In a vacuum, yes. BUT light is affected by gravity. And gravity is affected by density. And the speed light travels at does vary according to the medium (usually a vacuum of course).

My problem with the "gains mass" idea is that this would require easily changing energy into matter and then BACK, easily! Bzzt!

I think it`s easier to change the speed of light (via density) than to convert mass & energy around. Just like I can "move the moon" eh?

[quote]The Energy increases, the Mass stays the same so the Speed of Light (squared) is INCREASED to keep it balanced...[/quote]

I did get it "arse backwards" in my explanation below, it <increases> due to more density (gravitic effects). SPEEDS UP in a "relative way" eh?

Again, it`s such a tiny number it`s incomprehensibly small!

"bla bla bla.. (assuming a perfect vacuum)"..

In a perfect vacuum, it`s about 42 minutes to fall through the earth to the other side, only by the influence of gravity. Drag messes up all the beautiful math. Stop ruining the cool physics !..

5Cats: The entire theory of relativity is based on the assumption that the speed of light in a vacuum is a universal constant, and does not depend at all on how you`re moving through the universe, or what kind of field you`re in. So no, the speed of light doesn`t change.. therefore, the mass must.

If you compress a spring, you add potential energy to it by distorting the molecular bonds away from their ground state. when you release it, it jumps up, because the molecular bonds go back into their original configuration. This stored potential energy is still real energy, and still factors into the E = m*c^2 equation..

The Energy increases, the Mass stays the same so the Speed of Light (squared) is reduced to keep it balanced...

The higher density alters the fabric of space/time which slows light (in that RELATIVE way, eh?).

More density = greater distortion in the space/time field which affects... the speed of light! After all, it`s not a "constant" it`s subject to various variables, including dents in the fabric of space-time.

Again, it`s literally impossible to measure as it is such a TINY number.

Just like when you move a 10 pound weight you`ve moved the Moon. You can calculate it... but never measure anything THAT small! Not to mention 1,000 other unknown variables...

Get your facts straight and shove the `murica bullpoo up your wanker ass.

and one trillion = 1.000.000.000.000.000.000

Sometimes I think `muricans use those words because they just sound fancy.

A compressed spring does have a bit more mass due to stored energy. HOWEVER. the amount is so small you could never measure it.

Say: 1000 J = 1000 kg*m^2/s^2

E = Mc^2

1000 = M * (3 * 10^8)^2

10^3 = m * 9 * 10^16

M = 1 * 10^3/9* 10^16 = 0.11 * 10^-13 kg = 0.00000000000001 kg

I did not just copy/paste that from yahoo answers...

How can a spring weigh more when compressed.

You`re not counting the weight compressing it, just the spring itself. ... I don`t recon that one.

"Lets think bigger: if you dug a hole to the center of the Earth and dropped a book Down, it would take 45 mins to Reach the bottom:"

Well if you want to be technical, its not stated where exactly this bottom is.

The gravitational pull also varies depending on Your distance from the Source.

So even if we were at the bottom of this hole, its unlikely that it would take 45 minutes as the gravitational pull would be greater than on the surface.

that`s why it bugs me when I hear that space is `the final frontier` (despite being a Star Trek fan) ... nope, we still haven`t fully explored the oceans yet. AFTER that it`s space.

A very quick calculation sets the random fact to be quite off.

The average radius of Earth is about 6371 km.

Assuming the terminal velocity of a book is ~200km/hour the same as any given Object without effecient friction reducing facilities.

6370000m/200000m/hr = 31.9hr =1.3 days

Assumptions: 15 Seconds to Reach terminal velocity not taken into consideration but this would add time not reduce.

Variance in air friction not taken into consideration but this would likely slow it Down further.

Re-reading your text I wonder if you have not taken into account terminal velocity? The book has a drag coefficient that slows it - it cannot reach that speed. It will initially accelerate a 9.81m/s2 until the drag overcomes the acceleration.

I heard something... in stereo! (stereo!)

(get it? My wordplay of the day!)

I was about to agree, but then I thought: there`s 3 ways to "store energy"

- mass

- heat

- kinetic

Doesn`t the compression of the spring simply ADD kinetic energy? As @stk5m wisely points out: not one single atom of mass is gained... electron even!

The E=Mc^2 is a simplification which requires OTHER variables (like momentum for example, which is a form of... kinetic energy!) to be constant too. Or zero...

It was on IAB before!!! (lolz!)

What? You didn`t like my explanation? ;)

Actually, the compressed spring contains energy. That energy has an equivalent mass m = E/c^2, which is quite small but still greater than zero.

E=MC2

A compressed spring contains more energy than an uncompressed one. To balance the equation mass must increase, although EXTREMELY little, because c is constant.

Weight is mass x gravity so a higher mass equals a higher weight.

No, I`m not looking it up! Lazybones...
