How does our limited perception affect our understanding of the universe?

Our limited perception, influenced by our narrow optics and the quantum world, makes it difficult for us to understand and reason about the world around us.

What advancements have been made in understanding the universe through telescopes and satellites?

Through radio telescopes and satellites, we have made significant discoveries about the transparent atmosphere, the electromagnetic spectrum, and the history of the universe, leading to the need for improvement in our physical theories and the possibility of using gravitational waves to gather information about the pre-Big Bang era.

How can neural networks be used to broaden one's horizons?

Neural networks can be used to translate videos and broaden one's horizons by allowing them to watch foreign content in their native language.

What is the concept of time in the quantum world?

In the quantum world, there is a problem in understanding and discussing time in the same way as the classical world.

How does the theory of relativity explain time?

The theory of relativity explains that time is relative and different observers have different views of the same events, with the universe continuing on but with no single picture or order of causal events.

TLDR Advancements in technology and theories offer new possibilities for exploring and understanding the complexities of the universe, including concepts like time, quantum physics, and the need for a comprehensive theory.

The Nature of Time and Space

🌌

Exploring space directly helps in understanding how the world works and provides food for thought in unraveling the mysteries of the universe.
📦

The concept of empty space as an abstract entity, separate from fields or bodies, challenges classical intuition and contributes to a deeper understanding of the nature of space.
🌌

Special theory of relativity challenges the concept of absolute time and space, suggesting that they are not separate but rather intertwined in the concept of spacetime.
🌌

The concept of time may be different in different parts of the universe, with the possibility of time ending in certain situations like falling into a black hole.
🔄

The irreversible nature of the world is highlighted, using the example of a broken cup and the expectation that the pieces will not gather again.
🔄

In the micro world, time is reversible, but in our world, irreversible effects occur, creating a clear distinction between the two.
🌌

Entanglement occurs when there are a large number of interactions, leading to confusion and the enhancement of states in a device, which has implications for our understanding of space and probability.
🧩

The complexity of the world and our interaction with it is a long-standing question that may never be fully answered, as we strive for a deeper understanding of our existence and the underlying equations that govern it.

Entropy and the Arrow of Time

🌈

Gravitational waves could provide valuable information about what happened before the big bang, potentially serving as a check on the theory of inflation.
🌌

If the original state of the Universe had low entropy, we wouldn't have memories of the past and wouldn't see the Arrows of time.
⏳

The existence of memory of the past and not the future is related to the low entropy states at the start, highlighting the connection between entropy and the direction of time.
🔄

The arrow of time and the feeling of time passing is closely related to the existence of a low entropy state at the beginning of the universe, although there are different theories explaining its origin.
