Rafaela von Bredow and Johann Grolle in Der Speigel:
DER SPIEGEL: Professor Deutsch, you believe that mankind, after billions and billions of years of absolute monotony in the universe, will now reshape it to their liking, that a new cosmological era is coming. Are you serious?
Deutsch: I am not the first to propose this idea. The Italian geologist Antonio Stoppani wrote in the 19th century that he had no hesitation in declaring man to be a new power in the universe, equivalent to the power of gravitation.
DER SPIEGEL: And fly to distant planets? Tap energy from black holes? Conquer entire galaxies?
Deutsch: I am not saying that we will necessarily do all this. I am only saying that, in principle, there is nothing to stop us. Only the laws of physics could prevent us. And we do not know a law of physics that forbids us, for example, from traveling to distant stars.
