What's the name given to 0 degrees longitude?
114340
0° of the longitude is the Prime Meridian (located in Greenwich, England). You use that to base your longitude measurements either eastward (+180°) or westward (−180°).

Zero was introduced initially, not as a number to be used in computation, but as a position marker to distinguish between such numbers as 123, 1203, 1230, and 1023. The Maya, about the 1st century ad, used a small oval containing an inner arc to denote zero. About five centuries later the Hindus began to use a circle or a dot as a symbol for zero; the dot later fell into disuse. These Indian mathematicians wrote numbers in columns, and they used the zero to represent a blank column. The Hindu word for zero was sunya, meaning empty, or void; this word, translated and transliterated by the Arabs as sifr, is the root of the English words cipher and zerZero was introduced initially, not as a number to be used in computation, but as a position marker to distinguish between such numbers as 123, 1203, 1230, and 1023.

Well suppose you want to find antipodal positions on the earth. The earth is only approximately a sphere (it is actually closer to an oblate spheroid), so the mathematical definition of an antipodal point on the earth does not quite hold. \n\nIf one location on earth is at 23 degrees North latitude, and 10 degrees West longitude, the antipodal point will be at 23 degrees South latitude, and 190 degrees West longitude (but 190 degrees West longitude will be more often called 170 degrees East longitude). \n\nThat is, just add 180 degrees to the longitude, and switch the North latitude to South latitude (or vice versa).

Still Zero since (0 / 2 = 0).\n\nWhen double below zero is used it is normally just to put emphasis on the fact that it is very cold.

If you mean the latitude, then it's 41.873712° N (+41.873712°).\n\nIf you mean the magnetic declination, then it's currently\n14°15'W changing by 0°3'E/year.

Assuming your point of origin has the coordinates of y latitude N/S and x Longitude E/W, the opposite point would be y latitude S/N (The opposite direction. If origin is north, then the opposite would be the same value south.) The Longitude is figured by subtracting 180 degrees from the origin's value, and drop the minus sign, then changing the direction from east to west, or west to east.\n\nIf this does not make sense, post a detail, and I will try to clarify.

RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from an arbitrary zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the vernal equinox point (also known as the First Point of Aries), which is the place in the sky where the Sun crosses the celestial equator at the March equinox.\n\nRA is measured in hours, minutes, and seconds, eastward from the vernal equinox (sometimes it is also given in degrees). Being closely tied with sidereal time, it is both a unit of time and of angle. An hour of right ascension is equal to 15 degrees of arc, a minute of right ascension equal to 15 minutes of arc, and a second of right ascension equal to 15 seconds of arc. An alternative measure, used in navigation, is Sidereal Hour Angle. The main difference being that RA is measured Eastward, and SHA is measured Westward.\n\nRA can be used to determine a star's location and to determine how long it will take for a star to reach a certain point in the sky. For example, if a star with RA = 01:30:00 is at your meridian, then a star with RA = 20:00:00 will be in the meridian 18.5 sidereal hours later.\n\n\n[edit] History\nThe concept of right ascension has been known at least as far back as Hipparchos who measured stars in equatorial coordinates in the 2nd century BC. But Hipparchos and his successors made their star catalogs in ecliptical coordinates, and the use of RA was limited to special cases.\n\nWith the invention of the telescope, it became possible for astronomers to observe celestial objects in greater detail, provided that the telescope could be kept pointed at the object for a period of time. The easiest way to do that is to use an equatorial mount for the telescope, which allows the telescope to rotate at the same rate as the earth. As the equatorial mount became widely adopted for observation, the equatorial coordinate system, which includes right ascension, was adopted at the same time for simplicity. Equatorial mounts could then be accurately pointed at objects with known right ascension and declination by the use of setting circles. The first star catalog to use right ascension and declination was John Flamsteed's Historia Coelestis Britannica (1712, 1725).

Your home coordinates are the number of degrees and minutes a direct line from your home to the centre of the earth deviates from the equator and the Grenwich Meridian. There are many ways you can find this out using various maps and things (like the website below).\n\nBut I doubt that there is anyone out there psychic enough to guess it. But I'll give it a try anyway...\n\nN38o59' W77o05'\n\nHow did I go?

0 Latitude is the Equator, and 0 Longitude is the Prime Meridian.  The Equator is the latitude line that is always closest to the sun, no matter what time of year.  The Prime Meridian is where the time zones start.  Try googling it for more information.

The limit as sky goes to zero from the positive direction would be ground.\nLim    = ground\nsky-->0+\n\nThe limit as sky goes to zero from the negative direction is space.\nLim    = space\nsky-->0-\n\nSince the limit from the + site does not equal the limit from the - side, the limit does not exist.

My first thought would be the location 0 degrees latitude and 0 degrees longitude. This is a point in the Atlantic Ocean off the coast of Africa. \n\nFor mapping purposes all latitudes and longitudes are counted from that point.
