Seriously though, spock isn't meant to be that heavy
No one has EVER seen a fat Vulcan outside of Convention centers.
It's just not cricket.


I have nothing Cosmologically sound for you this time.
Next one though, yes.

I really want to believe that "aliens" will make contact sooner or later.
I also don't think they'll be hostile.
Hostility, for having the technology to even visit other planets, well that's just stupid. And a waste of time, effort and energy.

I say this knowing full well that I've depicted these aliens in a fairly dark matter, but there it is.

Interstellar distances are immense.
If I may quote the Hitchhiker's Guide to the Galaxy, "Space is big. Really big. You just wouldn't belive how vastly, hugely, mind-boggingly big it is."
Mr. Adams was exactly right, though a few more adjectives could have been used to get a grander scope of cosmological distances.
To put it in perspective, once you get to a certain point, the vast lengths between the stars must be converted into completely different data units.
There are approximately 150 Kilometers in One Astronomical Unit. [AU]
AU is the distance between Earth and the Sun.
One Light year, which is the distance light travels through the universe in the course of one year, is equal to approximately 63,241 AU.
That itself is approximately 948650000000 Km, or ~9.5 x 10^11 [ten raised to the 11th power] Kilometers.
The closest star in our local neighborhood, Proxima Centauri is just over 4 light years away.
That's ~3.8 x 10^13 Kilometers away from us.

And the closest galaxy, Andromeda, is 2.5 Million Light Years away.
But to go beyond that one must use the Unit of the Parsec, which is roughly equivalent to 3.26 light years.
There's really no way to compare these to any distance on earth, since if you decided to say that a grain of sand was the earth, Proxima Centauri would be off of the surface of the Earth.

Even going at the speed of light, getting to Proxima Centauri would take tens of thousands of years.

So either one of two things needs to happen:
1) the Human Race needs to find a new propulsion system
or
2) we need to take a page from Futurama, and increase the speed of Light.

I ran out of steam on this one.
But I really like doing these so that counts for something I guess.

What now?:
After the Big Bang occured a process known as Inflation took place, wherein the Universe, the fabric of Space-Time itself was expanding.
What is most interesting I suppose, is that this expansion is continuing, and the further out we look, a different galaxies, quazars, whathaveyou, we notice, and calculate that these large celestial objects are accelerating away from us. One might assume that this puts us in the middle of the universe, however Hubris is the better part of imbecility. What we find is that, again using Einstein's Relativity, from another galaxy's point of view, we in the Mily Way are accelerating at impossible speeds.
This doesn't have much to do with the comic however, as it discusses The Cosmic Microwave Background. This is the aftermath of the Big Bang, in that in the first few seconds of the Universe's existence, all of space and time we know it was condensed into an impossbily miniscule point and then expanded at an exponential rate, there was much heat and light, but as the expansion increased the space between those heated particles has become immense, and this Microwave background [it has become redshifted] now registers at just about 2.73 K [Kelvin]. When you see a radio transmission in a television show, or a film where they are using large radio telescopes to look at the sky, the background noise that appear near the bottom of the reciever, or the background noise they hear and talk about is this Cosmic Microwave Background.
And ten percent of the static on your television is said CMB.

Its a bad Pun I know, but it worked, and I'm bored.

Astronomer's are still cringing.

Still though:
The arms of any given Spiral Armed Galaxy are largely made up of localized sections of The Interstellar Medium [ISM] and are therefor dangerous places to wander through.
Despite poplar belief, the Individual Spiral Arms barely move, [though they do move], while star stystems themselves transverse these areas.
There is a theory which states that everytime Earth has passed through a Spiral arm, a Mass Extinction occurs. There isn't much evidence supporting this claim however, so don't get your knickers in a twist.
The Spiral arms are also the Galactic Crucible for Star Formation, all of the ISM is there, and the easiest, O and B type blue and white stars are created there, this is the reason that when you see a picture of a galaxy, the light is largely in the blue spectrum.

I found this through a buddy of mine...
I don't know what Im doing, but at least its fun.

Astronomers everywhere are cringing.

But in all seriousness:
Black Holes are few and far between in the universe though we do know that they exist.
One of the major issues however is that we cannot see them, as their name implies that they are "black." In other words, they give off no light, so to find them, astronomers must search for large [or small] accretion disks from nearby stars being pulled into the individual Black Hole's Singularity.
As far as modern scientists can postulate, past a certain point nearing the event horizon of a Black Hole, Kepler's Laws of planetary motion no longer apply and are instead replaced by Albert Einstein's famous general Relativity theorem.
For example, based on the fram of reference, for two people, one entering the singularity and one observing, the Entree will experience what is known as Time Dilation, in which, though their time remains a constant, all that they see when they look back from the area between them and the Event Horizon, will begin to speed up. Where as the Observer will see the Entree's time slowing.
When, to the Observer, the Entree crosses the Event Horizon, that person will be perpetually "caught" in a state on non-motion. Time will have stopped completely for them, whereas the Entree will have been long gone, pulled into the Singularity by its immense gravitaional field.
