THE UNIVERSE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During science class, when we were discussing about the universe expansion, we talked about TIME. Why do we say that time is relative? Choose the option that best answers the question.
A
Time is not relative because, Time does not exist it is an illusion. It is not measurable.
B
Time is relative because it depends on the observer. For example, if the observer is having a good moment, time flies; but if the observer is nod having a good moment, time passes slowly.
C
Time depends on the space and quantum physics. If the observer is looking at the hour it goes slowly.
D
None of the above
Explanation: 

Detailed explanation-1: -Put simply, special relativity tells us that moving clocks run slowly. This is a phenomenon called time dilation, and it’s a cold, hard fact of the universe. Einstein had to introduce the concept to rescue something he thought was much more fundamental: the universality of physical laws.

Detailed explanation-2: -May 1905: Lightning Strikes a Moving Train Einstein’s revelation was that observers in relative motion experience time differently: it’s perfectly possible for two events to happen simultaneously from the perspective of one observer, yet happen at different times from the perspective of the other.

Detailed explanation-3: -Relativity tells us that the same laws of nature hold true everywhere in the universe. This equivalence principle also confirms that two bodies fall through a gravitational field at the same rate regardless of their mass. All of which brings us to Einstein’s talk at the Prussian Academy.
