Time travel for anyone

We went a trip. My wife said I forgot to bring an extra water bottle, then after sometime she said I forgot to bring a knife, yet sometime later she said I should have brought a cup to drink.

Now suppose she had a time machine each time she could have gone back in time and corrected the mistake.

So if we don't make a mistake we don't need to go back to correct it.
Small deviations are necessary for life or life will be so monotonous it will not be worth living.
So if we can live our life to full, we will never need a time machine to time travel to go back.
So live the life to full, don't make mistakes, at least not big ones.

Problem of atomic propositions

Suppose the universe consists of facts.

Each fact can be a thought. Therefore can be represented buy a proposition. And each proposition consists of one or more atomic propositions. Atomic proposition cannot consist two or more propositions, but only one.

Consider inside a room - a room in a house, all the facts inside it are represented by a set of atomic propositions. Consider a proposition about a pedestal lamp is inserted, we can imagine a room without a pedestal lamp now converted to one with a pedestal lamp. Like that facts can be added or removed.

A room is a space. It is a subset of the space of universe. Room should be represented by a single big composite proposition that show every aspect of the room. This proposition will be the conjunction of many atomic prepositions.

The universe is represented by the universal set of all possible atomic propositions.

Any possible proposition is a conjunction of -(set of elements consisting of) atomic propositions.

Then logically the room can be represented by a subset of universal propositions. Wrong! Why?

Consider a proposition that represent Mount Everest. It cannot go into a room. Therefore any subset of the universal set of propositions won't fit a room. We might lead to think it is because of size, but no, Mount Everest cannot be moved to Pacific Ocean. This is an impossibility. Can American Declaration of Independence be inside this room? No. Though the physical size permits, practically it is an impossibility. So factors involved can be unlimited. If it is my room an expensive chair be in the room is illogical. But if the room is of a millionaire it may be possible. But further, a photograph of painting of Mount Everest can be in my room. So not all but some propositions regarding Mount Everest will be acceptable to represent my room.

It means that any subset of the universal set do not represent a subspace of reality.

A subset of the universal set is any number of elements of it taken together.

Room is a subset of universe. But it will not be a subset in respect of conjunction of propositions.

Identifying repetitions is knowledge

Knowledge is finding repetitions in the environment. When the human brain develop from a baby to a grown man it will learn to identify religions. Even the brain is geared to deal with repetitions. More something is repeated more you remember.repetitions is a part of learning of the brain. Knowledge is something only related to a brain. It is true even for animals. Knowledge is used by animals in finding food, sex, survival of the species and other basic needs of life. Regarding humans it has gone beyond the basic needs. Lot of knowledge is utilised in hunting by lions or whales are examples. Maybe hunting is the origination of complicated knowledge. It is more complicated than just eating grass. Carnivores may have developed knowledge over the herbivores.

Each concept created by the human brain is the identification of a new repetition. Creating concepts is a continued process that is never ending, as long as human race exists. And after that artificial intelligence will take over.

If the universe is finite there will be finite number of patterns - repetitions. It will be possible to create a superior pattern from the basic pattern. Then more patterns can be created on these superior patterns. And the process can go on till you create an ultimate pattern. This pattern is ultimate knowledge, the god. W can term it as god sequence.

Finding the generalities, finding the connections is the same as searching for patterns or sequences.
