black hole: A location of room acquiring a gravitational area so intensive that no issue or radiation (which includes gentle) can escape.
cosmos: (adj. cosmic) A expression that refers to the universe and every thing in just it.
exotic: An adjective to describe something that is hugely unusual, weird or international (this kind of as exotic crops).
extraterrestrial: (ET) Anything of or from regions past Earth.
discipline: (in physics) A location in room the place specified bodily results work, these as magnetism (developed by a magnetic subject), gravity (by a gravitational industry), mass (by a Higgs industry) or electrical power (by an electrical industry).
galaxy: A team of stars — and generally dim matter — all held with each other by gravity. Huge galaxies, such as the Milky Way, generally have a lot more than 100 billion stars. The dimmest galaxies may possibly have just a handful of thousand. Some galaxies also have gas and dust from which they make new stars.
holes: (in electronics) The absence of generally anticipated electrons in a semiconductor crystal
insight: The capability to obtain an exact and deep comprehending of a predicament just by contemplating about it, as an alternative of doing the job out a answer by way of experimentation.
mass: A variety that shows how significantly an item resists speeding up and slowing down — fundamentally a evaluate of how a lot issue that object is created from.
subject: Some thing that occupies space and has mass. Everything on Earth with matter will have a property described as “body weight.”
Milky Way: The galaxy in which Earth’s solar process resides.
Nobel prize: A prestigious award named soon after Alfred Nobel. Best recognized as the inventor of dynamite, Nobel was a rich male when he died on December 10, 1896. In his will, Nobel left substantially of his fortune to build prizes to those people who have accomplished their finest for humanity in the fields of physics, chemistry, physiology or drugs, literature and peace. Winners receive a medal and massive money award.
orbit: The curved route of a celestial object or spacecraft close to a galaxy, star, world or moon. One particular complete circuit all over a celestial entire body.
peer: (noun) Someone who is an equivalent, primarily based on age, education and learning, position, coaching or some other attributes. (verb) To look into one thing, hunting for particulars.
bodily: (adj.) A time period for items that exist in the real globe, as opposed to in recollections or the creativity. It can also refer to houses of resources that are due to their sizing and non-chemical interactions (these as when a person block slams with pressure into one more).
physics: The scientific study of the mother nature and properties of matter and energy. Classical physics is an rationalization of the mother nature and homes of make any difference and strength that relies on descriptions this kind of as Newton’s guidelines of movement. Quantum physics, a field of analyze that emerged later, is a more correct way of conveying the motions and actions of matter. A scientist who will work in such parts is regarded as a physicist.
relativity: (in physics) A principle created by physicist Albert Einstein showing that neither space nor time are continuous, but rather afflicted by one’s velocity and the mass of issues in your vicinity.
star: The primary making block from which galaxies are produced. Stars establish when gravity compacts clouds of gas. When they grow to be very hot sufficient, stars will emit light and from time to time other forms of electromagnetic radiation. The sunshine is our closest star.
telescope: Typically a light-collecting instrument that helps make distant objects look nearer as a result of the use of lenses or a blend of curved mirrors and lenses. Some, nonetheless, gather radio emissions (power from a various part of the electromagnetic spectrum) via a community of antennas.
idea: (in science) A description of some component of the all-natural planet based mostly on in depth observations, exams and rationale. A idea can also be a way of organizing a wide body of know-how that applies in a broad array of circumstances to reveal what will come about. Contrary to the widespread definition of theory, a idea in science is not just a hunch. Suggestions or conclusions that are based mostly on a idea — and not yet on company data or observations — are referred to as theoretical. Researchers who use arithmetic and/or existing information to challenge what could transpire in new circumstances are identified as theorists.
universe: The entire cosmos: All things that exist through house and time. It has been expanding because its development all through an celebration known as the Huge Bang, some 13.8 billion yrs in the past (give or choose a couple of hundred million several years).
