Good points!

Also, regarding time- Entropy is one of the few quantities in the physical sciences that require a particular direction for time, usually called an arrow of time. As you will know one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. Thus, entropy measurement is a way of distinguishing the past from the future.

We can go further and say that there are three main arrows of time. They are:

(i) Thermodynamic arrow of time

(ii) Psychological arrow of time

(iii) Cosmological arrow of time

Furthermore Time Dilation and Length Contraction in Special Relativity demonstrates speeds greater than 0.5C affecting time and space. Although time is not a literal dimension it is affected dramatically- For example see http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/muon.html and

I am just being pedantic and want to join in the conversation with the big boys. Just correct my errors in thinking if I am way off the mark please.

Kind Regards,
