  1. I would have to vote probably not on that one, but I would be amazed to find out we are wrong. If you postulate a civilization a 1000 years in advance of us or 10,000 or 100,000 or 1,000,000 years in advance of us it would be foolish to try and say what they could and could not do.
  2. There were animals on Xena, Warrior princess? That's a very simplistic and disingenuous conclusion, There are plenty of UFO reports that do not consist of lights in the sky at night. many of them are quite detailed by people whose testimony could put you in the electric chair and are inexplicable to say the least. There doesn't have to be FTL for their to be aliens here, with slower than light technology not much more advanced than what we already have we could occupy the entire Galaxy in a few hundred thousand years. When you are talking about technology hundreds or even hundreds of thousands of years more advanced than ours it's a fools errand to predict what they could or could not do. On the other hand I have to agree, humans did not need nor did they have any help from aliens, gods, or anyone else. They used their own native intelligence, trial and error and their own powers of observation and cooperation to accomplish these things, no alien intelligence required!
  3. Damn, I sit here wondering how to pay my rent and these guys are selling universes. I knew being honest would be a bummer eventually.
  4. What do you mean by this? No one was suggesting dedicated marine fish can live in freshwater or that dedicated freshwater fish can live in the ocean. All surface water on the earth contains some salts, some more than others and fish can and do live in waters of varying salinity. Freshwater fish are probably more tolerant than marine fish to variations in salt content. Sodium hydroxide is a powerful base, high pH is usually not well tolerated by freshwater fish, fish exposed to a high pH would be vulnerable to a rise in ammonia at the very least. The key here is to lower the pH slowly, most fish cannot tolerate a rapid change in pH. Salt is not the issue, pH is the issue. Combining HCl with NaOH will not result in a large amount of salt, if that much of either chemical was present the fish would be long dead.
  5. What he means is that a pH swing is far more dangerous than a slight increase in salt content. When I collect fish i often add salt to the collection buckets to protect teh fish from injury even though the fish are coming from soft acidic water. If I added an alkaline substance to the water it would be more likely to kill the fish. At the very least ammonia is far more poisonous at high pH than it is at low pH. pH is more important to fish than dissolved solid content.
  6. what color eyes is it possible for a human to have? I've seen blue, green, gray, (mine are blue/gray) and brown. Anything I've left out for people other than shades of the ones I listed? I've seen people who had the whites of their eyes tattooed a blue color.

    Triple-helix DNA?

    Is triploidy what you guys are talking about? Most normal cells/organisms are dipliod. but triploidy does occur.
  8. Hang on to that dream astrogirl, I had when I was young but it was too soon but you could very well be in the right place at the right time if you really want it.

