Predictions[edit]

By 2200, it is predicted that a Type I civilization will form under the Kardashev scale, according to Nikolai Kardashev's extrapolation of 1% energy usage growth per year.^[1]

According to the UN Population Bureau, life expectancy in 2200 will be around 100 for developed countries and the world population will be about 8.5 billion. However, the UN has warned that these projections could be invalidated by any change and progress in future life extension technology and discoveries, as well as changes in future birthrates.^[2]

In his book The Next 100 Years, American political scientist George Friedman predicts that as the century begins, an ongoing confrontation between an increasingly powerful Mexico and the United States will be taking place. Mexico will be an economically and militarily powerful country capable of challenging the United States, while a Mexican majority in southern regions of the United States will have made them a de facto extension of Mexico, with increasing secessionist sentiment. Both countries will be competing for dominance over North America, which will remain the international center of gravity throughout the next few centuries.^[3]

Other predictions[edit]

• 2160 - Some scientists believe there are babies born in 2010 who may still be alive in 2160.^[4]
• March 17, 2160 – Unless changes are made as to when Easter can be observed, this particular March 17 will fall within Holy Week for the first time since 2008 and fall on the same day (Monday) as it did in that year, likely requiring the movement of the Feast of Saint Patrick's Day to another date.^[5]

Astronomical predictions for the 22nd century[edit]

List of the long central solar eclipses[edit]

• December 8, 2113 : Annular solar eclipse,^[6] (9 min 35 s), saros 134.
• June 3, 2114 : Total solar eclipse^[7] of 6 min 32 s, saros 139.
• December 19, 2131 : Annular solar eclipse,^[8] (10 min 14 s), saros 134.
• June 13, 2132 : Total solar eclipse^[9] of 6 min 55 s, saros 139.
• December 30, 2149 : Annular solar eclipse,^[10] (10 min 42 s), saros 134.
• June 25, 2150 : Total solar eclipse^[11] of 7 min 14 s, du saros 139.
  Exceeding 7 minutes of totality, this will be the first time this has happened in 177 years;
  the last one occurred on June 30, 1973^[12] when the Concorde prototype followed the totality spot for 73 minutes.
• January 10, 2168 : Annular solar eclipse,^[13] (10 min 55 s), saros 134.
• July 5, 2168 : Total solar eclipse^[14] of 7 min 26 s, saros 139.
• January 20, 2186 : Annular solar eclipse,^[15] (10 min 53 s), saros 134.
• July 16, 2186 : Total solar eclipse^[16] of 7 min 29 s (very close to the theoretical maximum), saros 139, "crowing" this series.
  This is predicted to be the longest eclipse during the current 10,000 year period, from 4000 BC to 6000 AD (eclipse predictions by Fred Espenak, NASA/GSFC.DEPP).^[17]
