2.What are the 2 oldest surviving organisms on earth?

good luck on this one, it's fertile ground for conjecture, as to what is an organism and as to the measurement of elapsed time; possible candidates:
-o- a stand of hundreds of huon pine trees on Mt. Read in Tasmania covering about 2 1/2 acres which are probably part the one tree since all these 'trees' appear to have identical DNA, are about 10,000 or 10,500 years according to different sources
-o- bristlecone pines in the Sierra Nevada mountains some of which are about 4,600 or 7,000 years old acording to diffeent sources
< some sources argue that the Stromatilites (cyanobacteria) may be the oldest living species at billions of years old >

18. B2FH refers to what 4 authors?

Burbidge, Burbidge, Fowler and Hoyle - they wrote a paper in Reviews of Modern Physics in 1957 on the formation of nuclei in stars

19. What are "IRS7" and "IRS16"?

looks like they're infra-red sources in the centre of our galaxy, near a possible black hole which is named Sgr A* http://spacescience.nasa.gov/abstracts/LTSA_91_Abstracts.txt

GT is right for #19...it stands for galactic Infra Red Source.

#2- I found this website http://www.firstscience.com/site/articles/davies.asp

Check it out. Seems like one of the oldest surviving organisms on earth are called superbugs.


#3- Large Magellanic Cloud (at a diameter of 20,000)


#4- WIMPs: Weakly Interacting Massive
Particle

MACHOs: Massive Compact Halo Object

Both of these are used to theorize about the dark matter of the Galaxy.


#5- http://ssscott.tripod.com/BigBang.html


#8- I believe the answer is ventricle but I´m not 100% sure.


#12- Kapteyn´s Star seems to be found in the Kapteyn´s Station System, found within the Babylon 5 Universe. The star is about 12.63 lightyears from the Sun.


#16- Between 1350 to 1400 cc, depending on sex and body size.


#17- I think L/D stands for Landing Domain in Aeronautics...sounds about right.

#1. Darwin's 'Origin of Species' was the final convincing publication on that.
