Scientists are starting to put a few pieces of the puzzle together about how the solar system works, but they are not yet ready to make the big leap into the fact that all planets were born and spit out of the sun into the solar system, and beyond. lol

Within our solar system, an extra giant planet, or possibly
two, might once have accompanied Jupiter, Saturn, Neptune and Uranus.
Computer models showing how our solar system formed suggested the planets once
gravitationally slung one another across space, only settling into their current
orbits over the course of billions of years.
During more than 6,000 simulations of this
planetary scattering phase, planetary scientist David Nesvorny at the Southwest Research
Institute in Boulder, Colo., found that a solar system that began with
four giant planets only had a 2.5 percent chance of leading to the orbits
presently seen now. These systems would be too violent in their youth to end up
resembling ours, most likely resulting in systems that have less than four
giants over time, Nesvorny found.
Instead, a model about 10 times more likely
at matching our current solar system began with five giants, including a now
lost world comparable in mass to Uranus and Neptune. This extra planet may
have been an "ice giant" rich in icy matter just like Uranus and Neptune,
Nesvorny explained.
The computer model allowed Nesvorny to
create a video of the potential extra planet's departure from our solar
system.
When the solar system was about 600 million
years old, it underwent a major period of instability that scattered the giant
planets and smaller worlds, researchers said. Eventually, gravitational
encounters with Jupiter would have flung the mystery world to interstellar space
about 4 billion years ago.
As fantastic as these findings might sound,
a large number of free-floating worlds have recently been discovered in
interstellar space, Nesvorny noted. As such, the ejection of planets from solar
systems might be common.
"The work raises interesting questions about
the early history of the outer solar system," Nesvorny told SPACE.com. "For
example, traditionally, most research was focused on the giant planets, their
satellites, Kuiper belt objects, and their interaction — that's what we have in
the outer solar system now. But how about Mars to super-Earth-size bodies? Have
such objects formed on the outer solar system and were eliminated later? If
not, then why?"
"This is just a beginning," Nesvorny said.
"It will need quite a lot of work to see if there actually was the fifth planet.
I am not fully convinced myself."
Nesvorny's research is detailed online in
the journal Astrophysical Journal Letters.
The scientist that puts up his/her paycheck to make that leap will be in-famous!
ReplyDeleteHmm, maybe you could do the peer review Lou! LOL!
Hey Lou, good to see you back. I have read stories of the planets" battling each other" in the ancient past. This must be where that concept comes from?

Hi Chris, I bet they would love being peered to a ufo nut.
ReplyDeleteHi hoss, I think the scientists are coming from some other angle, an angle that will not jeopardize their paychecks.
ReplyDeleteHi Lou,
ReplyDeleteI to have believed for many years that the solar system was originated the way they told us because it all did look so very logical to me, but that stopped immediately after I saw your eye opening thread about it on ATS.
I never would have thought about that possibility of which I immediately realized as a “non scientist” :lol: that it is in fact an outstanding theory.
And that Dark Fireworks on the Sun NASA video from June 7, 2011 did show in fact how very realistic that theory is.
Because I don’t expect that it will be you that despite you would deserve it will receive the Nobel prize for that marvelous theory which when it eventually will see the light of day out will no doubt will have an earthshaking effect on the whole scientific community and of course the whole world, you and I may perhaps live long enough to see which scientist will then come forward in time with then “his” exactly the same theory and therefore will receive the Nobel prize for it how undeserved that then would be.

Hi space,
ReplyDeleteThat is the way of this paradoxical world. lol
Hi Lou, thanks for answering my friends question about me . I understand what you said and I am comfortable with the answer that you gave her.
ReplyDeleteIts good to know" here" is OK!

Hey Lou, how come you took down the family story?
ReplyDeleteI did not get a chance to finish reading it . Is there another place I can go to finish reading it ?
