Planck Length Quotes

The role of the infinitely small in nature is infinitely great.

Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.

All kinds of physical considerations become senseless when we try to apply them to distances smaller than 10 -13 centimeter.

As far as extra dimensions are concerned, very tiny extra dimensions wouldn't be perceived in everyday life, just as atoms aren't: we see many atoms together but we don't see atoms individually.

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.

Quantum physics thus reveals a basic oneness of the universe.

To us large creatures, space-time is like the sea seen from an ocean liner, smooth and serene. Up close, though, on tiny scales, it's waves and bubbles. At extremely fine scales, pockets and bubbles of space-time can form at random, sputtering into being, then dissolving.

By getting to smaller and smaller units, we do not come to fundamental or indivisible units. But we do come to a point where further division has no meaning.

It is at least scientifically respectable to postulate that at the centre of a black hole the laws of nature no longer apply. Since most scientists are just a bit religious and most religious are seldom wholly unscientific we find humanity in a comical position. His scientific intellect believes in the possibility of miracles inside a black hole while his religious intellect believes in them outside it.

Time, matter, space - all, it may be, are no more than a point.
