Several members of the scientific community remarked that the central lunar highlands resembled regions on Earth that were created by volcanic processes and hypothesized the same might be true on the Moon.

Thus the aim developed, to provide a new time scale for astronomical and scientific purposes, to avoid the unpredictable irregularities of the mean solar time scale, and to replace for these purposes Universal Time ( UT ) and any other time scale based on the rotation of the Earth around its axis, such as sidereal time.

One way to avoid the stigma of an " ism " was to evolve early anti-nuclear groups into the more scientific Green Parties, sprout new NGOs such as Greenpeace and Earth Action, and devoted groups to protecting global biodiversity and preventing global warming and climate change.

Buckminster Fuller has been credited as the first to incorporate scientific ideas into a Gaia theory, which he did with his Dymaxion map of the Earth.

At least one work of fiction, the film Final Fantasy: The Spirits Within, uses Gaia philosophy as a central point to the plot, and may arguably represent a fictional parallel to Sir James Lovelock in the character of Dr. Cid, who is met with skepticism from the scientific and social community when he promotes the idea of a " living Earth ".

Geodesy (), also named geodetics, a branch of earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space.

) had suggested that the Earth revolves around the Sun, but Copernicus's concept was the first to be accepted as a valid scientific possibility.

No energy can reach the center of the cavern, which corresponds to no point a finite distance away from Earth in the widely accepted scientific cosmology.

A drill, Gardner says, would lengthen as it traveled away from the cavern and eventually pass through the " point at infinity " corresponding to the center of the Earth in the widely accepted scientific cosmology.

Another set of scientific arguments against a hollow Earth or any hollow planet comes from gravity.

This melding of scientific and social speculation is clearly present in the novel Voyage from Yesteryear ( strongly influenced by Eric Frank Russell's famous story " And Then There Were None ") about a high-tech anarchist society in the Alpha Centauri system, a starship sent from Earth by a dictatorial government, and the events following their first contact.

Seismology () is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.

Skylab logged about 2, 000 hours of scientific and medical experiments, 127, 000 frames of film of the Sun and 46, 000 of the Earth.

For example, no new evidence will demonstrate that the Earth does not orbit around the sun ( heliocentric theory ), or that living things are not made of cells ( cell theory ), that matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales ( the theory of plate tectonics )... One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed.

Recognizing that it is essential that we understand the challenges that we face as part of the Earth system in order to create appropriate solutions, NOAA conducts an end-to-end sequence of activities, beginning with scientific discovery and resulting in a number of critical environmental services and products.
