What is wrong in the graph
Answers
In the given graph, time is negative, which is not possible.
In the graph, time can be seen in both positive and negative x-axis, but time can only be positive, thus time can only be drawn in positive axis.
Why time can not be negative?
→ Negative time means we can go backwards in time, which means we are actually time travelling, which is not possible yet. Hence, we consider that time is always positive.
Answer:
Becoming zero twice and negative time.
Explanation:
In this graph, we can see that time is on X-axis and on y-axis nothing is written.
So, the problem must be with X-axis. Now we know see that time always move constantly. It's uniform, it doesn't accelerate or becomes zero.
But in the graph after starting point i.e, origin it is again becoming zero twice. Which is physically impossible.
Moreover, time can't be negative which is actually shown in the graph. As curve of time is below x- axis, it's showing negative time.
