What is the future of the universe?

The current expansion will continue forever, gaining speed, so that all the galaxies we now observe, 100 billion or so of them, will one day disappear beyond our ability to detect them. Our galaxy will be alone in the visible universe. And then, once the stars burn out, the universe will be truly cold, dark and empty.

What will happen in 100 trillion years from now?

By 1014 (100 trillion) years from now, star formation will end, leaving all stellar objects in the form of degenerate remnants. If protons do not decay, stellar-mass objects will disappear more slowly, making this era last longer.

How did Earth and other planets form?

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

What is the timeline of life on Earth?

These are the Hadean (4.6 billion to 4 billion years ago), the Archean (4 billion to 2.5 billion years ago), the Proterozoic (2.5 billion to 541 million years ago), and the Phanerozoic (541 million years ago to the present).

What is life timeline?

A life timeline can be a handy tool for memoirists and memory-keepers of all kinds. It will help orient you in time when writing or sharing stories orally, and it will provide essential prompts for stirring your memories and allowing you to delve into your past.

What major factor determines the future of the universe?

The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.

What is the reason why Earth is different from other planets in the solar system?

Earth is the only planet not only in the solar system but also among all the others discovered in the universe in which humans can breathe in. Earth is a terrestrial planet and is placed at a perfect distance from the sun called the habitable zone, which is neither too close nor too far away.

How was the Earth formed timeline?

Dense metals sank to the centre of the Earth and formed the core, while the outside layer cooled and solidified to form the Earth’s crust 4,500,000,000 years ago. Water vapour was released into the Earth’s atmosphere through volcanism. It then cooled and formed the Earth’s first oceans 4,400,000,000 years ago.

What happens to matter when it comes into contact with the universe?

Close encounters between astronomical objects gravitationally fling planets from their star systems, and star systems from galaxies. Physicists expect that matter itself will eventually come under the influence of radioactive decay, as even the most stable materials break apart into subatomic particles.

What will happen when the Earth’s rotation slow down?

Due to the gradual slowing down of Earth’s rotation, a day on Earth will be one minute longer than it is today. The widening East African Rift valley is flooded by the Red Sea, causing a new ocean basin to divide the continent of Africa and the African Plate into the newly formed Nubian Plate and the Somali Plate .

What is the latest revision of the far future?

This is the latest accepted revision, reviewed on 4 September 2021. This article is about the far future as postulated by science. For related lists, see List of future astronomical events, Far future in fiction, and Far future in religion.

What are the alternative future events in science?

A number of alternative future events are listed to account for questions still unresolved, such as whether humans will become extinct, whether protons decay, and whether the Earth survives when the Sun expands to become a red giant .
