Of the four fundamental forces, gravity is the one we’re most familiar with in our everyday lives, but perhaps surprisingly, it’s the weakest and hardest to measure here on Earth. Now, physicists in ...

In this case, we can say that reconciling gravity and quantum mechanics is a big unknown, and likely to have some practical applications we can't anticipate. With that as a goal, we can then ...
