Wow! mystery signal from space finally explained

Forty years ago a signal–called the Wow! signal–was obtained from space. Some speculated that it might be from an intelligent alien source. Read Wow! Communications from little green men?

Now it is argued that that it was not from little green men, but from a comet. Such is the hype around detection of a signal from aliens that common sense is ignored. Well, time, real science and cool heads have won out. The original source has been found.

The comets, P/2008 Y2(Gibbs) and 266/P Christensen, which were not known back 40 years ago when the Wow! Signal was first obtained, appeared again in the night sky from November 2016 through February of 2017.

An online news site reports from the astronomy team.1

The team reports that radio signals from 266/P Christensen matched those from the Wow! Signal 40 years ago. To verify their results, they tested readings from three other comets, as well, and found similar results. The researchers acknowledge that they cannot say with certainty that the Wow! signal was generated by 266/P Christensen, but they can say with relative assurance that it was generated by a comet.

A new Little Ice Age is predicted for 2030

Diminishing solar activity may bring new Ice Age by 2030! This is the headline of the press release from the Lomonosov Moscow State University published online 17 July 2015.1

The arrival of intense cold similar to the one that raged during the “Little Ice Age”, which froze the world during the 17th century and in the beginning of the 18th century, is expected in the years 2030—2040.1

This is the conclusion of research presented at the National Astronomy Meeting in Llandudno in Wales, by Professor V. Zharkova (Northumbria University) and a team of other well qualified scientists.

The sun has its own magnetic field, which varies in both amplitude and spatial configuration over time. The changes in the strength of the magnetic fields in the solar atmosphere results in changes of electromagnetic radiation from the sun, changes of the intensity of plasma flows coming to Earth, as well as the number of sunspots appearing in the photosphere (the visible lowest layer of the atmosphere which might be called the surface of the sun). They studied the changes in sunspot number, with a cyclic structure varying approximately every 11 years, which also has an impact on Earth’s environment. Continue reading

New planet discovered hotter than most stars

Astronomers from Ohio State University and Vanderbilt University have discovered a planet with a surface temperature hotter than most stars. The planet KELT-9b has a surface temperature of 4600 K, only 1200 degrees K (about 2000 degrees F) cooler than the sun. The planet must have a warm yellow glow.

The astronomy team presented their results in the journal Nature and at a presentation at the American Astronomical Society spring meeting (2017). They found the planet, which is 2.8 times more massive than Jupiter, but only as half as dense, to be continually bombarded by stellar radiation from the nearby star. As a result its day side is so hot that molecules such as water, carbon dioxide, and methane can’t form there. It is not known what the night side is like. It is speculated that molecules may be able to form there, but probably only temporarily. The planet is tidally locked to the central star KELT-9, which, at least, shields the night side from the intense radiation.

The environment of this planet is a far cry from the ideal environment God has created for life on Earth. Certainly life as we know it could not exist on a planet such as KELT-9. And considering that its atmosphere is constantly blasted with high levels of ultraviolet radiation it is unlikely a place to find any sort of life.

Synopsis: A biblical creationist cosmogony (Japanese translation)

The starlight-travel-time problem has been a difficult issue for biblical creationists for a long time. Big Bang cosmologists also have their own starlight-travel-time problem but creationists have proposed various solutions to this problem in the past decade or more. Recently I proposed an expansion on a solution, first proposed by Jason Lisle, in an article entitled “A biblical creationist cosmogony.” It is somewhat technical so I thought I’d write a very short layman summary here.

星の光が届く時間の問題は、聖書的創造論者にとって長い間難題でした。ビッグバン宇宙論者にとってもやはり星の光が届く時間は難題となっています。しかし創造論者は、過去数十年にわたって、この難題に対する答をいく通りか提案してきました。近年私が提案しているのは、最初にジェーソン・ライルが提案した論文「聖書的創造論者の宇宙論」を発展させたものです。これは多少専門的なので、一般向けにこれを説明しようと考えました。

