Abstract

The theory of Entropic Gravity and Emergent Spacetime offers a new way to think about gravity and how space and time work. This study explores the idea that gravity comes from changes in information on surfaces and that space and time might not be basic things, but instead come from tiny building blocks. The research has two main goals: first, to explain Entropic Gravity, which says gravity happens because of changes in information on surfaces; and second, to talk about Emergent Spacetime, which suggests that space and gravity aren't basic, but come from small things we can't see. By looking at what other scientists have written, we study the basics of Entropic Gravity. We talk a lot about the holographic principle and how gravity might be a kind of force that happens because of information changes. We also study Emergent Spacetime ideas, which come from holography and dual descriptions. These ideas help us learn more about things like black holes, dark matter, and how information and shapes are connected. Our presentation show that Entropic Gravity could explain things we usually think are because of dark matter and dark energy. It could also help us understand more about black holes and fix a problem called the black hole information paradox. We also show that ideas about Emergent Spacetime help connect two big theories, quantum mechanics and general relativity. This means that the way things move on a really small scale and the way big things like planets move might be linked.

We make things clearer by including a picture that shows how information is put on a surface and a table that compares regular gravity with the new idea. To finish, this study makes our understanding of gravity and spacetime better. It says that maybe gravity comes from a force we didn't think about before, and that space and time might be made from smaller things we can't see. The ideas of Entropic Gravity and Emergent Spacetime could help answer big questions in physics and change how we think about the universe.
