There are many examples on the internet, but not all are trustworthy and the trustworthy accounts are purely sujective and often occur in conjunction with psychotropic drugs suggesting the experiences are due to hallucination. The subjective evidence for astral projection that there is does not suggest that specifically astral projection is occurring.

If you are already familiar with the lorentz law I would structure the essay around the equation and the timeline leading to the acceptance of the lorentz law. Starting with a brief on the lorentz law, leading from previous knowledge of electric and magnetic fields to how it was derived by Lorentz from his experiments and how it explained the generation of electromagnetic radiation.

Be specific.

"Anti-noise" is essentially destructive interference and this occurs frequently in nature. Though as sound usually expands spherically, it usually cannot be distinguished with the human ear from noise which echos indirectly. Some animals may utilise destructive interference as part of their vocal communication in order to create an easily recognised unusual set of sounds.

An asshole is the area between the sphincter of the anus and in fact does consist of material. The amount of matter in the asshole can range from a few milligrams of bodily fliuds to several grams of fecal matter or some other object. A black hole is structurally very different, it is a singularity bounded in our space-time by an event horizon. Black holes can theoretically contain any amount of mass and black holes containing the mass of elementary particles have been created in particle accelerators. These black holes were very unstable and did not exist for more than a few quantum seconds. Stable black holes contain substantially more mass than that which could be considerred part of the asshole.

There is no such thing as a black hole field and black holes are singularities, points in space, not polygons. If by field you are referring to the "volume" within the event horizon, then the answer is uncertain. Stephen Hawking postulated that matter and energy which enters the event horizon does eventually escape in the form of Hawking radiation and as a result of this slow loss of energy in 10^50 years the black hole will become unstable and collapse releasing the remaining energy. You may also be interested in black hole thermodynamics.

If you are using minkowski space in the scale in which special relativity applies, yes for both. From another vector with another direction it would be observed as a moving point in space and slowly changing relative velocity. Google "light cone".

If superman can travel so fast he can go back in time he must be able to generate more than infinite kinetic energy and would have the energy needed to exit the event horizon. Whether this means he could make contact with the singularity or exist in the event horizon is unknown.

My best estimate would be between 0.5 seconds and 5 minutes as this is the usual time it takes to purchase a hot dog to a reasonable extreme. If this is a trick question it could be anywhere between a quantum second and 150 years.
