Red shift?

According to a show I just watched the atoms that makes up the visible universe actually consists of only about 5% of the universe. Dark matter makes up about 23% of the universe, and the remaining 72% is made up of dark energy. Dark matter apparently is what made galaxy development possible, whereas dark energy is responsible for the inflation that is expanding the universe at ever quicker speeds.

Somewhere else I once heard these same things, but on top of all that they said that because the universe is expanding at faster and faster rates, eventually it will reach the point where other galaxies are so far away that light from them can never reach us because the rate of expansion is actually faster than the speed of light.

In the show it talked about two galaxies colliding and how the visible matter reacted in a predictable way given physics as we know it, but that the dark matter, which they likened to scaffolding around visible matter several times through out the show, continued on moving in a straight line as though nothing had happened.

Now here is my problem. From several sources I hear that the universe is expanding, and that it causes all other galaxies to be moving away from our own, and yet its possible for these other two galaxies to collide and for scientist to study them? An analogy they used a few times for the expansion of the universe was dots on the surface of a balloon getting farther apart as you blow air into the balloon. If that is true how do galaxies collide? Why aren't they constantly moving away from each other?

I'm not an astrophysicist. I don't really understand any of this stuff. I was once really interested in all of this stuff but as much as I like math, I don't enjoy it that much. If dark matter is what is helping keep matter together, and dark energy is what is pushing everything apart, and there is so much more dark energy than everything else, how are we still together? It seems to me that every time a scientist gets an answer to a question then suddenly just have a dozen new questions to answer based on what they just learned to answer the last question.

Hack the planet

I've had so many things lately that I've wanted to put on here but I was never at a computer at the time. Now I can only remember one of them and that's the one I haven't done any work yet to accomplish. I watched a show about code breakers and different ways in which people over the years have tried to hide their secret messages and how they were eventually cracked. Now I want to invent my own "unbreakable" cipher and put a message on here as a challenge to everyone to try to crack it.

Any code invented by someone can be cracked by someone else eventually. Just look at how many times lately in the news there has been a story about a group of hackers breaking into another company's system and crashing it and stuff like that. Now I don't condone what those groups have done, but it is a perfect example of how some one's "secure" code can be cracked by someone else. Everyone of those company's had computer security systems of some kind I'm sure.

One of my favorite movies of the 90's was Hackers. And as grossly unrealistic as some of that movie was it did point out something. There are some groups of very smart people out there on the Internet that it is unwise to mess with. And if you do poke the sleeping bear prepare to have very expensive paper weights because your computer will soon be garbage.

Anyway all I really wanted to say is I hope to have some updated posts soon. The decoding challenge, and anything else I might remember I wanted to put on here.

Where evil comes from.

I've been doing some research into the long standing philosophical debate about evil and why it exists and where it comes from. And I was going to come on here and write up a long post about my views on evil and attempt to use all sorts of logic and common sense to make my points. Then I realized something. The majority of the world's population, or at least the people I deal with on a daily basis, have no logic or common sense. I believe that's where evil comes from if it does in fact exist. If everyone had logic and common sense I would think it would tell everyone that living peacefully with everyone else would be preferable to living in fear of being attacked by aggressors. So therefore if no one were the aggressors most, if not all, man made evil would cease to be.

Sadly, while it is possible to teach logic, most people seem unwilling to learn it, preferring to live passionately and let their emotions rule their actions. And while it may be possible to teach logic to those willing to learn, common sense is something that can't really be taught.

Light at the end of the tunnel.

Well about a week ago a stomach virus got me. I spent about 30 hours feeling very nauseous and exhausted, along with about 48 hours of fever. The worst part was it hit me when I was about to go to sleep after a day of work. During the whole illness I got never quite get more than a series of naps that didn't make me feel any more rested.

Why do I tell you about this? Well because there was one very interesting experience through it. That totally exhausted but unable to get restive sleep state I was in meant my dreams and reality blended in odd ways. Firstly let me say I had been playing Fallout 3 in the days before my illness struck and for some unknown reason I started to think about the movie City of Ember. Now both these things involve escaping from an underground settlement. So my exhausted, feverish mind really dug itself into this idea of being trapped in an underground settlement.

I can't tell you the overall story my mind constructed in these dreams, but even as I was crawling in and out of bed for whatever reason, I just couldn't stop thinking about. I'm not sure what exactly I thought of it, or if I truly knew the difference between my dreams and reality at that point even though when I was awake I was aware I wasn't underground. It made for an interesting day until my stomach settled enough to be able to get some true restful sleep. All I can remember for sure was there were different factions fighting for control of the settlement, and for light. There was a big squabble over lighting the main cavern.

The other odd thing was the name Sesshomaru. The name kept popping up but I can't say for certain I ever stumbled across this character in the story, or who's side he was on. The whole time I was aware the name came from an anime show I'd seen in the past. At the time I thought it was a character in the show Rurouni Kenshin but in trying to get the spelling right just now I came to find out it was actually from the show InuYasha. That would certainly explain my difficulty in trying to figure out exactly which character from Kenshin he was. Being has it has been years since I've seen any anime, let alone those particular shows I'm confused as to why my brain dug up that name to throw into my dreams.

One more oddity of being sick that first day. Water tasted horrible. I knew I had a fever, about 100 degrees at that point, and being sick had purged me of a lot of the water in my system, so I knew I had to drink plenty of water even though it tasted bad. The simple joy when I finally woke up feeling better and that glass of cold water actually tasted good again. It is very hard to stay hydrated when water tastes bad, but I managed. Plus now I know I really can survive not eating for a day. Hell, even that second day I barely ate anything.

Anyway I spent a couple of days sick, and that led into a long holiday weekend for me to recover. Yesterday when I drove to the grocery store everything seemed just a bit off. It was so odd to be leaving my apartment after so many days shut up inside. I came out of all this with a bit of a cough and sometimes it seems like my body hasn't figured out just yet how to completely regulate my body temperature.
