The Great Acceleration is the dramatic, continuous and roughly simultaneous surge across a large range of measures of human activity, first recorded in the mid-20th century and continuing into the early 21st century.
It is most commonly used to encompass the variety of changes connected to the rapid increase in human activities which started around mid-20th century, i.e., the Great Acceleration. While the concept stems from research on the climate change, it is used to adopt a more holistic view of the observed changes.
In May 2019 the twenty-nine members of the Anthropocene Working Group (AWG) proposed a start date for the Epoch in the mid-20th century, as that period saw "a rapidly rising human population accelerated the pace of industrial production, the use of agricultural chemicals and other human activities. At the same time, the first atomic-bomb blasts ...
Acceleration in human development process is the phenomenon which has been registered in many populations around the world. This applies equally to the growth of certain anthropometric parameters and the speed of reaching sexual maturity.
This is described by: = + /, where v(t) is the velocity at a time t, a is the acceleration of the spaceship and t is the coordinate time as measured by people on Earth. [ p 20 ] Therefore, after one year of accelerating at 9.81 m/s 2 , the spaceship will be travelling at v = 0.712 c and 0.946 c after three years, relative to Earth.
The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt. An object's average acceleration over a period of time is its change in velocity, , divided by the duration of the period, .
Accelerating change may not be restricted to the Anthropocene Epoch, [12] but a general and predictable developmental feature of the universe. [13] The physical processes that generate an acceleration such as Moore's law are positive feedback loops giving rise to exponential or superexponential technological change. [14]
The diversity of life on Earth is a result of the dynamic interplay between genetic opportunity, metabolic capability, environmental challenges, [95] and symbiosis. [ 96 ] [ 97 ] [ 98 ] For most of its existence, Earth's habitable environment has been dominated by microorganisms and subjected to their metabolism and evolution.