創造主が、創世記1章に記されている順序通りにご自身がすべてを創造したなら、そこに記されているすべての出来事は、その示す通りに約6000年前に24時間を1日とする連続した6日間で起こったはずです。ライルは、これらの出来事(星の創造)は光が最初に地球に到達した時点、あるいは、仮に地上に観測者がいた場合にその観測者が光を最初に目にした時点で起こったと提案しました。その要点は、星や銀河の創造で、ある光は100億光年以上もの距離から到達したというものです。もし私たちが観測者の視点(どう見えるか)のみを考慮するなら、これらの銀河やすべての星の光が最初に届いたのは、創造の第4日のどこかの時点です。

もし、光の速度は一定(c)であるという視点からこれを見れば、光は1年で1光年の距離を進むので、遠い星の光は100億年以上もかけて地球に到達したということになります。したがって、この視点から宇宙を考えるなら、すべての銀河は創造主が創造の第1日に地球を創造するはるか前に造られたということになります。しかし、これも単に観測者の視点(どう見えるか)の問題なのです。「光の速度は一定(c)である」という仮定は、(始点と終点にある)複数の時計の時刻が一致していることを想定しています。私たちは同様に、これとは別の想定、すべての出来事は観測者が目撃した時点で起こったとする想定を選ぶことができるのです。そうすると、「新しく」造られた星々や銀河の光が、創造の第4日に地球に到達したのです。それは、本当にこれらの銀河が造られた時に発せられた最初の光です。 Continue reading

Lecture: A biblical creationist cosmogony in Japan

An illustrated lecture I presented on March 19th, 2017, at Saidaiji Christian Church in Okayama, Japan. It was translated into Japanese by Mr Toru Yasui. The lecture covers the issue of the need to assume a worldview before we can interpret any observational data from the cosmos. Two worldviews are contrasted: The biblical creation worldview and the pagan big bang worldview. Biblical creation cosmogonies are explained and how they provide an answer to how we see distant starlight, from galaxies billions of light-years distant, in a 6000 year old universe. Running time 1 hour 14 minutes.

More on our eternal universe

Journal of Creation Volume 31 Issue 1 2017

In Our eternal universe I laid out the biblical and scientific case for an eternal created universe sustained by the Creator.  That article was published in the Journal of Creation 30(3):104–109, December 2016, which has a wider readership than here, my personal web/blog site. And it attracted some comments via Letters to the Editor.

The ‘standard’ biblical creationist view has been that at the New Heaven and New Earth stage at some point in the future God wipes out the whole starry heavens and recreates a new universe of stars and galaxies. I am convinced the Creator will renovate the earth and its atmospheric heavens in that event but what do the scriptures really tell us?

Below I reproduce the letters arguing against my hypothesis and my responses.

Letter I

J. Creation 31(1) page 41 and page 42

Letter II

J. Creation 31(1) page 43 and page 44

After you have read both sides of the debate I welcome your comments below.

A world without WIMPs

There was talk over lunch and coffee of dark forces, dark photons, and dark neutrons.1 (emphasis added)

This is the extent of what is actually known about dark matter and any other entities from the dark sector of particle physics.  At a workshop where more than 100 physicists took over the University of Maryland, titled “US Cosmic Visions: New Ideas in Dark Matter,” attendees were encouraged to think more broadly to solve the vexing problem of the non-detection of dark matter particles in all experiments that have ever been tried for the last 40 years, at least.

They spoke of axions and other dark-matter candidates so lightweight that they would be detected as waves, and of particles so heavy that they would clump together and encounter Earth only occasionally as a vast invisible glob.1

Despite impressive sensitivity, dark-matter detection experiments such as Large Underground Xenon (detector array above) have not found any evidence of WIMPs. Credit: C. H. Faham/LUX

A recalibration for the dark-matter community

For decades physicists have been fixated on the putative WIMP, a Weakly Interacting Massive Particle, which allegedly has a tendency to intermittently mingle with ordinary matter via the weak force. WIMPs have been alleged to inhabit our part of the Galaxy but all experiments, like the Large Underground Xenon (LUX) detector array, have failed to find any trace of their existence.  Theorists developed ideas that WIMPs might be the lowest mass yet stable supersymmetric particle, called the neutralino but experimentalists with vast, exquisitely sensitive underground detectors such as the LUX array or using the powerful particle accelerator the Large Hadron Collider (LHC) found no such particles though they were meant to be constantly streaming stealthily through our planet. Now, Continue reading
