Sedna is an icy solar system body that is so distant, it takes 11,400 years to orbit the sun. It resides roughly 3 times further out from the sun than Neptune, and is two third the size of Pluto. It is one of the most distant objects known in the solar system, and although Sedna is covered in an ice, it appears almost as red as Mars.

Planetesimals theory is a theory most accepted in explaining the origin of the Earth. According to this theory Earth originated from a giant cloud of gas and dust known as solar nebula.

For black holes, distant observers will see only the outside of event horizon, while individual observers falling in to black hole will experience quite another "reality". General relativity predicts that for distant observers out side the horizon, they experience the three space-like coordinates and one time-like coordinate, as they always have. For someone falling in to black hole and crossing the horizon, this crossing mathematically predicted to involve the transformation of you single time-like coordinate in to three time-like coordinates. Along any of these former space like coordinates, they now all terminate on the singularity; you're experiencing as time-like now. All choices always terminate on singularity at least in the case of non rotating black hole. The coordinates which used to measure external time now has a space-like character which affords you some wiggle room, but dynamically, in terms of these new reversed space and time coordinates, you find that no stable orbit about the singularity are possible no matter what you try to do. Without any stable orbits, and the inexorable free fall in to the singularity, relativist often refer to this as the collapse of space time geometry.

One of the most interesting demonstrations of the quantum mechanical nature of light is the double-slit experiment. In this experiment, light is shone through two slits on an opaque plate onto a screen. If one slit is open, the light impacts the screen with greatest intensity at the centre, fading as one moves away from the centre. One might think that, if both slits are open, the result would be the sum of the intensities from the individual slits, but what happens is that an interference pattern is produced, showing that light has wave properties. Even more unusual, if you only fire one photon at the apparatus at a time (and replace the screen with a photographic plate), an interference pattern is still produced, so it would appear as if an individual photon is able to travel through both slits and interfere with itself. If you place a detector at each slit, you will observe that each photon only goes through one slit—but the pattern is now just the sum of the intensities from the individual slits, without any interference pattern.
