Yes... because man knows about all living creatures on this planet....
Who knows -- maybe there are mastodons living in rock crevices somewhere, and we're too moronic to find them.
Moronic?? That is hardly the fitting word. Intelligence levels have nothing to do with finding a new species. Some factors that influence finding a species are: 1) How well the organism hides 2) Where is actually lives (we dont even know about 10% of all the species living in the water... the bottom of the ocean is still a huge mystery to us) 3) When it is most active 4) IF someone is actually looking out for new species 5) Our own patience in that search...

A better analogy would be intercepting a streaming movie going across your network, waiting a while, and then re-transmitting it. You're not sending the same electrons, but you're sending the same bits.
True.... you don't know for sure if it the same electron or photon being emmitted as the one that was originally fed into the bose-einstein condensate (the very very cold rubidium atoms which is actually a new state of matter), but the energy isn't really lost, it is simply held within the electron cloud (since the condensate is really one "large atom") of the condensate... then released once there is enough energy (which is given to it through the other lazer) to knock that photon out again...
There would most likely have to be some sort of wide radius no fly zone around it, as well as a very invasive search for anyone wanting to ride up.

Invasive search? The only people going up on it would be trained astronouts, engineers, technicians.... all working for the government in some way or another, prescreened, and fully qualified to go up.

The security will be fine for this... the only thing to worry about is someone breaching the nofly zone.
If you're worried about other countries attacking it, forget it. This would more than likely be an international method of transportation, and shared with everybody like the international space station.

Just because someone might catch a ride with a bomb on the elevator doesnt mean they need security posts along those thousands of miles... you stop the problem at it's source...
I'm pretty sure that this space elevator won't available for normal civilians to take joyrides either (at least not for a very long time).... its not the airlines... All they would have to do is secure the ground section... and even more specifically the entrance to the elevator to make sure no unauthorized people get anywhere near it...
but that still keep it from being a pain in the ass to secure an area that is in effect several hundred or thousand miles tall
First off... their plans will only be a little over half of a hundred-thousand miles......second, the diameter will be very small at the ends of the elevator (less than a mile at the earth end... only 100mi at the center) third, Why would we need to defend all of those miles from terrorism??...do the terrorists have spaceships now??

Orientation skills (balance) are far different than guessing where a ball will land... and since they don't follow suit, then obviously we have some really bad athletes in these experiments, or different sections of the brain control them...
Your brain does not have really have all the information it needs (posititon of the object, current velocity of the object, etc) in numeric form to make precise calculations on the fly. It's probably more of something the brain sees, makes an educated guess about, and fine-tunes that guess as it gathers more information about the event it is seeing.
Which is basically taking known positions and time intervals, then formulating a best fit quadratic regression line in our own heads... which is almost guessing, just a lot more accurate... Sure it doesn't know right from the start where it's going, but if you've ever caught a ball flying 60mph (sorry all you metric folk) at your head after turning just in time to see it... guessing isn't accurate enough to do that...

explain how there is a difference in a magnetic field within a current carrying object... ?
there may be outside, but that is just because the magnetic field direction is pointed in opposite directions at opposite sides of the current carrying object.... but that would not produce a force on the object itself...
In order for there to be any type of force that deals with electromagnetics to get a net force that isn't zero, there has to be an outside source of magnetism or current (not just a battery, but current flowing through something for the magnetic field to interact with).
It doesn't rely on a difference in magnetic fields... that would imply that the induced electromagnetic field from the copper wire on top and the aluminum on the bottom have a net force that actually pushes them both in the same direction... which can't happen.
Im somewhat comfused with the findings. They say that this device can reduce the effect of gravity acting upon an object (decrease the weight), but then later in the article, they mention "The Podkletnov effect suggests it may be possible to effectively reduce the mass of the ship..."....so what is the actual effect?
If it looses weight... it could simply be a shield from gravity... and it would not effect mass at all... but how exactly could this change the mass of an object?

What you don't realise is that there is no such thing as a true vacuum... Even the "vacuum" of space has quite a bit of hydrogen and other atoms just floating around (I forget the actual number per cubic unit), but even in the "vacuum", there is matter for this device to feed off of.

What came first, the ice age or the ice from and ice age that caused the ice age?
Ice age events are triggered because the sheet of ice reflects radiant energy from the Sun back into space...
Whaaaaa?
Thats a pretty messed up logical statement you have going there. You're saying that and ice age is caused by an ice age? Going by that logic, once we found a way to get into that ice age, there is no way of stopping it because all the ice keeps reflecting back the solar energy... keeping the earth nice and cool... Say all the ice caps have melted.... then how are you going to have another ice age?...there are much more significant elements to creating an ice age...
In order for there to be an ice age, you have to have some element that changes the normal flow of oceanic currents and possibly even atmospheric jets (which will have a smaller effect, but it could contribute). A large glacier collapsing because of an increase of temperature and stirring things about in the ocean is all you need for currents to shift... or even stop. Even the depth of our seas is a factor in the flow of the currents. Volcanoes as well as large voids on the ocean floor also attribute to the flow of currents, which are responsible for our climate on earth today...
Glaciers collapsing are one way of causing an ice age, but what about getting out of it? After you get into an ice age, they theorise that the lower sea levels will uncover reservoirs of methane and other hydrocarbons that cause greenhouse effects within our atmosphere... that's just one explanation, but we still aren't perfectly sure...
The whole system is very delicate, very theoretical, relies on an enormous number of variables, and is very hard to predict...

Chill out... just because the guy didn't understand completely how exactly they measured the speed of light doesn't mean you have to get on his case. So now we all know that you're some bigshot (well... a bit of a) physicist with a huge ego. You're original statement "As a bit of a physicist I can't help but wonder why you think there's a difficulty with measuring a velocity faster than that of light???" is really really stupid. I mean, it's like a math professor (don't get me wrong, I'm not saying you're anywhere near the intelligence of a math professor) wondering why the hell some 8th grader can't do third derivatives in their head, or find the area under the curve of 1/x [1,infinity) spun around the x-axis to create a cone.
Er...no. You don't need to be a physicist to measure the velocity or understand the concept of a velocity and I strongly suspect the original poster understands these ideas quite well.
Of course you don't need to be a physicist to understand velocity. Sure someone might have a concept of velocity, but it doesn't mean that they know the methods and formulas used in wave motion to calculate the velocity of a particle.
The original poster seems to think that not only is there some speed limit at c but also a limit to your ability to measure speeds greater than c. There's some interesting idea in the guy's head that makes him think this even though no popular (or unpopular) article on science says any such thing. I'd love to know where this idea came from.
And without being a physicist, I too thought that there was a universal speed limit (without getting into relativity)... the speed of light. Usually that's taught in gradeschools and highschools, so I'm guessing that's where "some interesting idea in the guy's head" came from.
