Do you ever get the feeling that time is just dragging on? You might be working in the office, sitting at your desk at school during a long lecture or waiting for the doctor to see you, but when you look up at the clock, you could swear the 15 minutes it took for the long hand to move a quarter of an hour were really twice as long. No matter how much you squirm and fidget, time is taking its sweet time in getting to the future. On the other hand, sometimes it can feel like time moves too quickly. Deep, engaging conversations with friends and loved ones can last for several hours but make you feel like time swept by in minutes. You can wake up right when the alarm goes off in the morning but somehow still end up running late for work. You're left throwing your hands up, wondering what happened to all of that lost time.

Does time really change its speed depend on the situation or it is just a feeling? Do we only feel that time is lasting longer than usual or actually it is? There are several theories which describing how time changes and how can we make up with it. You may have heard from elders in your family that a day in Heaven is equal to 100 years on earth or something like this. Is it true? Ok, lets find out the truth behind it...

I am presenting two theories "Time Dilation" and "Twin Paradox" from Einstein and Paul Langevin respectively.

Time Dilation: You must have known to the Einstein's theory of relativity, where he associate time with space and call it space-time. Einstein suggested that space-time wasn't flat, but curved or "warped" by the existence of matter and energy. Large bodies in space-time, like the Earth, aren't just floating in orbit. Instead, imagine an apple resting on a stretched out blanket -- the weight of the apple warps the sheet. If the Earth is an apple, then we can imagine the Earth's blanket as space-time.

This means that someone moving through space-time will experience it differently at various points. Time will actually appear to move slower near massive objects, because space-time is warped by the weight. These predictions have actually been proven. In 1962, scientists placed two atomic clocks at the bottom and top of a water tower. The clock at the bottom, the one closer to the massive center of the Earth, was running slower than the clock at the top.

Twin Paradox: A further explanation of the bending of space-time and time dilation came in the form of a thought experiment called the twin paradox, devised in 1911 by French physicist Paul Langevin. If one twin lives at the foot of a mountain and the other lives at the top, the twin closer to the Earth will age more slowly. He or she would turn out younger than the other twin, though by a very small amount. If you sent one twin in a spaceship accelerating close to the speed of light, however, he or she would return much younger than the other twin, because high acceleration and large gravitational masses are the same in relativity. Of course, no one's gone so far as to send somebody's twin into high-speed orbit, but scientists proved the hypothesis true in the '70s by sending an atomic clock into orbit. It returned to Earth having run much slower than grounded atomic clocks.

So here it confirms that at high altitudes time passes slower than it does near earth. Since Heaven is supposed to be at very high altitudes so it can be said that time doesn't pass at the same speed there but much slower than on earth. So it is confirmed that a day in Heaven is equal to 100 years on earth. :) So now onwards, whenever you're late for work or want the weekends to last longer, make sure you stay close to the ground and accelerate as much as possible. Boring lectures and waiting areas in doctor's offices, on the other hand, should be spent in the topmost room of high towers.
