Association football , more commonly known as  football  or  soccer , [a]  is a  team sport  played between two teams of eleven  players  with a spherical  ball . It is played by 250 million players in over 200 countries and dependencies, making it the world's most popular sport. [3] [4] [5] [6]  The game is played on a rectangular  field  with a  goal  at each end. The object of the game is to  score  by getting the ball into the opposing goal.

Weather

Thunderstorm near Garajau,  Madeira Weather  is the state of the  atmosphere , to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1]  Most weather phenomena occur in the lowest level of the atmosphere, the  troposphere , [2] [3]  just below the  stratosphere . Weather refers to day-to-day temperature and  precipitation  activity, whereas  climate  is the term for the averaging of atmospheric conditions over longer periods of time. [4]  When used without qualification, "weather" is generally understood to mean the weather of  Earth . Weather is driven by air pressure, temperature and moisture differences between one place and another. These differences can occur due to the sun's angle at any particular spot, which varies with  latitude . The strong temperature contrast between polar and tropical air gives rise to the largest scale  atmospheric circulations : the Hadley Ce...

Black hole

Image
A  black hole  is a region of  spacetime  exhibiting such strong  gravitational  effects that nothing—not even  particles  and  electromagnetic radiation  such as  light —can escape from inside it. [1]  The theory of  general relativity  predicts that a sufficiently compact  mass  can deform  spacetime  to form a black hole. [2] [3]  The boundary of the region from which no escape is possible is called the  event horizon . Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways a black hole acts like an ideal  black body , as it reflects no light. [4] [5] Moreover,  quantum field theory in curved spacetime  predicts that event horizons emit  Hawking radiation , with  the same spectrum  as a black body of a temperature inversely proportional t...
