if not, why?

raventekanya, the universe is not the Milkyway, thats our galaxy. and we dont think there are other universes out there since we havent seen all of our own universe. i think you mean galaxies?

Yes.
We have already found "Super-Earths", rocky planets many times more massive than ours. None Jupiter-sized, yet. Planet discoveries are coming in nearly every week, though. Currently over 200 are known, and billions more are likely.
All depends on the materials available and the conditions present. There are limits to how big a planet can grow, depending on mass and rotation (can't be too big and spin too fast, for example), but that leaves a lot of options out there.

It seems rather unlikely. Such a large planet would attract gas very quickly and soon become a gas giant like Jupiter. It is remotely concievable that if the planet were somehow stripped of its atmosphere (for example, being very close to its star so that the star is constantly blowing the atmosphere away, or having passed close to a star and then slingshotted into interstellar space after losing its atmosphere), then perhaps it could exist with a thin enough atmosphere to be called a rocky planet. Hard to say, though, I think at the very least it would be quite improbable.

I cannot see why we could not have a solid planet the size of Jupiter out there in the Universe somewhere. We are only now finding a few of the zillions of planets that could be out in space orbiting distant stars. Many, many new discoveries are still to be made - some in the near future with the special efforts of the Exoplanet searches in progress now.

on one hand yes, for the sheer size of the universe such a planet might exists
on the other hand no, cause planets having with such a high mass would attract more stuff from the disc it would be formed from.
If it has already formed i could imagine that it would get severly peppered by meteroids, for the reason being a perfect attractor for them by its mass.
life as we know it would have a hard time there and i would say if higher forms of life would establish they would be somewhat flatter than they are on earth.
but i bet its much depending how you define earth-like

yes, and the reason i say this is because of the universe. we live in the milky way? correct and scientists have said that there are other universes out there so who is to say there is not a terrestial planet the size of jupiter.

Yes and there are. All the planets that scientists have found on other planetsare bigger than jupiter. They cannot find plantets smaller than Jupiter because it is they don't have the technology.

I call city Elleville, and fairly of having a baseball franchise, I initiate a baseball league for women. it is going to likely be called the famous All-American women professional Baseball League. My megastar alien would be Dotty Henson.

There may be several millions of them.
