# Michio Kaku Thinks We’ll Prove The “Theory of Everything” by 2100

## New Physics

A major goal of modern physics is to discover a "theory of everything," a single theory that would explain the physics of the entire universe, everything from dark matter to quantum mechanics.

Theoretical physicist Michio Kaku is one of the scientists [attempting to unearth](<https://futurism.com/why-string-theory-may-be-the-key-to-uncovering-a-theory-of-everything>) this groundbreaking theory, and this week he said he expects scientists will lock it down [by the year 2100](<https://www.reddit.com/r/IAmA/comments/bghqn9/i_am_michio_kaku_physicist_futurist_and_author_of/>) — an exciting prediction that, if proven true, means a new era is physics is mere decades away.

## Mark Your Calendar

On Tuesday, Kaku participated in an "[Ask Me Anything](<https://www.reddit.com/r/IAmA/comments/bghqn9/i_am_michio_kaku_physicist_futurist_and_author_of/>)" discussion. One commenter asked him to share what he thinks will be "the most fascinating thing we might be able to see in our lifetime?"

The physicist's response: "I think in this century (not necessarily in our lifetime)... the 'theory of everything' will be proven."

## Excitement Ahead

That wasn't the noted physicist's only prediction for the 21st century, either. He also told the commenter that he expects we'll establish a brain-net, send a ship to the stars, uncover the genes that control aging, and detect signals from an alien civilization by 2100.

If he's correct, it looks like the next 80-plus years are going to be packed with exciting breakthroughs.
