"Aliens can be hostile"
British astronomers and Scientist warns!

Scientists are doing their best to find intelligent life in space.
But now experts warn of the consequences.
- The consequences of a contact need not be what we hope for. We need to engage the UN and governments in these discussions, says astronomer Marek Kukula.
Marek Kukula is an astronomer at the Royal Observatory in Greenwich. He says the Sunday Times that, "a part of me agrees, and enthusiasts would try to establish contact with a wise, peaceful civilization."
But the warning display:
- We like to think that if there is intelligent life out there, it is wise and sympathetic - but of course we have no evidence for it, says Kukula.

He says the UN and world governments must be involved in discussions. This week a conference was held in London on the topic: Discovery of extraterrestrial life and the consequences of the Science and Society.
Professor Simon Conway Morris, an evolutionary biologist at Cambridge University, presented his lecture on, the foresee of how extraterrestrial life might look like - and prepare for the worst. He said that from a Darwinian approach, it is "inevitable" that intelligent life has evolved in other places where there is a precondition for it.

Assumed technology :
"If it is true, there are also alien technologies", says Conway Morris. Some scientists are puzzled that we have not received any messages back - even though the men have sent TV and radio signals over the past century.
"- But I'm not sure I would pick up the phone if I were in their shoes, "says Simon Conway Morris sarcastically.
