What was the need to invent the H-bomb and atomic bomb?? Just to kill innocents, or to be a cause of earthquake and depletion of any layer of our atmosphere!!! I don’t think it has a single good reason.. I just don’t understand why we invent such kind of technology and now it’s not even easy to detect a nuclear weapon… So it’s a failure or a success!! What North Korea wants to prove now? What are we gonna achieve by all these disaster things… There are many problems in this world wars, hunger, disasters it’s better to use power for the sake of people.. Try not to solve them don’t try to create new one!!!
Thanks to Babylonians for giving such a useful thing to us calendar.. But believing in zodiac signs is a stupidity in my perception.. Movement and position of stars are astronomical events and they have nothing to do with our daily routine predication… It’s just a superstition…
