Will sun consume Mercury, Venus and Earth?
As all we know that sun is an enlarged fire ball that sustains life on earth.
You will be amazed to hear that this life giving force wont remain this generous and eventually it will run out of hydrogen fuel.
If such thing happens the result will be complete anarchy.
In about five billion years sun will completely run out of fuel and it will turn into a red giant.
Apart from losing its life sustaining ability, it will go on a hunt in its neighbourhood, the solar system.
Possibly it will swallow up Mercury, Venus and Earth.
