afaik the beams didn't melt, they were just weakened by heat, which happens at well under the melting point. And the molten metal that conspiratards were talking about wasn't steel, but aluminum,...

As far as I can tell, this is not the case, and dark energy is influenced by gravity.

Sorry, probably me not being a scientist and saying shit wrong. What I meant to say is that it seems to only expand intergalactic space. As I understand it, dark energy isn't causing the volume of...

The farthest that my layman's brain could get on it is that it's the default tendency of empty space to expand when not acted upon by a dominant gravity field. It's more a property of space itself...

My point was that you couldn't maintain a constant rate of acceleration of 1g for very long (within interstellar travel time frames). For some reason when I first approached this problem I just...

Would the fuel mass be so prohibitive if it weren't solid rocket fuel, but fissile material or some other dense fuel? I mean you're already going to need to provide the thrust required to make the...

Was watching this video and I was wondering why the simplest solution for artificial gravity shouldn't be just having the spaceship's floor...

At a glance, it appears that Phil Plait's version of a black hole supports my claim that you see an infinite amount of time elapse before your eyes as you fall in.

Thanks for the replies, but its pretty over my head. I still don't really understand how a single photon can interfere with itself. I think the problem is this shit cannot be described using an...

Figures. :(

I've watched tons of shit on this and I've finally found a video that comes close to explaining it in language that speaks to me. I don't know if I'm...

I'll do your experiment next time I cook. I think I know what it feels like to hold something that's hot for a little too long, and this really seemed different from that. That said I know that...

The issue though is that the dousing with water seemed to change the way I felt the heat. The pan felt quite warm when I was holding it, but within 2-3 seconds of running the water onto it, it...

This is probably an easy one for you.

As I'm rinsing a hot frying pan with cold water, the handle feels hotter right away. The pan is made out of steel (I guess), and the handle is just an...

If they're otherwise in the exact same location on earth, yes by a couple of femtoseconds probably. But variation in sea level or crust density at your location would have many orders of magnitude...

I am not above learning some math. As far as my current math skills, I haven't taken a math class in 15 years, and that was high school calculus. I took structures in architecture school but that...

Isn't entanglement being FTL analogous to saying that a shadow can move FTL, i.e. no information is being transferred in either case?

I think you have a good enough picture of my ignorance level wrt QM, what resources would you direct me to learn more at this point? Keeping in mind that the source needs to be dumbed down to a...

can more than one photon comprise the same wave?

Yeah I still completely don't get it. How can a wave be an omnidirectional sphere propagation that has the same amount of energy even as it gets exponentially larger? I just don't understand what...

More silly questions. If a photon is absorbed, does its wave disappear? Say one photon was created in a vacuum in an area of space that was completely devoid of energy. The wave from that photon...

who needs ascii when I know how to use autocad?

The green object is a cross...

Wait, I think you may be misunderstanding the setup. The tube is only closed on one end. All I meant to set up is that there can be no reflection that focuses photons in the direction of the open...

I feel like I've watched 100 youtube videos about the wave-particle duality and I still don't really get it.

I'll contrive a probably retarded example and ask you how it behaves:

Say you have a...

X approaches infinity in both observations. I think you got my meaning but I thought I'd fix the glaring typos here in case anyone else reads it and it confuses them.
