What observational evidence...?

T Tauri stars have bipolar outflows, to the best of my knowledge.  They form Herbig-Haro Objects when the collide with slower matter from the interstellar medium.  They might not always show up with T Tauri stars because of nearby nebula, but my astronomy professor (James Kaler, UIUC) assures me that they are there.\n\nIf you're talking about mass outflows that the T Tauri stars outputs in addition to the bipolar flows, then I'm sure Doppler shifting can be used.  The speeds for the regular outflows should be pretty similar to that of the T Tauri itself, whereas the bipolar flows (depending on orientation to earth, of course) should be much higher.  I hope this helped!

Greetings,\n\nKinda outta my league, but perhaps the link I posted can be of some use to you.\n\nDiscover had an article last year about a couple of inflation cosmology theorists who believed the speed of light, while constant now, was not constant in the very early universe, it was in fact slower.  Not sure about all that, but thought you might want to go digging for the article.\n\n-matt

A great intergalactic convergance?  A great cosmological simultaneity?\n\nIve noticed that I sometimes track people for a while but then diverge later.  Must be common furrows in the twisted convolutions of our collective brains.  Like passing someone slowly on the freeway.

The only way to really find out is by experiment. I mean, this is the science section, not the philosophy section. Go out and fight something.

Let me tell you a story about anecdotal evidence.  I had this friend who always supported his arguments with anecdotal evidence, and one day I took him to task for it, by presenting him with statistical data that completely demolished his hunches.  :^)

I believe this methodological approach compares data from observation of natural phenomena, rather than controlled experiments, to make a credible claim. It may not be feasible, legal, or ethical to do certain experiments, so you basically have to look at what's happening in nature to infer conclusions. Maybe try looking up 'natural experiment' or 'comparative method?'

First question: none Christians have denied evidence since Galileo and before.\nSecond question: none, because other than an astronomically improbable coincidence, they would be right.\n\nReally if you have faith your logic is biased and always "win/win"

there is no evidence or confirmation

Probably a t-test. \n\nTell us what hypothesis you are testing.

Well, hypothesis is a possible prediction made from your observation.\n\nWish you all the best!

Great idea.  What is your hypothesis?  What experiment will you do?  What data will you collect?  How will you interpret it?

.......and what scientific fact is it?

Well you can never be sure, but one theory is "The Big Bang".  Some useful websites are: \n\n- liftoff.msfc.nasa.gov/academy/universe/b_bang.html\n- www.umich.edu/~gs265/bigbang.htm\n- en.wikipedia.org/wiki/Big_Bang \n\nHave fun!

Do you mean "anecdotal evidence"?

There is good evidence to suggest that the global patterns are shifting abnormally, but there is also good evidence to suggest that the patterns are not shifting abnormally.\n\nAsk again in 20 years and we'll know for sure.  ;)

This comes from the movie "Suspect Zero." It is a 2004 film. I've linked a site about the movie. The above crack about creationism shows a lack of understanding of scientific observationism without bias.

There HAD to be SOME form of evidence.
