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, what about gravitational waves. I read an article about it but hardly understood it.

 

Ok, so you views and ideas about gravatational waves.

 

What do ya think?

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???

yes they do.

 

I don`t 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, it`s 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 :)

what the hell is a magnetic wave?

 

gravity and electromagnetism are completely distict from the nuclear forces.(now' date=' under present conditions)[/quote']

 

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?
