What If Space And Time Are NOT Real?

The video explores the evolution of the concepts of space and time in physics, from ancient ideas to modern theories. It discusses the views of key figures like Newton, Leibniz, and Einstein, and how their theories shaped our understanding of space-time. The video also touches on current challenges in physics, such as the conflict between general relativity and quantum mechanics, and the potential need to rethink our understanding of dimensions.

What is the primary challenge in understanding space and time according to the introduction?

• They are only relevant in theoretical physics.

• They are intuitive but may not be fundamental.

• They are not related to each other.

• They are too complex to study.

How did ancient philosophers view space?

• As a network of relationships.

• As a non-existent concept.

• As a mathematical abstraction.

• As an absolute entity.

What was the significance of the Cartesian coordinate system?

• It was used to disprove ancient geometries.

• It was the first system to measure time.

• It allowed for the mapping of abstract concepts in space.

• It proved the existence of empty space.

What was Newton's view on space?

• Space is only a mathematical tool.

• Space is a relational concept.

• Space does not exist.

• Space is an absolute entity.

How did Leibniz's view of space differ from Newton's?

• He thought space was a relational concept.

• He believed space was an absolute entity.

• He denied the existence of space.

• He believed space was a mathematical abstraction.

What did Einstein's theory of relativity change about our understanding of space and time?

• It separated space and time into distinct entities.

• It combined space and time into a single continuum.

• It proved space is an absolute entity.

• It eliminated the concept of time.

How does Einstein's view of space differ from Newton's?

• Einstein believed in an absolute space.

• Einstein thought space was a mathematical abstraction.

• Einstein denied the existence of space.

• Einstein saw space as a dynamic field.

What is one of the major challenges in modern physics regarding space and time?

• The lack of mathematical tools to study them.

• The conflict between general relativity and quantum mechanics.

• The lack of interest in their study.

• The inability to measure them accurately.

What does the concept of 'vacuum energy' suggest about space?

• Space is an absolute entity.

• Space is a mathematical abstraction.

• Space has intrinsic energy even without particles.

• Space is completely empty.

What is a potential implication of emerging theories like string theory and loop quantum gravity?

• Space and time are absolute entities.

• Space and time are purely mathematical constructs.

• Space and time may emerge from more fundamental elements.

• Space and time are irrelevant in modern physics.
