Genesis mission to the sun: Did it confirm the nebular theory of formation of the solar system?

The Genesis spacecraft mission, launched in August 2001 by NASA, was designed to observe the solar wind, particles coming from the sun, entrap a sample of those particles on substrates and safely return them to Earth. The spacecraft travelled to a point about 1.5 million kilometers (or about 1 million miles) from Earth called Lagrange point, L1, where the gravitational force of the earth is matched by that of the sun. At this location the Genesis spacecraft was well outside of Earth’s atmosphere and magnetic environment, allowing it to collect a ‘pristine’ sample of the solar wind. Genesis’ overall flight path resembled a series of loops (Fig. 1): first it circled five times around L1, called Halo orbit, where it remained for 850 days, then it moved back for a short loop around the opposite Lagrange point, L2, in order to position the spacecraft for a daylight return to Earth.

On board the spacecraft, ions from the solar-wind impacted the collectors at speeds over 200 km/sec and buried themselves in specially-selected materials. These samples were sealed in enclosures for their safe return to Earth in a sample-return capsule (SRC). Then during the return-to-Earth stage something went horribly wrong. On NASA’s Genesis Search for Origins website it is described as follows.1

On 8 September 2004 the SRC entered Earth’s atmosphere as planned, but its gravity switches were oriented incorrectly as the result of a design error and the parachute system failed to deploy. The high-speed wreck compromised the SRC and shattered many of the Genesis collectors.

The samples were scattered and shattered. But all was not lost it seemed.

However, the Genesis Preliminary Examination Team was able to show that, because the solar-wind ions were buried beneath the surface of the collectors, it is possible to detect and quantify elements in the solar-wind.1

Composition of original solar nebula

Thus in March 2005, Johnson Space Center curatorial staff started allocating solar-wind collectors to the international scientific community to see what could be determined from those samples. The purpose was to glean information on the composition of the solar wind, and hence to determine the chemical and isotopic composition of the original solar nebula which it is alleged formed our solar system. See Fig. 2. Continue reading

Why search for life in outer space?

In a recent LA Times news item it was reported that NASA’s Dawn spacecraft mission found life’s building blocks on the dwarf planet Ceres.1  However, the reality is that all that was found are possibly some biochemical molecules, molecules that are pre-cursor molecules to form the more complex chemistry in living cells.

Organic molecules are carbon based molecules and the chemistry of life is a special subset of those but from the spacecraft data no biochemical molecules were identified.  Those would be molecules like carbohydrates, lipids, proteins and nucleic acids.

The news item reports that this new spacecraft

… using its Visible and Infrared Mapping Spectrometer instrument, … has spotted organics lying on the surface.1

That is the only real fact in the report, that organic molecules of some sort have been found on Ceres.

While the scientists aren’t sure exactly what the compounds are, the fingerprint is characteristic of material containing carbon-hydrogen bonds, and may include components like methyl and methylene.(emphasis added)

But they don’t even know what the molecules are, and the research is hyped up in hope that scientists may find life–even just microbes–living on worlds other than our own.

We can now add this dwarf planet Ceres to other ‘space rocks’ that have been so hyped in the past few years in the quest to find life out there in the solar system. Examples are Mars,2 Enceladus (the sixth-largest moon of Saturn),3 Titan (the largest moon of Saturn),4,5 Europa (one of the 4 Galilean moons of Jupiter),6 and the asteroids.7 Continue reading

The movie “Arrival”

arrivalposterRecently I watched the 2016 movie “Arrival“. It depicts the story of the arrival, at twelve separate locations around the earth, of twelve mysterious spacecraft. The key character, a linguistics professor, Louise Banks is seconded by the military to interpret the language of alien visitors.

The movie is based on the short story “Story of Your Life” by Ted Chiang (1998).1 It was directed by Canadian filmmaker Denis Villeneuve and stars Amy Adams, Jeremy Renner and Forest Whitaker.

Here is the trailer from Paramount Pictures:

The 7-foot tall aliens, heptapods,2 which look something like octopuses with 7 tentacles and a human hand, are depicted as enormously technologically advanced on humans. Their 7 tentacles each have 7 tendrils, out of the centre of which they eject an ink-like substance. Remember octopuses produce a black ink like substance. (And you might ask why all the 7’s. It’s science fiction after all.)

