I always thought it would be interesting if alien sightings are actually an evolved human race, time traveling to either fix events or just watch us like we would animals in a zoo. lol imagine.

That woman with the hearing aid is ME!!! *gasp* O_O

If you look closely, you'll notice that she has the EXACT same SATCHEL as i do!!!

Waiting for Monroe to give me a call. Mmm phone sex with Marylin. That's the power of love dumdumdum dumdumdumdodo can you feel it...Time travel gives a lot of people hope.

StevilNYC - you and I have the same theory! Seriously, I saw a show on human evolution. They had an image of an early caveman next to a modern day man. They then progressed the physical changes that have already taken place between the two, took in factors regarding how technological advances can change our physiology and got something remarkably similar to the "little grey man" everyone describes. Add to that the fact that drawings of flying saucers haven't changed since cave paintings. A race so technically advanced they have only had one shape ship for several thousand years?! I don't think so!

That's all assuming these sightings and abductions are real of course!

Yep, I saw a kid at the shelter the other night holding a block up to his ear talking. I imagine he is a traveler from the future who has came back to impart knowledge with us. Seriously, there is no way to tell if the woman is on an actual cell phone or is just holding something in her hand, but there are plenty of people out there that are a few bricks short of a load that talk to themselves in an odd manner. Visit a psychiatric ward. That being said, I don't disregard some type of time travel being impossible, just don't buy it in this case.

She would need cell towers, satellites and a whole host of other technology to make her alleged cell phone work.

Unless she came from a future/alternate time line that doesn't require all that...

In his latest documentary, Hawking explains why he thinks time travel to the past is impossible but to travel to the future is quite possible. However a possibitly is not always easy to accomplish.

BMP!

They had this on 'Coast to Coast AM' earlier in the week. My problem with it is it is not a cell phone, she would not get signal. Not a satellite phone, no satellites. Had to be a communication device to signal the time machine. It could also be a sick joke. Nobody had analyzed the original film.

@yossarian

You are absolutely correct. It is a Hearing Aid. Back then, a type of hearing aid they had was large and blockshaped. It did not connect to you. You just held it up to your ear every time you needed to hear.

You just held it up to your ear every time you needed to travel through time. No deloreans, no phone booths, just a big block thing that you held up to your ear. Weird, I know, but there you have it.

She doesn't need a cell tower or satelites. She's talking to the mothership.

Smart enough to travel through time, yet dumb enough to be exposed as a time-traveler. Really? This is news?

i prefer to travel by the speed of thought anyway

I doubt that it's actual possible.

Wasn't it theorized that you cannot go back in time, but only go forward in time? Because of string theory everything has happened already, we already died our children already lived and died and had kids and so forth.

Time travel IS possible (theoretically) - Stephen Hawkings tried to disprove it because he didn't like the way it messed up his view of the universe, but he couldn't do it no matter how hard he tried! The recursive nature of a temporal bubble would not affect those within the timeline. IF the timeline alters because of a temporal event, those IN the timeline wouldn't notice the change because they're part of it. Imagine time as a stream and we're fish moving in it. Now if an event outside our perception (the stream) altered the course, we woudn't know the difference because we're IN the flow.

Stumblin - I think you're crossing String Theory (the attempt to unify quantum mechanics with general relativity) with Verschränkung ('entanglement' - from the famous 'Schrödinger's cat' experiment) and Tiegmark/Everett's 'Multiverse' Theory.

Light speed isn't the ultimate speed limit. Just ask Mel Brooks, light speed is too slow, which is why we have achieved Ludicrous Speed. "They've gone to plaid..."

You may be right Loganoneil, I love this type of stuff I was glued to "Looking Through The Wormhole" with Morgan Freeman. Shit blew my mind!

I tend to enjoy Dr. Kaku but he often only tells part of the story. Traveling backward in time is likely only possible for subatomic particles. Then there is the issue of causality and traveling into the past runs the possibility of violating it. For that reason it is very improbable that kind of time travel is possible much less achievable.

Here's the real way to time travel

DukeAcureds

@juggy
Subatomic particles can travel through time? But everything is made up of atoms, right? So if all the subatomic particles in your body travelled to 1955 at the same time, your mom would get a crush on you instead of your dad? Is that science?

I am not a big fan of Dr. Kaku, but I have to admit that he is right on this one. If you could go back in time it would be to an alternate reality.

Gabe - 10/29/2010, 5:39 PM
Well in theory time travel would require enormous energy expenditures, ones that would dwarf any level of consumption or output we've probably ever seen. Not to mention you could only travel forward since you have to travel faster than the speed of light in order to achieve such an effect. No such thing as negative speed or acceleration though. Even if someone were to somehow try it, they would probably end up like Ender at the end of Ender's Game (i.e. sped up to the point where he ages slower than everybody else).

loganoneil - 10/31/2010, 2:56 PM
Stumblin - Agreed! I'm totally into dime-store theoretical physics too! 'Into the Wormhole' was ABSOULTELY brilliant!

Intruder - It IS theoretically possible by 'naturally occuring' hyper-warped space-time events (ie. 'black holes'). Theoretical physicist Michio Kaku postulated this both in his book 'Physics of the Impossible: A Scientific Exploration Into the World of Phasers, Force Fields, Teleportation, and Time Travel' and in an episode of his Science Channel series 'Sci Fi Science: Physics of the Impossible'.
