| 1. | Ther fore, Planck mass is about 4?0 22 electron masses.
|
| 2. | The mass scale is at most the Planck mass.
|
| 3. | So 1 kg is about 45 million Planck masses.
|
| 4. | The Planck mass, for example, is about the same as that of an ant.
|
| 5. | Where G _ D is the Newton constant in D dimensions and M _ p the corresponding Planck mass.
|
| 6. | While not as unimaginable to us as the Planck length, fleas would then be a whopping 5000 Planck masses.
|
| 7. | The value chosen for a unit of the Planck temperature is that corresponding to the energy of the Planck mass or.
|
| 8. | For ordinary electromagnetism, the upper mass bound is not very useful because it is about same size as the Planck mass.
|
| 9. | :: : That's the Planck mass; the black hole would be roughly equivalent to a gravitationally collapsed flea.
|
| 10. | However, in some scenarios involving extra dimensions of space, the Planck mass can be as low as the Pb Pb collisions.
