    High School How can Greenland lose 269b tons/year and loose only 269km3?

    The density of ice is 920 kg/m3. Now let's calculate. m = 269 000 000 000 000 kg p = 920 kg/m3 ----------------------------- v=? V=m/p V=269 000 000 000 000 kg / 920 kg/m3 V = 292 391 304 347 m3 = 292 391 304.347 km3 v > 269 km3 *NOTE* I made a mistake in the title. I meant to write 269 km3...

    How can entropy increase in a deterministic universe

    How can randomness exist in deterministic laws, that is contradictory.

    How can entropy increase in a deterministic universe

    How does that cause the entropy to go in the direction of increasing?

    High School Time dilation problem question

    I found a solution by looking at the formula for time dialation. And the I realized that they are experiencing less time tham me, not more. That pretty much solves the problem

    How can entropy increase in a deterministic universe

    Let's imagine a deterministic universe. A one where quantum mechanics simply doesn't apply. Ok. This was the universe of classical physics. Atoms exist, and they behave deterministically. Fine. Now, how can entropy increase in this universe, altough it has the same laws of physics. In a...

    Thank you :)

    High School Is the wave function collapse asymmetrical in time?

    Suppose the Copenhagen interpretation is correct. And we reverse time, what happens. If a wave function has collapsed, and we found a particle somewhere. Now, I turn back time( just hypothetically), what would happen? Would the wave function uncollapse and would the particle then appear at some...

    Is anything possible in the many worlds interpretation?

    In the many worlds interpretation of Qm, is there one universe in which I am a horrible murderer, for example?

    High School Time dilation problem question

    So there is a problem I don't get. I special relativity, things moving relative to me, I see them as experiencing more time/ slower time. Ok...so then I should also see it's velocity decrease. If I see it's clock running slower, so should I it's velocity. V=...m/s So if I see it's time slow down...

    High School Spacetime: Understanding Warps, Limits & Potential Energy

    I would like to know about this: Is there a limit to how much spacetime can warp? If there isn't, can there be? If we imagined an isolated object in the universe, how much would it warp spacetime per 1 cubic meter if it had the mass of 1 kg. No other gravitational forces are acting on this...

    Undergrad Is Quantum Mechanics Redefining Our Understanding of Mass Defect?

    I've just watched a video by PBS spacetime on how an object with more potential energy has more mass, or less, in some cases (mass defect). But there is a problem. Quantum mechanics tells us that a particle has a chance of appearing at difderent places ( wave function), and that it also...

    Undergrad Does spacetime have potential energy?

    Does spacetime have potential energy, and does an object with more potential energy have more mass? (E=mc^2)