Alien language and perception of time

These alien heptapods use a vocal communication that is unpronounceable by humans (classified as Heptapod A), but, as professor Banks discovers, they also have a written script (Heptapod B), which can be dissected and interpreted. But strangely enough the vocal and writing components are unrelated, in the sense that Heptapod B does not represent sound. Heptapod B is written with the ink-like substance they eject from their tendrils and they are able to manipulate it in space to form the characters of Heptapod B.

We are told that a deep understanding of their language can induce a non-linear perception of time in those who learn it. This idea is where it really gets crazy.arrival_2016_heptapod_and_doctor

The story introduces the concept of when one learns a new language, one also learns to think the same way that the producers of that language think–the Sapir-Whorf hypothesis–because one’s brain is rewired to think that way.

Then, with this new perception of time, time-like loops are introduced (really time paradoxes) where, because the professor experiences (in her thoughts or perception) the future, she gets knowledge (of future events) that she then uses to determine the future events she perceives.

The concept here of our perception of time does have some basis in real physics. It is still an open question of why do we remember the past and not the future. That might sound strange to some but most of the laws of physics are time reversible. The Second Law of Thermodynamics, where entropy never decreases in a closed system, but generally increases, is an exception and the primary reason we always perceive the forward arrow of time.

However, for particle physics (including electromagnetism) there is no preference to which way time flows. Physicists call this a symmetry. And in this movie this is highlighted by the name, Hannah, of the yet to be conceived daughter of Prof. Banks, about whom she experiences future memories. The word “HannaH” is a palindrome–a sequence of letters or characters that can be read either forward or backward and produce the same word.

arrival-movie-symbolsHeptapod B is written in a circular way and is palindromic. At least that is what I understood it was intended to be. Looking at one of the alien sentences (on the right) it does not seem to have reversible symmetry, in the structures that form their words (spiky bits that stick out), though, of course, a circle is not linear in one sense as it is represented on a plane.

Of course, this story is just that, a story and total fiction. Nevertheless, it is an entertaining one.  Continue reading

Evidence against the big bang — new video

A new video has been released by Real Science Radio (RSR), and available in DVD, Download, and Blu-ray formats! I recommend you buy and watch it. I made some critical suggestions during its production and find it to be an excellent product. To download it or buy a DVD or Blu-Ray disk click this link RSR’s Evidence Against the Big Bang.

evidence-against-bb-banner-rsrDuring RSR’s on-air debate with Lawrence Krauss, this leading big bang proponent said that, “All evidence overwhelmingly supports the big bang“. So Bob Enyart began assembling a bulleted list of mostly peer-reviewed scientific evidence against the paradigm. That assemblage led to the production of this video RSR’s Evidence Against the Big Bang!

The makers PRODUCT DESCRIPTION is as follows.

Evidence Against the Big Bang – Blu-ray, DVD or Download

When people wonder what evidence exists for the Big Bang, many ask Google. And not surprisingly, when folks search for: evidence against the Big Bang, Google sends most of them on over to Real Science Radio’s List of Evidence Against the Big Bang. Yet this is surprising: When NASA urges you to trust the theory because of its confirmed “predictions”, folks who Google: big bang predictions, also find RSR’s article ranked #1!

This video can help prepare you for the coming revolution in cosmology. The nine pieces of evidence presented herein are bringing people out of the failed science of the 1900s and into the 21st century demanding truth regarding both the origin of universe and ultimately, the origin of ourselves.

And now, let’s leave out the word “predictions” and leave out the word “against”. Increasingly, when scientists and others just Google: big bang evidence, the search engine is sending them on over to RSR’s evidence AGAINST the Big Bang! So whether you are a creationist or even if you’re dug in still defending the old scheme on the origin of the cosmos, you’ll want to watch this video to catch up with the latest amazing science on the big bang!

