The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse. Rom 1:18-20

Existence: Why is the Universe Just Right for us?
by Marcus Chown NewScientist, July 29, 2011

IT HAS been called the Goldilocks paradox. If the strong nuclear force which glues atomic nuclei together were only a few per cent stronger than it is, stars like the sun would exhaust their hydrogen fuel in less than a second. Our sun would have exploded long ago and there would be no life on Earth. If the weak nuclear force were a few per cent weaker, the heavy elements that make up most of our world wouldn’t be here, and neither would you.

If gravity were a little weaker than it is, it would never have been able to crush the core of the sun sufficiently to ignite the nuclear reactions that create sunlight; a little stronger and, again, the sun would have burned all of its fuel billions of years ago. Once again, we could never have arisen.

Such instances of the fine-tuning of the laws of physics seem to abound. Many of the essential parameters of nature – the strengths of fundamental forces and the masses of fundamental particles – seem fixed at values that are “just right” for life to emerge. A whisker either way and we would not be here. It is as if the universe was made for us.

What are we to make of this? One possibility is that the universe was fine-tuned by a supreme being – God. Although many people like this explanation, scientists see no evidence that a supernatural entity is orchestrating the cosmos. (What! See Prior Paragraphs in this article, genuises!…

The known laws of physics can explain the existence of the universe that we observe. To paraphrase astronomer Pierre-Simon Laplace when asked by Napoleon why his book MĂ©canique CĂ©leste did not mention the creator: we have no need of that hypothesis.

Another possibility is that it simply couldn’t be any other way. We find ourselves in a universe ruled by laws compatible with life because, well, how could we not?

This could seem to imply that our existence is an incredible slice of luck – of all the universes that could have existed, we got one capable of supporting intelligent life. But most physicists don’t see it that way.

The most likely explanation for fine-tuning is possibly even more mind-expanding: that our universe is merely one of a vast ensemble of universes, each with different laws of physics. We find ourselves in one with laws suitable for life because, again, how could it be any other way?

The multiverse idea is not without theoretical backing. String theory, our best attempt yet at a theory of everything, predicts at least 10500 universes, each with different laws of physics. To put that number into perspective, there are an estimated 1025 grains of sand in the Sahara desert.

Fine-tuned fallacy

Another possibility is that there is nothing to explain. Some argue that the whole idea of fine-tuning is wrong. One vocal critic is Victor Stenger of the University of Colorado in Boulder, author of The Fallacy of Fine-tuning. His exhibit A concerns one of the pre-eminent examples of fine-tuning, the unlikeliness of the existence of anything other than hydrogen, helium and lithium.

All the heavy elements in your body, including carbon, nitrogen, oxygen and iron, were forged inside distant stars. In 1952, cosmologist Fred Hoyle argued that the existence of these elements depends on a huge cosmic coincidence. One of the key steps to their formation is the “triple alpha” process in which three helium nuclei fuse together to form a carbon-12 nucleus. For this reaction to occur, Hoyle proposed that the energy of the carbon-12 nucleus must be precisely equal to the combined energy of three helium nuclei at the typical temperature inside a red giant star. And so it is.

However, Stenger points out that in 1989 a team at the Technion-Israel Institute of Technology in Haifa showed that, actually, the carbon-12 energy level could have been significantly different and still resulted in the heavy elements required for life.

There are other problems with the fine-tuning argument. One is the fact that examples of fine-tuning are found by taking a single parameter – a force of nature, say, or a subatomic particle mass – and varying it while keeping everything else constant. This seems very unrealistic. The theory of everything, which alas we do not yet possess, is likely to show intimate connections between physical parameters. The effect of varying one may very well be compensated for by variations in another.

Then there is the fact that we only have one example of life to go on, so how can we be so sure that different laws could not give rise to some other living system capable of pondering its own existence?

Strange Portal Connects Earth to Sun –More Evidence of a “Just So” Universe?

Like giant, cosmic chutes between the Earth and sun, magnetic portals open up every eight minutes or so to connect our planet with its host star.

Once the portals open, loads of high-energy particles can travel the 93 million miles (150 million km) through the conduit during its brief opening, space scientists say.

Called a flux transfer event, or FTE, such cosmic connections not only exist but are possibly twice as common as anyone ever imagined, according to space scientists who attended the 2008 Plasma Workshop in Huntsville, Ala., last week.

“Ten years ago I was pretty sure they didn’t exist, but now the evidence is incontrovertible,” said David Sibeck, an astrophysicist at the Goddard Space Flight Center in Maryland.

Dynamic bursts

Researchers have long known that the Earth and sun must be connected. For instance, particles from the sun are constantly whisked away via the solar wind and often follow magnetic field lines that connect the sun’s atmosphere with terra firma. The field lines allow particles to penetrate Earth’s magnetosphere, the magnetic bubble that surrounds our planet.

