I was trying to come up with a solution to the timeline when hypothetically speaking the sun would stop shining ( or emitting radiation). Now, gravitational issues aside (the sun as a body still there), how long would it take for median temperature to drop beyond freezing point around the globe? How long would it take for the oceans to completely freeze, and how long would it take for the air to become liquid or solid?
I'm wondering if anybody did a research on this topic, I searched the internet but could not find anything about the subject.
Also, as the sun burning hydrogen in its core it becomes more efficient, therefore, gets hotter (as I understand). Somewhere I saw that it increasing its output about 10% in billion years. How long would animals have left on this planet, and how would it affect us humans in.... let's say 10,000-50,000 years from now.
Thank you very much
