Differences in views of scientists regard to two more important questions - how is it valuable for science, and how dangerous?

Indeed, the value of the banner is that its code laid technologies of the future. Explanation of these codes is now actively engaged in physics from NASA

Physicist Michael Dodzhenson (NASA):

"... This will enable us to move away from dogmas theory of algorithms, and build new processing technologies and visual display of information (at least) that in the future, perhaps even allowing transfer huge amounts of information even before it has" requested 'user. This will enable dramatically increased physical bandwidth channels and much more ... "

But with such an approach strongly disagree scientists fear that is not always trying to explore the complex and incomprehensible phenomenon ended well, and for the benefit of society (such as splitting the atom, which led to the creation of nuclear weapons)

Professor Isaac Shamel (Israel):

"... In the black banner, no doubt, laid the danger - it is not known who and what objectives it has set up. And even the opportunity to explore new technologies can not justify the potential danger ... "

These cautious and skeptical scientists put forward different versions of its origin - including, and his version of 'extraterrestrial' essence - as a conscious (alien beings) and natural (the nature of space).
