This concept is known as time dilation. The birth of the concept of time dilation dates back a little before the twentieth century, during the late ninetieth century. But Albert Einstein’s special theory of relativity established it and it became popular. This theory had a concept, velocity of light in a vacuum is constant throughout the ...
The relative nature of time means that the clock slows down if our speed increases, a phenomenon called time dilation. So, if we accelerate to speed 90% of the speed of light for 160 days according to our clock, we would have passed 365 earth days. This is because the clock at Earth is almost stationary and it does not show any time dilation.
Time dilation means the discrepancy that arises between time measured by two observers when one is stationary and other is traveling at high speed (or one is in smaller gravitational field and other is in greater gravitational field). Whereas, time traveling means traveling to events which have already happened or which has not yet happened.
(time dilation/length contraction) The variable form of time introduced the concept of negative time (past) and positive time (future). Finally, time became the fourth dimension including the other three spatial dimensions (along length, breadth, and height in a rectangular coordinate) used to define the position of a matter in the spacetime ...
5 Extraordinary Things That Happens Inside The Black Hole. 1. Time Freezes – No Past or Present or Future. Ever since the theory of relativity was published, the concept of time has changed. Time does not pass uniformly everywhere. According to gravitational time dilation, strong gravitational fields set up by massive objects in the universe ...
So, during some time of the year, it is closest to the Sun whereas it lies farthest some other time. The plane of the Sun’s path in the sky (called the ecliptic), which is coplanar with Earth’s plane of revolution around the Sun is tilted with respect to the equatorial plane of Earth. This angle of tilt is about 23.5 degrees. This is the ...
Perpetual motion machine and its possibility. Unlike perpetual motion, a perpetual motion machine is something from which we can generate work without its motion being halted till eternity as stated earlier. If we were to invent such machine we would violate the laws of thermodynamics. According to the law of thermodynamics, if work is done ...
For the one speeding nearly at the speed of light, this effect becomes more significant. The squared ratio of velocity of the object to the velocity of light in vacuum determines the extent of this effect to be observable. This means that the velocity should be nearly equal to light to make a vast difference in length, mass and time.
Though graphite, its bulk form is brittle, it is 200 times stronger than steel. So, it can enhance the toughness of a material. This property has made it a promising material for use in vehicle parts, shoes and other tools. It is likely to enhance the polymers that are being used in modern times. In modern times, polymers are widely used.
The Ultimate Source of Energy. Nuclear fusion occurs deep into the core of our local star (yes, the sun is a star–a BIG star!). They generate a tremendous quantity of energy that travels at the speed of light (more than 186,000 miles per second). That energy travels 93 million miles to earth in under eight minutes.
