It is impossible to build a practical quantum broadcaster

A quantum broadcasting system would end up sending slightly different information to every receiver – and efforts to sidestep this problem are too inefficient for practical use

2H2KWEA Big Bang to Present. Stages in the history of the Universe after the Big Bang. At 300, 000 years, matter and radiation decouple, and the Universe becomes transparent for the first time. The first galaxies form at around 300 million years after the Big Bang, but the exact time period is uncertain. At an age of 9 billion years the Solar System formed. Finally, 13.7 billion years after the Big Bang we arrive at the present day. The Universe is still expanding and evolving.

Is gravity a new type of force that arises from cosmic entropy?

Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency to get more disordered. Now this idea might finally be testable
