![]() And you're welcome.' And I wanted to make people work for that a little bit, I'd make it this sort of subtle-yet-universally observable thing," Brande said. "If I was a creator and I wanted to delay the slam-dunk evidence of, here is the message that says 'Hi guys, I created the universe.

It's almost like writing different sections of a newspaper for different audiences."Īnother advantage to hiding a message in the CMB for a would-be cosmic creator is that right now, the CMB is visible from almost any vantage point in space, said Yoni Brande, a University of Kansas astrophysicist who also wasn't involved in this paper. "It all depends on what level of intelligence you want to approach. The CMB is a good option because we've been able to detect it since the first good microwave study of the sky in 1964, as opposed to, say, gravitational waves, which require more technical equipment and we only detected in February 2016. "There could be different media on which you'd encode the message," Loeb said. And you're welcome.' And I wanted to make people work for that a little bit, I'd make it this sort of subtle-yet-universally observable thing Yoni Brande, University of Kansas message that says 'Hi guys, I created the universe. Leaving aside all the hidden assumptions in the question - that there is a cosmic creator, that a cosmic creator wants people to know about them, that the cosmic creator has an insight into the minds of future intelligent creatures and can therefore predict the future - the CMB would be a good place to hide a message if you were a creator trying to target civilizations at our current level of development, said Avi Loeb, a Harvard astrophysicist who wasn't involved in Hippke's work published to the arXiv database on Nov. Michael Hippke, a self-described "gentleman scientist" affiliated with the Sonneberg Observatory in Germany, went looking for a sign from a creator in that background radiation. Physicists have long studied the CMB looking for features that might offer clues about the structure of the universe. They form a background radiation pattern across the whole sky. Its microwaves have been traveling since the first atoms formed out of a haze of protons and electrons that filled the universe soon after the Big Bang. The CMB is the oldest light in the universe, visible across all of space. A search for a message on "the most cosmic of all billboards, the Cosmic Microwave Background (CMB)," has failed, a new study finds.
