The speed limit squared and mass |
Why is it that the speed limit in the
universe squared is the amount of energy
in mass?
Mass is bound or concentrated energy.
Why the square of the speed of light
and not some other quantity?
God gave more meaning to the speed of
light than meets the eye.

Given the choice between God and a ham sandwich, which should one
choose?
Answer: the ham sandwich. Nothing is greater than God, and
a ham sandwich is better than nothing.

Do the math. c^2 is the result of the Lorentz transformation (where
apparent length, time and mass vary as an object approaches the speed of
light).
If you push on an object (adding energy to it), it accelerates. As it
approaches the speed of light, it gets heavier (according to an external
observer). If you work out how the object's momentum changes due to this
energy input and the object's increase in mass, the m * c^2 term gives
the energy of the body at rest.
This has been verified experimentally by accelerating two particles
toward each other and measuring the energies of the products when they
collide and are totally annihilated.
Alternately, you could detonate a 20 KTon nuclear weapon, collect all of
the debris produced and weigh it. It will be approximately 1 gram
lighter following the explosion.
God gave more meaning to the speed of
light than meets the eye.
Sorry. I couldn't find the term for God in any of the related equations.

The speed of light is the time it takes to cross the universe
instantly.
The speed of light is the highest speed because one cannot cross a
distance
any faster than instantly.

Sorry, it's not as simple as that. It's not c^2. It's mc^2.
And as I stated earlier, if you were to actually STUDY relativity,
you'd know why c^2 is in there. You don't know, and so you haven't
studied SR anywhere NEAR enough to be dictating to people how things
work. You're a slob.

If you want to convert feet to inches, you need a conversion factor,
and so you multiply the number of feet by 12.
If you want to express an area in square feet to an area in square
inches, you need to use that conversion factor twice, like this:
2.5 ft^2 = (2.5 ft^2)(12 in/ft)^2 = 208 in^2.
If you want to express a mass in kilogram units to a mass in joule
units, you need to use a conversion factor, which in this case is
(2.9979E8)^2 J/kg = (2.9979E8 m/s)^2.
Now if you measure energy and mass in the same units (either kg or J or
eV or something else appropriate), then the numerical conversion factor
is not required at all.
It's as simple as that.

As measured from the source; if source and detector are co-moving, it
will be the same. If there is a relative motion between source and
receiver, then c'=c+v.
You will recognise whether such motion is happening when a change in
frequency is noticed. Analysis/measurement of the photon's velocity at
the receiver will indicate the relative velocity of source and
receiver.
NB: such measurement has NEVER been done!

As light velocity is c from its source, it varies otherwise, but the

Uh....KE = 1/2 mv^2 in Newtonian theory. This leads
to some discrepancies; for example, photons would
have momentum 2E/c in this theory:
KE = 1/2 m v^2
p = mv
2KE/v = (2)(1/2)mv^2/v = mv = p

G'day Ghost:
I have no doubt that photons DO have momentum-
I can't calculate what each is individually (say as a factor of
gravitational pull at earth surface), but the mental exercise is to
weigh something hot, then when it cools, and divide by the number of
emr particles which left the area :-).
There might be a problem with Newtonian KE at that :-( it seems
trivially obvious that double velocity = double energy
(and note that I am not discussing _accellerating_ bodies; just making
comparison between identicle articles which may have been PREVIOUSLY
accellerated.
KE = 1/2 m v^2
p = mv
2KE/v = (2)(1/2)mv^2/v = mv = p
I draw your attention once again to M81:
I have not seen the claims that this jet is close to, or even greater
than c refuted. It now becomes encumbent on ALL DHR's to explain why
simple observation shows that shrinkage due to high velocity is NOT
evident, and NEITHER is a great and limitting increase in the mass of
the material composing it.

Hmmm. So what you're saying, Nick, is...
....that you're the world's least fallible interpreter of relativity
theory, yet you'ver never even studied it enough to know where c^2
comes from. You're even much more of a fool than previously indicated.

When you bring mass up to the speed of light it is energy. To get that
amount in three dimensions you cube it, which is the same as saying M =
C, so then E = MC squared is the same as M cubed, or made three
dimensional.
