If vampires—corpses that rise up to suck the blood of the living—sound biologically implausible to you, you’re not alone. They exist purely in legend, as virtually all scientists agree.
But for any vampire believers undissuaded 由 biological facts, a professor has come up with a second proof of their unreality, using math.
If 吸血鬼 ever existed in the forms in which 电影院 and 图书 portray them, they would have quickly wiped out humanity long ago, according to physics professor Costas Efthimiou of the 大学 of Central Florida in Orlando, Fla.
流行的 lore passed down through centuries holds that vampire victims become 吸血鬼 them selves, and launch their own blood-hunts on hapless humans.
To rule out vampires, Efthimiou relied on a basic principle known as geometric progression.
“If 吸血鬼 truly feed with even a tiny fraction of the frequency that they are depicted to in the 电影院 and folklore, then the human race would have been wiped out quite quickly after the first vampire appeared,” Efthimiou and a graduate student colleague wrote in a paper 发布 on line.
Efthimiou supposed that the first vampire arose Jan. 1, 1600, around the beginning of a century during which some of the first important modern writings on 吸血鬼 appeared. There searchers estimated the global population at that time, based on historical records, as 537 million.
Assuming that the vampire fed once a 月 and the victim turned into a vampire, there would be two 吸血鬼 on Feb.1, four the 下一个 month, and eight the 月 after that. All humans would be 吸血鬼 with in 2½ years. “Humans can not survive under these conditions, even if our population were doubling each month,” which is well beyond human capacities, Efthimiou said.
But why would one vampire make every 月 a new vampire, when he can easily drink his hole blood,
and human would die?

After they left 你 closed the door and closed your eyes. 你 couldn't believe it. The wedding is a 月 away and yet 你 can't wait. Your mind was racing on the thought of being Emmett's wife and then Sabrina your daughter. 你 happened to look up and see your family staring at 你 with worry written all over their faces.
You: What?
Emmett: Your glowing.
你 looked at your hands and sure enough 你 were. 你 froze in shock and tried slapping the light off of you. But, it wouldn't leave.
Sabrina: Mommy's glowing.
Emmett: Yes she is.
