Break the Universe · Printable worksheet

Change one thing

Compare two universes. Keep every dial except Λ fixed, and write evidence before a conclusion.

Name / group:  

Class / period:  

1 · Prediction and reason

If Λ increases while the other eight dials stay fixed, I predict… because…

2 · Observed model outcome

Test · Λ = 80× ours2dwf5gulpfzgontdw3Launch in classroom mode

3 · Evidence from the runClaim

  1. 1.Which variable was independent? Which outcome was dependent?

  2. 2.What evidence supports your claim?

  3. 3.What can this experiment not tell us about the real universe?

Exit ticket

In one sentence: changing Λ caused ___ in the model because ___.

The Λ threshold is an authored, Weinberg-style toy rule coupled to structure amplitude. The animation is an explanatory encoding, not a numerical cosmology simulation.

Teacher key: expected outcomes are model outputs, not observations of real alternate universes.
