time travel

https://www.sciencealert.com/physicist-discovers-paradox-free-time-travel-is-theoretically-possible The paper is here: Reversible dynamics with closed time-like curves and freedom of choice Um. Suuuure. :confused:

Backward time travel carries its own self-defeating paradox. Forget about grandfathers. You must have a machine that travels backward through time while permitting your conscious time stream and all cellular life processes to continue forward, along the downhill slide of increasing entropy...

http://grendz.com/pin/4888/ Here is the paper itself, although it's paywalled. I've not read the paper, and I'm certainly not as qualified as Dr. Tippett, but I remain firmly sceptical. The article casually says that it's possible for this bubble to move faster than light, but wouldn't that...

I have developed some new thinking concerning time travel and Utopia. Honestly, it makes me feel sick thinking about it. So, about five days ago I was watching something about time travel. some new thinking came about.My first thought was " its not possible to time travel ". next I thought "...

I don’t understand why it’s claimed that time dilation would equate to a form of time travel. Time dilation would cause an aging rate differential but that can be achieved without time dilation. A person that ages slower or lives longer than another doesn’t time travel in to the others future...

Here's the hypothetical: You are a healthy American male in your twenties. You have traveled back in time to 1943 in an undetectable way - you fit right in, all your papers are in order, etc. You cannot return to the present or do any further time jumping in any direction. Whatever effect...

Okay! Here’s a thought experiment I dreamed up. Let’s say that you have invented the first time machine (!) - and you decide to go back in time to win last week’s lottery! - having first memorised the winning numbers. Will the winning numbers be the same?? Will the slight effect of you going...

http://andersoninstitute.com/ The above website says not only is time travel possible, but that governments have been secretly using time travel technology and don't want the public to know. This includes events like the Philadelphia experiment and the inventions of Nikola Tesla. This page...

OK, don't make fun of my nice UFO people....but I have question this morning I could use some help with. The part of the question I need help with is ...I would like a good time travel scenario. Like what is physics saying, say with string theory, about the possibility of time travel. Also...

Does the argument "If time travel were ever possible, it would have happened in the future, so we would have come back to visit ourselves already" imply that the future has already happened, therefore our lives are pre planned?

(I'm not sure if this is the right place for this, it seemed the most reasonable choice.) Dolphin Connection International is having a symposium on Dolphins & Teleportation in Kona, Hawaii, next June. It promises: Whatever that means. Speakers include: More details here including speaker bios...

In an effort to eliminate some of the insanity among otherwise intelligent skeptics, I am attempting to inspire more skepticism among my fellow-skeptics regarding outlandish claims made by "theoretical physicists" (a.k.a. fantasy-makers) regarding time travel. I am disturbed to see so many wooed...

Didn't see a thread on this, and the science forum won the coin toss! Here's the video http://www.youtube.com/watch?v=Iv9f-s0KmOU One of the extras on the DVD includes a bit of film which has an old lady walking along, holding something to her ear. A mobile phone? One from today obviously...

http://news.google.com/news/more?pz=1&cf=all&ncl=dYU12oGhS3kChfMP75obngcS9JknM&topic=e I don't see why. You don't have to be a rocket scientist to figure out that your phone won't work too well in 1928.

Was a Time travaller caught on film in a charlie chaplin video? http://technolog.msnbc.msn.com/_news/2010/10/26/5353411-cell-phone-time-traveler-from-1928

Not much to say really. Just watch and be amazed. Y6a4T2tJaSU

Supposedly, in the Terminator movies, the war against the Machines is led by John Connor, who's father came back through time to procreate him in the first place. So basically the future is based on the future already happening. But this is not how time travel works..right? If time travel did...

I was wondering about time travel: I i went back in time and killed Hitler, why would i go back in time in the first place?:confused: If i went back in time to meet Jesus, how would that affect christianity?:confused: If i went back in time with a very advanced computer and gave it to Richard...

(A short essay I wrote some time ago) The biggest problem I can see with travelling in time is a problem easily summed up in one word: inertia. What am I talking about? Well, if we consider time to be an additional dimension in which we can move, then our biggest problem when moving in that...

And, at $10,000,000, it's a bargain! Better hurry, though...there's a time limit to bid on it (no joke): http://cgi.ebay.com/Time-Travel-Theory-Project_W0QQitemZ140192550055QQihZ004QQcategoryZ1310QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

I never thought there could be such a thing as time travel because if there was we would have surely met someone from the past or future, wouldn't we? But what about John Titor, time traveler from 2036? He says we will have a female president and she won't do anything...think Hillary will win...

Imagine being able to travel back in time, say, 5000 years, to an area with human encampments. You don't get to bring anything except your knowledge. What advantage, if any, do you think you might have with relationship to the primitives? All I could come up with was certain comical noises...

This is an offshoot of the what past civilization thread. Assumptions: You're the ultimate fly on the wall. You can go back in time as an observer to any place, anytime. You can't be seen or heard and will not affect anything. You can understand all spoken and written languages. What past...

World Breaking Discoveries The PAST Throughout history encounters with divine beings such as ‘gods, Angels, or God’ have been reported in myths and legends and often subsequently documented in (what are now perceived as) religious texts. The characters in those religious stories or the...

Has anyone heard of this guy? He appeared in a BBC Radio 4 interview this morning (listen here for 7 days) and claims to have a realistic hypothesis for backward (and presumably forward) time travel, or at least time-messaging. He says he got into black holes as a specialism as a "cover" for his...

If I travelled back in time to 1971 and took a cookie out of my neighbours cookie jar, then travelled back to the present day, would the world be a completely different place?

Wow. This nutcase thinks he's travelled through time. Wonder if he's going to be involved in the "project" referenced by Randi in his commentary recently? This is his website: www.ingentrormig.nu As to the phonecam footage; so many holes and discrepancies. To me, the tattoo on the older guy...

I am a time traveller. I came from 195# when I was born and since then have been travelling forward in time at the rate of one year per year.:D I somehow doubt that Randi will contact me for an interview.:D

I was watching a program on the Shroud of Turin on National Geographic the other night. The conclusion was that Leonardo da Vinci was the painter of the piece and presented some compelling evidence. But that's not what I want to to talk about. No, I want to ask you - if you had the ability to...
