Okay, now I know something like this may seem improbable.
But what would happen if Einstein's theory of E=mc2 was wrong?

.euphoria said:Okay, Let's say we could accelerate towards c without our mass becoming infinite. Would this have implications on the laws of physics as we know it?
This is like asking what would happen if we discover that we've been wrong all this time to think that stuff we drop fall towards the ground, and that they actually just float at a constant distance from the ground..euphoria said:But what would happen if Einstein's theory of E=mc2 was wrong?
OK, it makes sense to ask what would it would mean if special relativity makes bad predictions about massive objects that have been accelerated to speeds extremely close to c. It would mean that both special and general relativity would have to be replaced by more accurate theories (but we already know that they need to be replaced, because SR can't handle gravity and GR can't handle quantum effects)..euphoria said:Okay, Let's say we could accelerate towards c without our mass becoming infinite.

If relativity didn't say what it says, it wouldn't be relativity, would it? Are you asking us to use another theory to answer the question? Which theory would you like us to use?.euphoria said:What would happen to the concept of time if one could pass light speed? Would time dilation still happen at speeds greater than c or is it limited to below light speeds?

arkajad said:But is it true? For photons, for instance, m=0, but E>0.
Hyperspace2 said:Yes photon has mass and it depends upon wavelength.
arkajad said:Wasn't E=mc^2 sufficiently addressed in many threads?
arkajad said:I agree, but I thought wouldn't it be better to replace the potentially misleading, unless taken in a proper context, E=mc^2 formula with a rigorous and clear

Don't confuse what the OP asked with the mistake that Hyperspace2 made. We don't know yet if the OP either knows about the full equation, or if the question is really specific that to the mass-energy relation. Often, threads like this are made worse by responses that assume way too much and cover too broad of an area.

Hyperspace2 said:Evidences
eeinstein says mass and energy are equivalent.
Light is deflected by gravity. etc etc
ZapperZ said:You really need to read the FAQ. You are making a horrible misinterpretation. That's like saying a tomato has dirt, just because it grew out of the ground.

What would happen if known physics were wrong? It would be wrong. GPS devices would retroactively not work; people who thought they'd driven safely to work this morning will discover they have in fact driven into a lake..euphoria said:I'm not asking for you to create a new theory all together. I'm just curious as to what would happen to pretty much everything we know about relitivistic physics? Assuming that E=mc^2 was wrong?
So what theory are you asking me to use?.euphoria said:I'm not asking for you to create a new theory all together. I'm just curious as to what would happen to pretty much everything we know about relitivistic physics? Assuming that E=mc^2 was wrong?
Einstein's theory of relativity is a scientific theory that explains the relationship between space and time, as well as the concept of gravity. It consists of two main theories: the special theory of relativity, which deals with objects moving at a constant speed, and the general theory of relativity, which includes the effects of gravity on space and time.
E=mc2 is an equation from Einstein's theory of relativity that shows the relationship between mass (m) and energy (E). It states that energy is equal to the mass of an object (m) multiplied by the speed of light squared (c2).
E=mc2 is used in everyday life in various ways, such as in nuclear power plants, where energy is generated through the conversion of mass into energy. It is also used in medical imaging technologies, such as PET scans, which use the equation to convert the energy emitted by radioactive substances into images of the body's internal structures.
If E=mc2 was wrong, it would have significant implications for our understanding of the universe. It would mean that our current theories and equations regarding energy and mass are incorrect, and we would need to come up with new theories to explain the relationship between the two. However, the equation has been extensively tested and has been proven to be accurate, so it is highly unlikely that it is wrong.
Einstein's theory of relativity has had a significant impact on science and technology. It has led to the development of new technologies, such as GPS systems, which use the theory's principles to accurately calculate and adjust for time dilation caused by the Earth's gravitational field. It has also advanced our understanding of the universe, leading to breakthroughs in astrophysics and cosmology.
