would suck if they created something like a portal or wormhole and we all get pulled in. That's why I think it's crazy they wanna make small scale black holes with them collider things. They say that it would be so minuscule that it couldn't happen but honestly they don't know what would happen. They shouldn't be messing with artificial black holes. Just because they think its safe doesn't mean jack. Anything could happen. Ok I'm starting to scare myself haha

Well this is all jolly fascinating stuff. I cannot wait to see what the results of the mission to examine these "x-points" read like. I also wonder if it is possible to create in a laboratory, a much smaller version of the circumstances in which these things occur. I mean, going out there and looking for them is all sorts of spectacular, but if we can learn ways in which we could control the effect, then we could recreate it small scale,and study the heck out of it to our hearts content.
Unless you're a scientist, the concept of temperature in space will be very confusing to you. For example, in deep space, where the temperature can be over one million degrees, you would quickly freeze to death exposed to that temperature.

what temperature would you say it is in space outside of earth's atmosphere in direct line of sight with the sun. or do astronauts and satellites restrict their orbits to the dark side of the earth to avoid direct sunlight?
Wow that's crazy.. Can the temperature really be a million degrees and freeze you? I'm intrigued.

The HAARP array in Gakona, ak, is a phased antenna array and can be aimed at the ionosphere in a 45 degree cone. Same for the HAARP array in Tromso Norway.
the web site for Tromso provides some technical but not impossible explanation of how it works.
Basically, the right frequency pulsed in the ground array with the correct timing between antennas can cause the ions in a very narrow region of the ionosphere to begin circulating...with greater speed over time.
this can punch or seal a hole in the ionosphere. the correct frequency causes the ions to surf. toward light speed.
This article mentions millions of degrees kelvin and then about 3 degrees kelvin. So scientists report the millions of degrees kelvin, but it feels like only a few degrees kelvin (which is on the order of -260 degrees Celsius).

In a space capsule, it's electromagnetic radiation from the sun that controls the temperature, not the temperature of space, so on the voyages to the moon they did a "barbeque roll" to even out the 400 degree temperature differential from the sunlight side to the shade side of the spacecraft.
Measuring the temperature in space is more complicated than just using a thermometer, since temperature is only a meaningful figure when heat can be efficiently transferred from one body to another. In space, while the temperature of particles can be very high, their density is very low so the ability to transfer heat is minimal. They could be at millions of degrees in the Kelvin range, but since they so rarely collide with one another, the actual phenomenon of temperature or heat exchange doesn't takes place. The temperature in space therefore has to do with the movement and concentration of the molecules, which in turn determines how often they collide with one another to gain or lose energy.
Due to this, the temperature must be determined using Planck's law, which says that every object in the universe emits radiation according to its temperature. By looking at the radiation emitted from space and using this formula, scientists have found that the temperature is about 2.725 K. Different parts of space actually have different temperatures, and the Milky Way galaxy — where the Earth is located — is slightly warmer than many other areas.
840 degrees F is pretty hot.
A key MESSENGER design element deals with the intense heat at Mercury. The Sun is up to 11 times brighter than we see on Earth and surface temperatures can reach 450 degrees Celsius (about 840 degrees Fahrenheit), but MESSENGER will operate at room temperature behind a sunshade made of heat-resistant ceramic cloth.
That's the surface of the sun. Just above that it's much, much hotter.

the temperature of the sun itself is supposed to be near 6000 Kelvin. o.0

First, thanks for spamming a bunch of biblical passages. I'll remember that next time someone whines when I spam some FACTS into a religious thread.
Secondly.... and I only skimmed your post, are you suggesting that these regions of the magnetic field stretching out toward the sun, are the gates mentioned in those passages?
Wouldn't that make the sun heaven?

we then have a question about the sun. why is space cold, when our planet is hot. if the earth's atmosphere protects us from heat from the sun, then entering space should fry both occupants and vehicle.
