  1. The universe is 14.5 trillion years old...

    Acutally it's 14 billion, so the universe is only three times older than Earth itself.

     

    It's still hard for me, however, to wrap my mind around the fact that the phenomenon of the existence of a rational being exists in a seemingly infinite universe without any example of the same anywhere else. I can see why probability should be irrational in this case. Still, it pounds on my brain every day (I know that this is not rationally relevant).

    That's called Fermi's Paradox (http://en.wikipedia.org/wiki/Fermi_paradox) and I agree with you, it is very fascinating. There is a section in the wiki-article that lists about two dozen hypothetical solutions, you can take a look at that if you like (it's quite long).

  2. My first question was where the oceans came from, since it started out with all landmass.

    It's acutally quite a good question.

     

    Well I find them convincing because they make sense to me. 

    They either make sense and are scientific or not, but "sense to you" does not have any meaning.

  3. From Stef's book Real-Time Relationships:

     

    Love is our involuntary response to virtue. 

     

    One might can add "...if we are virtuous" to make it a bit more clear, but thats the definition most people here are familiar with. You can read the couple of pages in Real-Time Relationships (or the whole book :) ) if you're interested.

    And "greatly overused in many situations & not expressed correctly" is certainly correct, most people don't know smack about virtue hence they don't know anything about love.

  4. Not necessarily. Its density wouldn't necessarily remain constant. IF it were in fact swelling, it would almost have to be changing in density also, or else we'd notice things weighing significantly more.

    While this is an interesting point, it just shifts the explanation from "where's the mass coming from?" to "where's the density change coming from?". Solid matter does not change it's density and for the molten core to change density, it must get heated up. So we are left at the question where all the extra energy might come from.

    yes, by agglomeration ie. space dust and particles of water as well as comets and asteroids being pulled in by the earth's gravity it's not too unimaginable

    That's a valid point, and it happens to be quite a big number (~10^8kg/year), but compared to the mass of earth itself (6*10^24) it is insignificant. Additionally earth loses mass in form of air escaping it and energy being radiated to space. http://scitechdaily.com/earth-loses-50000-tonnes-of-mass-every-year/

  5. I remember the video, watched it a long time ago. 

    My thoughts on this were the following:

    If earth grew 10% in radius/circumference it means that it grows ~33% (1.1³~1.33) in volume. That means earth must've gathered about 30% the mass of itself from some outside source. 30% of earth's mass is like 3 times the mass of mars and I don't see how this amount of mass just happened to merge with earth over time (Afaik it is not explained in the video, but I will watch it again soon). 

    Plus I really dislike theories that claim that "science is all quiet about this". It's either true and can be verified by evidence or it's just made up.
