For example, I think their communicators are probably possible.  Phasers are probably possible.  Speech recognizing computers - probably.  But the transporter?  I don't think so.  Traveling at the speed of light or greater - I don't think so.  Artificial gravity?  Warp drive?  Inertia dampeners?\nMeeting beautiful women who are attracted to you on remote planets that speak english?  I don't think so :-) .

Communicators?  We already have walkie-talkies.\n\nPhasers?  Don't know what exactly those are.\n\nSpeech recognition?  Already have some rudimentary stuff.  Don't know how well they work though.\n\nTransporter?  I wish.  No one would ever have to waste time commuting to work.\n\nWarp drive and faster than light travel?  Theoretically possible, but perhaps a practical impossibility.  With a huge energy source (gravity of a black hole?) you could distort space-time such that relativity no longer applies (the warp drive "warps" space-time).  Could a matter-antimatter reactor do it?  I don't know.\n\nArtificial gravity?  Don't know.  Doubt it, other than little centrifugal force tricks (rotating space station).  Manipulating gravity for the warp drive would be hard enough.  Trying to somehow localize its influence to floor plating on a space ship is probably asking too much.\n\nInertial dampeners?  Nothing really fancy about this in theory.  Just need little thrusters that respond super-quickly to undesired accelerations.  There might be other tricks you could try if you've already got that warp drive.\n\nMeeting women from different planets?  I'm not convinced I haven't already.

At the present time, we just don't know.  If you saw pictures of aliens, what you saw were fake.  Nobody on earth has yet to produce a verifiable image, photographic, electronic or hand-drawn, of a living creature that originated elsewhere in the universe than from our home planet.  Nobody.\n\nAlso, at the present time, we suspect that there is no other planet in any nearby solar system that's host to a sentient race of beings like us.  That does not mean that some form of what we call "life" is impossible, but just think: out of the billions of living critters that now inhabit, or did in the past, our home planet, only one of those life forms evolved to the point where it (us) can even begin to think about such questions.  That by itself will tell ya we're sorta unique! ;-)\n\nIt sure would be interesting, wouldn't it?  But imagine if you will what it might be like if those alien creatures we fantasize about were an advanced race of carnivores that look upon us as another breed of cattle, fit only for eating!  Yow!  Or, how about if they were friendly, warm and fuzzy folks who just love to make nice with us - but they carry an infectious disease that there's no cure for.  Oh boy.  Or maybe, like Darth Vader, they just consider us a nusiance worthy of one blast from a super-mega cannon that blows Earth into dust?  Whoa!  Hey dude: you SURE you wanna meet aliens?  \n\nAll this is just idle speculation.  The hard fact is, even if there were creatures just like us somewhere in the universe, we are not gonna know about it, because the distances between them and us are just too great to permit interstellar travel, the hazards of such a trip are insurmountable, and no means of communication can travel fast enough for us to hear from them and be able to answer back.  Kind of a bummer, isn't it?

see acc. to physics theory sound cannot travel in vaccum so space astranauts need to use radio waves in the form of wireless phones to communicate with each other,acc to u they r able to listen to each other without radio waves then there must be some other and developed device through which they can communicate.but without any such i disagree with u, they cannot communicate.u must be having som wrong information. check it out dear

I'd say yes...but then I don't know how to explain it.\n\nThe ability to explain, and therefore duplicate, is based on what we know and the tools we have for exploration.  What I think you're getting at is,  "...is it possible for something to be inexplicable even though we know everything there is to know and have all the tools we need to explore it?"  In other words, might there be phenomena in our frame of being that are simply beyond mankind's grasp to comprehend even with all the knowledge and tools mankind can muster?\n\nWho knows?  It certainly seems that way now; but a thousand years from now, if mankind survives that long, who knows where scientific inquiry will have taken us?  It wasn't that long ago when sending pictures through the air was strictly science fiction; now we have the SciFi channel on TV.\n\nI once read somewhere that someone has said, "If mankind can think of it, it will do it."  There are a lot of things mankind has thought of, but cannot do...up to this point.  Teleportation, for example...but wait, teleportation, using a phenomenon called quantum entanglement, has been done...just recently.  OK, dark matter, no one has seen dark matter...ooops, some Stanford brains just did...only a few weeks ago. [See sources.]\n\nYou get the point...perhaps that someone is right after all...if mankind can think of it, it will (ultimately) do it.

Yes, Since the Star Trek show and The movies like the fly,\nI believe it is very possible that a machine can make people\nDisappear and Reappear. Maybe others will know eventually.

There may be objects (tachyons) that move faster than light, up to perhaps infinite speeds.\nHowever, nothing already slower than light can accelerate to or beyond the speed of light.

Are they talking about black helicopters as well?\n\nOh, to answer your original question, teleportation is the movement of matter from one place to another without it going through the intervening area.  In other words, Star Trek stuff, also known as fiction.\n\nYou might check your sources to make sure they don't spur other BS like this.

