The video is dedicated to catastrophic events that will occur in the next billion years. So, in eight thousand years there may be a problem of the ten thousandth year that can arise with the software because four figures are used to represent the year in dates, not five figures.
After 50 thousand years, a new ice age will come, and Niagara Falls will disappear. For 500 thousand years, the Earth is likely to face a large asteroid one kilometer in diameter, and half a million years later, an eruption of the supervolcan will occur. By that time the star Betelgeuse will turn into a supernova.
After 50 million years, Phobos will fall to the surface of Mars, and after a hundred million an asteroid with a diameter of more than 10 kilometers will hit our planet. At the same time, Saturn will completely lose the rings. 400-500 million years later, there will probably be a powerful gamma outbreak that can destroy the ozone layer on Earth.
The sun will also increase its brightness, which will lead to climate change. The level of carbon dioxide will drop sharply, making photosynthesis impossible. Finally, in a billion years, the oceans of the Earth will disappear because of the powerful greenhouse effect.
