Dark energy: A mysterious, hypothetical energy that is thought to be causing the universe to expand at an accelerating rate.
Exoplanets: Planets that orbit stars other than our Sun.
Gravitational Waves: Ripples in the fabric of spacetime caused by the acceleration of massive objects.

The Space Race: The Cold War-era competition between the United States and the Soviet Union to develop space technology and explore space.
The Sun: The star at the center of our solar system, which provides light and heat to Earth.
The Universe: Everything that exists, including all matter and energy, as well as space and time.
Outer space: The vast expanse of the universe beyond the Earth's atmosphere; devoid of air and other particles.
Near space: The region of space surrounding Earth, extending from the upper limits of Earth's atmosphere to about 960 km (600 mi) above the planet's surface.
Interstellar space: The vast amount of space in the universe between stars.
Intergalactic space: The vast amount of space in the universe between galaxies.
Hyperspace: A theoretical space that is beyond the three dimensions of length, width, and height that we are used to.
Dark space: A term used to describe the vast areas of space which contain very little matter, so that they do not emit any detectable radiation.
Inner space: A term used to describe the space inside planets, stars, and other celestial bodies.
Magnetic space: The area of space around Earth and other planets where the planet's magnetic field is dominant.
Negative space: The space surrounding an object or form that defines its shape and size.
Quantum space: A theoretical form of space in which quantum mechanics is used to describe the properties and behavior of space-time.
Subspace: Any region of space that is smaller than the whole space in which it exists.
Chronospatial space: A theoretical space that combines concepts of both time and space into a single entity.
Virtual space: A digital representation of space and objects within it, created by computer software.
Imaginary space: A space that exists only in the imagination, such as in dreams, fantasy or science fiction.
Plasma space: The area of space where plasma is the dominant form of matter.
Galactic space: The space within a galaxy, which includes the central bulge, the disk, and the outer halo.
Black space: A theoretical space that describes what happens to matter that enters a black hole.
Transdimensional space: A theoretical space that exists beyond the three spatial dimensions and one temporal dimension of our everyday reality.
N-dimensional space: A theoretical space that has more than three dimensions.
Hyperbolic space: A type of curved space in which parallel lines can intersect, and the angles of a triangle do not add up to 180 degrees.
"Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime."
"The concept of space is considered to be of fundamental importance to an understanding of the physical universe."
"Disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework."
"Debates concerning the nature, essence, and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato or Socrates in his reflections on what the Greeks called khôra."
"In Isaac Newton's view, space was absolute - in the sense that it existed permanently and independently of whether there was any matter in the space."
"Other natural philosophers, notably Gottfried Leibniz, thought instead that space was in fact a collection of relations between objects, given by their distance and direction from one another."
"In the 18th century, the philosopher and theologian George Berkeley attempted to refute the 'visibility of spatial depth' in his Essay Towards a New Theory of Vision."
"Kant referred to the experience of 'space' in his Critique of Pure Reason as being a subjective 'pure a priori form of intuition'."
"In the 19th and 20th centuries, mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as curved, rather than flat."
"According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space."
"Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a better model for the shape of space." Note: Due to the length of the paragraph, there are not enough direct quotes to answer all 20 study questions.