Radio signals are probably the only way and that is a slim hope. Most people can comprehend that there are plenty of opportunities for life to evolve elsewhere in our universe(it may even be quite plentiful). What most people don't grasp is the sheer magnitude of the distances between these other worlds. the next closest star is Sirius and travelling at the speed of light it would take 4.3 years to traverse the distance between here and there! Oyher stars are at MUCH greater distances. So I am afraid that the only contact we will ever have with an extra terrestrial race is by radio waves and even that is unlikely.

There is a little research and some guy even wrote a book claiming that teleportation is feasible.  But don't buy your home teleportation machine yet.  As yet the only thing that has been transported is a few laser beams.

The one video shows what looks like something much larger than insects.Until people have had some sort of contact or psychic impression such as Remote Viewing it's too soon to tell.Maybe they are as one person said some type of probe. It could be possible for other civilizations to create organic devices or to mimic them. These might also be some sign of a return of a certain species or about some climactic event that's about to happen here.Yea I think I'll go with probes. Maybe nano probes?

You watched Event Horizon huh? \n\nto travel great distances, in faster than speed of light speeds.. the idea is to warp the space time dimension and create a wormhole that would move you from one side to the other.. things we need to work on.. \n\nTo do list;\n\n- how to create a worm hole?\n- how to bend space-time\n- how to know the point you are going to end up\n\nmy guess.. wont be done in 100 years

Sadly, I've actually heard about this before.  I can't believe how much useless junk I put into my head...I'd say pure fiction.  Its just more likely that he was some bored computer geek trying to get some attention.  Its still unclear whether or not time travel into the past is possible.  Based on current science I'm leaning toward the impossible side.  Oh well, 2036 will be here soon enough.  Then we'll know for sure.   ;)

There is a big difference between predictions that the speed of sound could not be broken and that the speed of light cannot. It was always known that *some* things can go faster than sound. Bullets for example. The question was whether we would have the technology to get people to that speed.\n\nThe speed of light is very different since we haven't seen *anything* go faster than light in a vacuum. Nothing. Ever. Furthermore, the predictions of special relativity have been verified in particle accelerators when the particles are going to within a hundred thousandth of the speed of light.\n\nAs an example, at Fermilab protons are accelerated to energies of 2TeV. This is over 2000 times the rest mass of those protons. To accelerate something the mass of a *gram* to an equivalent speed would take about the energy of the largest hydrogen bomb ever exploded. This amount of energy would be needed for each gram to get to that speed, so multiply it by 75000 for a medium sized human. And that doesn't count the spaceship they would have to travel in!\n\nNow, this is how much energy is needed to get to speed we *know* about. To go faster would require even more. Unfortunately, we have never seen a wormhole of any type. But the predictions are that the energy requirements would be even more prohibitive than what I just described.

I'm definitely waiting for 'Warp speed', the Transporter and the Phaser...yes, in time we'll have these things.\n\nOne example is our Stealth bomber which is similar to a cloaked Romulan Warship.

Right now, we're not even close to faster-than-light (or FTL) travel.  All out traveling has to be done at less than the speed of light, so most stars are farther away than we can get to.  Even at half the speed of light (which is far faster than we can travel) it would take 8 years to reach the nearest star, not counting the Sun.  (Not to mention 8 more years to get home afterward!)  Nothing can move faster than the speed of light, so our best hope is to do just like they do on Star-Trek.  The found a way to bend spacetime to get to distant stars without actually moving through normal space, which had less of a curve.  Nobody has any idea how to do that now, so we just have to keep expanding our understanding of science until we do.  Until then, I think our best bet on meeting intelligent extraterrestrial life is to hope for them to come to us!

It is definitely possible. However, we do not have the technology needed to reach the kind of speeds necessary to allow for travel to other solar systems, stars, etc. Here's something to consider, though. Einsteins Laws of Relativity, while not allowing travel at full light speed, do allow travel almost up to (and just short of) light speed. As you go closer to light speed, the traveler's clock would "slow down" as compared to an observer's clock on a "stationary" object. If you got close enough to light speed, you could travel across the galaxy (100,000 light years wide) in what might seem minutes or hours to you, and about 100,000 years to me. Great, great stuff. To learn more about this concept, google "twins paradox". Or go to http://media.nasaexplores.com/lessons/02-060/9-12_2.pdf and scroll down to page three. This will explain it more fully to you.

Are we alone? Probably not. It would be fairly conceited to think otherwise. What is the 'grand secret' the government doesn't want us to know? I really doubt there is any secret. I don't believe any foreign intelligent life has ever visited the earth. Frankly, if they have the technology to cover the vast distances to visit us, then they would have no interest in doing so. If it was the land they were interested in, then we would not be hear anymore. They probably could anihalate us in the blink of an eye.
