Fred, one of my objections to the parallel universe theory(ies) is that most proponents claim the universes split off from each other at every decision point--implying that for every choice you make, there is another universe inwhich you made a different choice. That in turn is a subtle undermining of the whole idea of morality. How can there be right and wrong, sin or righteousness, if everyone makes every possible choice, in some universe? Indeed, this may be the secret appeal the parallel universe theory(ies) has for some people. Anything to get away from the idea of facing judgment by God.
I agree. This is absurd since each of us make a decision about something every 5 seconds. For exemple, you decided to type this reply, what would be our future hadn't you write it? Maybe some genius scientist wouldn't read your idea which could give him inspiration for a new time machine...
I think the law of conservation of matter and energy itself would preclude any parallel universes.
Sort of like historical fiction, right? After all, everything parallels reality, but there are many minute details that are not the same.
This is really interesting information about Pluto: Icy Volcanoes May Erupt on Pluto

And here's more about Pluto.

And her is the official news from the University of Toronto, from a couple weeks ago: Astrophysicists find Jupiter likely bumped giant planet from solar system.

Quote:It’s like something out of an interplanetary chess game. Astrophysicists at the University of Toronto have found that a close encounter with Jupiter about four billion years ago may have resulted in another planet’s ejection from the Solar System altogether.

The existence of a fifth giant gas planet at the time of the Solar System’s formation — in addition to Jupiter, Saturn, Uranus and Neptune that we know of today — was first proposed in 2011. But if it did exist, how did it get pushed out?

The researchers examined the planets' moons and their orbits to create computer simulations
based on the trajectories of Jupiter's Callisto and Saturn's lapetus (pictured). They then
measured the likelihood of each one producing its current orbit in the event that its host planet
was responsible for ejecting the hypothetical planet

More news from the Rosetta mission to comet 67P" Oxygen found in comet challenges solar-system theories

Quote:BERLIN (AP) — Scientists say they have detected significant amounts of molecular oxygen coming out of a comet, an unexpected find that may have implications for the search for alien life and understanding how the solar system formed.

Oxygen atoms are abundant throughout the universe, but because they react very easily with other elements they are rarely found in the molecular form known as O2. Scientists had previously assumed that almost all oxygen in a comet would come in the form of water (H2O), carbon monoxide (CO), or carbon dioxide (CO2).

But using instruments aboard the European spacecraft Rosetta, researchers were able to prove the existence of large amounts of O2 in the gas cloud, or coma, around the comet named 67P/Churyumov-Gerasimenko.

"It is the most surprising discovery we have made so far on 67P, because oxygen was not among the molecules expected in a cometary coma," said Kathrin Altwegg, who co-authored the study published Wednesday in the journal Nature.

Andre Bieler, a research fellow at the University of Michigan who contributed to the study, said the constant level of molecular oxygen observed in the gas cloud indicates it was trapped before the comet formed and has remained there, untouched, since the early days of the solar system some 4.6 billion years ago.

Altwegg said the process by which molecular oxygen got into the comet challenges some theories about how the solar system formed, theories that presume all matter was heated and then cooled. Such a process would have resulted in the loss of molecular oxygen.

She said the finding could also have implications for the hunt for life on other planets. Many scientists have assumed the presence of oxygen and methane is a good indication of life, because those molecules are a by-product of primitive life forms.

But the abundance of both on comet 67P suggests that those two molecules alone shouldn't automatically be taken as evidence of life, said Altwegg.

Sara Seager, a professor of planetary science at the Massachusetts Institute of Technology who wasn't involved in the research, said the findings were a "wake-up call" because O2 has long been top of the list of molecules sought by scientists hoping to find evidence of life on other planets.

"The findings will add fuel to the fire for an already ignited debate about O2's false-positive scenarios," she added.

Why is it so surprising? Earth's atmosphere is full of O2.

Somewhere in the article, or a video, that point was raised. It seems that O2 has always been thought of as not being natural since O2 has this habit of bonding with other elements. As the theory goes, it will be found on planets with life, and are able to convert things like CO2.

