    Earths surface temperature at night

    No, Earth doesn't cool by radiation. Only the ground really produces much radiation. Water is a very poor radiator because transparent substances in general don't produce much radiation. Much of the cooling of the ground results from heat energy transfer to the air through conduction. This...

    Japanese Earthquake - was it really that devastating?

    Keep in mind that much of the devastation associated with this earthquake came from the tsunami that it generated which hit the Japanese coast.

    Where are the missing dimensions?

    The idea of other dimensions is difficult to understand because our brains are programed at an early age to think of dimensions as something like the Euclidean dimensions of length, width and height. We need to look at dimensions in the broader sense as variables. The Euclidean dimensions...

    Predictive power of the Farmer's Almanac

    My understanding is that it is based on the cyclic nature of weather. I don't think they look at the sun's sunspot cycles, but those cycles are a cause for some years to be warmer or cooler, etc. Up to now those cycles have been followed a regular pattern, but the new sunspot cycle has...

    Forget ocean levels rising due to global warming what if

    Right. It's proximity to the sun would mean it could have been hit by a large object coming back from the sun on a comet like trajectory. The slingshot affect of going around the sun would have meant it was traveling at an extremely high speed. If it was close enough to the sun as it went...

    Near death out-of-body experiences

    People in a coma can hear everything that is being said even though they have may no feeling and cannot direct movement of any parts of their bodies. As for the out of body issue, I'm not sure whatever energy field might be involved would be able to detect light. If brain waves demonstrate...

    Effect of gravity on atmosphere

    Air molecules move at extremely high speeds which allow them to temporarily move away from the ground. As they move up some of the kinetic energy (i.e., heat) is lost causing them to slow down, but they are also farther from the center of the Earth so the gravitational attraction is lower...

    Science and religion

    How about the Big Bang? The ancient work The Secrets of Enoch describes "all of creation" coming out of an "invisible" object with a "fiery light" inside. The description of what the universe came out of is consistent with the description of a black hole -- an object which cannot be seen with...

    How does Earth cool itself?

    Keep in mind that much of the radiation reaching Earth is not converted into heat directly because plants store it in the form of the electrical bonds that hold complex carbon molecules together. Animals or combustion may eventually convert part of this energy into heat. Cold blooded animals...

    Question about examples used to visualise higher dimensions

    You seem to be making the common mistake of thinking that other dimensions would be like length, width and height in some way. That's because our brains are programmed beginning at an early age to think that those are the only types of things that can be dimensions. The Stephen Hawking of my...

    Why don't the glaciers just melt?

    Partly for the same reason snow remains in shaded areas of my backyard that the sun doesn't reach long after the other snow has melted and air temperatures have risen above freezing. It takes a lot of heat to melt snow and ice because water has a higher specific heat than air and most other...

    At this point the cause is unknown. The terms tends to be used for the North Pacific with the El Nino Southern Oscillation being used for the South Pacific. The PDO is a longer (possibly 20 years) cycle than the ENSO (6 to 18 months) but the ENSO can have periods in which either El Nino...

    Why Michelson-Morley Were Wrong (Wind vs Rain)

    Why should anyone expect an aether wind, if it exists to affect, the speed of light? A speed of a tsunami wave in the ocean is unaffected by the velocity of ocean currents. Speed is determined solely by the depth of the water and the gravitational constant. Even if such a wind could be...

    Experimental evidence that confirms or points toward extraspatial dims
