I did some research, I hope you don't mind. 1000000000 Lions v. 1 Sun 1 Earth = 5.972 x 10^24kg 1 Sun = 1.989 x 10^30kg 1 human = 65kg 7 billion humans = 4.55 x 10^11kg 1 lion = 420 lb = 190.5087954kg 1 billion lions = 1.905087954 x 10^11kg Despite the amount of lions, it is still small compared to the Sun. Even when compared to the Earth, the lions still do not come close. Think about this; there are around 7 billion people on Earth right now. The average mass of a human is 65kg to a lion's 190.5087954kg. Now, multiply the mass of the average human by the population, and what do you get? You get 4.55 x 10^11kg. The mass of all currently existing humans on Earth exceeds that of the hypothetical 1 billion lions, and we don't even come close to the mass of the Earth, much less the Sun. Therefore, the lions will be completely and utterly destroyed by the Sun. Feel free to check my math if you wish. [spoiler]Praise the Sun. :)[/spoiler]