This was not expected in the primordial soup.
Mars Will Become a Ringed Planet When Phobos Dies

Quote:Mars’ doomed moon Phobos may leave its parent planet a parting gift. A new study shows the moon is likely to break apart before it hits the atmosphere, creating a debris ring that will encircle Mars for millions of years.
Do you think these pictures are real?
I can't believe for example, that light coming from coiastal towns reflect so much on the ocean bottom...
IMO they are heavily computerized if not totaly made up.

Whole lota' Photoshopping going on there. I suppose adding the light intensity may have made it look unreal.

But my question is with the shot of Japan and Korea. It looks like the tinkerer added greenery to show forestation. It is so fake it makes the two countries look like something from a terrain board.

Incidentally is there a reason for adding all those moving lights in the pictures? I'm curious to know why.
One of the many, many wonderful things about growing up in Alaska, was the time spend in winter gazing at the Auroras coming and going. For those, who never lived near the Arctic Circle, these pictures can't begin to convey the wonder of looking up at the night sky and watching the lights wax and wane before your very eyes.

Chelyabinsk anyone? Remember that one a couple of years ago?

Small Asteroid to Pass Close to Earth March 5

Quote:Asteroid 2013 TX68 is estimated to be about 100 feet (30 meters) in diameter. By comparison, the asteroid that broke up in the atmosphere over Chelyabinsk, Russia, three years ago was approximately 65 feet (20 meters) wide. If an asteroid the size of 2013 TX68 were to enter Earth's atmosphere, it would likely produce an air burst with about twice the energy of the Chelyabinsk event.

The asteroid was discovered by the NASA-funded Catalina Sky Survey on Oct. 6, 2013, as it approached Earth on the nighttime side. After three days of tracking, the asteroid passed into the daytime sky and could no longer be observed. Because it was not tracked for very long, scientists cannot predict its precise orbit around the sun, but they do know that it cannot impact Earth during its flyby next month.

"This asteroid's orbit is quite uncertain, and it will be hard to predict where to look for it," said Chodas. "There is a chance that the asteroid will be picked up by our asteroid search telescopes when it safely flies past us next month, providing us with data to more precisely define its orbit around the sun."
So they were not able to determine its orbit, yet they say they are sure it will not impact earth. They do not know where it is, but yet assure us that we are all going to be safe come March 5, when the asteroid will likely pass "close" to earth.

I've got an idea--lets suggest preferred targets. Here are a few suggestions:

(1) Mecca
(2) The White House
(3) Qom, Iraq (the Iraqi "holy city")
(4) Pyongyang, the capital of North Korea
(5) Medina (second holiest Islamic site)
(6) Hollywood (they've certainly got it coming by now)
(7) Any Planned Parenthood Facility
They don't want us to panic... If they said "we are sure that the asteroid will impact Earth but we don't know where on Earth" then everybody would start to run in all directions.
I believe they have already stated that if it entered the atmosphere, it would blow apart in the atmosphere, like the one over Chelyabinsk, or even Tunguska. Opps, Tunguska would have been a bad one, wouldn't it. S11
The Chelyabinsk meteor fell in a lake. The odds of hitting populated areas is low. But let's see the reactions when that happens.
Quote:Gravitational waves finally detected in massive breakthrough Einstein predicted a century ago

The first direct detection of a gravitational wave by a pair of observatories in the United States will offer science a new way of seeing the universe, a sort of gravitational wave astronomy, physicists say.

Leaders of the LIGO experiment, twin observatories in Louisiana and Washington State, announced Thursday that, back in September, their devices detected a split-second ripple through space-time caused by some distant cosmic cataclysm.

“Until this moment we had our eyes on the sky and we couldn’t hear the music,” said Columbia University astrophysicist Szabolcs Marka, a member of the discovery team. “The skies will never be the same.”

It was the shock wave from the merging of two black holes 1.3 billion years ago, each about 30 times the mass of the Sun, said David Reitze, a physicist and a spokesman for the team.

“What’s really exciting is what comes next,” said Reitze, comparing it to Galileo’s pioneering use of the telescope. “We will also hear things that we never expected, and as we open a new window onto the universe, we may see things we have never seen before.”
