Big Rip is unlocked when buying the relevant mastery study. You will need 2e98 time theorems and the "The Challenging Day" achievement. In Big Rips, everything except normal dimensions and post-quantum mechanics is disabled. You are also stuck in PC6+8. When you exit Big Rip, you gain Space Shards based on your best antimatter while in Big Rip (log10(AM)/200, 1.5 * ( DT + 1 ^ 0.05). There are 20 upgrades you can buy that cost Space Shards and some of them disable others.
