Highlight:

Physicists watch quantum particles tunnel through solid barriers. Here's what they found. [View all] Judi Lynn Aug 2020 OP

Possibly it's evaporating and reorganizing on the other side judesedit Aug 2020 #1

there's a range of probabilities qazplm135 Aug 2020 #4

If they just appear on the other side, how would you explain the precession? Jim__ Aug 2020 #7

because the magnetic field is only inside the barrier qazplm135 Aug 2020 #8

Doesn't the precession imply that they're actually passing through the barrier? Jim__ Aug 2020 #9

your own link qazplm135 Aug 2020 #10

From my link: "When particles are inside the barrier, they precess. Outside it, they don't." Jim__ Aug 2020 #11

no it doesn't qazplm135 Aug 2020 #13

OK. I can't argue about quantum theory. But the article does talk about the velocity of the ... Jim__ Aug 2020 #15

I don't know what else to tell you qazplm135 Aug 2020 #16

My belief is based on explicit statements in the article. Jim__ Aug 2020 #17

yes INSIDE qazplm135 Aug 2020 #18

Yes, inside: "... if they can learn anything about velocity of the atoms ... Jim__ Aug 2020 #19

to also see if they can learn anything qazplm135 Aug 2020 #20

you clearly don't understand qazplm135 Aug 2020 #29

You clearly didn't read the article clearly. The barrier was NOT a mass. It was magnetic. . . . nt Bernardo de La Paz Aug 2020 #48

The reason why you can't burrow through a wall qazplm135 Aug 2020 #49

You claimed it was because it had mass. It does not have mass. . . . nt Bernardo de La Paz Aug 2020 #50

I was talking about quantum tunneling in general qazplm135 Aug 2020 #51

You wrote it was impossible to be in the barrier because of MASS. Further, photons aren't affected Bernardo de La Paz Aug 2020 #52

Sigh qazplm135 Aug 2020 #53

Quantum gravity not been proven, so, no, mass does not affect transmission of photons through mass. Bernardo de La Paz Aug 2020 #54

Einstein?? qazplm135 Aug 2020 #55

So now you are against people making "general statements" the way you made general statements. Bernardo de La Paz Aug 2020 #56

lol qazplm135 Aug 2020 #58

From what I've read about quantum physics, there is no solid mass judesedit Aug 2020 #22

for the purpose of this qazplm135 Aug 2020 #28

1) Rubidium atoms are not "subatomic", 2) Precession only occurs inside the barrier Bernardo de La Paz Aug 2020 #47

they "precess" inside the barrier qazplm135 Aug 2020 #57

by the way, another experiment "Definitively" found it was near instantaneous qazplm135 Aug 2020 #59

I probably sound stupid, but you mean kind of like a drill? judesedit Aug 2020 #21

I was referring to a paragraph in the article. Jim__ Aug 2020 #24

you are fixated on the precession qazplm135 Aug 2020 #30

"When particles are inside the barrier, they precess. Outside it, they don't." Jim__ Aug 2020 #33

so what? qazplm135 Aug 2020 #34

That means they were inside the barrier. Jim__ Aug 2020 #35

No qazplm135 Aug 2020 #36

They were inside the barrier regardless? Jim__ Aug 2020 #37

Again you are obsessed with the precession qazplm135 Aug 2020 #38

No, I'm not obsessed with precession. Jim__ Aug 2020 #39

I've REPEATEDLY answered it qazplm135 Aug 2020 #40

YIKES! SkyDaddy7 Aug 2020 #45

This is where I need a sarcasm detector qazplm135 Aug 2020 #46

Particles can appear from empty space... Buckeye_Democrat Aug 2020 #14

Thank you for the food for thought. It really is a fascinating subject judesedit Aug 2020 #23

Interesting. According to one of the books I read (by Brian Greene? Roger Penrose?)... CaptainTruth Aug 2020 #27

Yes, it doesn't tunnel through qazplm135 Aug 2020 #32

Thanks for the reply. Perhaps I should have said "continuous." CaptainTruth Aug 2020 #42

I agree it isn't "tunneling" in the sense qazplm135 Aug 2020 #43
