#3 Bye Bye Sun
We all are constantly being bombarded by the news that the sun is getting hotter and hotter and its harmful rays are causing great harm to humans leading to many terminal diseases.
However, here is another aspect – presumably, some 5,000 years from now, chances are that the hydrogen will cease to exist. If so, does it also not imply that Sun in totality will be gone?
Without sunlight will any life, be it humans, animals, or plants, be able to survive on this planey?
