Global Cash Access was founded in July 1998 as a joint venture of three payment processing companies: BA Merchant Services (majority-owned by Bank of America), First Data, and USA Processing Inc. [3] [4] First Data contributed the assets of its gaming business, First Data Financial Services, which provided cash services at over 800 gaming properties; it had purchased the business earlier in ...
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 ...
The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. [2]: 145 The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, [34] [35] [36] soon after the formation of the Earth's crust and the Earth itself.
2 billion High estimate until the Earth's oceans evaporate if the atmospheric pressure were to decrease via the nitrogen cycle. [98] 2.55 billion The Sun will have reached a maximum surface temperature of 5,820 K (5,550 °C; 10,020 °F). From then on, it will become gradually cooler while its luminosity will continue to increase. [86] 2.8 billion
c. 10 −36 seconds: Electroweak epoch begins: The Universe cools down to 10 28 kelvin. The strong nuclear force becomes distinct from the electroweak force.; c. 10 −33 seconds: Space is subjected to inflation, expanding by a factor of the order of 10 26 over a time of the order of 10 −33 to 10 −32 seconds.
According to evidence from radiometric dating and other sources, Earth formed about 4.54 billion years ago. [7] [8] [9] The current dominant theory of planet formation suggests that planets such as Earth form in about 50 to 100 million years but more recently proposed alternative processes and timescales have stimulated ongoing debate in the planetary science community.

The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia. [32] [33 ...
The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia. [2] The earliest evidence of life found in a stratigraphic unit, not just a single mineral grain, is the 3.7 Ga metasedimentary rocks containing ...
