Time travel is not possible right?

[My Hubby Loves Civ]

I love archaeology and discoveries of our ancient past. I find it fascinating how much can be discerned from simple bones and teeth. Truly, though the following reconstruction seems a wee bit odd......

Nilsson puts the finishing touches on the reconstructed face of the ‘Stonehenge Man'. Explains Nilsson about the subject: "The grave was discovered in the late 19th century but the bones were recently the subject of extensive analysis and surveys. Some of the results from those analyses are amazing: He was born around 5,500 years ago well to the west or north west of the Stonehenge area, probably in what is today Wales, Devon or Brittany. At 2 years old he moved to the area near Stonehenge, and aged 9 he moved back to the west again. As he grew older his frequency of travel back and forth between those two places increased. How do we know all this? By analyzing the successive layers of the enamel in his teeth, isotopic values of strontium and oxygen reflected the sources of his drinking water.
He lived some time before the famous stone circle was built, but decades after his death, the mound of his grave was massively enlarged, one of the grandest known from Neolithic Britain. We also know from the analysis that he had a much higher percentage of meat and dairy products in his diet than would probably have been normal at the time. And he was taller than the average Neolithic man—172 cm compared to the average height, 165 cm. So, this was clearly a person of high status in his society." Photo by Clare Kendall/English Heritage

Okay, being I don't look good in tin foil hats, I will say I don't think time travel has anything to do with this. Obviously, one has to wonder if Nillson has a thing for Jeff Bridges though. I mean...he had to see the similarity himself, right?What do you think? Time travel? Ancient relative? Or artist cheated?

Of course time travel is possible. I move forward through time all the time.

Time travel is not ruled out by the laws of physics. Unicorns are also not ruled out by the laws of physics.

Time travel is not ruled out by the laws of physics. Unicorns are also not ruled out by the laws of physics.

That seems particularly authoritative coming from an Einstein avatar.

Einstein's general relativity has solutions that allow for time travel (wormholes). But traversable wormholes would require exotic forms of matter (unicorn meat, possibly) that physicists don't have any reason to believe exist. A lot of physicists also conjecture that causality is a thing the universe would want to preserve, but currently causality protection only emerges from other physical laws rather than being a law unto itself.

But... Interstellar!

Moving forward in time at different speeds: real
Moving backward in time: not real

But... Jung!

Wh0t Jung?

1. Journalists are rarely competent when it comes to science
2. Sometimes a journalist gives the wrong (unscientific) explanation to some discovery that has a correct, rational, scientific explanation.
3. Don't think that because the journalistic explanation is wrong that the real scientific discovery behind is BS.
4. According to the article, all infos of his whereabouts are in his teeth.
5. He was born in one place and moved at the age of 2 to some other place.
6. After some checking, it appears all primates have no teeth at birth, and grow baby teeth after some time. Baby teeth are replaced after some time.
7. I have all reasons to believe that this 6.000y old human got and lost his baby teeth very, very close to when modern humans do (http://www.orajel.com/en/Resource-Ce...h-Will-Come-In)
8. I am sure that his birth location info was not 'found' in his (non existing) teeth and his 2y old whereabouts were probably lost with his baby teeth.
9. Most probably the journalist did not get the explanation correctly.

Wh0t Jung?

You know... Carl Jung... Time is a landscape, like in dreams.

Interestingly, Dry, the issues you cite are from the direct quote from the archaeologist, Oscar Nilsson. While some science writers get some of the science wrong, it seems that internet critics of science writing are as bad, if not worse.

Moving backward in time, to me at least, implies not just moving backwards but moving in two different dimensions labeled time. There's the one dimension time that all travel implies in the "at time A I'm at point A, at time B I'm at point B" sense, and then there's the actual medium of history you're supposed to be traveling through. So, did the universe just politely generate this extra dimension for our traveling convenience, or what?

I suppose an actual physicist would tell me that the first sense is just some sort of illusion generated by my consciousness or something anyway.

I once did a thought experiment about what would happen if I encountered myself as a time-traveler who had come back from the future. The inescapable conclusion I came to was that I would, as a matter of self-preservation, be forced to kill my time-traveler self, before he took the chance to kill me.
