From 10 14 (100 trillion) to 10 40 (10 duodecillion) years. By 10 14 (100 trillion) years from now, star formation will end, [5] 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.
The universe has appeared much the same as it does now, for many billions of years. It will continue to look similar for many more billions of years into the future. The galactic disk of the Milky Way is estimated to have been formed 8.8 ± 1.7 billion years ago but only the age of the Sun, 4.567 billion years, is known precisely. [69]
More than $100 trillion in household wealth is expected to be passed down as part of the Great Wealth Transfer, the largest in U.S. history, according to a new report.
A regular kalpa is approximately 16 million years long (16,798,000 years [16]), and a small kalpa is 1000 regular kalpas, or about 16.8 billion years. [citation needed] Further, a medium kalpa is roughly 336 billion years, the equivalent of 20 small kalpas. [citation needed] A great kalpa is four medium kalpas, [17] or about 1.3 trillion years.
With a number, "billion" can be abbreviated as b, bil [2] or bn. [3] [4] In standard form, it is written as 1 × 10 9. The metric prefix giga indicates 1,000,000,000 times the base unit. Its symbol is G. One billion years may be called an eon in astronomy or geology.
The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [11] End Ordovician: 440 million years ago, 86% of all species lost, including graptolites
