I know that within the major of zoology, there are sub-sciences like mammalogy, ornithology, herpetology, icthyology, entomology, etc. But what are the topics taught in animal science?

I'm trying to find a major that includes the study of animal behavior/animal psychology.

That is, have any of these monsters survived as hurricanes and continued on westwards after crossing land? I suppose while over land, they would probably be downgraded to a tropical storm, but has any of them become a hurricane again on the other side?

These are a few of our Universes amasing things.
Dark energy is said to out weigh all the universes solids by 1000%
Dark matter (they know not what it is) is beleived to be what is causing our Universe to expand at the rate of 66.6% the speed of light in all directions. (and increasing)
Known solids are less than 4% of the mass in our Universe.
We can only see the trillion (M/L) galaxies, but 10 to 100 times this amount of Galaxies are dark and can not be seen by us.
that would make 10 to 100 trillion galaxies.
Why I ask the question is, I am waiting for the day when our knawledge of space is expanded to be able to see beyound our universe as we know it.
If one took (as an example) 25 trillion Galaxies and the average Galaxie had two hundred Billion stars such as our sun,
how many worlds similar to ours might there be?
Why would there be only empty space beyound our Universe?
