Distant solar system mirrors our own

Planets orbiting a sun-like star exhibit the closest layout to that of our own solar system yet seen.

The system known as 'Kepler 30' contains a trio of planets, the orbits of which align almost exactly along their star's equator. The discovery lends credence to the idea that planets emerge from a flat disc of material encircling their parent star, an idea that had been losing ground due to the number of solar systems being found with skewed orbits.

The planets in Kepler 30 are larger than those in our solar system but not large or close enough to their parent star to be considered 'hot Jupiters'.

"he discovery supports the idea that planets emerge from relatively flat discs of material encircling stars and, at first, orbit neatly in the same plane, just as our eight planets circle the sun."

comparing reaching the speed of sound with reaching the speed of light is not only useless, it's also meaningless. The speed of shockwaves on the surface of our planet is merely a property of our atmosphere, and changes with the local pressure, temperature, composition of the air, etc, so it's not constant even on our planet, and speeds on the surfaces of different planets will be widely different from one another. What it is on our planet is meaningless, it could be anything else, then what. Say if it was 100m/s, we would've reached it long before we did with it being what it is. ... [More]

Not when describing travel at light speed, it is exactly the correct length. Unfortunately we don't get to decide what is possible or not, the universe has already decided that. The laws of physics can not be repealed by mankind. I will add this caveat; although we can not break or change the laws of physics our understanding of them can change. It is possible that relativity may prove to be wrong, or not the whole anser. However it has passed every test so far and hence the best information we have is that any object posseing mass can not reach the speed of light.

I am the last person to insist that what we call science today is going to be the last word. Judging by the just the last few centuries, I wouldn't even hazard a guess about what "science" will mean 500 or 1,000 years from now. I can't imagine.

Science is a methodology, a logical way of discovering and understanding. In that sense science will mean exactly the same as it does now in 500, 1,000 or 10,000 years. What it has discovered and what we understand as a result of science, that no one can imagine.

It's indeed impossible... NOW.

Didn't you post a thread recently about an impossible find becoming possible? Anyway light-speed, I feel confident on breaking that. Especially when I am wearing my Adidas tracksuit.
