Explanation for gravity and mass?

[IvorGeorge]

Facts
• Speed of light = 300,000 km/sec
o http://en.wikipedia.org/wiki/Speed_of_light
• Furthest observed galaxy = 13 billion light years away
o http://en.wikipedia.org/wiki/Speed_of_light
• the Universe has a calculated age of 13.75 ± 0.11 billion years
o http://en.wikipedia.org/wiki/Big_Bang

Deduced facts
• Furthest observed galaxy is close to the origin of the big bang, or be at close to right angle to it
o Therefore we on Earth must be traveling through space at a speed relative to the big bang origin at close to speed of light
• Majority of objects moving away from us have relative speed > speed of light – therefore they can not be observed
o Explanation for missing 'dark' matter?
• E=mc2 sees mass approaching infinity as speed approaches light speed
o Explanation for gravity?
• Hunt is on for the Higgs particle that will explain how most of the known elementary particles obtain their masses
o Is it possible that E=mc2 explains this already?

Welcome to Physics Forums IvorGeorge!

You have some interesting ideas, and I can't fully explain/endorse all of them because I don't have a complete knowledge of all of this, but I think I can talk about some of these.

One thing that is apparent in some of your points is the 'origin of the big bang'. Now my guess is that you are aware that all galaxies are moving away from each other, and you logically deduce that they are all moving away from the initial point. However it's a bit more complicated than that, it's not that all objects are moving away from each other, but that space itself is expanding. So they are not moving away from a central point, but rather the big bang happened everywhere at once, but while the universe was a much smaller place. So while everything is moving away from each other, they are not moving away from a central point.

As for the others, I only have 2 minor points. The first is that while it can be assumed that a large percent of the universe is farther away than the observable universe and therefore cannot be observed, the gravitation force is not instant, but rather moves at the speed of light, therefore if we can't see it, we can't feel it. The second is that Mass in the classical sense does not increase as velocity increases. Rather the relativistic mass increases as velocity increases, but Relativistic Mass does not influence gravity, only the rest mass does. I believe the fact that a object gets heavier as it's speed increases is a common misconception that is the root of a lot of misunderstanding.
