A total of five 23-centimetre-diameter (9 in) boreholes were drilled, two branching from a central shaft and two from one of those branches. In addition to being the deepest human-made hole on Earth, Kola Superdeep Borehole SG-3 was, for almost three decades, the world's longest borehole in measured depth along its bore, until surpassed in 2008 ...
The actual Hill radius for the Earth-Moon pair is on the order of 60,000 km (i.e., extending less than one-sixth the distance of the 378,000 km between the Moon and the Earth). [9] In the Earth-Sun example, the Earth (5.97 × 10 24 kg) orbits the Sun (1.99 × 10 30 kg) at a distance of 149.6 million km, or one astronomical unit (AU). The Hill ...
25 of the holes were excavated by Hawley in 1920 and seven more in 1924. In 1950 Stuart Piggott and Richard Atkinson dug two more Aubrey Holes which brought the total excavated to 35, including one that Richard Colt Hoare may have encountered whilst digging beneath the fallen Slaughter Stone (so named from its reddish coloration) in the early nineteenth century.
The only part of the Earth that turns out to be hollow is a gigantic geode, and soon after the drill moves through it, the hole it created fills with magma. The 1986 animated television show Inhumanoids featured regular visits to the Inner Core in most of its 13 episodes. Each of the three villainous creatures theoretically ruled over certain ...
The inverse problem for earth sections is: given two points, and on the surface of the reference ellipsoid, find the length, , of the short arc of a spheroid section from to and also find the departure and arrival azimuths (angle from true north) of that curve, and . The figure to the right illustrates the notation used here.
The original calculations assumed that the Earth has the same density throughout - and the gravitational force changes as you approach the center, much like the weight of a spring that bounces up ...
It is possible to reduce the various geodesic problems into one of two types. Consider two points: A at latitude φ 1 and longitude λ 1 and B at latitude φ 2 and longitude λ 2 (see Fig. 1). The connecting geodesic (from A to B) is AB, of length s 12, which has azimuths α 1 and α 2 at the two endpoints. [1] The two geodesic problems usually ...
There's also a theory that there is a portal to another dimension and another that says there's a black hole there. Click below for some of the best photos on NASA's Instagram:
