Basic particles thus appeared, lived out their mortal spans, and then vanished.

If these particles appear for very short times it appears that they can violate energy conservation a little.

The particle that escapes appears to have been emitted by the black hole.

The very small particles of silver metal appear to be black, with a 'red' shade.

And so must the particles appear to be like and unlike themselves and each other.

And it turns out that only particles whose wavelengths can fit a whole number of times into the gap between the plates will appear there.

Schr6-dinger's equation described the set of probabilities about where the particle would appear next.

The essence of the problem was, what made the particle appear in only One spot?

Here, tiny particles of light called photons appear to change form at random.

These particles must not appear as the end-states of a scattering process.
