Jupiter May Have Destroyed Early Planets And Paved The Way For Earth

NASAs Kepler spacecraft has, to date, enabled astronomers to discover over 1,000 planets outside of our solar system. But theres a funny thing about the solar systems astronomers discovered they dont look much like ours at all. Most of them have larger, super-Earths planets smaller than Neptune but bigger than Earth located very close to the Sun.

Our solar system, by contrast, doesnt. Why?

Research conducted by astronomer Gregory Laughlin and astronomer/Forbes 30 Under 30 list member Konstantin Batygin suggest that the responsibility may lie with the planets Jupiter and Saturn.

In a paper published this week in the Proceedings of the National Academy of Sciences, the two astronomers suggest that in the early life of the solar system, Jupiter traveled much closer to the Sun than it is now close to 140 million miles away before reversing course and finding itself in its present orbit about 483 million miles from the Sun thanks to its gravitational interaction between the two gas giants.

Given Jupiters massive size, its strong gravity may have taken its toll on any super-Earths that existed in the early years of the Solar System by literally shifting their orbits so that they fell into the Sun.

In this scenario, the Solar Systems terrestrial planets formed from gas-starved mass-depleted debris that remained, the authors wrote in the paper.

All of this fits beautifully with other recent developments in understanding how the solar system evolved, while filling in some gaps, Batygin said in a statement.

The idea that Jupiter and Saturn once traveled closer to the Sun isnt original to this paper. Called the Grand Tack scenario, it was developed in part by a research group in 2001 and later revived again in 2011 to explain some of what astronomers were learning about the early Solar System. (Astronomer Kevin Walsh has a great page of resources about this theory that you can explore here.) For this research, Laughlin & Batygin ran computer simultations involving the Grand Tack scenario to see how it would impact the Solar System if, like most Solar Systems outside of ours, super-Earths had formed near the Sun.

Its the same thing we worry about if satellites were to be destroyed in low-Earth orbit. Their fragments would start smashing into other satellites and youd risk a chain reaction of collisions. Our work indicates that Jupiter would have created just such a collisional cascade in the inner solar system, Laughlin explained in a press release.

Latest Business Trends for Leaders

Posted: at 5:40 am

Phoenix, AZ (PRWEB) March 24, 2015

Global futurist Jack Uldrich has made a career out of helping leading organizations future-proof themselves, and he loves doing it. "The futurist's job is to focus on the big picture and point out the 800-pound gorillas that others are missing because their attention is focused elsewhere," says Uldrich. "I want to help future-proof as many businesses as I can against all of the changes that are coming tomorrow. Business models are changing daily, while others are fading away completely, so it's important as a futurist to help the organizations I work with to be aware of their blind spots."

The days that Uldrich isnt busy traveling the country speaking on future-proofing, unlearning and top tech trends, he spends researching and 'seeing' what the latest changes in technology may be and then writes on those trends. Uldrich is the author is of over 11 books, his most recent book is "Foresight 20/20."

Uldrichs keynotes are thought provoking, motivating and incredibly easy to digest and relate to. His next engagement is today at the 2015 Innovation Leadership Summit in Scottsdale. Uldrich's other keynotes have included PIMA, ABB/Thomas & Betts Emax 2 product launches, Verizon Wireless Connected Technology Tour, and Emersons Global Community Exchange.

Uldrich's approach to future-proofing businesses is all about taking the blinders off and taking on the Big AHA which is Uldrichs acronym for Awareness, Humility and Action. According to Uldrich, Many potential and upcoming innovations are already foreseeable given today's capabilities and tools. What's needed to reveal them is awareness and the humility to give up stuck-in-a-rut thinking patterns that stifle useful questions and possibilities. Then, a course of action can turn these desired futures into new realities.

Easier said than done but Uldrich plans to forge ahead and future-proof as many businesses as he can. Following his keynote for the 2015 Innovation Leadership Summit, Uldrich will speak with a leading pharmaceuticals firm in New York and deliver the keynote address for the 2015 Expo for the International Card Manufacturers Association in Phoenix on March 30th.

Parties interested in learning more about Uldrich, his writing or speaking availability are encouraged to go to his website. Media wishing to interview him or to learn more about the event can contact Amy Tomczyk at (612) 343-0060.

