Scientists say they have "decisively" overturned the prevailing theory of how planets in our Solar System formed.

The established view is that material violently crashed together to form ever larger clumps until they became worlds.

New results suggest the process was less catastrophic - with matter gently clumping together instead.


Looks a bit pornographic doesnt it OGF???

Re: New theory on big bang!

Just when you think you've got creation of earth and the universe sorted someone comes up with a new theory that means my seventy years of learning was wasted and I'll never get that time back.....
99.9% of the people can't even get to grips with the size of this planet so how can we possibly understand what goes on more than five miles out into space?
I must admit, it's way above my intelligence, and I don't think the human mind was ever equipped to fully understand the workings of the universe, so we give it our best guess...But it will always be a guess!

If someone wanted to keep us humans prisoner here with no possibility of escape, they couldn't have done a better job. Only death can release you from this planet....I think...

Yes, l also struggle to take it in OGF, But l find it so fascinating that
l cant stop trying to learn more all the time, and these days we are
getting so much more info almost every week that is putting our
earlier ideas into question?
You speak of the size of the world, but the world is tiny, just a speck
compared to other objects, probably that is to our benefit as we
would not be who we are if it were otherwise?
Its only since l have got older that l have had time to really think
things through! I suppose that the less physical l become the more
mental l become? HaHa! You can take that two ways!!

1. Think of the planets not on a plane, but sitting atop a bucket with an elastic fabric placed over the top. If you put a billiard ball in the center, the shape of the fabric would actually be curved around the sun conically (but in all directions). If you tried to roll a marble from one side of the fabric covered bucket with the "sun" in it, the marble wouldn't roll straight across, but start circling around the "sun" in in increasingly smaller spirals. This is a good model for the orbits.

The curvature happens because the shape of space with mass is always curved - not planar.

In those early days 5 billion years ago, particles started condensing as they bounced off of each other (slowing, gravitationally pulling together), slowly flattening around in the accretion disk because of the laws of angular momentum. In short, the (mostly) planar shape of the orbits is the result of the massive gravity of the sun and those early particles bouncing off of one another.

Of interest, Pluto is off that plane quite a bit.

2. I think I understand what you are saying here, Donkeyman, is that you are inclined to theorize that the current universe could at some point coalesce back into a singularity (Big Crunch) to such a point that spacetime once again starts anew (Big Bounce). So, so many questions, aren't there!

One of them being how dark matter and energy would play into such a cycle of events - when we don't even know what it is. And then consider the weirdness of the universe in which atoms hadn't formed, nuclei hadn't formed and density was much greater than black holes, but still didn't collapse back on itself! And how could "something" start out with infinite density holding all of space and time? The answer is that it probably didn't. We just don't know.

It's humbling to consider that most of what is out there, we cannot yet perceive.

3. Yes, most of critical changes, including an offset that allowed the universe to form the way it did, after an extremely small fraction of a second in which space and time formed as we like to measure it. Yes, it's still evolving - faster - like raisins in a bread dough that is rising in different directions all at once, while the raisins pretty much stay the same.

Re: New theory on big bang!

There are places on our home globe that we have not explored and don't understand. We don't even know how we work..... it is not surprising that we have a hard time grasping the infinite. I think that our collective estimate of our intelligence is vastly overrated.

I agree Savvy, and our knowledge is based on things we know. There are obviously lots of things we don't know..
Just like a jigsaw puzzle, how can you know what the finished picture is until you have all the pieces?

Re: New theory on big bang!

It has often been said that we know more about the universe than we do of the bottoms of our oceans. Thinking of this I tend to agree. I am in no way scientifically minded regards things beyond our own plant but Will someone ever be able to tell us what was there before the Big Bang?

Re: New theory on big bang!

Some folks just wait, for all the rethinking to be done and dusted.
