Ignoring the other concerns, some flat Earth conjecturists explain the observed surface "gravity" by proposing that the flat Earth is constantly accelerating upwards. [13] Such a conjecture would also leave open for explanation the tides seen in Earth's oceans, which are conventionally explained by the gravity exerted by the Sun and Moon.
The Old Bedford River, photographed from the bridge at Welney, Norfolk (2008); the camera is looking downstream, south-west of the bridge. The Bedford Level experiment was a series of observations carried out along a 6-mile (10 km) length of the Old Bedford River on the Bedford Level of the Cambridgeshire Fens in the United Kingdom during the 19th and early 20th centuries to deny the curvature ...
Image from space: The spherical surface of planet Earth. Spherical Earth or Earth's curvature refers to the approximation of the figure of the Earth to a sphere.The concept of a spherical Earth gradually displaced earlier beliefs in a flat Earth during classical antiquity and the Middle Ages.
However, the conspiracy theory claiming the Earth is just a flat disc hanging in space is nothing new. The Economist found that there has been a resurgence of the belief since 2013, as shown in ...
On small scales space appears flat – as does the surface of the Earth if one looks at a small area. On large scales however, space is bent by the gravitational effect of matter. Since relativity indicates that matter and energy are equivalent , this effect is also produced by the presence of energy (such as light and other electromagnetic ...
The frame could be free fall under gravity, or far in space away from any forces. The surface of the Earth is not an inertial frame, as it is being constantly accelerated. We know that the surface of the Earth is not an inertial frame because an object at rest there may not remain at rest—objects at rest fall to the ground when released.
Science has long been the target of conspiracy theories, some of which have persisted for centuries. A man who remains convinced that the Earth is flat intends to prove it once and for all, and an ...
An application of the theorem is seen when a flat object is somewhat folded or bent along a line, creating rigidity in the perpendicular direction. This is of practical use in construction, as well as in a common pizza-eating strategy: A flat slice of pizza can be seen as a surface with constant Gaussian curvature 0. Gently bending a slice must ...
