Nonsense about Mars from Pakistan's Business Recorder

Business Recorder - Pakistan's biggest financial daily - confirms that little knowledge, when combined with pre-existing religious beliefs, can be a source of a major embarrassment (hat tip to Muhammad Akbar Hussain and Zakir Thaver). This story also upsets me personally as the Business Recorder idiocy is related to astronomy. Okay, I don't want to make you wait any longer. Here is the headline: "Signs of the Day of Judgement: NASA confirms the possibility of sun rising from the West"

So first you notice that the story is about religion - rather than science. Second, there is a clear desire to seek an affirmation of a religious claim from science. Third, the source of authority regarding this lies in the West - in this case (and quite often) NASA (even though there is no mention of NASA in the story itself). Nidhal Guessoum recently attended a whole meeting dedicated to finding science in the Qur'an - and you can read his posts here and here.

But what is this bold claim, in a major newspaper, based upon? Well, as it turns out, it is based upon a gross misunderstanding of how planets of our solar system appear to move in the sky. Muslim astronomers, a thousand years ago, had a better understanding of astronomy than these editors of Business Recorder in the 21st century. Here is the claim:
ARTICLE (April 09 2010): The science of astronomy states that the speed of planet Mars has been decreasing in its course toward the eastern direction in the past few weeks to the level we notice the "waver" between the east and the west and on Wednesday the 30th of July the planet movement stopped going toward the eastern direction.
Then in the months of August and September...Mars changed its course in the opposite direction to the West- and that until the end of September which means the sun will rise now from the west on Mars!! And this weird phenomena of the opposite movement is called "Retrograde Motion" Most scientist state that all the planets will go through the same once at least and our planet Earth is one of them. Planet Earth will move in the opposite direction some day and the sun will rise from the west!!
This might occur soon and we are unaware! The rise of the sun from the west is mentioned in the hadith and this is the major sign of the day of judgement, most if not all, the minor signs have occurred. Wake up. Our beloved messenger Mohamed (Peace Be Upon Him) said: "One of the signs of the hour the sun will rise from the west, where no longer tauba (forgiveness) will be granted"
Where can I go and cry?? Okay. I'm taking a deep breath. Phhooooo.

So the starting point of the claim is correct, but rest is all garbage. Astronomers from antiquity have monitored the motion of planets and the stars. They noticed that planets, such as Mars or Jupiter, appear to move when compared with the background stars. For example, if we look at Mars night after night, we will see it change its location with respect to the background stars. The motion, however, is not constant in speed or in direction. For example, sometimes it may appear to slow down and then over the period of next few nights speed up again. In between, it may also appear to us to change the direction it was moving with respect to the background stars. Please note that it is only our perception with respect to the background that is changing.
Nothing is happening to the orbit of Mars!

This change in appearance is caused by the fact that the Earth is going around the Sun faster than Mars (because it is closer to the Sun). When we catch Mars from behind and then overtake it, it looks as if Mars has changed its direction. This is not so strange. You can see the same thing happen when one car overtakes another car on the road. If the slower car is ahead, you will see it first slow with respect to background trees or buildings, then almost stop - when you are parallel to it, and then you will see it going backwards - when you overtake it. The same happens to our view of the motion of Mars (for more, check out this excellent site for retrograde motion, including some nice and simple visuals. Also see this simple animation).

Now, it is quite straightforward to explain this retrograde motion in a sun-centered solar system. But it was a major challenge for Greeks and then later Muslim astronomers to explain it in the context of an geocentric cosmology. This was the primary reasons for the invention of epicycles - which were eventually discarded in the 16th century.

You must now be wondering this is all well and good. But the Business Recorder goes on to claim that "Most scientist state that all the planets will go through the same once at least and our planet Earth is one of them". Hmm...the first part is technically correct. It happens not once, but every time Earth overtakes Mars, Jupiter, Saturn, etc (or when Venus and Mercury overtakes the Earth), we see retrograde motion of planets. So it happens predictably and relatively frequently. What about the Earth? Well, you'll have to go to another planet to see the Earth do the same thing. For the editors of Business Recorder, I would recommend, Venus.

But Salman, you ask, what about the Sun rising from the West on Mars? Here is Business Recorder unleashing its shock & awe on any kind of reasoning. The appearance of the Sun rising and setting has to do with the rotation of the planet on its axis - and (generally) not the direction of its motion around the Sun. So, even if we accept the lunacy of the original claim, that will still not result in the Sun rising from the West!

To be fair to Business Recorder, many nonsense ideas show up in prestigious newspapers (NYT, couple of years ago, published an opinion piece by an astrologer, Washington Post provides a forum for (yikes!) Deepak Chopra, and the Huffington Post routinely publish New Age nonsense). But this article is a good example of why religion should not be mixed with science. The Business Record editors knew what answer they were looking for (i.e. a confirmation of their version of Islam) and did not even bother to check the validity, or even a remote plausibility, of any of the claims. (And if you hear about another Mars rumor - that Mars will be so close that it will appear to be as big as the Moon - please check out this).

