How long is eons ago?
Four hours ago is not an eon. Eon goes back to the Greek aiōn, "age." An age is not easy to measure, and neither is an eon. Both are just really long periods of time, but in science an eon is about a billion years.
What makes up a Eon?
Technically speaking, an eon is made up of two or more eras, which consist of several periods, which are divided into epochs. All of these units of time vary as to their exact length, but most consist of at least millions of years, with eons lasting billions or hundreds of millions of years.

How long is a Supereon?
Explanation: An eon consists of a billion years. However, a supereon is thought to consist of multiple eons: several billion years.
What’s after an eon?
An eon is a billion years in geology. An eon can also be defined as a gigaannum. After that comes a terrannum (1 trillion years) and so on in accordance with the SI prefix system.
How many years are in a Supereon?
An eon consists of a billion years. However, a supereon is thought to consist of multiple eons: several billion years.
How big is an era?
An era in geology is a time of several hundred million years. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is made up of periods, and several eras make up an eon.
What is the biggest unit of time?
The largest unit is the supereon, composed of eons. Eons are divided into eras, which are in turn divided into periods, epochs and ages.
What’s after a eon?
An eon is a billion years in geology. An eon can also be defined as a gigaannum. After that comes a terrannum (1 trillion years) and so on in accordance with the SI prefix system.
How many years is a epoch?
In prediction of tides, an epoch is a period of 19 years, representing one complete cycle of all possible alignments of the sun and the moon. In astronomy, an epoch is the point in time where a calendar, or a defined time frame within a calendar, is considered to begin.

What era do we live in 2021?
The Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth's history when human activity started to have a significant impact on the planet's climate and ecosystems.
What is today’s era called?
the Cenozoic Our current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.

How fast is a yoctosecond?
One yoctosecond is one trillionth of a trillionth of a second (10–24 s) and is comparable to the time it takes light to cross an atomic nucleus. Indeed, the researchers say that such pulses could be used to study the ultrafast processes taking place inside nuclei.
What is the shortest time possible?
Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1.
