Certain horrors in our history would have been avoided. Religion would be debunked. Do I need to go on?

Or maybe it was to the traveler's advantage to CREATE those horrors and see to it that religion was created?

"Hey, you. What's your name? Jesus? Right on. Here... I need you to do something for me...."

Ohhhh... the possibilities of this conversation are endless.

Don't forget the quantum possibilities. Even if they tried to make Jesus in one time line, who is to say he would become a religious icon in a present one. I think the farther back in time you went you would face a law of diminishing returns as the different possibilities became too endless. So probably any time travel that would affect us would be very recent to our own point in time.

But no matter what happened, how would we know? All we would have is the end result (our present reality) with no grounding reference to what might have been or what was.

Hmm, I wonder if its actually possible to go back into time, or just go into another time line that is at the point where you want to be.

Even if we assumed that a change has been made without our knowledge, can we not assume that because of this, the person(s) who realized this capability might never exist?

Doesnt string theroy say thers 7 or 11 parallel universes.

If they ever invent a time machine, you can be the first to go back and stop the Spanish Inquisition.

Well, the many-worlds interpretation can work for that. I wonder if you could somehow go outside all the worlds and view all the reactions to a certain event you started at a certain time, to see all the effects that would happen.

Hmm... Possible explaination for 9-11/JFK conspiracy theorists? :Q

Is the fact that we have never seen a time traveler from the future proof that time travel never becomes something easy to do? My point is that if it ever was to become easy, then eventually someone would have screwed up or inadvertently revealed themself. Of course there is the whole multiverse idea.

If we could even send subatomic particles that would be very useful. You set up your particle detectors, and your time machine. You can use particles to duplicate a binary string for example to send messages, perhaps for uses such as military intelligence.

For any meaningful trip back, keep in mind that not only would you have to overcome the hurdle of time travel, but you'd also have to be prepared for a very long space flight. The earth is never in the same location twice. It orbits a star which is moving within a galaxy which is moving. About the best you could do is setup your time machine for a very quick trip back, like a couple of seconds. You'd end up on the other side of the planet if you planned it just right.

You could go back 35 yrs. with a tanker truck, fill it @.36 a gallon then sell it now for $2.36
a gallon and make a killing!.....oh wait gas had lead back then, nevermind.

How are you going to pay for it? Your atm card? Cash (bills that were printed later?)

Well, maybe you could find out the old winning numbers of a lottery, then go back in time and buy a lottery ticket. It would sort of defeat the purpose of not altering the past, but who cares, you've got money.

Now, I can't see the video... But all this talk about going back in time can never happen, as you would really need something to come out of in order to travel in time. It's not like you're going to walk into a DOOM-style porthole and poof, you're standing in the middle of a cornfield 500 years ago. You would only be able to travel back to the time that the first fully-operational machine was functioning.

Yeah - maybe around this time period, the population was dwindling, STDs were rampant, shellfish populations were utterly depleted, and people were constantly at war. So, someone went back in time to introduce a religion by way of a series of grandiose stories to offset these problems.
Time traveler does the whole "resurrection" thing using technology to convince the people of the time that he's really divine, and he gives a few rules:
"Be fruitful and multiply, no sex before marriage, shellfish are bad, and love thy neighbor."
And so on.


Something else with time travel that amused me - I read that if anyone wanted to have a time traveler's get-together, there'd only need to be one, and everyone would be able to attend. :D

Invoking such a large occurance might delay the creation of such a traveling device, or, perhaps, stop it from being realized altogether.

Time would be way too sensitive for this ever to be practiced.
Then you may get a fun paradox - if there's no need to build a time machine, then one will never be built, and so no one will go back in time to change the past. In that case, you're back where you started, building a time machine. :)
Or, maybe not - since someone already went back in time, it's already set in history. There is presently no need to build a time machine, but that doesn't matter - the mark made by the time machine's travelling backward has already been made and cannot be erased. Result: there's no paradox, the present is changed, but the new present has no time machines as a result.

This guy, as well as you all, clearly have not seen the television classic "Tiny Toons." If you have, you would recall that Plucky Duck, forgetting to do his homework, decided to build a time machine to go back in time to the day it was assigned so he could have all weekend to complete it.

As soon as he decides to build said time machine, future Plucky appears.

Time travel proved to be far more complex than any of us imagined, however, when Plucky went back to prehistoric times (leaving future Plucky behind to do the homework, mind you) and managed to bring a dinosaur back to the present day. After some wacky antics, the dinosaur was returned and Plucky traveled back to the present day - only to find his future self still goofing around, homework incomplete.

Plucky Duck's adventure is clear evidence that the past cannot be altered, as both our present and future selves are ultimately massive douche bags.

And don't even get me started on the Simpsons.

The idea that someone should go in the past to alter history is damn frightening. Preventing the holocaust and WW2? That would cost at least a billion lives of the people living now (-if- going backwards in time was possible beyond pop science coffee table books of magic).

Time travel is possible for going forward as the clip made mention of. (Relativistic change.) This is a crude one-way street.

However, if it came out that a multiverse theory was true and you could somehow find a means to go to an alternate universe there is no guarantee you could control: the extreme quantities of energy required to make such travel possible, which univerese you end up in, when you end up there, and how similar it is to this one (imagine something like a physical constant being different..you're screwed!).


And LOL I love the reference to Flatland with the paper clip example hahahahahahahahaha oh man too funny!
