By their reckoning, Earth’s “day in the sun” has reached 4:, corresponding to its 4.5 billion-year age. By , the 1 billion-year reign of animals land plants will come to an end. At the oceans will vaporize. At noon-after 12 billion year-the ever-expanding sun, transformed into a red gain, will engulf the planet, melting away any evidence it ever existed and nding molecules and atoms that once were Earth floating off into space.
“The disappearance of our plane is still 7.5 billion years away, but people really should cons
ider the fate of our world and have a realistic understanding of where we are going.” Said UW astrophysicist Donald Brownlee. “We live in a fabulous place at a fabulous time. It’s a healthy thing for people to realize what a treasure this is in space and time , and fully appreciate and protect their environment as much as possible.”

The prospects of humans surviving by moving to some other habitable planet or moon aren’t good, Brownlee and Ward contend, becau event if such a place were found, getting there would be a huge obstacle. Various probes nt into space could survive Earth’s demi, and just a few grams of material could arguably carry a DNA sample from every human, they say, but it’s not likely the human species itlf will survive. Long before the planet’s final end, life will become quite challenging, and finally impossible, for humans.
As the sun gets hotter and grows in size, it will envelop Mercury and Venus. It is possible it will stop just short of Earth, the authors say, but the conditions still would make this a most inhospitable planet. More likely, though, the sun will consume earth as well, verin
g all the chemical bonds between molecules and nding its individual atoms out into space, perhaps eventually to form new planes. That would leave Mars as the nearest planet to the sun, and on Mars the fading sun’s glow would be like that of Earth’s moon.
That end is still some 7.5 billion years distant, but by then Earth will have faced a variety of “ends” along the way, the authors say. The dinosaur perished long ago. Still to come are the last elephant, the last tree, the last flower, the last glacier, the last snowflake, the last ocean, the last life.
“it’s a healthy thing go think of the place of Earth among the other planets, and its place in the sun. The sun gave life and ultimately it will bring death.”
