A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, has enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. 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 to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.
Probability is the branch of mathematics concerning events and numerical descriptions of how likely they are to occur. The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes are both equally probable; the probability of 'heads' equals the probability of 'tails'; and since no other outcomes are possible, the probability of either 'heads' or 'tails' is 1/2.
The Summer Olympic Games, also known as the Games of the Olympiad, and often referred to as the Summer Olympics, is a major international multi-sport event normally held once every four years on leap years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent Games were held in 2021 in Tokyo, Japan. The International Olympic Committee (IOC) is responsible for organising the Games and for overseeing the host city's preparations. The tradition of awarding medals began in 1904; in each Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place.
The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world.
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions.
The Winter Olympic Games is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France. The modern Olympic Games were inspired by the ancient Olympic Games, which were held in Olympia, Greece, from 776 BC to 394 AD. The Baron Pierre de Coubertin of France founded the International Olympic Committee (IOC) 1,500 years later in 1894, leading to the first modern Summer Olympic Games in Athens, Greece in 1896. The IOC is the governing body of the Olympic Movement, with the Olympic Charter defining its structure and authority. The original five Winter Olympic Sports were bobsleigh, curling, ice hockey, Nordic skiing, and skating. The Games were held every four years from 1924 to 1936, interrupted in 1940 and 1944 by World War II, and resumed in 1948. Until 1992, the Summer Olympic Games and the Winter Olympic Games were held in the same year. A decision to change this was made in 1986, when during the 91st International Olympic Committee session, IOC members decided to alternate the Summer Olympic Games and the Winter Olympic Games on separate four-year cycles in even-numbered years. Also, at that same congress it was decided that 1992 Winter Olympics would be the last to be held in the same year as the Summer Games and that to change the rotation, the edition that would be held in 1996 would be brought forward by two years, being scheduled to 1994. After this edition, the next one was to be held in 1998 when the 4-year Olympic Cycle resumed.
Athletics is a group of sporting events that involves competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross-country running, and racewalking.
The decathlon is a combined event in athletics consisting of ten track and field events. The word "decathlon" was formed, in analogy to the word "pentathlon", from Greek δέκα and ἄθλος. Events are held over two consecutive days and the winners are determined by the combined performance in all. Performance is judged on a points system in each event, not by the position achieved. The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon.
Determinism is the philosophical view that events are completely determined by previously existing causes. Deterministic theories throughout the history of philosophy have developed from diverse and sometimes overlapping motives and considerations. Like eternalism, determinism focuses on particular events rather than the future as a concept. The opposite of determinism is indeterminism, or the view that events are not deterministically caused but rather occur due to chance. Determinism is often contrasted with free will, although some philosophers claim that the two are compatible.

Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. In British English the term "Athletics" is synonymous with American "Track and Field" and includes all jumping events.
WrestleMania is a professional wrestling event held annually between mid-March and mid-April by the American company WWE, the world's largest professional wrestling promotion. Since premiering in 1985, 39 events have been held, with its most recent 39th edition occurring at SoFi Stadium in Inglewood, California on April 1 and 2, 2023. WrestleMania was WWE's first-ever pay-per-view (PPV) produced and is the most successful and longest-running professional wrestling event in history. The event has been broadcast through traditional PPV since 1985 and has been available via livestreaming since WrestleMania XXX in 2014, which was WWE's first major event available through this medium. WrestleMania was conceptualized by former WWE executive chairman Vince McMahon and named by ring announcer and WWE Hall of Famer Howard Finkel. It is the company's flagship event and along with Royal Rumble, SummerSlam, Survivor Series, and Money in the Bank, it is referred to as one of the "Big Five", WWE's five biggest annual events of the year.
The Royal Rumble is a professional wrestling event, produced annually in late January since 1988 by WWE, the world's largest professional wrestling promotion. It is named after the Royal Rumble match, a modified battle royal in which the participants enter at timed intervals instead of all beginning in the ring at the same time. After the inaugural 1988 event aired as a television special on the USA Network, the Royal Rumble has been broadcast via pay-per-view since the 1989 event and livestreaming since the 2015 event. It is one of WWE's five biggest events of the year, along with WrestleMania, SummerSlam, Survivor Series, and Money in the Bank, referred to as the "Big Five".
The 2024 Summer Olympics, officially the Games of the XXXIII Olympiad and commonly known as Paris 2024, is an upcoming international multi-sport event scheduled to take place from 26 July to 11 August 2024 in France, with Paris as the main host city and 16 other cities spread across metropolitan France, plus one subsite in Tahiti—an island within the French overseas country and overseas collectivity of French Polynesia.
