This is all over the Internet, of course. I want to post this article link from RT (Russia Today) and include a very interesting quote from a resident:
Chelyabinsk residents have also reported “unusually high sun activity.” Some said the local Miass River has a layer of steam above it, and is apparently evaporating. “Stock up on water, people, Miass starts to evaporate!” one local resident wrote online.
Oh, and here is the link to the American Meteor Society for reporting fireballs:
I am going to make a statement here: I believe there are those who have technology to change an asteroid’s trajectory or to blow it up in outer space or inner space if desired. I don’t have any inside knowledge, I’ve come to that conclusion from reading various materials on the Internet over many years.
