Could the projectile points show us a picture?

[gunny]

With a surveyor this morning walking my property on the east side of my canyon picked up a broken Pedernales projectile point. Nice veined chert from the Llano area. It occurred to me that in one of my physics or geology courses it was mentioned that certain minerals had the ability to retain light images. WOW sez I----Is it possible in the future my Pedernales could be inserted into DVD thingy and show its history? It has been a while(cough) since college, but I remember that. Will our technology be able to do this? Science fiction, of course, but so was flying within the memory of a lady 108 in a nearby town repoted today.

Looks as though I'm about to improve my education again. Gunny, what's a Pedernales projectile point?

[stan]

We had a weekly tv program here when i was a kid called "science fiction theatre."
Some one got scared because they thought they were seeing dinosaurs. The explanation was that some ancient rocks contained photos of dinosaurs, and that these were being projected on walls when sunlight
hit the rocks on the ground in a certain way. I thought that was pretty cool.

Oh man, Gunny. You're getting into science fantasy here. It's hard to imagine what scientific technology might be like in 100 years. I've seen articles that predict time travel by then. I'm not one to say that anything is impossible, so you might be right.

I'm certain though, that if it is considered remotely possible, the US military is working on it right now.

love the faith you have in your military machine even if I don't share it
but shouldn't they be working on an exit strategy first

[Digit]

Like long steps?

The U.S. military is really big on killing things right now and I doubt this technology would promote much of a budget. And don't give military labs too much credit for being creative. Theoretical physics is the realm of university and big-money commercial think tanks instead. There is a group in Britain who will provide genetic sequences on everything found on a tool for $6,000 per shot ... that's pretty cool. If a neanderthal was using the tool, etc. you could prove it once Paabo is finished with his genome project.

Retrieving information from time travel seems more plausable, but not in the conventional sense that you see in the movies.

either you know something I don't (likely) or I'm worried for your sanity with that last comment Patrick
unless you mean the usual type of time travel that happens everyday to everyone
i.e. forward at a normal pace

Exactly. OK, class ... give Marduk a gold star. Marduk, as you know time and distance are linked. Or should I say time and space? Alright, turn to the next chapter and start reading about this German of Jewish descent:

Never could happen in the manner in which it's portrayed on film.

what no delorean

im almost dissappointed

Sorry, Marduk. No Delorean. Einstein's Theory allows us to view the past but not while being there. That's the paradox, we cannot return to the past since just being there would create a different universe.

Consider being 100 light years away with a super-sophisticated receiver pointed at earth. If you dial into the proper photons you'll be watching earth 100 years ago. How do you get there to do it? Einstein postulated a wormhole where time folds back on itself. You could theoretically move 1,000 or 10,000 lightyears out, whatever ... but you better have a really good computer or you'll never make it back home since home won't be in the same spot when you return (remember, it's moving ... fast).

Oh, and bend time a lot so you don't travel too fast through the wormhole. Otherwise, you won't age as fast as others back home. The closest movie I've seen that mimics Einstein's theory is Dune.

then perhaps you should watch Donnie Darko

Gave up on TV years ago ... stunted my growth. Notice it hasn't stunted yours though, eh? When we plow through the space-time continuum, you're taking the front seat, alright? Personally, I would like to head back to Egypt circa 2650bce and take snapshots of the architects. We can communicate with them through ePSD, alright?

[Digit]

Personally Cog I'd like to return to my youth. I might be able then to avoid some of the mistakes I made. In addition Cog and Marduk, don't blame the armies of US or UK, blame the poilticians. Remember both, if you ever experience a major disaster, (and survive it), it will probably be a soldier who digs you out!

Actually, Digit, there is a world of difference between the attitude expressed towards soldiers during our Vietnam debacle versus today. Americans now support the troops regardless since it is obvious that the politicians put them in harm's way. As you could expect, almost none of our congressman's or senator's sons serve in Iraq (I am only aware of one who has). One out of 535 families is not leadership.
