Not sure if this the right place to post this so MODs please move accordingly if required.
I did a search and couldn't find anything (search function not working for me right now..) so if this is a duplicate thread, I apologize and mods
will do what they do..
I came accross this
on CBC News and though I would post it since there is a lot
of talk about the said subject in the past weeks or so.
... there are signs that a huge crater buried deep under the East Antarctic ice sheet was caused by the largest piece of space rock ever to hit the
Earth. Magnetic imaging shows an impact area about 500 kilometres in diameter. That would indicate a meteor nearly 50 kilometres wide.
A rounded landform on the northwest shoulder of Mexico's Yucatan peninsula is all that can be seen of this giant impact site. Scientists speculate
that a celestial object some 10 kilometres wide smacked into the area 65 million years ago. That's estimated to have caused an explosion equivalent
to 100 trillion tonnes of TNT, or five billion times larger than the atomic bomb dropped on Hiroshima in August 1945.
Deep beneath the Canadian Shield, miners from this city toil to extract seams of nickel and copper exposed when a meteor the size of Mount Logan is
thought to have slammed into Earth some 1.8 billion years ago.
Literally speaking, there was no physical impact here when a massive explosion in 1908 levelled trees, broke windows and caused casualties over a wide
area of Central Russia. Eyewitnesses report seeing a brilliant blue light streak across the sky, followed by series of loud bangs.
Arizona meteor crater
A relatively small chunk of matter from space crashed into the Arizona desert between 20,000 and 50,000 years ago.
The crater is just over a kilometre from rim to rim, which indicates a space projectile about 40 metres in diameter.
100km (62mile) wide crater discovered in Greenland - and it is possible crater is more than 500km in size
Finnefjeld mountain, which is around 1050m high, is believed to be the crushed core of the structure
The dull grey rocks were crushed to fine powder by the impact, and then cut by white melt sheets
Obviously I do not need to go back into the meteor shower of the past week because I think that this has been covered in depth already.
Now I am aware that there are many many more cases but still, I will stop here. I have been reading a lot of Articles/documentaries about this as it
fascinates me. And well....that got me thinking....
Uh Oh!!! I am thinking...
Now what are the odds of a Global Killer to strike us? Again? Not too good apparently but history shows that it has happenned before and could/will
just as easily happen again. In the near future, in a year, a hundred years, a million years, who knows?
But what are our options if we spot one heading right for us?
How Do We Stop Asteroids From Destroying Earth?
The method used to prevent a cataclysmic disaster will depend on how large the object in question is. ..., but there are still things that we can
Nuclear Bomb: to detonate a nuclear weapon, or some other powerful bomb strategically near the object. The blast would knock the object off
Rocket Motor: Alternatively, a rocket or motor could be attached to the object, and used to drive it onto a new course.
Solar Sail: The solar energy from the sun can actually apply pressure on an object. So a sail could be attached to the object to harness the solar
wind, similar to how we use sail boats here on Earth, and divert the course of the object that way.
Break The Object Up: NASA could also use a weapon to break the object up into smaller pieces.
The problem is that these defenses are not in place, some of them only exist in theory.
So there are a few options that could save us "in theory". But if this meteor shower we just had is a precurser....and the big one is near.....we
are in for quite a show aren't we. Because there is not much that could be done on short notice except to bend over and kiss your *** goodbye !!!
I wonder if there is actually a defensive measure in place
that "they" dont tell us about? Because just telling the general population about
it could cause histeria as people would likely automaticaly assume one IS coming.
Any thoughts ATS?
