Ask a physicist anything. (6)

That, or:

Sounds like FSM is Light, combined with "the heavens declare the glory of FSM; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. [There is] no speech nor language, [where] their voice is not heard. (FrenchyBearpaw 1:1)

See what I did there? Did ya'? Just replaced "God" with "FSM," and still explained just as much.

Nah, mad libbing doesn't work. Because their God is the right one.

How big would a record ( LP record - Wikipedia, the free encyclopedia ) have to be that the outer rim would need to move at the speed of light to do 33 1/3 rotations in a minute?

How big would a record ( LP record - Wikipedia, the free encyclopedia ) have to be that the outer rim would need to move at the speed of light to do 33 1/3 rotations in a minute?

c = r*w

w = 2Pi/T

T = 60/33.333

r = cT/2Pi = (3*10^8*60)/(2*Pi*33.333)

I'm getting 8.6*10^7 m, but it's pretty late here so the error bars might be quite large....

ETA: And obviously not taking into account relativity here....

As the edge of the disc approaches c, the mass of that circular slice begins to increase. The closer you get the edge to c, the more the mass increases. As it approches c, the mass becomes all-but infinite and the energy required to continue to accelerate the disc also becomes all-but infinite.

So no matter how big your motor, you run out of horsepower before the edge gets to c.

Should I be awed at your creativity now, or later?

I do see that you entirely missed the point. (And apparently the guy in your siggy was not only a "theist" but a devout Christian, of the most difficult and austere order, Russian (Eastern) Orthodox)

D@#n, physics is cool!

I actually liked the post with the equations better Here I thought where you were going was at what speed the record would get ripped apart

Just as awed as your post awed me would be an appropriate response.

I didn't get your point, because, well, you didn't make one. Not one that mattered anyway.

Yep, TD was a stud. Said a lot of really poignant things (you should read some of his works, may help you make an actual point or two ). I included this quote for the theist leaning compadres on CF. You don't have to throw out reality in exchange for the mind numbing beliefs of a literal interpretation.

Fascinating stuff:

Sounds a lot like G-d is Light, combined with "The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. [There is] no speech nor language, [where] their voice is not heard. (Psalm 19)

I think that's a bit of a stretch. Many religious texts speak of divine light of some variety. But none of them, not even Psalm 19, has ever been used to predict the observations made by COBE or WMAP. If you believe the Bible foretold the CMBR, why do you think no one predicted a near-uniform background glow?

 

[Wiccan_Child]

It's just amazing all the details we have on the moon. When was it in a closet?

In the 40's, when it wasn't socially acceptable.

 

[Wiccan_Child]

So if the moon did not break the earths crust what caused plate tectonics, just pressure from below the surface?

The Moon did not cause plate tectonics per se, though the 'great impact' certainly would have contributed towards it. When the Earth formed, its surface was molten rock. It's still in the process of cooling. Nuclear fusion in the core keeps the mantle hot, so the outer crust is geologically active, so it can't cool into one solid crust. It's like a glass of milk that's gone bad, but because bubbles come up now and then, it can't form a single skin.

Yep, I am just a techie, your the physicist.

Theorists trump experimentalists any day Though, naturally, pointing out any flaw in our theories is both welcome and encouraged .

What is your point, though, if not "Ah, that scientific fact vaguely resembles a passage in my particular religious text"? Pointing out that this same comparison can be made with any religion, even made up ones, seems quite apt.

Specific predictions is the realm of scientific theory, right? So why would you want to project that upon an entirely different discipline? Scripture isn't even observation; it's revelation. And it provokes questions such as: of what nature is this "Light?"

The early pioneers of science understood they were merely looking at G-d's handiwork, and attempting to understand the "how," when (sometimes) the why had already been revealed.

Now between CMBR and string theory, I am not claiming that either represents G-d Himself, or even that He operates at that level or in that manner. I am proposing that BOTH exist as a means of insight into who He truly is ...

That dog don't hunt. If you made up a religion, any vague resemblance would have the benefit of hindsight. And just because I see a clear connection, would not mean that you would And it really puzzles me why atheists think that a different religion that may have something just as valid would in any way "invalidate" anything G-d has always reached out to mankind.

This that we're responding to was no better than Insane Duck's madlibs, which can be reduced to "I know you are but what am I?" i.e., entirely bankrupt

How is your made up religion different from ours?

 

[razeontherock]

Your's is not a religion in the least; it's just monkey see monkey do. If you had wrote about your whatever 3500 years ago you might be able to compare notes. Heck, I'd even grant you as recently as 1300 AD. Off the cuff 2 hours ago does not count as foresight

(And I'd expect you t know better than to associate me with religion by now - you really thought you could sneak that in there?
