Construction needs cloud flexibility

Australia’s embattled construction sector could benefit from cloud based information systems that can be switched on and off in lockstep with individual projects – with the exception of those organisations based in remote areas like the Kimberleys.

Hawking thinks space aliens might be trouble

Science - Space

British astrophysicist Stephen Hawking lectured in the United States on April 21, 2010, and commented on the existence of intelligent extraterrestrial life. He thinks such aliens are fairly rare but probably out there. But, they might be a threat to Earthlings.

 


While giving a lecture at George Washington University, in Washington D.C. (as part of NASA's 50th anniversary celebration), Stephen Hawking hypothesized on whether or not extraterrestrial life exists out there in the universe.

Dr. Hawking conjectured that three possibilities exist as to whether intelligent space aliens live out there in the universe.

1.    Probably Not, no other intelligent life out there.

2.    Yes, but if they are intelligent enough to send us signals they are probably also intelligent enough to have weapons of mass destruction (kinda like us humans here on Earth) and be a serious threat to Earth.

3.    Yes, intelligent life exists in the universe but it is only fairly rare; however, primitive life is very much more common.

According to the April 23, 2010 Fox News article 'Primitive Alien Life May Exist, Stephen Hawking Says,' Dr. Hawking stated with respect to his third option: 'Primitive life is very common and intelligent life is fairly rare'¦. Some would say it has yet to occur on earth."
