If you could fold a piece of paper in half 50 times how thick would it be?
In theory, that peice of paper would be thick enough to accomplish the distance from earth to the moon.
=================================
as i said...in theory. but hypothetically
it would just be a normal piece of paper that is 0.02cm thick.
=================================
Answer #2:
The paper would still be the same thickness as it was before you folded it.
But you're probably asking for the thickness of the big folded wad. Naturally,
that depends on how thick the paper is before you start folding it.
You haven't mentioned what kind of paper you'd like to use, so I can't actually
calculate a thickness. All I can tell you is that whatever the thickness of the
paper is, the final folded form will be 250 = 1,125,899,907,000,000 times as thick
(rounded to the nearest million times).
20-lb bond, widely used for home printers, varies from about 0.0038 to 0.0045 inch thick. If I use 0.004 inch for convenience, and multiply it by the rounded number above, I get
(0.004 in) x 250 = 4.5 x 1012 in = 3.8 x 1011 ft = 71 million miles, rounded,
or just under 298 times the distance to the moon.
(That's if you're careful to squeeze out all the air between the layers after you fold it.)
How you freeze a corona just by hitting the bottom?

False. When a hypothesis is shown to be incorrect, it does not necessarily mean the experiment is a failure. It provides valuable information and contributes to the scientific process by ruling out one possible explanation, allowing for further refinement of the hypothesis.
What happened in 1961 and will not happen again until 6009?

How do mind reading games work?
Mind reading games typically involve a series of cues, prompts, or questions that are designed to lead participants to choose a specific option or reveal personal information. The game facilitator may use techniques like cold reading, psychological manipulation, or subtle prompting to create the illusion of mind reading. Ultimately, mind reading games rely on the power of suggestion and the participant's willingness to believe in the illusion of mind reading.

Why do older people forget things more frequently than younger people?
It's called age. As we get older, all parts of our bodies weaken, including memory. Plus there is what is called, 'Alzheimer's disease'. Every part of a human body weakens and dies, the memory part of the brain is a part that goes fast in some. It's called life!
When a human is born his brain is "empty" and is continously filled with a lot of information. By experiencing and repeating things synapses connect to specific brain regions. The more information of one kind is coming to the brain more and more synapses will be connected. Slowly the Brain is getting a specialist for certain tasks. That's for example the reason why People who play the Piano since they were Children are better in playing than people who startet later.
Most People are constantly giving order to their lifes and many days are just like the day before. So the Brain is specializing every day a bit more and not capable of processing any new information coming towards it.
Persons who suffer from 'Alzheimers disease' mostly forget what they did only minutes ago or in bad cases Years while they can perfectly remember what they did when they were young.

Poe's poem, "To F___s S. O___d" (To Frances S. Osgood) was originally typeset with em-dashes to disguise some of the letters in her name, but the WikiAnswers question field won't accept most punctuation marks. Unfortunately, the title won't reproduce properly in the answer box, either, but it originally looked something like this: "To F--s S. O--d" (those hyphens should be em-dashes, which are twice as long).
The Grandfather Paradox
This paradox is often used to prove that time travel can't exist. Another "proof" is that we've never been visited by people from the future, which goes to show that time travel will "never" be possible. By changing the past, you change the future in which you are able to travel into the past.
In science fiction treatments of this subject, there are some typical resolutions :
- The killer would still be alive, but unable to leave the past because the time stream was altered.
- When the person changes the past, he (she) returns to an altered future where he never existed, or where time travel never existed.
- The time traveler returns to an alternate future, where he is a different person, having had one different biological parent/grandparent.
- For some reason, the murder never happens. They miss, or run out of bullets, or kill the wrong person (protection of the timeline). In at least one instance, changing the past crashes the time travel method and throws the person back to the future.
Time Loop - when she "did" kill her grandmother, she wouldn't have been born, so then she wouldn't have killed her, so she WOULD have been born, so did kill her, and was erased out of existence, but then was born (and so forth).
Analogy to Self-Murder - That's just like killing yourself, so it would have to be an alternate universe, or one where she was born as another person in another family.
