  • Lawrence Krauss changed his position on vacuum energy after data contradicted theoretical expectation.
  • He emphasizes science's strength is adapting when evidence forces revision.
ANECDOTE

Skepticism About The Higgs

  • Krauss recounts he once didn't believe the Higgs boson existed and even worked on alternatives.
  • He later accepted the Higgs after experimental evidence validated it.
INSIGHT

DESI Claim Is Overstated

  • Krauss dismisses the recent DESI claim of evolving dark energy as likely a systematic effect.
  • He bets dark energy is indistinguishable from a cosmological constant based on current evidence.
