Although the United States Constitution Amendment 7 upholds the right to a trial by jury, it does not explicitly state anywhere that it is a jury of peers. Still, because the amendment says the right to trial by jury shall be "preserved," courts look to the right to trial by jury as it existed when the amendment was passed in 1791. (This interpretation is known as "common law," which courts refer to for all laws that aren't explicit in definition.) Thus, there is a requirement that there is a jury of peers, though it is not explicitly required.
Black holes, unlike the common image, do not act as cosmic vacuum cleaners any more than do other stars. When a star evolves into a black hole, the gravitational attraction at a given distance from the body is no greater than it was for the star. That is to say, were the Sun to be replaced by a black hole of the same mass, the Earth would continue in the same orbit. Due to a black hole's formation being explosive in nature, the object would lose a certain amount of its energy in the process, which—according to the mass–energy equivalence—means that a black-hole would be of lower mass than the parent object, and actually have a weaker gravitational pull.
Only when one is close to a black hole (within the radius of the body which formed it) will the gravitational attraction become greater than the parent body's. One can check this by a thought-experiment: if we are inside a star, some of the star's mass is located in the other direction from us than the centre-of-mass, and thus will attract us away from the centre-of-mass, reducing the gravitational effect. On the other hand, if we replace the star with a black hole, there will be no such reducing effect, as the total mass is in the centre-of-mass, thus always in one direction.
When a meteor lands on Earth (after which it is termed a meteorite), it is not usually hot. In fact, many are found with frost on them. A meteor's great speed during reentry is enough to melt or vaporize its outermost layer, but any molten material will be quickly blown off (ablated), and the interior of the meteor does not have time to heat up because rocks are poor conductors of heat. Also, atmospheric drag can slow small meteors to terminal velocity by the time they hit the ground, giving the surface time to cool down.
According to urban myth, the Daddy Long-Legs Spider (Pholcus phalangioides) is the most venomous spider in the world, but it is harmless to humans because its fangs cannot penetrate human skin. This is false as Pholcus phalangioides can pierce human skin, however, the toxicity of this spider's venom has just a weak effect on insects, let alone humans.
It is sometimes claimed that half, or more than half, of all humans who were ever born are alive today. The claim itself is poorly defined, as there is no definite starting point for the human species. However, even adopting conservative values regarding the origins of humanity, a significantly lower proportion of the human population is currently alive.
It is not true that paper can be folded in half a maximum of seven, eight, ten, or indeed any selected number of times. However there is a loss function associated with each fold, and a practical limit of seven or eight folds for a normal sized (letter or A4) sheet of writing paper is reasonable. A football field-sized sheet of paper was folded in half eleven times on episode 72 of Mythbusters.
