Question time!!!!


Q1. Why does the world seem stationary when we travel at the speed of light?

Q2. A super-train travels at 60 percent of the speed of light relative to you on your bench. Due to the extreme comfort of the bench, you accidentally doze off. Eventually, you wake up and determine that you napped for 4 hours! How long would a train observer measure your nap to be?

Q.3 Why does the Earth revolve around the Sun?

Thats it 4 now

Answer 1

A1. The world would seem stationary as you travel at c because as you travel at c the light coming from objects around you will never catch up to you as your relative speed becomes 0.


Answer 2

Well, using the time dilation formula, here we have t0 = 4 hrs and v = 0.6c, so v/ c = 0.6. Therefore, a train observer measures your nap to last. Substitute the values and use the formula and you'll get 5hrs.


Answer 3

The earth does not revolve around the sun because the sun is has a force called gravity but revolves because the gravity of the space pushes the earth towards the sun.

The Equation of special relativity This is a little complicated though not that difficult if you are curious to know about the theories of Einstein. So this all started of an imaginary clock known as the light clock. This consists of two mirrors placed parallel mirrors.  A beam of light is shined and keeps on going up and down as shown in scenario 1. Now for example your friend 'a' is holding the light clock in the dark in front of you 'b'. Lets take the legnth between the two mirrors as 1 m. Thus the time take for the light to go from the 1st mirror to the 2nd is = 1/300000000= 3.3 nanoseconds. Let us draw this in the form of a triangle. So side b is 3.3cm(.now it is going to become a little complicated) But if 'b' starts moving with the light clock at half the speed of light. the light forms a zig-zag pattern as shown in scenario 2. Now 'b' is running at half the speed of light so his path will also be half the time taken by light while movi

Blackout Pointer Theory

Blackout Pointer Theory The Blackout Pointer  Theory was a theory given by Aarav Rawal in 2017. It is derived from the Special Theory of Relativity of Einstein. It is a part of relativistic mechanics. Its main objective is to theoretically prove the working of a time machine. A time machine can take you into the past or the future although this theory explains only how it can take you behind in time. In Einsteins Special theory of Relativity, albert says that if you travel at the speed of light then time will be equal to zero because the light coming from your surroundings will not be able to catchup to you. This can be mathematically proved: {\displaystyle Vrel=c-v} {\displaystyle v=c\therefore } {\displaystyle Vrel=0} {\displaystyle \because t={d \over Vrel}\therefore t={d \over 0}=0} If time becomes zero then everything around would seem stationary. Blackout Pointer Theory Lets take an example that includes the time dilation formula. Lets say you sleep f