Battle flag at center of Supreme Court free speech case

Posted: at 9:56 pm

WASHINGTON Texas commemorates the Confederacy in many ways, from an annual celebration of Confederate Heroes Day each January to monuments on the grounds of the state Capitol in Austin. Among the memorials is one that has stood for more than a century, bearing an image of the Confederate battle flag etched in marble.

But you're out of luck if you want to put that flag on your license plate. Texas says that would be offensive.

Now the Supreme Court will decide whether the state can refuse to issue a license plate featuring the battle flag without violating the free-speech rights of Texans who want one. The justices hear arguments Monday in a challenge brought by the Texas division of the Sons of Confederate Veterans.

The group sued over the state's decision not to authorize its proposed license plate with its logo bearing the battle flag, similar to plates issued by eight other states that were members of the Confederacy and Maryland.

The First Amendment dispute has brought together some unlikely allies, including the American Civil Liberties Union, anti-abortion groups, Americans United for Separation of Church and State, civil libertarian Nat Hentoff and conservative satirist P.J. O'Rourke.

"In a free society, offensive speech should not just be tolerated, its regular presence should be celebrated as a symbol of democratic health however odorous the products of a democracy may be," Hentoff, O'Rourke and others said in a brief backing the group.

Specialty plates are moneymakers for states, and Texas offers more than 350 varieties that took in $17.6 million last year, according to the state Department of Motor Vehicles. Nearly 877,000 vehicles among more than 19 million cars, pickup trucks and motorcycles registered in Texas carry a specialty plate, the department said.

They bear messages that include "Choose Life," ''God Bless Texas" and "Fight Terrorism," as well as others in support of Dr. Pepper, burrito and burger chains, Boy Scouts, Mothers Against Drunk Driving, blood donations, professional sports teams and colleges.

A state motor vehicle board rejected the Sons of Confederate Veterans application because of concerns it would offend many Texans who believe the flag is a racially charged symbol of repression. On the same day, the board approved a plate honoring the nation's first black Army units, the Buffalo Soldiers, despite objections from Native Americans over the units' roles in fighting Indian tribes in the West in the late 1800s.

"There are a lot of competing racial and ethnic concerns, and Texas doesn't necessarily handle them any way but awkwardly sometimes," said Lynne Rambo, a professor at the Texas A&M University School of Law in Fort Worth.

Confederate flag license plate battle reaches U.S. Supreme Court

Posted: at 9:56 pm

The U.S. Supreme Court on Monday takes up a free speech case on whether Texas was wrong in rejecting a specialty vehicle license plate displaying the Confederate flag - to some an emblem of Southern pride and to others a symbol of racism.

The nine justices will hear a one-hour oral argument in a case that raises the issue of how states can allow or reject politically divisive messages on license plates without violating free speech rights. States can generate revenue by allowing outside groups to propose specialty license plates that people then pay a fee to put on their vehicle.

The group Sons of Confederate Veterans says its aim is to preserve the "history and legacy" of soldiers who fought for the pro-slavery Confederacy in the U.S. Civil War. Its proposed design featured a Confederate battle flag surrounded by the words "Sons of Confederate Veterans 1896." The flag is a blue cross inlaid with white stars over a red background.

The group's Texas chapter said its members' free speech rights were violated when the state rejected the plate. Several other states have approved similar plates.

When Texas rejected the proposal in 2010, the state said it had received public comments that suggested "many members of the general public find the design offensive" in large part due to the Confederacy being synonymous with the institution of slavery.

A black Texas Democratic state senator, Royce West, said in 2011, "Ill-intended or not, why would African Americans want to be reminded of a legalized system of involuntary servitude, dehumanization, rape and mass murder?"

The New Orleans-based 5th U.S. Circuit Court of Appeals ruled that Texas officials did not have grounds to reject the plate, prompting the state to seek high court review.

The legal issue is in part whether messages on state-issued license plates represent speech by the government or an endorsement of a private message. If determined to be private speech, the state's rejection could violate the U.S. Constitution's First Amendment free speech guarantee.

Steven Shapiro, legal director of the American Civil Liberties Union, which backs the Sons of Confederate Veterans, said although the flag "served as a banner for those who supported slavery and segregation ... Texas cannot pick and choose the plates it approves on ideological grounds."

A ruling is expected by the end of June.
