The cosmos may be studded with black holes so tiny they could slip in between atoms, a wild new theory suggests.
And we could be making these teensy singularities all the time at the world’s largest atom smasher, a new study shows. If we could make these objects, they could be a window into the mysterious nature of gravity.
We have four fundamental forces of nature (at least, that we know about so far): electromagnetism, strong force, weak force and gravity. All four forces operate at different ranges, have different carriers and interact in different ways. They also have very different strengths.
And no matter how you slice it, gravity always comes out the weakest. Gravity is such a feeble force that if it were a billion billion times stronger than it currently is, it would still be the weakest force by a factor of about 10 million.
