So which branch of the Federal Government do you work for?
DoD... im being serious too lol

That's what I'm getting at. Photons are massless and thus MUST travel at the speed of light, while Earth has mass and CANNOT travel at the speed of light (thank Einstien and special relativity math for that). If the assumption here is that they all started at the same point, how did we creatures of mass catch up with those speedy photons?
Well its more like: the Galaxies aren't moving, but the fabric of space-time is stretching outward, ...take a balloon and blow it up just a little. Then add random dots on the surface of the balloon, which represent the galaxies. Then start blowing the balloon up. The surface represents the expansion of the universe. As you will note that the galaxies appear to be moving away from each other as you increase the surface area of the balloon. Simple, yes?
Well its more like: the Galaxies aren't moving, but the fabric of space-time is stretching outward, which creates more space-time between the galaxies. For example lets create a 2-dimensional metaphor of the multi-dimensional universe; take a balloon and blow it up just a little. Then add random dots on the surface of the balloon, which represent the galaxies. Then start blowing the balloon up. The surface represents the expansion of the universe. As you will note that the galaxies appear to be moving away from each other as you increase the surface area of the balloon. Simple, yes?
Edit: So the balloon represents a 2-dimensional surface closed back on itself. So in thoery if you took off into space from the north pole in a straight line outward you would eventually come back to the south pole.![]()
Well, the dots on your balloon are actually moving away from each other, and they are moving in space as well. Take a string and measure the distance between two dots when the balloon is partially inflated. blow it up and measure again. they have moved apart.
Another previous job I had. Independent security consultant for museums. Designing access control, cctv, and alarm systems for museums around the country. Tons of fun, boss was a bit difficult, to be nice about it.
But what's outside the balloon?![]()
United States Marine. Don't really think i need to explain much more than that.
But what's outside the balloon?Yes, I see. But I don't like it one bit. Reminds me of a book I read a long time ago called Flatlands. The travels of a 3-dimensional creature in a 2 dimensional world, and the new perspective it gives, and the difficulty for the 3D guy to explain to the 2D creatures what a third dimension would look like.
Anyway, this stuff is not intuitive, but I guess it's the only way to make the math of the universe work. I'm going to rinse it out of my brain tonight with beer (I listen to a podcast all the time called Startalk, Neil deGrasse Tyson, so I can't escape it for long).
It's important to have a job that makes a difference, boys. That's why I manually masturbate caged animals for artificial insemination.

Nice to see at least one other person involved in animal husbandry.![]()
I'm a farrier.
I clean, knife, and trim horses feet to balance their movement. Heat either a premade shoe, or straight stock, and shape it to fit the trimmed foot. Then (after cooling) I nail it on, set clinches, and make it purty for the client. I know as much, (sometimes more) about the distal equine limb as the vets do. I am able to speak to the vets in doctor-ese, as well as simplifying things for the non-medically trained clients so they can understand the three page printout that the vet gave them.
The secret process doesn't make your cheap shampoo/conditioner/bodywash/lotion/2n1/3n1 any better. Their trade secret is in the design of what is essentially an inline blending system. It just makes it so they can mix it faster and thus cheaper.
Typically the blending process is done in large purpose built blending tanks. It takes a few hours to mix a batch. Plus the floor space of a mixing tank, plus the cost to purchase the mixing tank. The entire blending system they have is about the size of a large desk. The actual mixing area is about the size of an apple. Pretty nifty. Wish I could tell you more.

This is one request I received today: "I'm trying to plug speakers into my computer. I see a plug for headphones and microphone but not speakers. "
A dying breed that luckily can never completely disappear completely.
Another important difference (and this goes back to the inadequacy of any analogy) is that the closed 2D balloon surface is embedded within a 3D Universe, whereas a finite 3D Universe doesn't need a 4th (spatial) dimension to bend in to close back on itself.
