I want to know whether theory of relativity is applicable to today's life?

Question

if it is theoritically proved find me it's applications in today's life.

Answer 1

There are many uses for relativity, how about the following...

from Astronomy it is possible to tell if an object is moving towards or away from us and how fast it is moving

from Physics it is used in experiments to understand the behaviour of elementary particles travelling close to the speed of light as they collide

from Engineering it is a factor in the Global Positioning System[1]

Answer 2

Well, you've gotten some BASIC answers, but none which truly capture the nature of relativity. They're all too specific...

YOU ARE A PART OF THE THEORY OF RELATIVITY. You're what is called an observation frame. That is, you observe things from your point of view. At the very core of the theory of relativity is the statement: "Perception of events varies between different frame of observation." Essentially, every time you sense ANYTHING you're taking part in the theory of relativity.

Further, relativity does NOT go on top of Newtons laws. Integrated across the total of the relativistic particles, relativity IS Newton's Laws in a shiny, new, more accurate form. All motion and interaction of forces is therefore relativistic, but you don't see it because most systems are so large they behave in the way that classical physics predicted.

I think Einstein himself said it best when he stated: "Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity."

Answer 3

Yeah lots! While it's true that most of the world we see around us conforms to old Newtonian physics, relativity is also present. For example, if you have ever worried about the possibility of nuclear destruction, you should also think about the fact that atomic and nuclear weapons are a direct result of the general theory of relativity. Einstein's theory of relativity led to the creation of incredibly powerful nuclear weapons, the destructive capabilities of which have changed the face of world politics. But it also gave us nuclear power, which now accounts for a fifth of all the world's electricity.

Answer 4

I do not whether you want to disprove Albert Einstein or want to know something about theory of relativity.

If you are travelling in a train, and come across another train which is travelling with the same speed, both the trains seem stationary. Do they not?

Answer 5

E = mc^2, although very useful for us today, has practically nothing to do with Einstein's theory of relativity. It is more of a derivation from his ideas on relativity.

In modern life, relativity is hardly seen, and in the average persons daily life, relativity plays no direct role. Indirectly, however, relativity does seem to pop up. For example, most satelites orbiting earth have to have a precise clock. At the speeds that these satelites are moving, relativistic effects are tiny, but over time starts to be noticable, to a scale of microseconds, and given long enough time, even seconds. Though this doesn't sound like much, for the precise interaction between earth and satelites, this tiny effect has to be compensated. So for daily life, communication is affected by relativity.

Then of course relativity is extremely important in experiments with high speed particle accelerators and colliders, like CERN. In modern life there is at the moment not much direct use, but in the future particle acceleration can become the basis behind all of our energy source, in nuclear fusion.

Not that this is an application, but it is interesting to know that relativity is all around us, even though we dont see it. Certain elementary particles (muons) that get created in one of the highest sphere's of earths atmosphere has an unbelievably short lifetime, making it classicly impossible to appear on earth's surface. However, at the speed that they travel, relativistic effects allow these particles to live longer, and are bombarding us as we speak.

So, long story short, inderectly, relativity is important to today's life. But directly for our lives, we don't have to worry about such things as slowing down our clocks while flying in airplanes.

Answer 6

Einstein's theory of relativity including E = mc2 permits the sun to shine for billions of years while converting hydrogen to helium. Helium is even named after the sun! Also without the theory of relativity that bends space due to the gravitational mass of objects, the earth would fly off into space rather than orbit the sun and we would all freeze to death. Of course, without relativity we would not even exist and that affects everyday life.

Answer 7

You encounter relativity every single day. Magnetism is the result of a relativistic correction to the motion of electons in a conductor - there is no such thing as a fundamental magnetic force. And magnetism is used to generate electricity, run motors etc.

Answer 8

there aren't many. it's a theory that deals with things separated by vast distances or travelling at astounding speeds.
