You can’t dig a tunnel trough earth, but can you dig a tunnel trough mars?

I know mars's core is solid and lost most of its magnetic field after it cooled. But how „cold" is it inside mars? And could you theoretically build a tunnel straight through the core? What would it take to build this tunnel?

Edit: typos. through mars. I'm an idiot!

Do vaccines improve your immune system in general?

Posted: 14 Jun 2020 07:30 AM PDT

I saw an article that said that their is evidence that some vaccines can improve the effectiveness of your immune response to all diseases, not just the one vaccinated for. It was specifically referring to an incident in Africa where children who were given the measles vaccine seemed to become less susceptible to disease in general. Is this true?

Was Pangaea the only land mass at the time and how do we know that?

Posted: 14 Jun 2020 08:11 AM PDT

I guess this question is about how we know what we know about ancient continents. We know some modern above water landmasses were once sea floors so I assume this must have happened in reverse right? Could there have been continents separate from Pangaea that sunk and are too difficult to find/research today or are we on top of that?

How do we distinguish words in a spoken sentence?

Posted: 14 Jun 2020 07:15 AM PDT

When we speak we can produce words in a sentence and even in languages I don't understand I can make out where one word ends and the next begins even though it is just a mix of sounds. How does this work and what is this phenomenon called? Is it taught or is it an intrinsic property of people?

How are electric motors separated from water within an electric water pump? Surely the water can travel into the motor between the motor shaft and housing ?

How do some tastes linger for long periods even with the briefest exposure?

Posted: 13 Jun 2020 11:47 PM PDT

I understand things like an oil-based capsaicin hanging around your mouth. But I've had medications where even a split-second touch to your tongue will generate a horrific taste that doesn't go away. No amount of rinsing or scrubbing or even brushing with toothpaste can get rid of it for an extremely long period of time. No other food I've encountered has that kind of staying power. If we could generate good flavors like that and have them sit in our mouths with such brief contact, I think we would find a use for it. Is it merely a stubborn chemical hanging around or is there something going on that makes us think that disgusting medicine is still there long after our exposure to it?

Does Heat Capacity affect the insulating ability of a material?

Posted: 13 Jun 2020 11:16 PM PDT

I've been trying to find a website which answers this and some say yes and some say no. hypothetically, if i have 2 materials with the exact same thermal conductivity but material 1 has a higher heat capacity than the other will that make material 1 a better insulator?

With so much effort being put into 'cleansing' modern day TV shows from the slightest amount of death, violence and sex, are there any studies that show evidence of psychological damage in kids exposed to such concepts?

Posted: 13 Jun 2020 10:59 PM PDT

I understand watching violent shows as a child can be impressionable. We all have seen a child body slam another after watching a wrestling match. But I have never seen this behaviour continue past child hood.

The long standing and agressive movement by TV Networks to completely censor all aspects of shows that hint at the unpleasant reality of life makes it seem as though serious psychological damage can occur if exposed to such things

This article by the AAFP cites video games and TV shows as reasons for school shootings and increase violence in the United States. However it does so without referencing any psychological studies that show evidence of this.

https://www.aafp.org/about/policies/all/violence-media.html

TLDR: Is there actual evidence, obtained by test and psychological studies to back up the aggressive censorship of TV shows and the blames on video games as the cause of the increase in violence

Why do we still dont have vaccine or medicines for herpeis?

Why don't we have vaccines for fungi?

Posted: 13 Jun 2020 03:19 PM PDT

We have vaccines for viruses and bacteria, but why not for fungal infections, like athlete's foot? The end goal is the same (teach the immune system to fight a certain intruder), so how come the methods can't be the same? e.g. Couldn't we use inactive (don't know if I'm using that word correctly) pieces of fungal dna used as a type of vaccine, in the same way we do to develop vaccines for other viruses and bacteria? Athletes and cooks could then get a shot for athlete's foot, for example.

When/how did we learn that the North Pole was an ocean and the South Pole was a continent? Considering they were both covered in ice.

Why do AC current transformers offset by 90 degrees?

Posted: 13 Jun 2020 10:41 AM PDT

More specifically, why is the current on the secondary coil just the derivative of the current on the primary coil?

How do moles (“true moles”) navigate?

Posted: 13 Jun 2020 07:34 AM PDT

As a child, i always heard that moles are mostly blind, subterranean creatures and a large part of their navigation underground was a sensory related thing, in a similar way to echolocation or something. But a quick look at wikipedia was fruitless. So, how exactly do moles move around with extremely limited vision?
