Why hasn't NASA sent a space probe into one of these alternate universes? Would the space craft send us info.?

IF there are alternate universes, we dont know about them, and we cannot communicate between them, much less send probes into them.

do you really think they dont have telescopes? if they have the tech to transverse solar systems then dont you think they can devise a device to look at us from afar? after seeing what a warring species we are it seems theyd rather study us from afar. we're dangerous.

I grew up just north of there. And I suspect the reason why few people are knowledgeable of UFOs is the obvious one. There aren't any. At least in the sense of alien or secret government spacecraft or triangular black blimps or whatever is in vogue today.\n\nWhile I would love for there to be aliens cavorting around the planet (I used to be an astrophysicist) it is often embarrassingly obvious that various UFO sightings are less than they appear.\n\nBasically, the best verified sightings are of lights (which could come from a number of obvious and not so obvious phenomena), and the most detailed sightings (aliens, probes and that whole bit) are the least verified.\n\nIt is also very suspicious that the nature of UFO reports has evolved to match our current level of technology. A century ago it was myster blimps and night flights of spindly aircraft, then it turned into flying saucers.\n\nThe big "incidents" have been reviewed numerous times and are clearly not anything out of the ordinary. Roswell for example *was* a coverup - of secret military high altitude balloons intended to detect Soviet atomic bombs, Project Mogul. This has been known for years now, but Roswell still pops up on TV along with Area 51 as the secret storehouse of alien spaceships or whatnot.\n\nThen there is stuff which pops up that says the B2 stealth bomber is using alien antigravity technology or something, which is all very silly. There is a well known (and public) trail for the technology of stealth (the nitty gritty details are secret, but the principles are well known) and the flying wing design.\n\nBasically one has to conclude that a government that couldn't pull off a simple burglary or hide its secret prisions and info-tapping more recently, can keep all this alleged alien stuff under wraps for 50+ years. That seems the hardest bit the swallow.\n\nKarl Pflock wrote a book about Roswell, now unfortunately out of print, which is excellent. He started as a beliver and ended up convinced that it was all due to Project Mogul.\nsee: http://www.amazon.com/gp/product/B0006PBXB4/sr=1-5/qid=1137560494/ref=sr_1_5/102-4624807-3864156?%5Fencoding=UTF8

No - (let me guess all you people who think we did will give me a thumbs down !!!!)\n\n- My old pocket calculator has more power than the computers used 'to get to the moon'\n- photographic evidence\n- the camrea evidence\n- if they got there, why did they then just 'stop'\nand not sent many other missions there / set up a research station etc\n\nI do, however, think that they DID get there years later - after all what would happen if a space craft passed over and there was no moom buggy, footprints & flag.\n\nIQ ? HAH !!!! IQ does not measure important things like common sense, creative thinking, social skills etc etc\n(and YES I do know mine - its above average I just choose to dismiss it)

Might be better to be more specific and tell us the question.  It is hard to just give you information on space - seeing as it is infinite for starters.

There is no evidence that alien species from other worlds or other galaxies have ever visited Earth. The examples given have all been debunked by numerous scientists. We'd like to believe there is life out there, but we haven't heard from anyone yet. Because the distances are vast -- measured in hundreds of thousands of light years -- it is more likely that we would have radio or television transmission, which travels at the speed of light, than a visit in person. Maybe they're listening to our TV broadcasts and don't think we're intelligent enough to contact.

We don't know yet, however, I pretty much believe that there are aliens out there.\n\nThere are at least 7*10^22 or 70000000000000000000000 stars out there and it wouldn't make sense that only one of them provide a hostile planet.\n\nThere have been some evidence:\n\n1. Unexplained UFOs\n2. UFOs sightings on the Moon\n3. Pyramids and faces of humans on Mars.\n\nThis not only tell us that there are most likely aliens, but that they're not only visiting Earth, but the Moon and Mars too have been visited by aliens.  My guess is that they receive our signal and is much more advance than we are, so they visit our Solar System and found that the signal came near the inner planet section, and then they came across the Moon and the Earth.  They studied about humans and went on Mars to try to find Martians as well as to tell the Martian that there's people on Earth.  However, they didn't find any aliens on Mars.\n\nAlso it is calculated to be 1 billion planets with life on them in this universe.

Which one? There have been at least 4 but the latest one is still looking for signs of life.  check out http://wwww.nasa.gov

The probability of life on other planets (or moons) is certainly given. Just the other day a spacecraft found liquid water and volcanic activity on Saturn's moon Enceladus. So it's quite possible there could be life, in a primitive form at least, as near as Saturn's environment.\nAs to other galaxies, we'll never know. It's too far away - we're talking millions and billions of light-years. So even if there was life in other galaxies, the information to reach us would take millions and billions of years.\nGoing there is out of the question. Mass can't even reach the speed of light, meaning that to go to the nearest star, Alpha Centauri (four light-years away), would take very long. With a Space Shuttle, you can go at 28000 kph (17,500 mph). Light travels at 300000 kilometres per second (186,000 miles per second)! This equals 1080000000 kph (675,000,000 mph).\nSo given today's technology it would take slightly more than  150,000 years only to reach Alpha Centauri.\nBetter make sure to have a good book on board with you.

There might be intelligent life on other distant planet, but not in the White House.....

I think you were watching a sci-fi show, maybe artist's conceptions of planets in other systems. We can confirm that the other planets exist by watching for gravitational anomolies but our tech isn't up to the task.

Okay, we are finding and discovering new forms of life all the time with new technology.  There are new marine animals found with the deeper we are able to explore.  Animals, bacterias, all forms of life are mutating and popping up all over the world.  On mars, they've discovered water on the planet and plant life under the surface of this water.  \nOkay, so it's not Star Trek yet.  We haven't communicated with alien beings...that we know of.  But that's not specifically what you asked now, is it?

if only someone really knew, I think the universe never ends.  I would really hope that we would find new planets outside our own solar system and we would really find other planets like Earth.  I still have time to pay attention and hope they continue to explorer.

There are a lot of people (scientists) working on this. A recent documentary I watched showed how they are trying to prove that alternative universes might exist (I think this started with Einstein). If so, someday they might find out how to move between them, which could be a form of time travel. I believe in the possibility of many things that have not been proven.

I don't know about experiments and alien visits. But I know that I'd like to think that there is more out there some where. I don't even know if there is a chance that other intelegent life exists for not but I can't help but think that other planets in the universe have to be suitable for some form of life and continue to sustain something. We may never find it or know about it, especailly in this life time but there has to be more than just Earth.

we will never know whats going on out there if we dont explore it.\nmaybe there is aliens out there who would want to communicate with us or there may be some asteroid out there that is going to hit the Earth in near future.

I don't know.  But it would seem to be something not of this Earth.  I'd be interested to find out someday though.
