How have Einstein's theories of relativity changed the world?

I have:


* Time dilation has led to the development of satellites.


* E=mc虏 -%26gt; foundation to the development of atomic energy.


* led to the Manhattan project and first atomic Bomb which has changed history.





I don't know if E=mc虏 is part of Einstein's theories though..


also how else have his theories of relativity changed the world? has it changed how we view the Universe was formed?|||okay... E=mc^2 is part of special relativity, for sure, but was originally published in an almost forgotten article... it is more properly stated as E = p^2m^4 + m^2c^4. e=mc^2 only refers to the rest energy of mass, and does not take into account if the particle is moving (e.g., if it has kinetic energy). The equation I gave above is the full version.. p=momentum, and takes into account ALL particles, motionless or in motion.





Time dilation did not lead to the development of satellites.... it helps in synchronizing them.





Relativity first helped explain PRECESSION (of Mercury), which you probably could say has helped us in looking for extra-solar planets.





Yes, E=mc^2 did lead, via Roosevelt, to atomic energy (the Manhattan project, etc).





I would focus more on particle physics if you want to go further. If (like with the LHC -- large hadron collider) we accelerate particles with a small mass to nearly the speed of light, then they take on more mass and more energy. Einstein's theory has lead to discovery of new elements in the periodic table. It has provided a fundamental basis for a lot of the things in quantum mechanical theory,. even though quantum mechanics, as of now, does not work with relativity.





BLACK HOLES -- as the center of each galaxy -- is all Einstein.





Some stars periodically shine light on us brighter than entire galaxies... determining what those were is all Einstein... neutron stars (half-dead stars that originally had more mass than the sun but not enough to become a black hole).





Astronauts in space have to use a special clock... for many purposes, if your clock is off by .01%, then it doesn't matter. Re-entry into the atmosphere... then it does matter. Going nearly 30 k/hr orbiting the earth does make clock run slower compared to an observer on earth... so relativity definitely contributed to the space program.





The original theory of general relativity contained a "cosmological" constant that as supposed to make the universe static (unchanging). His original calculations showed that the universe should be expanding. Edwin Hubble proved that the universe WAS INDEED expanding, and Einstein removed the cosmological constant, calling it the biggest blunder of his life.





Today, though, the idea of a cosmological constant is still thought about.. embraced. Amazingly, it has something to do, sometimes, with quantum mechanical effects.





I could go on forever, but relativity definitely changed everything.
