  • Science can allow us to determine what happened trillionths of a second after the Big Bang.
  • But it likely never will be possible to know what brought about the Big Bang.
  • As frustrating as it might be, some things are entirely unknowable. And that's a good thing.

  • A new study claims networks of observers are responsible for determining physical reality.
  • The scientists propose that observers generate the structures of time and space.
  • The paper could help yield insights into the God Equation, which attempts to unify quantum mechanics and general relativity.

A big lesson from the ‘Oumuamua alienware controversy

Scientists should be cautious when expressing an opinion based on little more than speculation.

  • In October 2017, a strange celestial object was detected, soon to be declared our first recognized interstellar visitor.
  • The press exploded when a leading Harvard astronomer suggested the object to have been engineered by an alien civilization.
  • This is an extraordinary conclusion that was based on a faulty line of scientific reasoning. Ruling out competing hypotheses doesn't make your hypothesis right.
