How will the universe end – with a bang or with a whimper?

According to this video it is very much the latter, but only after all life on Earth has long since disappeared.

Host Joe Hanson (@jtotheizzoe) takes us on a journey from near future to far future, and ultimately shows us how the universe might come to an end.

In a video called 'The Far Future of the Universe' host Joe Hanson discusses how Earth and ultimately the universe might end. He says that within 500,000 years we can expect a climate-altering large asteroid to hit our planet, while in a billion years all life will be gone

In a video called ‘The Far Future of the Universe’ host Joe Hanson discusses how Earth and ultimately the universe might end. He says that within 500,000 years we can expect a climate-altering large asteroid to hit our planet, while in a billion years all life will be gone

In the video called ‘The Far Future of the Universe’ he starts with the postulation that most people on Earth alive today won’t be around in 100 years.

3 WAYS THE UNIVERSE MIGHT END

In a closed universe, gravity will halt the expansion and the universe contracts into a single point, known as the Big Crunch.

In an open universe, as described in the video, the universe will continue to expand forever until all the stars go out, known as Heat Death. This concept is discussed brilliantly in Isaac Asimov’s short story ‘The Last Question.’

Finally, in a flat universe, the cosmos continues to expand  forever but at a decreasing rate, ultimately reaching the same fate as an open universe.

In 100,000 years the position of Earth in the Milky Way will have changed to such a degree that the constellations will look completely different in the night sky.

Any time in the next 500,000 years, meanwhile, we can expect Earth to be hit by an asteroid large enough to significantly alter our climate.
