INSIGHT

De Sitter vs. Anti-de Sitter Space

  • We live in de Sitter space, which is exponentially expanding and unlike anti-de Sitter space.
  • Anti-de Sitter space has a boundary crucial for holographic descriptions, but de Sitter space has no such boundary.
ADVICE

Explore de Sitter space

  • Young physicists should be encouraged to explore de Sitter space.
  • This area offers new possibilities, unlike well-trodden areas where much has already been discovered.
INSIGHT

String Theory Is Not Reality (Yet)

  • Precise string theory (String Theory with capital "S") is not the real world.
  • It needs to be generalized and expanded because it relies on features like supersymmetry not present in our universe.
