"They suggest that for a long period of Earth’s early days, the planet was covered by one solid plate, like an eggshell. Scientists still aren’t sure how we might have gotten from an early solid crust to our present-day tectonic plates."

 

Much in the same way an egg's shell cracks when boiled I would assume? That internal heat build-up, creates a pressure build-up, which cracks the hard surface.

This entanglement stuff is so freaking amazing, I'm still not sure I completely believe it.

Let me ask a question that keeps popping up in my head:

 

So Mars is the new hotness, now everyone and their grandmother, from national space agencies around the globe to private enterprises, are all super interested in going to Mars.  One thing we are not seemingly interested in, that I think we should be, is building an outpost on the moon.  Why build an outpost on the moon?  What are the benefits?  

 

There are several.  

 

It's an exercise in building something on an extraterrestrial piece of rock.  Eventually, we're going to send people to Mars and we're going to build something over there.  Now, the challenges to building on the moon and building on mars are not exactly the same, but there will definitely be many of the same problems to face, namely radiation.  We can simulate concepts of radiation shielding on computers, but that's not the same as doing it in practice, and what better place to practice than right in our own back yard (galactically speaking).  Other challenges include protecting the outpost from meteor and comet strikes (Mars, unlike the moon, has an atmosphere, but it is very thin) and the effects of low gravity over prolonged periods of time on people.  If we face all these challenges for the first time on Mars and something goes wrong then the people there are SOL because help is at best 7 months away, likely much further (depends on how the orbits line up).  If something goes wrong on the moon we at least have a chance to save the people.  Mars is going to present its own unique problems but some of this stuff we encounter and overcome on the moon will be applicable.

 

A base on the moon can also be used as a staging and refueling station for missions into our solar system.  Eventually maybe you could actually build spacecraft there and just start the journey there.  Some of the biggest hurdles to space missions are getting through the Earth's atmosphere and escaping its gravity well.  We burn the majority of fuel in our current spacecraft just getting off this planet.  If we refuel the spacecraft on the moon we're already past the atmosphere and a good chunk of the way out of the Earth's gravity well (the moon has its own gravity well but it is quite small comparatively speaking).  We would use a fraction of the fuel to take off from the moon and get into deep space than what we use to get off the Earth, leaving that much more fuel to go wander around the solar system and take pictures and probe, or whatever.

 

So my question is, why are we not trying to build an outpost on the moon?  This to me seems like the clear next logical step.  It seems a lot of people are wanting to skip this step and go right to Mars and I think that's a costly mistake (both in therms of money and lives).

And just think about it. They could make a Big Brother tv show ON THE MOON.

Nazis and lizard people...  Lizard Nazis!  Oh crap!  :blink:

 

Edit: I didn't even know about Elon Musk talking about building a base on the moon, I just saw the story on that just now.  I've been thinking about this for a good while now.  It just seems like the next logical step.  Great minds think alike, I guess...  :shifty:

It's an enormous expense for very little gain.

You are right about it being logical next step tho.

Because due to human nature, it'd be best trying to achieve the actual planet first and then the moon because otherwise we would use the moon as an weapon instead first. Still a high possibility we still would.
