String Theory Notes (Part 1) & Questions

• Investigate blackhole
• Shortshield found that huge energy compacted into dot = black hole
• Center: tiny+heavy
o Use quantum general relativity
• String – everything in the universe as strings, vibrating
• String theory – can’t test, so it is not science, its philosophy
Two Sets of Rules
• Quantum mechanics – atoms (web of space chaotic, twisted, unpredictable)
• Theory of relativity – planets (web of space predictable, smooth)
• Set two theories together; breakdown, they conflict
• Scientists are not trying to combine everything

• Gravity, electromagnetism, quantum theory, radioactivity can explain the birth of a star
• Young physicist 1968 found accidentally an equation that explained string theory (this is the birth of string theory)
• Messenger particles (in between) drag things together
Electromagnetism + Weak force + Quantum Mechanics meld together when universe started
String Theory – particle of gravity (graviton)
Maseless particle
Anomalies in theory
• Solved by Michael Greene – made lecture called “Theory of Everything”
• Electron made of corks
• Corks made of strings
• Strings are so small, it is like the atom is the size of the universe and the strings is the size of a tree
• Strings vibrate differently
o Thus allowing different masses, properties
String Theory makes Quantum Theory Calm
• But this needs to be proved
• Universe may have 4 dimensions
o Perhaps a tiny tiny dimension smaller than atoms
• String theory proposes 6 other dimensions
• Dimensions are twisted and curled
• These dimentions control the way the string moves
• Strings may have open strands, causing 6 dimentions
o Which one is ours?
Five Unanswered Questions that I Thought Of
Is there a unified equation to unite the 3 forces of the universe?
How would you be able to experiment with string theory?
Are there really 11 alternate dimensions?
If so, which one is ours?
Is there even a theory of everything?
Questions I need to Answer:
What is the difference between theory and philosophy?
Theory is when a scientific concept is widely accepted to explain a phenomena, but cannot be proven
Philosophy is a set of individual belief that influence they way they live their life and the way they look at others.
When does a theory become a fact?
A theory becomes a fact when it has been tested and proven.
When will string theory become a religion?
String theory will become a religion if it doesn’t get proven for a long time.
