For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...

A few weeks ago we discussed a new theory of gravity that has been hotly disputed and debated since it was formulated a few years ago. Now, a new set of astronomers has produced observations that are ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

Gravity is one of the four fundamental forces of nature, which means it’s not derived from anything else – it just is. At least, that's according to our presently accepted theories. But this may be ...

The newly developed theory of emergent gravity, proposed as an alternative to dark matter, struggles in one of its first trials. Kris Pardo, a graduate student working under the astrophysicist David ...

The Universe is a strange place. Apart from the normal matter that we see around us, there appears to be a far larger amount of matter that we cannot see—the infamous dark matter. Even more puzzling, ...

I've long wondered what the difference is between (1) the universe being a hologram and (2) the universe is 4D (space+time) but the rules can be more easily manipulated mathematically if we first map ...
