[Summary and Impressions] "Time Doesn't Exist" A genius physicist cuts through common sense!
//Summary - Level-C2//
In "Time Doesn't Exist," a physicist challenges the conventional understanding of time, arguing that it is a human construct. Time's flow, linked to entropy in thermodynamics, is subjective—entropy measures disorder, increasing over time. The book posits that time and entropy are concepts humans use to interpret change, emphasizing that time's relativity further questions its objective existence.
"Time Doesn't Exist"
1)
It is a book written by a genius physicist that takes a scalpel to the common sense of time.
As Einstein's theory of relativity says, time flows at different speeds depending on the location.
Time is ambiguous and is created by people's perceptions and senses. In other words, it is something that people have arbitrarily decided.
The book denies the existence of the "time" that we take for granted from various perspectives.
2)
Time is created by human consciousness:
Time is thought to flow from the past to the future.
When considering time, the critical word is "entropy," which appears in thermodynamics.
3)
Entropy is "order."
Entropy is expressed as high or low.
Low entropy = orderly. Obeys laws.
High entropy = disordered and chaotic. It's a mess.
The increase of entropy can measure the flow of time.
4)
For example, a glass of water is in an ordered, low-entropy state.
If the glass is knocked over and the water is spilt, it is in a high entropy state.
Or if you pour milk into coffee and the two mix, the entropy changes from low to high.
In other words, the flow of time moves from low entropy to high entropy.
5)
It is said that entropy only moves from low to high. (However, in 2019, entropy reversed, proving that time does.)
And the important thing is that even this entropy is a human perception.
6)
I found an easy-to-understand analogy so that I will quote it here.
Think of playing cards. Arranging playing cards by colour or numerical order is an ordered state with low entropy, while shuffling them is disordered and has high entropy.
"The idea that one arrangement (e.g., 26 red cards followed by 26 black cards) is more special than another only makes sense if you focus on a particular property of the cards (in this case, colour). If you make the finest distinctions among all the cards, then all the arrangements become equal, and none is more special than the others".
7)
I'm trying to say that entropy, representing time's flow, is just a human-defined perception. Sorting by colour and numerical order are also things humans have arbitrarily decided upon.
If you break it down even further, all playing cards are just "cards." Humans invented the concept of arrangement.
Therefore, looking at things from an excellent, microscopic perspective is no different. = time does not exist.
8)
The 19th-century physicist and philosopher Ludwig Boltzmann proved that man invented the concept of low or high entropy to interpret things.
Humans have created entropy, so time is just a concept we have made to understand changes in the world.
9)
Time flows at different speeds in different places:
Did you know that time flows to varying speeds in different places?
This is written in Einstein's theory of relativity.
For example, time passes faster at higher places, such as the top of a mountain, because gravity is weaker there.
10)
Time does not exist:
Time is a matter of human interpretation, and people's memories also create the future and past. There is no uniform time everywhere.
