Understanding the Concept of Infinity in an Exponentially Expanding Universe
1:37:25 - 1:41:10 (03:44)
In an exponentially expanding universe, measuring its size would be impossible as it is always bigger than the distance light can travel. The slices of time also become tilted when observed relatively to the universe.

In an exponentially expanding universe, measuring its size using light would result in infinite space due to the exponential increase in distance remaining to be traversed.

Infinity
Summary
The infinity of the universe can be understood as the inability to measure its finite size through observation or operation. However, it can be viewed differently from a different perspective, such as slice of time, that may result in a finite universe.