Antimatter matters for the big bang origin of the Universe

In what physicists have called a “technical tour-de-force”, scientists have for the first time made measurements of how antimatter atoms absorb light.1

Researchers from the ALPHA collaboration team at CERN, the European particle physics laboratory outside Geneva, collected cold antihydrogen atoms in a magnetic “bottle” and irradiated them with an ultraviolet laser to test what frequency of light is needed to excite the antimatter atoms into an excited state. This was done to test to see if antimatter atoms behave the same way as their normal matter counterparts. No discrepancy (a null result) was found with standard theory, which predicts that antihydrogen should have the same energy levels as normal hydrogen.

The null result is still a thrill for researchers who have been working for decades towards antimatter spectroscopy, the study of how light is absorbed and emitted by antimatter. The hope is that this field could provide a new test of a fundamental symmetry of the known laws of physics, called CPT (charge-parity-time) symmetry.

CPT symmetry predicts that energy levels in antimatter and matter should be the same. Even the tiniest violation of this rule would require a serious rethink of the standard model of particle physics.

Warp drive

Gene Roddenberry’s classic sci-fi drama, Star Trek, made famous the warp drive, a theoretical concept whereby a spacecraft travels Faster Than Light (FTL).

I was once told by a ‘trekky’ enthusiast that the warp speeds they describe on the television shows and in the movies, may be calculated as follows. Warp factor w, from the original Star Trek series, means that the spacecraft travels at w3 times the canonical speed of light (c @ 300,000 km/s or 186,000 miles/s).3 Therefore warp factor w = 7 means the spacecraft travels at 73 = 343 c.  It would be unusual to hear that the starship the USS Enterprise (see Fig. 1) had exceeded warp factor 9, which is about 729 times the speed of light.

Figure 1: The starship the USS Enterprise, from the original Star Trek TV series, which could travel faster than light by engaging its warp drive.

To travel even around the local neighbourhood of our galaxy warp factor 9 (from the original TV series) just won’t do it. The nearest star to our solar system is about 4 light-years away. So travelling at warp 9, you would take 2 days to get there. Not too bad but what about to other star systems?

To travel 50 light-years, which is a very small distance in the Galaxy and which includes very few stars—only 64 Sun-like stars—would take you 25 days at this speed. Within a distance of 100 light-years from Earth there are known to be only 512 stars of the same spectral class as our sun1 and very few of those might be candidates for a solar system that could potentially support life.2 So it would be much better to be able to travel 100 light-years quite quickly but that would take you 50 days, nearly 2 months. However in the TV shows they often arrive in just a matter of hours. Continue reading

Why look for a new theory of gravity if the big bang cosmology is correct?

Occasionally we read in the popular press, especially online, that someone has come up with a new theory of gravity. Why is that even necessary if the current theory describing the evolution of the universe is so correct?

The standard ΛCDM big bang cosmology is derived from an application of certain non-biblical boundary conditions to the physics of Einstein’s general relativity theory. But when that was applied to the universe as a whole, two problems developed for the secular model. One is the need to add in dark energy (or the cosmological constant, Λ (Lambda), to Einstein’s field equations) and the other is the need for a significant amount of invisible cold dark matter (CDM).

On the scale of galaxies and even clusters of galaxies Newtonian physics is used as it is the low gravity limit of general relativity. But without the addition of dark matter the resulting theory, using the known density of visible matter in galaxies (see Fig. 1) and clusters, does not match observations. But for more than 40 years now dark matter has been sought in various lab experiments with consistently negative results. This has developed into what is called the dark matter crisis.1

The upper curve shows the speeds of the stars in disk region determined from their visible light and the gasses beyond that determined from radio frequency emissions. The lower curve shows what standard Newtonian physics predicts should be observed. The discrepancy is made up by positing the existence of invisible dark matter. Credit: Wikipedia

Occasionally a claim is made that a theorist has some inkling of what dark matter particles might be but the crisis remains.2 Dark matter particles have been sought without success in the Galaxy using very sensitive detectors deep in underground mines,3 or with the Large Hadron Collider (LHC) over 10 years of experiments looking for the lowest mass stable particle in a theorised class of as-yet-undiscovered supersymmetric particles.4

The observational data from thousands of galaxies together with the negative outcome of all the experiments searching for Dark Matter particles indicate that either something is wrong with the physics we use or that the expected dark matter is much more elusive than supposed, or, indeed, does not, in fact, exist—which gets us back to something being wrong with the physics.
