It seems to be a weird question that "Is this world real?" Why it seems to be too real? Because we see it, isn't it? We see things exist and happen as time flows. Besides seeing, we also hear, touch, smell and taste to realize our surroundings. Thus, we say "there it is" or "that is happening". Think if you had no eye, nose, ear, tongue or feeling of touch or pain; then, you would be very helpless. Why? Because you would not be able to sense anything then. Surprisingly, you won't be able to say how the world around you is. You have to have those parts of your body to realize the truth or experience the reality. Now, what are the functions of those parts? Simply they are sensitive to stimuli (such as light, smell, sound etc.) and those stimuli make nerve impulses that are carried by sensory nerves to your brain. In conclusion, what your brain experiences make an image of 'reality' and you simply believe that without confusion. ...
Albert Einstein once said that the thing he found which made him the happiest is seeing a man falling from a roof. What made him so happy about this though? He actually made a law of equivalency between gravity and acceleration. According to him, gravity is nothing but an illusion. Think you are in a rocket in space. The rocket is moving with uniform velocity. In accordance with your surrounding you are not moving, just floating still inside the rocket. You may have some things like a bottle, paper, helmet, screw etc. You will see them also at rest. If you hit them slightly they will start moving in that direction with uniform speed. But, if one observes this system from outside the rocket he will find that all these things and you are going with a uniform speed along with the rocket. So motion is relative. Now, think, a person was painting a roof of a very very high building(say it was Burj khalifa). Suddenly, he slips and started falling d...
