How Will the Universe End?
22:56 - 31:16 (08:20)
To predict how the universe will end, scientists must extrapolate its current state trillions of years into the future. However, the current understanding of the universe is limited, and some theories require retrofitting in order to fit the available data.

The theory of general relativity can explain the evolution of the universe up to a certain point, but it breaks down when it comes to the beginning of the universe.

Summary
The theory of general relativity can explain the evolution of the universe up to a certain point, but it breaks down when it comes to the beginning of the universe. Scientists are trying to modify the equations to attach a different story to the beginning.

The current theories in theoretical physics seem insubstantial and are causing people to retrofit stories to make the theories work, which is problematic as it seems that theoretical physics is bouncing off the limit of a bunch of current theories we have.

By trying to extrapolate the current state of the universe into the future, we're faced with uncertainties such as the possibility that the cosmological constant may not be constant, rendering it nearly impossible to predict the fate of the universe.
