Conjurer Posted September 21, 2019 Share Posted September 21, 2019 I am sure everyone will think I am crazy for saying this, but I doubt it will change everyone's opinion since I am new and have more down-votes. I will just go on and say it. I remembered the Planck Time and Planck Length being 10^-33 sec and 10^-34 cm. Checking the wiki: It says the Planck Time was 10^-44 sec, and the Length is currently 10^-35 m, which is also 10^34 cm. When I was looking at the wiki a couple of weeks ago, the Planck Length was in the mid negative 40 decimal places. Then the Planck Time was only off by only one decimal place. Either someone is screwing around with the wiki here, or the Planck Length and Time doesn't seem to remain constant. https://en.wikipedia.org/wiki/Planck_length https://en.wikipedia.org/wiki/Planck_time It makes me wonder if this figure could somehow be tied to the number of alternate universes there are, and this number is changing, altering the values of these constants through time...

If one had a decent grasp of physics, one could simply derive the values. Unless you are claiming G, h or c have changed, which would indeed be crazy, this is baseless. Not having a decent grasp of physics is why you get the down-votes, and why you will convince nobody. Link to comment Share on other sites More sharing options...

Well, you could check other sources (such as the sources referenced by Wikipedia). For example, http://astronomy.swin.edu.au/cosmos/P/Planck+Units seems to be consistent with the values you quote. Maybe someone had the wrong values in Wikipedia for a while (you could check the edit history) or, quite possibly, your memory is incorrect. (Human memory is notoriously unreliable and easy to change.) 30 minutes ago, Conjurer said: It makes me wonder if this figure could somehow be tied to the number of alternate universes there are, and this number is changing, altering the values of these constants through time... If you are thinking of something like the "Mandela effect" then this is, pretty obviously, also down to the plasticity of human memory. (If you want to discuss this further, start a new thread. It is off topic here.) Link to comment Share on other sites More sharing options...

Unless you are claiming G, h or c have changed, which would indeed be crazy, this is baseless. Right? Wouldn't it be absolutely crazy? Just like I mentioned? If something was changing there, I would vote for the gravitational constant of the universe. It could be possible that dark energy is due to the number of alternate universes, and maybe it could have measurable affect here on Earth counteracting gravity. I admit, science has not advanced far enough to make a real conclusion about it. We could only hypothesis about the cause. The only reason the gravitational constant of the universe is the value that it is comes from what number you would need to multiply two masses together, divided by the radius squared to get the correct amount of force. I believed this was done by Newton, but the wiki now claims it was done by C. V. Boys. https://en.wikipedia.org/wiki/Gravitational_constant 1 hour ago, swansont said: Not having a decent grasp of physics is why you get the down-votes, and why you will convince nobody.

(If you want to discuss this further, start a new thread. It is off topic here.) I have given up on trying to memorize those values to the new values, because anytime I go back to them, everyone always believes they are a different value. I just mentioned it, because I have experienced this problem. Then someone just happened to make a thread wondering what the historic values were. Then they are not what I originally remember them to be, and they are not even what people tried to correct me to believe they were from before even. One day, people might look back on this thread and wonder why you two never corrected me to say that I did not actually post what they currently were in the wiki. Then I will be wrong about being able to do that as well. I actually discovered the Mandela Effect due to this, and the fact that Galileo was no longer killed for his blasphemy against religions doctrine that the Earth, not the sun, was at the center of the solar system. Then he was only imprisoned instead, under house arrest. 1 hour ago, swansont said: If one had a decent grasp of physics, one could simply derive the values. Something just occurred to me. I really have no idea how the gravitational constant of the universe even comes into the calculation, or why you would choose to divide by c^5 in the calculation for the Planck Time and c^3 for the Planck Length. Does that even give you the correct units for length and time? Isn't the gravitational constant of the universe unit-less?

Isn't the gravitational constant of the universe unit-less? ...no? The gravitational constant is defined by Newton's law of gravitation, F = G*m1*m2/r^2. Therefore, G = F*r^2/(m1*m2), so the units of G must be Force*distance^2/mass^2. Force = mass*acceleration = mass*distance/time^2, so G has units of distance^3/(mass*time^2).

You have just been shown the reason. 38 minutes ago, Conjurer said: Have you ever heard about the mystery surrounding G, and how no one knows what it could represent? It represents the constant of proportionality between force and the mass and distance. It has the value it does because we use arbitrary man-made units of measurement. I'm not sure what "mystery" you think there is. Link to comment Share on other sites More sharing options...

I was wondering if there were any hidden variables that could describe it, but apparently not. It is just the Planck Length cubed over the Planck Mass times the Planck Time squared. All of which should be constants, so I guess that proves that the gravitational constant should remain constant. Link to comment Share on other sites More sharing options...

The Planck units are based on the quantum of action, now usually known as Planck's constant. Planck called the constant b in his paper, though h (or ħ) is now common.