Please please please. Keep religion away from science.

AN interesting site you have here. I dont like to read and run. But I do not have the time to leave a long comment either. BUT, I will come back here and leave a comment this afternoon. Now, I just wanted to say - Nice work :) And I hope u r open to discussions - no not on the one I'm commenting on ...

Nameerah said...

I'm so glad you wrote about this. This article from Business Recorder is being printed and shared here, sadly. I finally have some solid information to counter the claims proposed in this piece.
Thanks!

Salman Hameed said...

Hello Nameerah,

Yes, this Business Recorder article has been picked up by many other sources. I will have another post about it.

Psychaoez said...

nice information you got here. it help me to better understand in loop-to-loop or retrograde motion. And thank also for the video.

I like your explanation in the article. Keep up the good work. :)

This is perhaps the most blatant example I have ever seen of the media screwing up science. Unbelievable. IT remins me of a cartoon you may enjoy -- if you have not already seen it -- at www.phdcomics.com/comics/archive.php?comicid=1174. By the way, I love your blog and have added a link to Irtiqa on my site.

Salman Hameed said...

Thanks for the PhD. comic tip and thanks for the kind words about Irtiqa. You are taking a fascinating route from astronomy and physics to theology (and to be an ordained Baptist minister!). Best wishes.

Rational thinking and Science are defined differently by different people. I have reading Karl Popper recently in which he came out with certain flaws with science. Most of those flaws exist with academic thinkers where certain scientific methods are employed to test hypothesis. Karl Popper generally debates about Hume's problem of induction.

Science and Religion can exist together, until and unless one of the two is proved wrong. In this particular case, evidence was found in support of science and religion had no evidence to support its claim. According to popper, the reasoning must be the opposite, and if any evidence is found against the claim then that claim is invalidated no matter how much evidence is found in support of it.

Hence technically, religion has not been proven wrong, where as only one single evidence is required to prove that the current scientific knowledge is wrong no matter how much evidence is found in support of a claim.

I found another confusing and inaccurate astronomy article on the "International Business Times", which substituted our Moon for the planet Mercury in listing the 8 planets of our solar system!!! Goodness gracious!

"Guests will be able to view all four planets -- Moon, Mars, Saturn, and Venus, which will be clustered together, and with Jupiter, Uranus, and Neptune rising later in the evening, leading to a rare chance to see all eight major planets (including Earth), the planetarium said."

I am so glad I ran across this excellent article... I originally encountered the "NASA Confirms..." article in a Facebook Note posting, and almost died laughing... Just knowing that this was utter nonsense.... Then I began reading the comments associated with the posting and was in awe that so many people had bought into this nonsense... My post was short and sweet... "This post is utter nonsense"... Then I ran across this article which directly rebutts every point of the original post.... KUDOS for posting this... Alas, I can sleep well, the Sun is not going to creep into my Western Bedroom window anytime soon.

Keep religion away from science.Yes i think is the good suggestion because until know its hard to know that what is the religion and that fundamentals but every scientist have a religion. Any how i am so glad that i read this article.

Thank you for this website Salman. Its great to finally see a rational, level-headed Muslim blog out there. You give me hope in our future.

Soooo confused. Help!

I thought we always say 'good morning' because a fireball appearing from the east is due to the revolution of our earth, rather than rotation. Only an external force/influence or internal change/disturbance in magnetic flux can change the revolution of the body, but it has nothing to do with the retrograde motion.

reza said...

so NASA confirms the possibility of sun rising from the West its real or fake ? because I see so many people share the news about this on facebook, I'm afraid if this is not true it will mislead Muslims

Irtiqa... time will teach us which is the truth. you are I may not be alive to see that happening... but it is going to happen one day. ofcourse you also be one of them to witness that during the judgement day!! wake up!!

I've seen the sun rise in the west. So have a few million others. You can too. All you have to do, is board a jet taking off from (say) Seattle, soon after sunset, and fly north, in midsummer. It's dark when you take off, but as soon as you are inside the Arctic circle, it's light again. The sun has reappeared above the (north-ish) western horizon. Is this a sign of the end-times? Bwooooha-ha-haaaaa!

why do i sense such an intensified feeling of insecurity within you and for what??
i cant endorse the article since i do not have the relevant research to make a claim however i would like to nicely bullet this through your mind that science and religion NEEDS to be reconciled at all costs, it needs to be linked up it needs to be related it needs to be matched. Good Reason? This will either strengthen the beliefs if the religion is proven correct or will expose the fallacies if there is any within the religion. Second, if business recorder has posted a claim that doesn't feed logic, it is purely their mistake in committing their to duty to research first, ISLAM is not to be blamed. Got that right?
I ask who exactly are you to say that science and religion shall not be linked up? just because people make mistakes in following something good, better or best doesnt mean that you should throw that something away instead of teaching people how not to make mistakes. Man i say you are a complete failure if appointed as a manager of a declining company. You would so want to ask the directors to just shut it off instead of taking corrective actions. a big LOLX for you :)
I dare you to post my comment ;)
