Was Einstein right? Sorry I did not add reason.?

Question

You remember E=mc2.But he said mass increased with velocity.
That is not correct - the potential energy increases, The energy, not the mass, the mass will always be the same but weigh differently according to the ambient gravity.

Answer 1

Well, you have to remember the statement of E=mc^2 is related to his Theory of Special Relativity. So E=mc^2 is relative, and it depends on your referential frame. So if you were moving at 99.9999999% of the speed of light, and you measure your mass, you'll find that your mass is the same. But to someone else who is on Earth, when he measures your mass, he'll find that your mass has increased. And how much increase in mass depends on your speed. So Einstein is right.

Also, your statement that potential energy increases is incorrect. It is the "Total Energy" that increases.

Answer 2

Seriously Alan - this is the most famous equation in history from the most brilliant mind the world has ever known, and you're wondering if he was RIGHT? I think if he'd been wrong, we'd have heard about it by now.

E=MC 2 simply tells us that mass and energy have an equivalency, are two aspects of the same thing - and the faster an object travels, the more of it's mass it needs to convert in order to keep going - until, at the speed of light, it's requirements become infinite. Which is why nothing can go faster than that.

Answer 3

E=mc2 is just one of Einsteins equations, albeit the most famous as it is the simplest one. It gives the ammount of energy contained within a specific mass, mass and energy being interchangeable.

The rest of the maths in relativity are complex, as can be seen here http://en.wikipedia.org/wiki/General_relativity.

Basically the mass does change at faster speeds relative to the observer. I think gravity is also connected to mass, the more massive something the more gravity it has

Answer 4

With all due respect its interesting that someone with obvious limited knowledge of physics could hear of some of Einstein's predictions and imagine that arguaby the worlds greatest scientist was wrong.

It IS correct - mass does increase with velocity - except the effect is negligible at speeds that are not approaching c. The energy increase (potential energy is provided by say, rolling a boulder up a hill).

With all due respect you need to look at what Einstein actually said. I recommend Brian Green's Fabric of Reality or if your mathematics are up to it you might enjoy 'Subtle is the Lord' which is a technical biography.

Answer 5

The idea of mass increasing with velocity comes from special relativity, and the idea that nothing can go faster than the speed of light in a vacuum.

Basically, as a body approaches the speed of light, it becomes more difficult to accelerate - otherwise, it could go straight through light-speed and out the other side. Newton tells us force = mass x acceleration, so if acceleration is reduced for a given force, it must be because mass has increased.

Einstein tells us that, in effect, kinetic energy is "stored" in the form of mass. But note (second reference below) that this is only APPARENT mass in a given frame of reference - in the object's own frame of reference it appears to have its resting or "invariant" mass.

Weight is an entirely separate concept which, as you say, depends on the strength of the local gravitational field. It is properly measured as a force (ie measured in Newtons), even though we commonly express it in units of mass (kilograms).

Answer 6

Yes, Einstein was right for theorizing that as mass acheive the speed of light, it will become Usable energy ( hence, fusion and fission) ... anyway, lets talk a lil about this idea... as you can tell, your mass are invariant regardless of speed... if u go 40 miles per hour, ur mass = the same... (fat people rarely move.. lol jk) anyway, u miss the ideal problem in E = mc^2 ... there is an invisible variable there... it is called m(o) , indicating rest mass.... and as you acheive the Speed of light for that Object, the energy also acheive infinity... meaning that, it takes infinite amount of energy to accelerate an object to the speed of infinity (theoretically impossible).. so, as u can see, that equation is pretty much theoretical (all physics are)..

Answer 7

it as been found that when particles are accelerated at close to light speed last longer then in a normal state E=mc2 works.its good to know that somebody out there are doing what Einstein once said its far better daydreaming of possibilities and i think that the grey matter within your head may well come up with another theory you may be correct but you need to Analise all the possibilities the art of thinking is what if!,what if i did this and what would be the outcome. i at present have clear view of a problem i will need to deal with thinking about it will not solve my problem i just need to get on my hands and knees and pick the toys up that my grandchild decided to leave on the floor that's visible but out there its invisible and the greatest place to be .USE YOUR BRAIN.

Answer 8

The mass DOES increase with velocity, for an external observer.
One can then consider that kinetic energy is entirely contained in the increase of the mass.
Einstein WAS right.

Answer 9

Einstein was wrong in his conclusion. He supposed that, because mass and energy are equatable, that the addition of movement was equal to that of energy - it isn't. When a mass accelerates, what happens is the frequency within the moving mass changes potential. It changes from existing as right angle potential to direction of movement to that of existing in direction of movement. http://timebones.blogspot.com and

Answer 10

You know more than Einstein ? No, the energy does NOT increase ! Your post makes no sense at all. "Ambient gravity" ? In outerspace ?
