1.1–1.2×10 14 (110–120 trillion) The time by which all stars in the universe will have exhausted their fuel (the longest-lived stars, low-mass red dwarfs , have lifespans of roughly 10–20 trillion years). [ 9 ]
[2] [3] Estimates on the number of Earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5] However, a 2016 report estimates an additional 1 trillion microbial species, with only 0.001% described.
Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
So when you talk about a value of $1 trillion, ... lasts 4.7 years, $10 bills last 5.3 years, ... A $1,000 iPhone for 1 billion people. Over 4 million “average” homes in the U.S.
Apple is today the largest company in the world, becoming the first firm to reach a $3 trillion valuation in 2022—four years after it was the first U.S. corporation to surpass the $1 trillion ...
600 million years: HE 1523-0901, the oldest star found producing neutron capture elements forms, marking a new point in ability to detect stars with a telescope. [6] 630 million years (z = 8.2): GRB 090423, the oldest gamma-ray burst recorded suggests that supernovas may have happened very early on in the evolution of the Universe [7]
