Well, i am not sure whether this topic is placed in the right place.

But, i just can't think of another better place to put this.

Ok, so you views and ideas about gravatational waves.

What do ya think?

gravitational just the same as magnet waves exist, its a nuclear force. whats the point of your poll?

Oh. i didn't know that.

Den, when i ask my physics teacher a few months back about gravitational waves, he looked startled as though i was talking some kind of alien language. And i thought maybe it didn't even exist. Cause you know after all he is a physics teacher.

You mean gravitational waves do exist? How can you prove that???

What do you mean it is a nuclear force???

"You mean gravitational waves do exist? How can you prove that???

yes they do.

I dont have to prove it, nature does it for us in the way of tides in our oceans from the moons gravitational force. and so any massive body that oscilates will create gravitational waves. Much in the same way as when you wave a magnet over a pile of paper clips and they move, its a magnetic wave.

A nuclear force as the name suggests is from nulclear particles or Quanta that exert a force on other Quanta. magnetism and gravity are 2 such examples of a nuclear force

I think gene is talking about those gravitational waves that do not yet have any proof of existing. I don't know a lot about them but here is a site on them:

what the hell is a magnetic wave?

gravity and electromagnetism are completely distict from the nuclear forces.(now, under present conditions)

Although, there is a very promising theory that unites Electromagnetism and the nuclear forces, but we are a few GeVs away from being able to test it. But, for all we can prove right now, they are different.

And, GR says that there are gravitational waves, and it appears to be true: http://www.cem.msu.edu/~cem181h/projects/98/TBA/Gravitational%20Waves.htm. And, on an interesting side note, there used to be a class at caltech exclusively about gravitational waves. I don't know if it's still being taught, but I thought it was interesting.

hello...

I asked my teacher what gravitational waves were some time ago...

he said it was something like a transverse wave theough space-time...

em... I'm wondering... can a gravitational wave be a longitudinal wave? pushing the space to and fro?

does that mean they are ripples in space?

Dont always listen to what your physics teachers say. My high school physics teacher says that if the Earth's magnetic field were to dissapear everything would float off the surface of the earth.

thats funny. what happened to gravity?

##### Share on other sites

I've always thought gravitational waves were just theoretical... And if we knew they exist then what was the point of that "Gravity Probe B" that was supposed to test their existence?

##### Share on other sites

Gravity Probe B was deisgned to test whether space time is 'dragged' by the earths cosmic movement...not nessercaily a consequence of gravity waves but an outcome of general relativity no less.

sorry to disturb again... but is the gravitational wave really wave through space?

if so, is it a transverse wave or longitudinal wave? or are there two forms?

thanks
