• Atheists, where did the universe come from, and more importantly, HOW?

    ******Saying "I don't know" (while honest), is not a satisfactory answer to me; I'm looking for answers!******** Did the universe 1. come from nothing 2. always exist or 3. come about some other way? Most importantly, how are any one of these three occurrences possible?

  • What is the fourth dimension?

    Best answer: Time is "A" fourth dimension not "The" fourth dimension ----The spatial 4th dimension is just that, another axis like X, Y, Z. Sometimes denoted Z' (Z prime) at 90 degrees to X, Y, and Z. TIME is an dynamic dimension an inherent, constant motion in ALL matter in the direction of the... show more
    Best answer: Time is "A" fourth dimension not "The" fourth dimension ----The spatial 4th dimension is just that, another axis like X, Y, Z. Sometimes denoted Z' (Z prime) at 90 degrees to X, Y, and Z. TIME is an dynamic dimension an inherent, constant motion in ALL matter in the direction of the 4th spatial dimension at the speed of c / square root of 2.

    The fourth dimension is also the direction we travel to get to a parallel 3D universe.-----imagine a 2D universe with only X and Y dimensions (like a sheet of paper) a stack of such universes , like papers in a stack lay in the direction of the extra dimension----the third dimension------So to travel from one 2D Universe to a parallel 2D universe we travel along the 3rd Dimension (up and down). Expand the principle to a 3D universe, we must travel in the 4th Dimension to get to the next parallel 3D universe.

  • Are all lasers electron beams?

    Best answer: They are *never* electron beams, always photon beams (the "l" in laser means light, and light is made of photons). Moreover, the basic idea of lasers can be adapted to other systems (like for instance masers) but it cannot be adapted to electrons for a very fundamental reason: electrons are fermions,... show more

    Moreover, the basic idea of lasers can be adapted to other systems (like for instance masers) but it cannot be adapted to electrons for a very fundamental reason: electrons are fermions, constrained by Pauli's exclusion principle, and therefore they can't be put in a coherent superposition.

  • Why is the pythagorean theorem such a big deal, why does squaring 3 variables make a difference from the unsquared?

    Best answer: it can be used to find the third number if you don't know it because its the law of triangles which is a natural constant. if a²+b²=c² then you know that a b and c have a relationship so if you don't know one then it can be found by doing math. if I remember correctly, c is always the hypotenuse or the long... show more

  • The Earth moves at a speed of 30 km per second. How is that even possible? It's mind-blowing!?

    Best answer: Newton said that an object in motion stays in motion, unless another force acts upon it. Since there is no air resistance or friction in space there is nothing there to really slow out it down.

  • Why does a metal object on a string move when hung above a person's body?

    I have tried the so called baby gender test with a ring and the ring does move a lot when it hovers over my hand, my leg, my husband and my dog, so anything with a pulse. Why does that happen, what kind of waves are moving it?

  • What is the waves in wave-particle duality?

    Wave-particle duality says that a particle behaves both like a particle and a wave, but not both at the same time. I understand a particle very well: it is a point of space.

    Wave-particle duality says that a particle behaves both like a particle and a wave, but not both at the same time. I understand a particle very well: it is a point of space. I do also understand waves, but not in this case. First, a wave is an disturbance, or an oscillation. For example, sound waves is disturbances in the air. And water waves is disturbances on the water surface. However, then we comes to the wave-particle duality. If we use the wave model of an electron, then what is the electron wave an disturbance in? It cannot just be a wavelike motion through space. Or is this explained by quantum field theory, where the electron is an disturbance in the electron field? Secondly, what does the wavelength represent? As already stated, the electron cannot just be moving through space in a motion that resembles a wave, with an up and down motion. When electron waves propagate, they does not swing up and down, as water waves do. Then what does the wavelength mean in this situation? Sorry if it sound like I have done zero research, but it is very messy to try to find information about quantum mechanics on the internet.

  • Could time travel be possible considering this logic?

    Best answer: Time IS movement of matter---indeed a constant INHERENT movement of matter at c / square root of 2 in the direction of the 4th dimension. even when objects are still, time still flows as the motion vectors are the same, like two cars matching speed on a highway.

    Best answer: Time IS movement of matter---indeed a constant INHERENT movement of matter at c / square root of 2 in the direction of the 4th dimension. even when objects are still, time still flows as the motion vectors are the same, like two cars matching speed on a highway. Motion occurs in our frame of reference when the 4D vectors of the other particle or object differ.----Like when one of the cars veers off to the side and the drivers can then sense RELATIVE motion of a few mph while the highway speed may be 60 mph, for example.---of course the greater the angle of veer., the greater the relative speed.---and since there is no highway speed change the other car will appear to DROP BACK a bit on the highway.

    Thus in our 3D universe motion is relative based on difference of "Veer angle" of the 4D time motion vector. All motion we see is RELATIVE slower motion, while time motion moves at a good portion of light speed. the greater the vector angle, the greater the apparent relative speed and the more BACK in time the moving objects slips relative to the other. (Time dilation) at () degrees the relative speed maxes out--we call it "light speed" (c) time for it stops relative to us as we speed away from it.---beyond 90degrees of veer it drops out of our frame of reference as it is going backwards in time relative to us.

    Gravity is also tied to time. Gravity is the inertia we feel from this 4D motion as we travel around CURVED space around a massive object. It feels like we are being drawn inwards to it

    Don't worry about Paradoxes in backwards time travel----Paradoxes do not happen.--Its like an electric switch relay wired into itself via the Normally close terminal, to turn off when the coil is activated. To ask what happens when the normally open terminal is closed, is nonsensical. You can't cut your own timeline or do ANYTHING that would affect your existence or even the timing of embarkation of your time adventure. As the switch cuts off its own power to draw the throw bar down and lacks the energy to do so, YOU would lack the energy to carry out a time line cutting action. It would seem that a mysterious force were holding you back from some actions---But not really a force, but a lack of it. You could not pull the trigger to kill your grandfather while the gun was pointed at him---because you would not exist if you did, so you can pull it only so far, but not enough.--Aim in a different direction, though and the gun will work fine.

    Time travel---perhaps this movement is simply a switching from one parallel universe to another each representing a specific instant in time. These parallel universes may be at different "frequencies" like different radio stations--after all Matter is ultimately waves anyway. Changing wave attributes of matter would cause you to move from one universe or time instant to another. Ift hese wave attributes could be identified and a way to change them developed, then you can time travel by simply changing the wave attributes of your body's particles to match the "frequency" of one of these parallel universes that represents an instant of time in the past, say in 1950, and you would become a part of THAT universe---and Back in time.

  • This is a weird driving question but, How do I maintain a certain speed without going up or down while driving?

    Best answer: You are right, it is annoying to be behind someone who can't reasonably keep a constant speed.
    1) I listen to the sound of the engine (or the sound of the tyres, if it's a rough surface). If the note changes, I adjust the speed. I don't listen to music when driving!
    2) The tachometer is more accurate to judge speed. If you note the reading when at the right speed, you are more able to correct a difference before it is a significant change. Play music if you want to.
    3) Fit cruise control if it is not already there. I don't have it, and have never had it, in my long driving career.
