  >Watch out if you would meet an alien. You could be infected with a disease with which you have no resistance.
  
  Wrong, disease agents are very specialized and we would be immune to those which evolved to target alien organisms.
  
  Hes the most overrated scientists alive, if it wasn't for his ALS, almost no one would bother with him. And whats most annoying is that he himself is responsible, in one of his articles he even placed himself as an equal to Albert E ROFL!

  Is the New World more happy than the Old? Yes, because now we have democracy. And modern medicine. But scientists bring more and more uncontrollable risks - are they science addicted like alcohol drinking and smoking?

  Alone in our galaxy - today?
  
  A simple solution to the Fermi Paradox - why we haven't stumbled onto some alien broadcasts in space - may be that our Sun seems to be an "afterthought".
  
  Any electromagnetic signal, which has been transmitted from even the most remote point in our galaxy more than 100,000 years ago will now have left the galaxy forever.
  
  Most stars in our galaxy seem to have been created some 7E9 to 9E9 years ago. Our Sun is only about 4.6E9 years old.
  
  According to the present star models, when our Sun reaches the age of about 6.5E9 years the market for long johns will be exhausted - the oceans will have evaporated and life as we know it will be extinct.
  
  Assuming that an extraterrestrial civilization reached Earth a few E9 years back, even if they did build observation stations on Earth, plate tectonics may well have removed any trace of this incident.