“We used to think the connection was permanent and that solar wind could trickle into the near-Earth environment anytime the wind was active,” Sibeck said. “We were wrong. The connections are not steady at all. They are often brief, bursty and very dynamic.”

Several speakers at the workshop outlined the formation of a flux transfer event. One idea is that on the side of Earth facing the sun, our magnetic field presses against the sun’s magnetic field. And about every eight minutes, the two fields briefly reconnect, forming a portal through which particles can flow. The portal takes the form of a magnetic cylinder about as wide as Earth.

Sibeck said to think of the FTE as a giant rolling pin that lies flat along the boundary between the Earth’s and sun’s magnetic fields. (He noted the rolling pin would have to be malleable so it could pierce through both magnetic fields while lying flat.)

“These FTEs kind of look like roller pins, and they form as little blob roller pins at the tip of the magnetosphere facing the sun,” Sibeck told “They can’t decide which way they’re going to slide around the Earth, so they grow there into big roller pins and then they take off and sort of spirally roll along [Earth's magnetosphere] like you’re pounding out dough.”

More than one FTE can form at once, he said, and they stay open for about 15 to 20 minutes.

More to learn

In order to measure such FTEs, spacecraft must not only catch them forming but also be on either end of the magnetic structures (either lengthwise or widthwise). In fact, the European Space Agency’s fleet of four Cluster spacecraft and NASA’s five THEMIS probes have flown through and surrounded these cylinders, measuring their dimensions and sensing the particles that shoot through, Sibeck said. While these measurements have nailed down the width of an FTE, the length is still uncertain though one measurement put it at up to five Earth radii. One Earth radius is about 4,000 miles (6,400 kilometers).

Astrophysicist Jimmy Raeder of the University of New Hampshire used those measurements to develop computer simulations of the portals. He found the cylindrical portals tend to form above Earth’s equator and then in December, the FTEs would roll over the North Pole. In July, they roll over the South Pole.

Sibeck thinks the events occur twice as often as previously thought, proposing two types of flux transfer events — active and passive.

When the magnetic cylinders are active, they allow particles to flow through rather easily, forming important conduits of energy for Earth’s magnetosphere, Sibeck said. When passive, the cylinders have more resistance to transiting particles. The internal structure of a passive cylinder makes it tougher for particles and magnetic fields to flow through. Sibeck has calculated the properties of passive FTEs and hopes he and his colleagues will hunt for signs of them in data collected with THEMIS and Cluster.

The space scientists at the workshop still want to figure out why the portals form every eight minutes and how magnetic fields inside the cylinders twist and coil.

Materialists: How Do We Explain Away Mounting Evidence of a “Just So” Universe?

Why Life on Earth Coincides with a Vital Shift in the Makeup of the Universe
Malaysia Sun
Sunday 26th October, 2008

Canberra, Oct 26 : Scientists have come up with an answer to the puzzling question of why life on Earth coincides with a momentous shift in the makeup of the universe.

According to a report by ABC News, research into finding an answer to this mystery was done by Ph.D. student Chas Egan and Charley Lineweaver from Australian National University.

The conundrum has its roots in the way the universe changes as it expands, explained Egan.

Soon after the Big Bang, some 14 billion years ago, most of the energy in the universe was in the form of heat. Later, as the universe cooled and expanded, matter, such as stars and planets, became dominant.

As the expansion continues, it is expected that “dark energy” – a mysterious force that causes the expansion of the universe to accelerate – will become most important.

Over the past 10 years, observations of the universe have shown that the expansion is accelerating, suggesting that the gradual transition from the current matter-dominated phase to the dark-energy era is underway.

“We’re right on the cusp between the matter-dominated and dark energy-dominated epochs,” said Egan.

Astronomers have been puzzled why this shift is happening right now, just when humans are here to observe it.

“When theorists see something like that, that indicates something suspicious. It looks like a coincidence,” said Egan.

Various efforts have been made to explain this coincidence problem over the years, but none of the ideas raised have gained widespread acceptance.

Now, Egan and Lineweaver have taken a pragmatic approach, reasoning that the only time in the history of the universe that it would be possible for us to exist is around now – when stars have been formed, galaxies coalesced and planets have evolved for us to live on.

“It struck us that it’s kind of silly to think that observers could have occurred anywhere during the whole history of the universe,” said Egan.

“If we are tied to terrestrial planets, then we could not possibly have observed the radiation era, and when the universe gets large and diffuse and so on then we could not possible observe that late future either,” he added.

“The results are important for the direction of dark energy research,” Egan said.

“It means we can focus on other problematic aspects of dark energy with some confidence that there is a reasonable explanation for the coincidence problem, regardless of what dark energy turns out to be,” he added.
