Mystery - Guest - 06-06-2009
Huge parts of the universe can be seen,but even more remain hidden.The latest estimate that we can perceive 4 percent of matter and energy,and this is only because some of the light is reflected or emitted by those parts.A whopping 96 percent of the universe is beyond our view because it is not in the visible spectrum.It is undetectable matter.Likewise the universe is known in some small portion by nearly all of us.But we continue to search for answers to great mysteries.Who can estimate the immensity of discovery awaiting us?How much phenomenal energy is available for healing? paul

Astronomers on Mauna Kea are looking into this.... Last months' Astrotalk was on radio imaging... right to your first question!
There are many very interesting programs offered this year (the International Year of Astronomy) Most of it is FREE!
At the University - AstroTalk, usually Thurs or Fri evenings, part of the Astroday - on break for the summer, but check at www.astroday.net for the fall schedule
Imiloa has the directors series, third Saturday night of the month, 7pm: http://www.imiloahawaii.org/events.php
The Onizuka Visitors Center on Mauna Kea has the Universe Tonight series on the 1st Saturday every month at 6pm: http://www.ifa.hawaii.edu/info/vis/saturdayevents.html

About 8 years ago, I read a small article which said there are more stars in the sky than grains of sand on all the beaches and deserts on earth. It gave me a feeling of utter insignificance, and I have never looked at things quite the same again.

Paul24 - there is a huge amount of mass in the universe that we can't see directly, in other words, it doesn't shine. All those images you see from telescopes, including those on Mauna Kea and the Hubble, only show the things that emit light that we can detect. A lot of that light is not something you can detect with your own eye, much of it is emitted at infrared and radio wavelengths and many of the telescopes on Mauna Kea are designed to detect those wavelengths.
Having said that, the observations we make using those wavelengths show that there is still a huge amount of mass in the universe that we can't detect directly, at least we can't right now. That mass is detected by watching its effect on other more visible objects we can see, e.g., stars and galaxies.
It's a weird universe and we're still only starting to understand it. For decades the expansion of the universe was "understood" and a lot of time went into understanding its future. The expansion had to slow down, surely? Now we see that the universe's expansion is accelerating, so cosmologists use "dark energy" to try and explain that (here's an analogy - imagine putting your foot on the brake but instead your car keeps speeding up - it's what we're seeing right now). Even more stuff that we can't explain, at least not easily!
As for relevance to Puna, there are a few people living there who are actively involved in the research. Not me - cosmology baffles the hell out of me, but I do carry out some of the observations.

PS. If you do get the chance it's worth a trip up to the Onizuka Visitor Center, especially in the evening when you can join in the star gazing.
Edited to add at 22:55: Only just now seen Paul24's previous posts, so hope his was a genuine enquiry and not something leading to some universal healing rubbish.

Hi tom thanks for the info and yes i was serious about that.Some of the other posts were for fun.Hope more people respond to this subject even if its not about puna.

Thanks for this one Paul24...how blessed are we in Hawaii to look up into the night sky and be fascinated by how tiny we are in comparison?
My neck always aches the morning after a very clear night sky! LOL

Great topic i also look up and wonder.I do feel lucky to have this view in my backyard.people come from around the world and pay big money to see the stars here,and we live here.
