Problem

Catastrophic expansion of the sun

Other Names:
Catastrophic increase in solar temperature
Red giant
Nature:
There have been two scenarios developed and discussed for the future evolution of the sun and its probable effect upon life on the planet earth. The first is that the sun becomes a red giant, increasing in size 400 times thereby almost touching the Earth and reducing this planet to a molten rock, and the second, that the sun is affected by solar winds and reduced in size by 40% thereby loosing its gravitational hold upon Earth causing this planet to spiral outward from its present gravitation path.
