Also, so far, actual evidence for a "graviton" zero. Other then the circumstantial evidence that every other force is conveyed by a particle. However, gravity never did fit well with the other forces. I guess it just doesn't play well with others... Gravity just has never been able to be...

incidentally, before we can control gravitons, we have to first prove they exist, and how they can do what light can not. (escape from a black hole) Even if gravitons have no mass, neither does light.

Well, Look at the evidence. The ONLY point we really think the universe expanded faster then light was at the earliest stages of the universe. When all the mass and energy in the universe was collected in one quite small by comparison spot. Imagine what the energy density of the universe...

Oooooh! a faster then light debate? Isn't saying not to let one start, almost encouraging one? Simple proof that faster then light IS possible. All models of the big bang theory pretty much require an inflation period in which space-time itself expands faster then light, allowing for mass...

This kind of thing isn't that uncommon. Sapphire and Ruby are the same stone. Iron or titanium impurities turn it blue, or chromium turns it red. Chromium is highly fluorescent. As to the wavelength of red, it's identical to a ruby laser. (too lazy to look up that wavelength atm). Now if a...

I see. I've never really noticed. Very fascinating. Though I am finding it quite ironic that "cooler" is warmer. :D after searching a little on it, I'm actually surprised I've not caught on to this before. :oops:

Fascinating. I didn't realize that light color was measured in Kelvins Makes sense put that way. Hmm, makes me wish I had taken astronomy now, as that makes sense for star colors. Heh, learn something new every day. ty for the link.

Visible in daylight is going to be an issue. I think if you are trying to point at places in grass at a distance the green dot won't be showing up as easily. Yellow might show up a bit more, then maybe not, as most grass I've seen on gold courses are a yellow green. But yellow is quite...

LOL something tells me you mean in blueish color, not temperature of your monitor. Although it might be interesting to watch what happens when you raise the temp of a monitor to 9000K :D Although I would seriously love to play with a laser powerful enough to do it :D

Nice build as always. You have some really fascinating ideas.

Yeah. I laughed too. Hard.

Ty. And to answer the question, they glow bright red. Identical color to my ruby collection, so I assume there is some chromium present.

Actually I myself use a handheld laser for time to time in delicate wax modeling at my work. someone else built an x-y table with just a phr http://laserpointerforums.com/f44/built-xy-table-need-more-firepower-47137.html Granted, the x-y table is hardly handheld, but the laser head in it is...

I see. I was wondering. ty for elaborating. I've not worked with enough argentium to have found out about that. I see. I'm quite looking forward to your first silver host. It will be interesting to see the results. We have totally different productions specialties, as I do mostly casting...

Hand done. Most of it in the silver, some of it in the wax prior to casting. I carved it with 2.1mm hart burrs, and .4mm round burrs for the recessed texture. I've found what I like for a rock texture. take the hart burrs, cur a lot of notches all in generally the same direction. then rotate...

If your brother can't behave responsibly with a laser, then for the love of god don't let him use yours!!!!!! Handing someone who behaves like that something that belongs to you and is capable of causing damage, makes you an accessory to any damage they cause. There is a lot of legal...

A normal tank can't explode unless there is enough oxygen. with a super-soaker you are pressurizing it with quite a bit of extra air. This DOES change the air/fuel mixture. Also when the fuel starts to run out, there's quite a bit of pressuring air getting into the line it's what makes the...

no worries :D It's actually useful info. I've been contemplating actually making a few silver hosts for sale, so it's something I will have to keep in mind if and when I design them. I'm curious if you noticed the laser host itself get warm at all when it was on?

Yep, It's got the LarryDFW lens assembly in it. As for the textured places between the leaves and stems. All aesthetics aside, (some might like it, some might think it's a little too much) There is a double functionality thing going on there. First it expands the surface area, allowing for...

Just so you know, you might have fried the dvd burner diode from soldering. I killed more then one diode this way when starting out. the trick is you need the iron nice and hot, touch QUICKLY and be done. If the wires get heated just a little too much when soldering, poof. all you get is a...
