Yeah I think it is what they intended it for. LOL

Boy did that one cause a trip! LOL

Sometimes I wonder if our government doesnt already have a lot of the stuff we are reading about now, but have been using it for years.

I was watching that Air Force One show on the History channel, and they referred to some of the weaponry on the air force one jet as top secret. They also talked about the snipers that follow the pres and his jet for protection to each country, and said they also have technology that was top secret. I was wondering what technology could snipers use that would be top secret? hmmmm interesting.....like maybe scopes that could see through walls, or maybe see brain functions, or scopes that can see and hear through walls.

It is an interesting program. Never knew there were hundreds of people flying out weeks in advance into these countries to prepare for a US presidential visit.

hmmm i missed that one will have to keep my eye out for it sounds interesting, yeah the govt has many secrets, would love to sit in the top secret room and read read read

Wormholes. I think they're way cool and speak to time travel as being possible. But that's fitted in to string theory, isn't it?

i listened to a guy on NPR talk about building a time machine and wanting to go back to see his dad who died.

There's a thing called a paradox, time travel creates that implicitly--see the Harry Potter you can't be in two places at one time and don't let yourself see yourself thing. So if you did create a time machine, you couldn't create a paradox.

But he said he couldn't go back to see his dad. My question is why? Why couldn't you go back?

I mean seriously, if time travel is not just a theory and is a product of natural law, it IS possible and we just don't know how to do it yet, then the idea that if you went past the time/date you created the time machine would mean that it wouldn't cease to exist at the very moment you crossed that creation time/date. You'd be able to go past.

So what that means is that if I invented the machine today, I could still go back to 3 tuesdays ago if I wanted. I wouldn't have to wait for 3 tuesdays from now and go back to the day the machine was invented.

Then again, if time travel's possible, couldn't you, in theory, cease to exist if you go past the time of your birth? Or would that create a paradox of incredible proportions if you actually went back prior to your birth.

Anti-matter's way cool stuff. I think, just like nano-technology, it has interesting applications if we learn to use it.

Nano-technology's always intrigued me.

Also I love how you slow down time the further away from Earth's gravity you get. It would be fun to measure if that holds true and how FAST you slow it down if you go to a planet with a stronger gravitational pull. Does the amount of gravity make a difference on how fast time slows down or no?

did anyone saw that show on ancient flying machines that came out a couple of years ago? I can't remember if it was the History Channel or Discovery Channel. They actually recreated some of those artifacts they found from the Eskimos and the Egytians and South America and they flew...flawlessly...

here is a website on those ancient machines:

ole hooved beaky one,

more cool questions you've raised...I am not smart enough to answer those but for my own theory and big mouth...

I think String Theory would make time travel very possible. But everything becomes an alternative...

if that guy was able to go back to see his dad, and let's say he got into a fight the first time, and this time, he decides to be nice. Then, would there be a change of events? Would he then want to go back to see his dad TODAY?

I am reading this book now by Fred Allan Wolf. He raised a good question:

"Did the early universe have a radius? How could it even have one? Because according to quantum picture it wouldn't have had any radius until that radius was measured? who measured it? When was that measurement accomplished? And then, a few physicists have come to a startling conclusion.

It is OUR observations NOW that are determining the past.

he then states that an observation of an event now somehow sends a message backward in time and "causes" events in the past. If this is true, then what is really the past?

It would seem that there is no absolute past, because there is always the possibility at anytime that some present event will alter it."

it continues to state: "A way out of this paradox is found in the parallel universe theory.

In other words, there are parallel pasts---an infinite number of them. The past that is altered by the present is just one of the many.

Since, according to relativity, there is no such thing as absolute present (NOW, LOL) then waht is present for someone could be the past of the future for another. Consequently, it would seem that the future also communicates with the present, but which future?"

OK, while I understand this in concept...does someone want to volunteer and explain what it REALLY means?? LOLOLOL

I have a question about those airplane models.

It looks like an airplane.

So if they found the model, THEN WHERE IS THE ACTUAL FLYING MACHINE THAT THE MODEL REPRESENTS??

I mean, holy cow, something as big as a flying machine?? well, where could they possibly hide that?

It has to be somewhere.

And I'm sure you have read and seen those GIGANTIC drawings that can only be seen from the sky.

I tell you. WE HAVE BEEN VISITED.

I'm a big believer in that.

I also believe in the Butterfly Effect (and this has nothing to do with the movie).

I do think that when you change something in the past (theroretically I mean, since we can't go back (at least not yet).

But if you change something in the past, you never know what kind of an effect that might have on present day.

Life's a circle. Always changing.

Basically, we're buying into concepts. I guess the question is whether our concepts shape the correctness of what we perceive as true. Are there universal truths such as mathematical concepts or have we created the concept that these things are true, proven, and play out universally? Just because we've "verified" some of these things and they have thus far proved correct does not mean that they will hold true throughout the several universes.

For example, we buy into the idea that a piece of paper that we call a "dollar" has value. That it is intrinsically worth something. But the "value" of money is a concept. We place a value on it artificially. It works because we all buy into that concept. It is the same whether our "dollar" is a shell or a coin or a lovely sparkling gem. The concept of "beauty is in the eye of the beholder."

Or our observations now are explaining the past in a way that's understandable to us based on our perceived reality of "now."

Does this explain how we "discover" new things? Theories? Artifacts?

In theory, we can travel between those parallel universes via wormholes--ok, traversable wormholes. But you have to buy into the idea that they operate simultaneously so that you arrive at the same instant in time as the one you left. That might make the statement above true.

Wormhole: http://en.wikipedia.org/wiki/Wormhole

It would seem that to alter things, you would have to not only create a wormhole that allowed you to travel between parallel universes but back in time too. I don't know the math, trust me you don't want me adding 1 + 1 without a calculator or fingers, and probably wouldn't be able to do it if you taught me it. But theory is one thing that I can grasp, even vaguely the mathematical concepts too, when explained as Hawking does.

Time is fluid, in other words.

It would seem to me that the answer would have to be "all of them." If there is never an absolute present, then the present that is also the past of the future for someone else (or you in a parallel universe?) would mean that it would be possible that the future could communicate with the present because it WOULD be the past of the future for someone and thus already experienced. This way the past would always be informing the present and the present would always be informing the future which would be the now for someone else currently--in that parallel universe. So if communication between parallel universes is possible, it would be probable that we could experience the future--and the past--simultaneously or at least at different instants consecutively.

Did I lose you yet? I'm not sure I'm understanding what I wrote, but I think it makes sense if you parse it out. But I'm open, very open, to being disproved since theoretically I already have been.

Similar to what some scientists argue about windmill power and possible overuse of the clean energy.....

I LOVE THIS ONE!!!

When a tree falls in a forest, how do you know it makes a sound?? (If there's no one to hear it??)

it is a good question, I have answered both yes and no in my life, no because to hear we need to be there and yes because, sound is a vibration in the atmosphere around us,

so even with out an ear to translate the vibration, aka, the sound. the tree still disrupts the atmosphere around said object and sends out vibrations, there just isn't an ear to translate the vibrations into an audible sound,

i tend to lean on the second answer yes it makes a sound,

another thought these vibrations that are produce, when a tree falls, scare off birds and small critters and deer

wee wee....


wee wee!! (and for some reason, I have an image of all those creatures running out of the woods and toward moi...LOLOLOL)

great profound thoughts, Frank...

Gaz, those are good answers! I'll have to come back to it, I got phillo-doughed in the other thread and my brain is mush like oatmeal..

Mel, you've got good perspectives IMHO...
