Earth would be extremly cold for creatures to live.
2. Earth would be floating any where. If there is no pulling power by th sun, it is just like a ball.
3. Earth could disappear! It can go to blackhole and just pop away
Q. Do you want to choose either 2 suns or no sun? WHY?
Acutally, the sun is going to die 45billion years later, what would happen to earth 45billion years later? Suck into black hole? Noooooooooo!!!! But even two suns can collapse together making one giant black hole which is the same end for our earth. So I rather choose two suns because it will end fast.
Brilliant question. That sun is creeping me out, BTW.
