How would we know if Voyager 1 or 2 crashed into something?

Posted: 30 Dec 2016 02:03 PM PST

I went to JPL's website, but there is nothing there about the possibility of it happening.

Did we just chose a course that at the time looked pretty empty to us?

Is there any significance behind how long it takes your body to get sore after a workout?

Posted: 30 Dec 2016 08:59 AM PST

I know that for me, I can workout at 8am and begin feeling sore that night, and wake up the next day in full blown soreness. Some people experience DOMS where they don't get sore for 2 days. Any reasoning for this? Does it relate to how fast the body repairs damaged muscle fibers?

When did Humans first start eating communal meals, instead of just snacking all day?

Posted: 30 Dec 2016 12:16 PM PST

Animals never sit down and eat a meal together, they just snack all day. When did humans start having meals together, at set times, instead of just eating when hungry?

What evolutionary advantage is there to internal organs feeling pain when without modern medicine, there's nothing a person or animal can do to fix what's causing the pain anyway?

Supposing that all antibiotics became completely useless tomorrow, how prepared would we be to fight off infections with other modern medicine?

Posted: 31 Dec 2016 02:40 AM PST

Would we have no better survival rates than in the middle ages, or can we combat bacterial infections in other ways?

Why does screaming during pain seem to make it feel less painful?

If all of the mass in the universe was to be inside of one black hole right now would the event horizon be larger, smaller or the same size as the universe is right now?

Posted: 31 Dec 2016 05:19 AM PST

also if this was possible would this effect the rate at which the universe expands (especially if the event horizon of this black hole is larger than what the universe is right now)

If hot air rises and cold air sinks, why does the air get colder as you get higher in altitude?

What would a large piece of a substance with a very short half life look like as it decays?

Posted: 30 Dec 2016 04:40 PM PST

A half life of a few minutes or even seconds such as carbon-10.

Are there any everyday macroscopic phenomena that are caused by the quantum behaviour of microscopic particles?

Posted: 30 Dec 2016 12:12 PM PST

Or "can I see the effects of quantum stuff with my own eyes"

If the square root function only returns positive values, does that mean i is positive?

Pauli exclusion principle: how fast does 'this state is occupied' information travel?

Posted: 31 Dec 2016 02:52 AM PST

Assuming it travels with c, does this mean that PEP can be violated for short amount of time?

Could Scientists create a YY... being?

Posted: 30 Dec 2016 07:34 PM PST

After thinking about what I learned in science class in school years ago, I started to wonder if a YY...being, could be created. Surely it could be created, but has it been? And what was the outcome?

If a binary star system goes supernova, do the stars merge?

Posted: 30 Dec 2016 06:57 PM PST

  • Will two binary stars merge when one goes supernova?
  • Can swallowing a star with lighter fuels reverse a supernova? My understanding of supernovas is that they result from a star running out of light elements- so what would an exploding star swallowing a partner star containing lighter fuels do to the exploding star?
  • Would a smaller star that is swallowed up by a supernova disintegrate? How solid or 'fluffy' is the advancing shockwave from an exploding star? Would the external pressure exerted on a smaller star by its exploding partner exceed the internal pressure generated by the smaller star's own fusion?
  • Are prior observations of a star circling a black hole (and being siphoned into its accretion disk) evidence for these scenarios? Do the stars have unusual composition for their size, reflecting a bolus of heavier elements being blown into their heliospheres?

What are examples of physical processes that involve wave function collapse?

Posted: 30 Dec 2016 06:33 PM PST

I learned in an intro quantum mechanics course that taking measurements on quantum particles results in a collapse of their wave functions to a narrow spike, and that the measured quantity assumes a definite value after the measurement. Can anyone give me some examples of these types of measurements? The professor and text were exceedingly vague on this.

Is it possible to retrieve Voyager with our current/near future tech?

Posted: 30 Dec 2016 07:39 PM PST

Let say for some [insert] reason, The fate of humanity is rest whether we can retrieve Voyager or not.

We HAVE to retrieve Voyager by any means back to earth, budget is not an issue no matter how high.

The only limit is our current tech/near future tech.

  • Is it possible ?
  • What tech/method do we use ? (Rocket type / Nuclear is permitted), gravity assist etc)
  • How long it will took to catch with voyager with chosen method?
  • Fastest method VS Most efficient method ?
  • Estimated budget ?

Sorry for stupid question, i'm just curious after i read about :

Are domestic dogs a monophyletic group?

Posted: 30 Dec 2016 10:10 PM PST

By this I mean was there a single wolf domestication event that all modern dogs are descended from or were there multiple domestication events?

Why do we feel the need to itch/other things when we cannot do them?

Posted: 31 Dec 2016 01:44 AM PST

For example you feel the need to itch when you can't since your hands are obstructed in some way.

Sorry for poor example.

What is the physics/chemistry behind why two glass sheets with a thin layer of water in between require a lot of force to separate?

Posted: 30 Dec 2016 04:34 PM PST

I know the basics behind the pressure difference, a bit about van der waal forces but don't quite understand how it really works. Can someone explain in some detail what the physics/chemistry is behind this.

Is there any possibility of a Leviathan or thought-to-be Mythical creature living in our oceans?

If the Big Bang came from a previous Big Crunch, wasn't information destroyed?

Posted: 31 Dec 2016 01:10 AM PST

I've heard about preservation of quantum information (one of the paradoxes that had to be solved surrounding black holes). How does that square with an oscillating-universe model?
