Why does mass slow time?

[gravityblock]

Massive objects take a path of greatest proper time or spacetime distance, and light takes a path of least (zero) spacetime distance, provided they are acted on by gravity alone. The reason why light takes a path of least (zero) spacetime distance is because the frequency is very high and the wavelength is very short. If you increase the mass/energy you increase the frequency and the wavelength is shorter. Massive objects takes the path of greatest spacetime distance or proper time because the energy is not as high as light and hence a longer wavelength. The frequency simply describes the number of oscillations or cycles per second, while the term wavelength describes the distance between one wave and the next. Hence wavelength and frequency are inseparably intertwined: the higher the frequency the shorter the wavelength.

Planck's formula: E=hf where:
E is the energy of a single photon,
f is the photon's frequency,
h is Planck's constant,
Einstein's formula: E=mc2 where:
E is energy,
m is mass,
c2 is the speed of light squared,
hence, hf=mc2

thus showing that the energy/mass of a photon is directly proportional to the frequency of the photon.
E=hf and E=mc2 so hf=mc2

1)mass/energy
2)wave/particle
3)space/time
4)frequency/wavelength
5)electricity/magnetism

frequency = energy/mass
wavelength = time

In order to understand this, you need to change your thinking of time. It has nothing to do with how fast the earth is orbiting the sun or how long it takes to make a revolution. 1 second of earth time is 9,192,631,770 cycles of radiation corresponding to the transition between two energy levels of the ground state of the caesium-133 atom. This definition makes the caesium oscillator (often called an atomic clock) the primary standard for time and frequency measurements. If you know the frequency, then you know the wavelength, and you also know the energy/mass, they are all related.

Gravityblock,
Will you explain what the connection is between the speed of light and the amount of energy in something?

[christo4_99]

the bound atom has potential energy insomuch as it is not interacting with the environment,when the constituent parts of the atom are freed the total mass becomes active  with the environment thereby releasing the energy of the total weight at the maximum speed which is the speed of light.

Gravityblocker,
If light travels at the speed of light and things that travel at the speed of light have infinite mass than light must have infinite mass. Does light have infinite mass?
E = MC² is junk

Light has a relativistic finite mass. Remember a photon is massless, a photon's rest mass is zero.

An object cannot be accelerated to the speed of light, regardless of how much energy it absorbs. Its momentum and energy continue to increase, but its speed approaches a constant value â€" the speed of light. As the object approaches the speed of light, the relativistic mass tends towards infinity. When a force acts in the direction of motion, the relativistic mass goes up and the momentum goes up, but the speed hardly increases.
