Why aren't deep sea brine "lakes" soluble to the surrounding water?

Since the pools have higher concentrations of solute, what prevents the surrounding water molecules from being drawn into the pool and eventually diluting it?

Clearly this doesn't happen since we observe pools, but what's going on at the molecular level?

Why can't LEDs produce radio waves or x-rays?

Posted: 08 Dec 2018 11:52 PM PST

Is it that we just haven't been able to produce an LED with the right bandgap? Are we just not interested in the production of non visible LEDs (with the exception of UV and some IR) or is there a more fundamental reason? And as a follow up question: If we could create a radio wave LED, could we transmit radio wave signals with it?

Why does the ULA Delta 4 Heavy use an asymmetrical engine startup?

Posted: 09 Dec 2018 07:48 AM PST

The three engines are arranged in a line. I saw a post today about a scrubbed launch, and one of the details in the linked CBS story was that the hold order was given "...a half second before the first of the Delta 4 Heavy's three side-by-side Common Booster Core engines was scheduled to ignite and throttle up to full thrust, followed two seconds later by the center and left-side CBCs." I'm certain there's a good reason for doing it this way, but all I've found through Google is the sequence, not the reasoning behind it.

How does a bear knows when wintertime is over ?

Posted: 08 Dec 2018 08:09 PM PST

What i mean is that bears hibernate during winter, but how could they know it is not sleep time any more ?

Do different types if love show up differently inside our brains?

Posted: 09 Dec 2018 06:46 AM PST

For example, does can we distinguish between somebody describing their love for a romantic interest versus their love for a hobby they are deeply passionate about?

How close together are particles and antiparticles created?

Posted: 09 Dec 2018 02:24 AM PST

I am an engineer and I apologize if my question is confused. When multiple particles and antiparticles are created from a gamma photon or from the annihilation of an electron and a positron for example, how far apart are the new particles created from each other? Is there a "fuzzy" region where this happens? If so, what are its dimensions? Do we know what happens at the moment of this creation? If the region is small enough, would the new particle and anti particle annihilate each other? Thank you.

Why are antenna receivers orb-shaped?

Posted: 09 Dec 2018 03:34 AM PST

Hey,

I'm watching some show called Pine Gap on Netflix, but noticed that the receivers are full orbs, with hexagonal plates on it.

What's the reason for this? Wouldn't it be more beneficial if they're just large tray disks?

How does gravity change around the surface of the earth?

Posted: 08 Dec 2018 01:54 PM PST

I've recently made a major relocation, distance, height above sea level, and what not, and it made me curious how gravity changes as we move around the globe. I haven't had enough schooling to understand the professional papers I've tried to read. So i wondered if anyone could point me to a resource that would tell me the gravimetric differences between two points on the planet?

How do satellites remain in orbit and not fall or run away in space ?

Posted: 08 Dec 2018 05:21 PM PST

Hello All ,

How do man made satellites stay in space , and not fall towards earth or run away into space ?

Also , what makes the satellites to revolve around earth ?

Thank you.

Why does it take download speeds time to reach highs and lows?

Posted: 08 Dec 2018 05:17 PM PST

When downloading something, the speed won't jump instantaneously to maximum. It's like it's a damped system, and encounters a resistance to changing, and it needs time to accelerate and decelerate. Why? It's just data. Why should download speeds take time to ramp up?

All fingerprints are different, but how different are they?

Posted: 08 Dec 2018 12:41 PM PST

I'm interested on what data is available on human fingerprint variation. Specifically standard deviations or possibly a graph of what the "average" fingerprint looks like. If not, I'd like to attempt the project if any data is available?

Reason: I'm high and that thought spontaneously came into my head and I think that layout of the average map could be a good logo for a universal human optimization company or something haha

During the Apollo missions how was it possible for the lunar modules to leave the moon with so little fuel?

Posted: 08 Dec 2018 02:31 PM PST

As I understand when something is launch into orbit we need massive amounts of fuel just to leave Earth's atmosphere. I am aware that the moon has 1/6 the gravity of Earth so wouldn't we at least need 1/6 of the fuel? If that is the case how are the lunar modules so small, why doesn't it need the detachable fuel modules that rockets use here on Earth? Does the lack of an atmosphere on the moon has something to do with it?

PS: English is not my first language.

How do you seperate chemical components from a mixture, then identifiy what thise chemical components are?

Posted: 08 Dec 2018 02:05 PM PST

Say I had a mass of dirt and wanted to separate each chemical component, then determine exactly what the structure of each unknown chemical component is. How would I do that?

At any given time, where is most of your blood located?

Posted: 08 Dec 2018 07:12 AM PST

I can't seem to find a definitive answer and figured I'd ask here. At any given moment, which system holds the majority of your blood: arterial system or the venous system?
