How will the universe end?
Thousands of stellar events (such as a gamma ray burst) occur everyday and most of these could quickly wipe out life on earth and plunge the Solar System into a state of chaos. However, the odds of this are quite slim, and although earth will perish one day (in about 4 billion years as its orbit decays due to energy lost in the form of gravitational waves) it isn't happening anytime soon. Artist's illustration of a GRB (gamma ray burst) As the earth and our sun will meet their inevitable end, the universe will too. In about 10^10^120 to 10^10^10^56 years, astronomers and scientists have predicted the formation of new universes. The main question is, how exactly will it happen? There are several theories that help explain the ways in which our universe might fall. The Big Freeze In this situation, the universe continues to grow and expand as it does today, but at an exponential rate. The gravitational waves and other forms of energy from various cosmological bodies ar
