How cold is too cold? > General Discussion

I have a knife made by Mission that is titanium. One of its benefits is that it does not become brittle at very low temp. How cold does it have to get before it is unsafe to shoot an AR? Will anything crack, shatter, or be damaged at some point?

so long as you dont try to bumpfire while immersed in a vat of liquid nitrogen I wouldnt worry too much

If it gets that cold, You will quit working before your AR will.

Nice last name.

Back in the early years I had to beat a few kids up on the playground, too.

Absolute zero.

−273.15 °C or −459.67 °F

The temperature where all molecular motion ceases.

Does that answer your question?

has absolute zero ever been achieved?

I saw an AF police M16 snap the buttstock by closing a car door with it during a midwest winter cold snap.

It is impossible to achieve.

Within a few millionths of a degree and with lasers to stop individual atoms it has.

Does the military require testing involving temperature extremes? Where could I get a look at that info?

I was perusing (yes "perusing", bygod) an aricle one time which pointed out that when some experiment like this was carried out, for that brief moment, it was likely that the coldest place in the entire farkin' universe was on the planet earth.

Kind of made me sit back and go *Wow* at what science can do.

But then a mighty wail escaped from the depths of my soul accompanied by a great gnashing of teeth. I stood and yelled at my computer screen: "You bastards can create the coldest farkin' spot in the known universe but you can't grow my hair back?! WHAT GOOD ARE YOU, MR. SCIENTIST?! I ASK AGAIN: WHAT GOOD ARE YOU?!

I hope they can sleep at night.
