There's a rumor that on the 17th of October, the sun will rise continuously for 36 hours. I can't see any astronomical or scientific reason that this could possibly happen unless the Earth stops rotating on its axis for three days - there will be daytime for 3 days on one side of the planet and nighttime on the other side.

The rumor is based on emails and text messages received by people around the globe, though some abruptly dismiss it as prank message, others choose to think about it and decided to wait for that particular date - October 17, 2008.

The about,com site did some research about the message and traced that it originates in India by some prankters.

On Oct. 17 the Sun Will Rise Continuously for 36 Hours

Description: Internet rumor
Circulating since: Aug. 2008
Status: False

Summary: Baseless online rumor claims "the sun will rise continuously for 36 hours" on October 17, 2008, turning three regular days into "two big days" -- an event which supposedly only happens once every 2,400 years.

FW: Sun will rise continuously for 36hrs (1.5 days) Coming October 17, 2008 the sun will rise continuously for 36 hrs (1.5 days). During this time the US countries will be dark for 1.5 days. It will convert 3 days into 2 big days. It will happen once in 2400 yrs. We're very lucky to see this. Forward it to all ur frenz

Comments: Poppycock. Let's begin by applying some grade-school science to dispel the ridiculous notion that the sun even could "rise continuously for 36 hours."

The reason we perceive the sun as "rising" or "setting" every 24 hours is because the earth rotates on its axis while revolving around the sun. It does not -- and cannot -- stop rotating, nor does its speed appreciably fluctuate (various factors such as climate and seismic events can cause miniscule changes in the earth's rotation speed, but according to scientists all of these combined add up to a differential of no more than one second per year).

In order for a day to last 36 hours, the earth's rotation would either have to cease altogether or slow down dramatically -- neither of which ever happens, let alone once every 2,400 years. It's physically impossible.

But you knew that, right? What you're really wondering is where this strange idea came from.

Obscure origins of an absurd prediction

Based on the available info (of which there is very little, admittedly), my best guess is that it began as a prank, pure and simple; that it originated in India; and that the perpetrator(s) of the hoax put a great deal of effort into disseminating it.

Here's what I've been able to establish:

• During a one-month period from mid-August to mid-September 2008, over 15,000 postings containing the phrase "the sun will rise continuously for 36 hours" appeared on the Internet.



• Nearly all of these postings contained precisely the same wording.



• Nearly all of these postings originated from India.



• As far as I can tell, not a single word about a October 17 being a 36-hour day appeared in any source, online or off, prior to August 2008.
