 times bigger than our sun:

19. But none of those compares to the size of a galaxy. In fact, if you shrank the sun down to the size of a white blood cell and shrunk the Milky Way galaxy down using the same scale, the Milky Way would be the size of the United States:

20. That’s because the Milky Way galaxy is huge. This is where you live inside there:

21. But this is all you ever see:

(That’s not a picture of the Milky Way, but you get the idea.)
22. But even our galaxy is a little runt compared with some others. Here’s the Milky Way compared to IC 1011, 350 million light years away from Earth:
Via Twitter: @smokeinpublic
Just THINK about all that could be inside there.
23. But let’s think bigger. In JUST this picture taken by the Hubble telescope, there are thousands and thousands of galaxies, each containing millions of stars, each with their own planets.

24. Here’s one of the galaxies pictured, UDF 423. This galaxy is 10 BILLION light years away. When you look at this picture, you are looking billions of years into the past.

Some of the other galaxies are thought to have formed only a few hundred million years AFTER the Big Bang.

25. And just keep this in mind — that’s a picture of a very small, small part of the universe. It’s just an insignificant fraction of the night sky.

26. And, you know, it’s pretty safe to assume that there are some black holes out there. Here’s the size of a black hole compared with Earth’s orbit, just to terrify you:
THE END!

I read like two pages and already my brain hurts.
But here's pic of some nice sempervivums for a little levity

I think you would need to define 'we'; do you mean Earth only, our solar system, our part of the Local Group, or our galaxy? Then you would need to be specific on which galaxy (or other object) whose motion you would like to compare to our own. Even with those data, I don't think there is anyway you could calculate what you're asking. Remember that the light from the galaxies we can see from that distance is billions of years old, a lot of those galaxies that we see have not existed for a long time so we'd be measuring against a ghost in those instances. Also, take these facts into account: the universe has no edges and no center. That should fry your brain a bit. We can tell from the color shift if an object is moving away or headed toward us, and at what approximate relative speed. We also know that the universe is not only expanding, but its expansion is accelerating. And not only is spacetime itself expanding out into... whatever... but the space in between objects is also expanding... and accelerating. In about 10,000 years we won't be able to see any light from the sky save for our very local group. Just blackness for the most part, so we're very lucky to have lived in the time we have. Future astronomers of other sentient species (assuming there are other sentient creatures) will likely come up with the general makeup of our cosmos via math and the laws of physics, but we got to actually witness it. Good timing. As for asking if we (our planet?) are approaching light speed, I'd have to ask relative to what? Since space is expanding and dark energy is pushing all objects apart from one another, our relative speed is constantly accelerating, but it makes no difference from our perspective as we cannot feel it. Regardless, faster than light travel is not possible for objects with mass. There are no implications of time travel from our perspective, regardless of our relative acceleration...

I just finished reading Mobius' articles on quantum biology. Holy fucking shit, was that challenging for me to understand. It took hours to get it all straight. Fascinating stuff. I will give my impressions and opinion on its implications soon. Hopefully tomorrow...

How fast is our galaxy moving relative to the most distant galaxy?
But this is a tricky question, because there is the observable universe, and than there is the universe we can't observe.
I would assume that all of the galaxies in the observable universe are not moving away from our galaxy faster than the speed of light, because we would not be able to observe it: but what about the most distant galaxy in the "unobservable" universe? I am sure that even an astronomer can't answer this question, but it should be interesting to ponder.
Also, here is another question that I don't know the answer to: how many galaxies are in the total universe, including the galaxies that we cannot observe? Does the universe go on forever? or is there an end to how far the galaxies reach? Hypothetically speaking, is the multiverse an infinite amount of universes that go on forever and ever, or is there an end to the multiverse.
Thats enough mind boggling questions for now, and anyone can give Me a rebuttal, not just tyler, because I would like to hear different opinions too.
Thanks.

When we put all three of these things together, what we get is the concept known as eternal inflation. The big idea is that what we call “our Universe” is just one place — which we can only see a part of — where we’ve successfully slid down the hill. But the vast majority of the “true” Universe, outside of our little pocket, is still inflating, and still expanding exponentially!
Based on what we currently think about inflation, this means that the Universe is at least 10^(10^30) times the size of our observable Universe! And good luck living long enough to even write that number down. Thanks to Rob Knop for making me think about this, and isn’t that a mind-blowing thing to think about? All that we know, see, and observe is just one tiny region that slid down that hill fast enough to end inflation, but most of it just keeps on inflating forever and ever. Aren’t we the lucky ones?!

A quick Google search yielded this info -
According to the best estimates of astronomers there are at least one hundred billion galaxies in the observable universe. They've counted the galaxies in a particular region, and multiplied this up to estimate the number for the whole universe.

Infinite:
Philosophy - endless
Calculus - not measurable; no possible derivative
No one can say with certainty if the universe is endless or not, but it most certainly is infinite in terms of math, it's vastness can not possibly be calculated.
