Ancient Mysteries

  • We are currently upgrading MFK. thanks! -neo
Science channel has a show(can't remember the name) where they go around and try to find stuff underground so, they use lidar alot.

I don't know how many of you guys have read Asimov but he had some interesting ideas about the colonization of the Galaxy.

One of the ideas to which I ascribe is that it may come back to haunt us. If we send out space-faring civilizations that turn around and eventually return to conquer Earth, we may be very sorry we fostered them to begin with.

Another one of his ideas was that robots would proliferate in space and other planets but would become illegal on Earth.

We have the technology to put truck drivers out of work, through robotics, and when you stop to think about the fact that driving a truck is one of the largest professions on the planet this becomes a very interesting situation.

But if eventually the computers get good enough that they can drive better than human beings, we will have fewer traffic deaths and more time to do important things. Like talk on cell phone, which is what everyone seems to want to do in the car.

Back when I was riding a motorcycle to work everyday I would have somebody every week try to run me over while talking on the cell phone, putting on makeup, etc.
 
Regarding the ruins of Gobekli Tepe I always assumed such underground communities were designed to evade the desert heat. You mostly find them in the tropics, which is where the civilization was back then due to heavy ice packs at the poles.

But it appears that that City may have been filled in on purpose. An archaeologist has speculated that it was the residents that did this.

I don't think that's the case at all.

Typically when a civilization conquered another one it destroyed their buildings and statues and monuments and flags and evidence of that culture. They smashed the nose off the Sphinx, they tore down the statues of Roman emperors, they pulled down the statue of General Lee.

This is typical Behavior but at Gobekli Tepei this thing to do was just fill in the hole and that's what they did. They destroyed the entire city by filling it in with rubble from bottom to top.
 
By the way, I have no doubt that human civilization can have risen and fallen repeatedly in the course of geologic time.

Young Engineers are always accused of trying to reinvent the wheel but I'm pretty sure that humans have done exactly that, more than once.

The thing is there are no good records for Mass natural catastrophes except the geologic evidence we can dig out of places that have been hit, and the ancient legends of such things which survive in the history of various cultures around the world.

Many cultures have stories of great floods and great earthquakes and great disasters of the past. the fact that human being still exist means that some of us escaped to tell those Tales.

I am 100% certain that this will happen again and that only a fraction of humanity will escape destruction.

Everybody's worried about global warming that could kill us all off in another Century or two, but we take no account of the fact that an out-of-the-ecliptic asteroid could smack into the Earth and put the survivors in an ice age in a matter of days.

Is it possible that ancient civilizations developed things like anti-gravity fields and cold fusion?

First you have to consider the rise of technology in our own situation. We went from beating out steel plates and rivets with a hammer, to Hot Drop forging, to computer-controlled 3D "printing" in a few hundred years. In another hundred years the situation could be equally astonishing.

Should we survive.

you only need to look at the Moon to decide that there have been a lot of asteroid strikes in our past. After all, the Earth attracts asteroids six times as strongly as the Moon.

Over the eons the pummeling has abated, but there is no reason to believe that most life on Earth won't be extinguished by a big rock falling from the sky.

A large volcano eruption can do it too.

Mars is too far and too cold you know. We need to have a habitat built right around Earth. Around the Moon. On the moon.
Right now all our eggs are in one basket.
