For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Could the vast universe in which we live actually be the interior of a black hole within a larger universe? The idea, which ...

According to the theory, our reality is encoded on the boundary of a black hole within a much larger universe.

If true (and it’s a pretty big “if”), Vopson’s new gravitational study would shake the foundations of the currently accepted view of the universe. In his paper, Vopson writes that his new work could ...

(via Sabine Hossenfelder) The second law of thermodynamics says that entropy will inevitably increase. Eventually, it will make life in the universe impossible. What does this mean? And is it correct?

Thermodynamic spontaneity—whether a reaction can go—can be measured by changes in either of two parameters: entropy or free energy. These concepts are abstract and can be somewhat difficult to ...
