Hello All:

My name is Donna, I'm new here and trying to absorb a great deal all at once!

I think Einstein@home is a brilliant concept and I hope for its continued success.

In the meantime, I have some questions that I hope some of you may be able to answer...

1)Is there enough data collected at this point to indicate, approximately, how many gravity waves are detected per day (an average)?

2a)How many of the detected gravity waves have a direct impact on earth? b)What if any disruptions do gravity waves cause, with respect to our planet? Example: studies have been done which seem to indicate that cosmic rays impact climate, volcanics and seismic activity...

3)Is there a system in place which assigns a designated measure, in terms of the size or force of these gravity waves, example: in gamma ray burst detection there are short bursts and long bursts and also there's a distinction in terms of brightness...

4)There is some evidence which suggests a relationship between cosmic rays and gamma ray bursts. There is also a theory that gravity waves could be connected to these other extra-terrestrial events as well... Example: On September 11, 2005, at the height of some record breaking solar activity (inluding a mega solar flare, followed by nine X-class flares and several M-class flares), the Moscow Neutron Monitor experienced a major downward spike indicating a significant cosmic ray event, at the same time, Sonoma's real time gamma ray monitor registered eight back to back gamma ray bursts (later reduced to one long burst with multiple peaks by NASA's SWIFT Project team)Obviously, there must be a connection between these events. I'm curious to know if there were any significant gravity waves detected at the same time (or before or after)...

5)Are gravity waves a source for radiation? If so, how would this be measured or are we not there yet?

If anyone can offer me some assistance in answering these questions, I would very much appreciate it!

Cheers-Donna

I think no gravitational wave has ever been detected with certainty although in the sixties Joseph Weber at the University of Maryland has published an article titled "Evidence for discovery of gravitational radiation".using very massive aluminium cylinders as detectors.The fact is that they are very weak and looking for them is close to looking for a needle in a haystack.

Hello Tullio:

Thank you very much for your informed reply...

So, I am Italian also, half anyway. My Italian side comes from Montella (my grandfather was Destefano), then I married/divorced a Sicilian and became a Volatile!

Anyway, nice to meet you Tullio and thank you again.

Kind regards-Donna
