A billion years or giga-annum (109 years) is a unit of time on the petasecond scale, more precisely equal to 3.16×1016 seconds (or simply 1,000,000,000 years). It is sometimes abbreviated Gy, Ga (“giga-annum”), Byr and variants.
for instance, How many years is a quintillion seconds?
A quintillion is too large to put in reasonable time terms at all. Even just a quintillion seconds is about 32 billion years, about twice the age of the universe.
significantly, How old is the Earth in human years?
How old is the Earth in human years? If you look up the age of Earth on science websites and in publications, you’ll generally find an estimate of 4.54 billion years, plus or minus 50 million years.
also How old is space?
Scientists’ best estimate is that the universe is about 13.8 billion years old.
How old is the Earth really? Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.

Who discovered Earth?
Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth.
Who is the oldest planet?

How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
What was the first living thing on Earth?
Some scientists estimate that ‘life’ began on our planet as early as four billion years ago. And the first living things were simple, single-celled, micro-organisms called prokaryotes (they lacked a cell membrane and a cell nucleus).
How long have humans existed?
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.
What is zillion number?
A zillion is a huge but nonspecific number. … Zillion sounds like an actual number because of its similarity to billion, million, and trillion, and it is modeled on these real numerical values. However, like its cousin jillion, zillion is an informal way to talk about a number that’s enormous but indefinite.
What is the biggest number ever?
Prof Hugh Woodin, University of California, USA – “One of the largest numbers we have a name for is a googol, and it’s one followed by a hundred zeroes. A hundred zeroes is a lot because each zero represents another factor of 10.”

How much is a zillion?
Zillion may represent ANY very large power of a thousand, certainly larger than a trillion, and maybe even a vigintillion or centillion ! Just as a million had spawned the Chuquet illions, the “zillion” also had many follow ups.
Can you count to a billion in your lifetime?
It would take decades to count to a billion
To count to one billion, says the author, would take over 100 years. It’s unclear if this calculation accounts for breaks for food, sleep, and so on. Assuming no breaks, if you counted once each second, it would still take over 30 years (one billion seconds = 31.69 years).
