Are micro black holes even dangerous?

Posted: 29 Jul 2019 03:33 AM PDT

I don't know if I got this right, but as I understand it black holes interact only through gravity, so if there was a black hole with a mass of the Earth, the Moon wouldn't fall in it, cause gravitation will remain the same. If that's true - what was fear with micro black holes in CERN all about. I know that there was a really low possibility, but hypothetically are micro black holes even dangerous?

When plotting exoplanet discoveries with x being semi-major axis and y being planet mass, they form three distinct groups. Why is this?

Posted: 28 Jul 2019 08:47 AM PDT

I created the following plot when I was messing about with the exoplanet data from exoplanets.org. It seems to me to form three distinct groups of data. Why are there gaps between the groups in which we don't seem to have found many exoplanets? Is this due to the instruments used or discovery techniques or are we focussing on finding those with a specific mass and semi major axis?

Do animals regard machines as other animals and try to bite them, eat them, etc? At what point do they/can they distinguish machines from animals?

Posted: 28 Jul 2019 09:07 PM PDT

I've always wondered if a snake would try to bite a drone that landed near it. If it did, would it try to bite a lawnmower? A CAR? At what point do animals distinguish living things from machines? Has this ever been studied?

Can someone just give me a non-doomsday summary of what we can realistically expect from climate change and how our lives will be impacted over the next 100 years in different regions?

What is happening when our brain is "waking up"?

Posted: 29 Jul 2019 07:52 AM PDT

Do certain processes "boot" later than others? How does the brain prioritize which systems come online first? Why aren't we firing on all cylinders right when we wake up, sometimes taking up to an hour before we're fully cognizant for the day?

How are the North and South poles determined for a black hole?

Posted: 29 Jul 2019 08:36 AM PDT

I was watching a BBC show on black holes and they mentioned that (Hawking) radiation escapes through the North and South poles. My question is, how do scientists determine which pole is North and which is South? And what is the importance to determining which pole is which? Does something different occur at the North vs. South poles of a black hole?

Does getting in shape before having a kid change the child’s genetics/shape?

Posted: 28 Jul 2019 08:41 PM PDT

Let's say I wanted to have kids with somebody in 6 months.

If I hit the gym hard, built my stamina and lean muscle mass a lot during the 6 months, would my child be more likely to be in shape than if I hadn't done that?

What about other factors like tanning, would their skin be more tan if I were tan?

If the answer is yes you can impact them with these changes, what all changes can you make that might impact them?

Is sugar itself harmful, or is it just considered to be harmful because people overeat and/or replace important nutritional food with sugar?

Are their any risks to life expectancy for patients who receive donor organs that are older than their age?

Posted: 29 Jul 2019 05:46 AM PDT

So I have a question.

Does putting an older person's organs in a younger patient have any risks?

Like, would someone who was say 12 years old have the same average life expectancy if they were to have the heart of someone who gave their organ at say 35 years old+?

What actually is a gut feeling? Is it a legitimate kind of natural “defense mechanism” or is it really all in our head (or gut)?

What's the difference between an emulsifier, a solubilizer, and a surfactant?

When I look it up, it all sounds like the same thing and it's confusing me.

At what age do children begin to learn by classical conditioning?

Posted: 28 Jul 2019 04:43 PM PDT

References appreciated! Settling a discussion between friends (both non-parents)

Information on the long term consequences of different types/severity of punishment also appreciated. (I.e. what are the long term consequences of mild physical punishment as a deterrent? Do all degrees of physical punishment carry negative effects?)

Has the mass infrastructure of light on earth affected our brightness in space? Are we more visible from farther away?

Posted: 29 Jul 2019 12:09 AM PDT

The thought crosses my mind when I see pictures of big cities or even entire countries from space. I understand that those satellites are relatively very close to earth, but have all the lights on earth increased our planets brightness in space?

Do spotted/striped animals change their patterns over time or in response to their environment?

Posted: 28 Jul 2019 07:42 PM PDT

Do animals like leopards, zebras, giraffes, tigers, etc. change their stripes or spots in response to their environment over the course of their life? Do these stripe or spot patterns change naturally as the animal gets older or are they fixed from birth?

Did the recurrent laryngeal nerve evolve much later as compared to the superior laryngeal nerve in animals?

Posted: 28 Jul 2019 10:51 PM PDT

In human beings (I'm assuming it's similar to other mammals), the recurrent laryngeal nerve which is the nerve supplying the laryngeal muscles (except cricothyroid) branches off the vagus at the level of the subclavian artery, and the loops around it and comes back up to supply the laryngeal muscles.

The superior laryngeal nerve and it's branches the internal and external laryngeal nerves branch off at much higher, close the level of the hyoid bone.

Proposing a hypothesis: In ancient animals, they only had an external and internal laryngeal nerve (branches of superior laryngeal nerve) which was somehow modified and provided functions of normal sound production/opening larynx for breathing.

The recurrent laryngeal nerve evolved much later in primates which allowed them greater modulation over the laryngeal muscles allowing them to speak.

Does anyone have any evidence to back this up? Or is there any reason for the weird course of the recurrent laryngeal nerve?

Astronomy: Find the distance to Pluto from Earth?

Posted: 28 Jul 2019 01:38 AM PDT

I was wondering if i could calculate the distance to Pluto using only the right ascension of Pluto from earth from two different days and the speed of earth to be able to obtain the difference and utilize that for the parallax and geometry to find the distance from the earth to Pluto. I've tried multiple different ways but i don't seem to understand from where to start the right ascension. I found out that it starts from the vernal equinox but i am still extremely confused. I hope you can help me.

Thank you