  9. Oh now are you are going to say you can make love more than one time a night, braggart! Sex lasting for a few seconds, everyone knows it's just a half second or so I have long suspected the idea of Homosexuality or Heterosexuality as opposed to simply sexuality is a human construct that is meaningless everywhere but with humans. I would guess that in a totally natural state human sexuality comes much closer to what we see in Benobo chimps than what we see in Geese or even gorillas. In Benobo chimps even the children are included in sex play, I would guess that human desire to limit and or control sex play is part of the desire to control others. Controlling others by limiting pleasurable behavior would seem to be the first step in consolidating power. Limiting sex to those people who have agreed to allow others to control their behavior would seem to be a powerful way to influence the group and the social evolution of that group. Power and control takes many forms but control of sex would seem to be pretty basic.
  10. Mine has, when I was young it was 160 now it's 145 by the time I'm 100 years old I'll be a complete moron so I had better get my thinking in now before it's too late
  11. There is probably more knowledge gained in the pseudoscience section than any other. when you correct someone thinking about something they were sure was true it can lead to a better way of thinking. And it's fun to debunk BS too....
  12. An sound pick up, phonograph needle, or microphone turns sound into fluctuating electricity, this is turned into a fluctuating magnetic field. This fluctuating magnetic field makes patterns of magnetism in the iron impregnated tape. When the tape is replayed a magnetic field picks up these fluctuations and converts them back into sound.
  13. You are the one who needs some insight, see this thread if you really want to discuss this. http://www.scienceforums.net/forum/showthread.php?p=449541#post449541
  14. All I have to say is hooray for sex! I also find it odd that the religions of the God of Abraham, Judaism, Islam, and Christianity, condemn sex out side of marriage or even for any reason other than procreation. It almost seems like God doesn't want anyone to have sex for any reason other than procreation and especially sex other than good old fashioned "man on top get it over with quick!" So sad, how much more popular would religion be if if Sunday go to meeting meant an orgy of pleasure!
  15. January 23 of 2009 I will celebrate the 37th anniversary of my 17th birthday. ROCK ON!
  16. Issac Newton and the apple is a popular tale, neither Newton or Einstien had anything to do with likely or unlikely, they worked out the theory's themselves using math, education and intellegence. They weren't just some guys who happened to be in the right place at the right time.
  17. Oh yeah? When and where were these bacteria found on mars?
  18. Anything might be possible, it's just that somethings are more likely than others. I suggest you google Faster than light travel and see what pops up, the things you mention are bits and peices of several unlikely posibilities. http://en.wikipedia.org/wiki/Heim_theory http://en.wikipedia.org/wiki/Alcubierre_drive
  19. Wow, way to cut us to the quick dude, Science isn't able to explain the origin of the universe at this time but there are people working on theories that do indeed explain where it came from and where it is going. Just because science cannot currently explain something doesn't mean it's a miracle. Gravity isn't very well explained but you don't shout miracle every time you fall down do you? Science doesn't make claims that it cannot back up with some kind of evidence. If there is no real evidence to explain something then it remains simply unexplained not miraculous. Science is a work in progress, it will always be a work in progress, that is why science doesn't do miracles, they simply look for evidence. Science has never said it has all the answers now, just that is working on them. The new LHC will be looking into at least part of the problem of where the universe came from. Brane theory also has a few things to say about it but until real evidence shows up science will not make claims about things it has no evidence for.
  20. Actually the main problem would be that water cannot be a liquid at the atmospheric pressure of Mars. It sublimes like frozen CO2 does on the earth.
  21. I'll take that bet, I'd be amazed if there is no life on Mars, deep under ground their is almost certainly bacteria. Bacteria are found in the earth miles deep in places and under conditions that make Mars look like Paradise. Deep with in Mars there similar if not identical conditions. The real question is will we live long enough to collect on the bet one way or another?
  22. Size and mass are not interchangeable. It is possible for a object the size of an apple to be more massive than the mountain. It's my understanding that the mass increase is quite real. The object does have the extra mass, it come from the energy you put into accelerating the object to near light speed. The only visual effect would be the object or space craft being shortened along the axis of acceleration.
  23. Ok you are correct, from the stand point of human time frames the mantle is not molten. It is like a very dense putty or hot plastic but in the time frame of geology it does indeed act as though it were molten and the continents do float on top of the denser mantel.
  24. No problem, at one time all the land area of the earth was on Continent. A hot spot formed under this land mass caused by eh insulating properties of this land mass. all the animals at this time could walk anywhere (in theory) and mix with each other. As the hot spot spread the continents apart these animals lost contact with each other but still show signs of being related. Also land bridges do occasionally come up to connect continents, like central America connecting north and south America and the land bride that existed from Siberia to North America at one time. The is no reason what so ever to propose an expanding earth to explain animals all around the world being related. There is one thing that I can also address and that is the world wide ridge where the earth's crust spreads apart. On the coast of the Atlantic the continents are being spread away from the ridge at the center of the Atlantic. on the west coast the crust that was formed in the middle of the Pacific is being subducted under the north and south American plates. The Rocky Mountains and the Andes Mountains are evidence of this. As this oceanic crust is subducted some of the continental crust is folded up and the subducted Pacific ocean crust also comes up through active volcanoes. Eventually either the Pacific plate will reverse the motion of the north and south American plates or those plates will be pushed into Asia. The plates move because what we see as solid rock actually acts more like very stiff putty over the eons of times these plates need to move around. A good place to see this effect on a solid surface is arctic pack ice, this ice while solid to the touch acts like a thick putty over large areas in real time. This particular movement of the plates from all jammed up into one Continent into several is the second or maybe even third time this has happened. the one before Pangaea was called Gondwanaland. It preceded the current land mass by more than 300 million years or so. Your little picture is cute but it doesn't even come close to describing reality. The continents are more like Ice floating in the ocean. Most of the continent is below with just a small amount of the lighter continental crust showing. Like an ice berg the continents are much thicker in the middle than they are at the edges. The continents are light rocks floating in an ocean of denser rock. the Earths crust is very thin compared to the molten mantle the continents float on. As the crust spreads and is subducted the lighter parts of the molten mantle that come up and spread from the mid ocean ridges are separated out as they are subducted. So in a very real way the Continental crust is getting larger and the oceanic crust is not really going any where any more than a rotating belt is going any where even though it's surface moves. the continental crust is moving on the belts of mantle material , they move and run into each other and get bigger as they collect lighter rocks from the mantle. At one time almost all if not all of the earth was covered by ocean but the process of lighter rock coming to the surface of the heavier mantle has slowly produced continents. Over the last 4.5 billion years the continents have grown. No expanding Earth, just a moving active dynamic crust floating on a sea of molten mantle.
  25. Thanks, i wasn't aware of rolling in those contexts. I knew about the snake that supposedly turns it's self into a hoop and rolls but that is just a myth with no truth to it.
