    If a nuclear bomb can eviscerate through building/anything laterally, why does it not penetrate downward into the earth as it expands?

    Is the material of the ground that strong? I would think if it explodes and goes through multiple brick buildings for miles it would have no problem building a massive hole in the ground as well? Or is the ground that strong?

    Did the SPCA ever go looking for this Shrodinger cat?

    Favorite Answer:

    Yes, the Serious Physicists' Curiosity Association looks for Schrodinger's Cat all the time, and they often find that the cat is in two different places.

    What is this new cat in the box theory about?

    I sort of know about the cat in the box theory. It is meant as a contradiction to what physicist Niels Bohr had stated.

    However, what is this new theory about? What are they trying to say?

    Can you explain to me in simple layman's term? Thanks.

    Is it possible to make an artificial black hole and use it to generate electricity?

    Favorite Answer:

    No, ZPMs from sci-fi's Stargate franchise are not possible. They are, after all, science fiction. Also, if it were possible to open a black hole and generate electricity, for the electricity to be real, the black hole would have to be real, not artificial.

    What is the airspeed velocity on an unladen swallow?

    Favorite Answer:

    "Well, the most obvious answer- you might think- is “An African or European swallow?” But this is, indeed, where film culture begins to diverge from real life. Because in actual fact, none of the 47 swallow species found on the continent directly bears its name. We might consider the West African swallow, or the South African Cave swallow, however a choice between these two would be completely arbitrary- and neither is sufficiently studied to provide the data we need."

    What causes goats to fall over?

    Favorite Answer:

    There is a breed of goat called a fainting goat which faints and falls over because of a condition in their brain. It may not be a defect but rather a "play dead" defense mechanism.

    There are also fainting cats and rabbits.

    There are not very many because it doesn't always work if the attacker is hungry and eats fainted pray. It is natures Second Harvest Food Bank.

    Physics: Two boxes and a Cord?

    Favorite Answer:

    The masses can be considered as a single mass, since they are connected. (The length of the cord can be arbitrarily short -- so short that the masses are effectively one.)

    So the mass being accelerated is M₁ + M₂. F = Ma, so a = F/M = F/(M₁ + M₂).

    (By the way, submitting many questions in a short time -- you have at least 6 so far -- makes it look as though you are simply trying to get a whole homework set done for you. Don't go there. If you genuinely need help with the problems, post them in the Homework Help section (under Education & Reference), showing what work you have already done and where you got stuck. We can then give help where needed.)

    Physics : What is the speed of gravitation?

    Say, we separated two masses by a distinct space. If one mass moved, how long would it take for the other mass to be effected by its gravity? Is gravitational affect constant or variable?

    How come electronic devices connect in midair like magic with no wires?

    How do you just make something that is in midair and just controls something else that doesn’t touch it at all? 

    Like how are my AirPods in my ears with no wires playing music from my iPhone that’s not even in the same room?  

    Can I then just pick up a leaf and it will play Britney Spears like how does this happen no wires with nothing connecting it like ?

    Do radio waves from blue tooth and cellular and WiFi invisibly travel through our bodily organs?

    Favorite Answer:

    We cannot easily make a technology to observe such waves directly, no, at least not any more than we can see "visible light" waves.  We cannot see the waves because the near waves would block view of farther waves, and thus defeat the purpose of trying to see them.  We can see how the fields or signal strengths vary across space, and thus model the general behavior and imagine how it would look if we could only somehow make it something we could see.  But that is not direct viewing.  It is so far beyond observation and into interpretation that it should not be seen as "real", but that very idea opens up an entire discussion of the nature of perception and reality best avoided for the moment.

    Longer wave (lower energy) electromagnetic signals ("waves") are more easily refracted and reflected by matter than higher-energy waves, and there is definitely a complicated mixture of transmission, refraction, and reflection that occurs whenever long-wave em signals encounter the human body.  There is very little actual interaction (exchange of energy) though.  We do not absorb a lot of energy from those waves, but they will change direction at interfaces between different materials, including human body and air.  Just a matter of how much.  Go learn a bit about basic optics, wave behavior.  water waves are a good physical model to help imagine the behaviors of em waves.
