89. Maybe it can break locally.

Maybe it would just collapse the local galaxy into a black hole or something. Maybe this explains the Fermi paradox. Any civilization that advances enough for interstellar travel or communication will be destroyed by some quack in his basement.

Or maybe it would break the universe, but we're the first civilization in this particular universe to discover the phenomena else we wouldn't still be here.

Or maybe it would just be destructive at a smaller (but still devastating for us) level, like a new type of nuclear bomb.

But yeah, it seems unlikely. In any case, if you don't do it, someone else will, so there's nothing to lose in trying and everything to gain.

We'll build it together and then use our subsequent lottery winnings to fund further research, lol.

Quantum Entanglement, Dark Counts, Coincidence Detection [View all] mindwalker_i Jul 2013 OP

This is me after reading your post : darkangel218 Jul 2013 #1

Oh, sorry about that mindwalker_i Jul 2013 #2

Nooo, its my fault. darkangel218 Jul 2013 #3

I understood every bit of it... nebenaube Jul 2013 #4

Mach-Zehnder interferometers are interesting mindwalker_i Jul 2013 #5

knowing they exist and know what everyone else calls them are two different things. nebenaube Jul 2013 #6

Off the shelf? mindwalker_i Jul 2013 #7

I don't see why what I need would be any bigger then say a .22 slug (for lack of a better reference) nebenaube Jul 2013 #37

See my post currently at the bottom mindwalker_i Jul 2013 #39

Hey, so are you doing this on your own dime? napoleon_in_rags Jul 2013 #8

Pick up that book he mentioned caraher Jul 2013 #9

You're at Powell's in Portland? I'm jealous. napoleon_in_rags Jul 2013 #10

Yeah me too mindwalker_i Jul 2013 #17

I was on Tuesday caraher Jul 2013 #12

BTW, this is still pricey stuff caraher Jul 2013 #13

Youre plan isn't mad, its pure genius. Set up a chemistry lab too. napoleon_in_rags Jul 2013 #14

I gotta say it again - genius. napoleon_in_rags Jul 2013 #15

In chemistry they worry a lot about "technique" caraher Jul 2013 #16

That's how I would start if I were you. napoleon_in_rags Jul 2013 #18

Yeah, I'm doing it on my own dime mindwalker_i Jul 2013 #19

Okay, thanks for that info. Question 2: napoleon_in_rags Jul 2013 #21

Yes, I think it's possible mindwalker_i Jul 2013 #22

Interesting results are good. But be careful young mindwalker.... napoleon_in_rags Jul 2013 #23

Interesting take mindwalker_i Jul 2013 #24

"keep in mind that quantum encryption exists" napoleon_in_rags Jul 2013 #25

Snowden leaked that the govt. is tapping everything mindwalker_i Jul 2013 #26

What's available now is quantum-secured distribution of encryption keys caraher Jul 2013 #28

I think I switched topics without telling anyone mindwalker_i Jul 2013 #31

Aw-ight, sir. napoleon_in_rags Jul 2013 #30

That online lab is a really interesting idea mindwalker_i Jul 2013 #32

It would be a big money saver for all interested. napoleon_in_rags Jul 2013 #33

Sounds like handy stuff caraher Jul 2013 #35

I don't think this can work, but... caraher Jul 2013 #27

But discussing/arguing about it can be fun too mindwalker_i Jul 2013 #36

Part of it is preserving causality caraher Jul 2013 #41

Nature seemed pretty good at enforcing Newton's laws mindwalker_i Jul 2013 #42

I think the Excelitas detectors for education have a 500 Hz dark count rate caraher Jul 2013 #29

Coincidence count rates from downconversion vary a LOT caraher Jul 2013 #11

That's a log of really good information! mindwalker_i Jul 2013 #20

I'm slowly figuring out what you're doing... caraher Jul 2013 #34

Sir, you've just saved me a LOT of pain mindwalker_i Jul 2013 #38

I do want to think a bit more about your experiment... caraher Jul 2013 #40

I just added your message to my file :) mindwalker_i Jul 2013 #43

Well, what I was getting at is only partially-baked caraher Jul 2013 #44

OK, I get it now caraher Jul 2013 #45

I think my explanation isn't quite right, but close caraher Jul 2013 #47

I'm going to have to read through this a few times mindwalker_i Jul 2013 #49

To be clear... caraher Jul 2013 #53

Any progress on the experiment? idkiigmy May 2014 #70

I'm halfway through the Ellerman paper caraher May 2014 #71

First of all, thanks for the links! mindwalker_i May 2014 #72

Cool, keep us posted idkiigmy May 2014 #73

I've already bought the most expensive equipment (I hope) mindwalker_i May 2014 #74

Good mounting hardware helps immensely caraher May 2014 #77

Sorry for he late reply, bu yeah, I've been working with an optical breadboard mindwalker_i May 2014 #79

I might get one of those Sherlines someday caraher May 2014 #80

I like their stuff a lot mindwalker_i May 2014 #81

I actually find aluminum easier to machine than plastic caraher May 2014 #82

So... maybe you should use collinear Type II? caraher Jul 2013 #46

Type II Collinear? mindwalker_i Jul 2013 #48

Ok, I see basically what this is mindwalker_i Jul 2013 #50

Close caraher Jul 2013 #54

Looking at NewLight's site mindwalker_i Jul 2013 #55

You should talk to their sales engineer caraher Jul 2013 #56

Cool! Yeah, I've been e-mailing Jean as well mindwalker_i Jul 2013 #57

a factoid caraher Jul 2013 #58

2000/milliwatt is really good mindwalker_i Jul 2013 #59

Since you're an electronics person... caraher Jul 2013 #60

I've worked with LabView before mindwalker_i Jul 2013 #61

I think that's right caraher Jul 2013 #62

One more thought... caraher Jul 2013 #68

Interesting! This just further solidifies my determination mindwalker_i Jul 2013 #69

The link to Chapter 4 of "this dissertation" does not work for me mindwalker_i Jul 2013 #63

The link is to the full dissertation caraher Jul 2013 #64

I found a much better piece caraher Jul 2013 #65

That workd, thanks again!!! mindwalker_i Jul 2013 #66

OK, but see my other post caraher Jul 2013 #67

Have you checked the fuses? Eddie Haskell Jul 2013 #51

Uhm, what? mindwalker_i Jul 2013 #52

My intuition tells me the past and the future are rather symmetrical about any local present. hunter May 2014 #75

Thank you! I'm a bit surprised at the attention it's gotten as of late mindwalker_i May 2014 #76

You should definitely read the Ellerman paper posted upthread caraher May 2014 #78

Fascinating read. drm604 May 2014 #83

Thank you for your interest mindwalker_i May 2014 #84

To be clear, I wasn't suggesting that you are a quack, you obviously have some knowledge. drm604 May 2014 #85

Oh I didn't think you were saying I was a quack mindwalker_i May 2014 #86

I haven't programmed at the hardware level in decades. drm604 May 2014 #87

Oh now you've done it mindwalker_i May 2014 #88

Maybe it can break locally. drm604 May 2014 #89
