Mark THINKS he knows stuff. Reality shows he DOESN'T! lmfjao!

His education is VERY FLAWED. He did this to himself. Don't believe
a word he says.

Two examples: 30 days to reach Proxima Centuri? BULL****!

No planets are known around Proxima Centuri. More BULL****!

Pick someone with a better education.

Greetings all,

Some questions I have but before that I want to say that I have always had
alot of intellectual curiosity and love history, political science,
religion, philosophy etc. I must say that i have a tremendous respect for
those interested in science as I find it particularly hard to grasp. Kudos
to all of you. Now for the questions which I hope some of you can answer:

1) Since looking into deep space from a telescope is in fact looking back
deep into the past, I presume that at the edges of our visibility these
areas appear more primitive in terms of the formation of galaxies etc? Now
if this is the case, has any astonomer actually witnessed the birth of a
sun (star)?

You could eventually witness the Big Bang itself...if the orbiting telescope
or lunar telescope were powerful enough.


2) For astronauts going into space:

a) The earth's atmosphere is mostly Nitrogen and Oxygen, are astronauts
breathing apparatus 100% oxygen? Is there any harm in breathing in this
high a concentration? Or is it beneficial? Would we all be healthier if
we could breathe in 100% oxygen at all times?

We would be high a kite.


b) In a spacecraft there is always a lack of gravity (in general). Is it
possible to make the interior of a spacecraft equivalent to the gravity
level on earth?

Easy. Just accelerate to a constant level of acceleration, and you will
have gravity toward the floor all the way to your destination.



3. I believe proximy centauri is the closest star to us..4.5 light years
from what i remember. How long would it take our fastest known spacecraft
to reach it?

About thirty days.


Anyone knows if there are any planets orbiting that star?

Lots. We discovered them with the orbiting telescope.



4. I heard the Andromeda galaxy is heading for a collision with the Milky
Way. I thought the big bang implied that everything is expanding away from
everything else. Which is right?

Both. On *average* everything is moving away from everything else.



5. On the periodic table the lightest elements are Hydrogen and Helium. We
they both immediately arise upon the big bang?


Probably, since they are the simplest elements.

How? I know some of the other
elements (nitrogen, oxygen etc) derive from the intense nuclear reactions
within a star, how did they get away from a star..are they spewed forth
form the solar wind?

Look at the nebulae.


Or do they only arise once a supernova happens and a star
explodes?

No. There just aren't enough supernovae for all you see out there.



6. Some people claim there are multiple universes. Is this just conjecture
or is there any evidence for this?

A universe is all that exists. How can there be more than one everything?
