A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy can escape it. Albert 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. 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.
The hertz is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is s−1, meaning that one hertz is one per second or the reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz).
The Summer Olympic Games, also known as the Summer Olympics or the Games of the Olympiad, is a major international multi-sport event normally held once every four years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent was held in 2024 in Paris, France. This was the first international multi-sport event of its kind, organized by the International Olympic Committee (IOC) founded by Pierre de Coubertin. 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.
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events occur.
Time is the continuous progression of our changing existence 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, 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. Scientists have theorized a beginning of time in our universe and an end. A cyclic model describes a cyclical nature, whereas the philosophy of eternalism views the subject from a different angle.
Athletics is a group of sporting events that involves competitive running, jumping and throwing. 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 10 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 all events in the universe, including human decisions and actions, are causally inevitable. 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 used in North America 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. Outside of Canada and the United States, athletics is the official term for this sport with 'track' and 'field' events being subgroups of athletics 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.

It is also considered one of the company's five biggest events of the year, along with WrestleMania, Royal Rumble, SummerSlam, and Money in the Bank, referred to as the "Big Five".
A historical drama is a dramatic work set in a past time period, usually used in the context of film and television, which presents historical events and characters with varying degrees of fictional elements such as creative dialogue or fictional scenes which aim to compress separate events or illustrate a broader factual narrative. The biographical film is a type of historical drama which generally focuses on a single individual or well-defined group. Historical dramas can include romances, adventure films, and swashbucklers.
