During the final battle, Kala sucks in the universe in order to consume Ajna, but Ajna breaks free. How can I be sure it's the universe? Foremost, Kala is the creator and destroyer of the universe, and has done this repeatedly.
5:38, Ajna enters the area Kala is, and the final battle begins.
26:53, we see the location of the place the final battle took place in relation to the planet. In the background we see stars and nebulas. Where this just the arena, the stars in the background would still be visible.
Nowhere in the world is safe from Kala, and she can reset the world as many times as she needs too. Infact, in order to escape Kala to figure out a plan, they enter Ajna's Inner Realm, as that's another world.

So given that context of Kala destroying the world to create it anew (contextually a universe), Kala being able to reset the world (from out in space), needing to escape to the dimension in Ajna's brain to avoid getting caught in the world being reset and Kala leaving a black void when there should still be stars clearly visible, in context she's sucking up everything, but Ajna escapes and it's restored.
The radius of the observable universe is 46 billion lightyears (or 46,000,000,000 lightyears).
Timeframe is 28 frames. For some reason, we're back to 30 frames again.
T = 1s/30
= 33.3333333ms X 29
= 0.966666666s
T = 46000000000LY/0.966666666s
= 4.50190662e26/299792458

Final Results
Kala sucks up the world = 1501674410000000000 C
