So the mass is increased. Same feeling. When two objects are closed together, when the velocity is higher, two objects meet more stronger and it means gravitation is increased. So when the mass is bigger, the gravity is increased.   Sep 16th 2013, 06:10 AM   #2

What you're describing is the effect discovered by Sir Isaac Newton, that as the momentum of an object increases it takes more force (or time) to bring it to a stop. This effect is described by the Newton's 2nd Law: The product of mass times velocity is called momentum. Increasing m, or increasing v (or both) increases rthe object's momentum and consequently either a greater force is needed or it takes a longer period of time to make the change using the same force.

Sorry, but ths is incorrect - at least at non-relativistic velocities. I am assuming from the way you phrased this that you are not referring to the effects predicted by Special Realativity on the mass of objects traveling at near light speed. Mass and velocity are not the same, although both contribute to an object's momentum. There is no evidence that an object's velocity has an effect on the the force of gravity. As evidence that Newton is correct - all of the various space missions to the moon, Mars, Jupiter have all been planned and executed using Newton's Laws, including the law of gravity: Note that velocity is not a factor. If mass was a function of velocity every one of those missions would have gone seriously wrong. So there is proof-positive that at "reasonable" velocities (speed at which space probes fly) gravity is not influenced by speed.

May I be the first to say "WTF??"

What are all these a's and b's?

That's a scientific term, and appropriately used here!

If there is something, Kg is Blackhole, and Space is M/Sec. So Space is nothing only for logic. KG(Blackhole) is the absolute fact. So Same condition in Light speed and normal speed. E=MC^2 1KG*(M^2)/(Sec^2)=1KG*(C^2) 1(M^2)/(Sec^2)=1(C^2) 1M/Sec=1C So Light speed is the truth.   Sep 29th 2013, 08:19 PM   #7

What does this have to do with your original post? I can't see any connection.

"space" is m/s? I'm not sure what you mean by this...most people talking about space would consider it to be a volume, so the units would be m^3.

And if you are using just the units then yes, the units will match on both sides of E = mc^2. If it didn't we'd all be in a lot of trouble!

"light speed is the truth?" What does that mean?

I'm guessing you are not a native English speaker. You might look into finding a good translator program.

Unfortunately that logic doesn't extend into your posts. The energy of 1 Kg of matter converted to enery using E=mc^2 yields a lot more than just one joule of energy. Actually it would yield 9x10^19 Joules of energy, equivalent to about a 12.5 thousand megatons of TNT.
