planck mass造句

• Ther fore, Planck mass is about 4?0 22 electron masses.
• The mass scale is at most the Planck mass.
• So 1 kg is about 45 million Planck masses.
• The Planck mass, for example, is about the same as that of an ant.
• Where G _ D is the Newton constant in D dimensions and M _ p the corresponding Planck mass.
• While not as unimaginable to us as the Planck length, fleas would then be a whopping 5000 Planck masses.
• The value chosen for a unit of the Planck temperature is that corresponding to the energy of the Planck mass or.
• For ordinary electromagnetism, the upper mass bound is not very useful because it is about same size as the Planck mass.
• :: : That's the Planck mass; the black hole would be roughly equivalent to a gravitationally collapsed flea.
• However, in some scenarios involving extra dimensions of space, the Planck mass can be as low as the Pb Pb collisions.
• It is Planck force only for the Planck mass ( approximately 2.18 & times; 10  " 8 kg ).
• :That analysis relies on semiclassical theory, and only makes sense for black holes with masses much larger than the Planck mass.
• Unlike all other Planck base units and most Planck derived units, the Planck mass has a scale more or less conceivable to humans.
• This follows from the fact that the Planck length is a reduced Compton wavelength equal to half the Schwarzschild radius of the Planck mass:
• :In Planck units the unit of mass is the Planck mass, which is about 2.2 x 10-8 kg.
• If two quanta of the Planck mass or greater met, they could spontaneously form a black hole whose Schwarzschild radius equals their Compton wavelength.
• \alpha _ G has a surprisingly simple physical interpretation : it is the square of the electron mass, measured in units of Planck mass.
• This is dimension-six, and it contains one power of the Higgs expectation value, and is suppressed by two powers of the Planck mass.
• Like the planck length, but for mass ( and not the planck mass ! ) talk ) 15 : 55, 30 November 2011 ( UTC)
• Note that in terms of the Planck mass, we set \ hbar = c = 1, whereas the last term keeps all the SI unit factors.
