How long does the universe have left?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.
How long will the dark era last?
The Black Hole Era, which is predicted to last from about 1040 to 10100 (10 duodecillion to 1 googol) years after the Big Bang, spans an unimaginably long stretch of time, even for astronomical timescales. Imagine a universe with no bright stars, no planets, and no life whatsoever — that’s the Black Hole Era.
Will time ever stop?
“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That’s not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun.
What will happen 5 billion years from now?
Five billion years from now, the sun will have grown into a red giant star, more than 100 times larger than its current size. It will also experience an intense mass loss through a very strong stellar wind. The end product of its evolution, 7 billion years from now, will be a tiny white dwarf star.
How is the universe going to look 3 trillion years from now?
And three trillion years from now, all the galaxies will have passed over the horizon, and faded from view. Future cosmologists will know of only one galaxy: ours. The Universe will appear static and unchanging, slowly cooling away. And this view will be the same from all points of view in the Universe.
What happens to the Earth in 500 million years?
In as soon as 500 million years, temperatures on Earth will rise to the point that most of the world will be a desert. The largest creatures won’t be able to survive anywhere but the relatively cooler poles. Over the course of the next few billion years, evolution will seem to go reverse.
Is there a chance that humanity will end?
If you assume that another 60 billion are yet to be born, our high population levels only give us another 9,000 years or so. Or more precisely, there’s a 95% chance that humanity will have ended by the year 11,000. There are other calculations, but they give similar amounts, ranging from a few thousand to a few million years.
Is the expansion of the universe ever going to end?
Most observations gest that the expansion of the universe will continue forever. If so, then a popular theory is that the universe will cool as it expands, eventually becoming too cold to sustain life.
