Sample Horoscope

One day, I went down the aisles of my grade 10 science class asking the kids their birthdays. Each was given the appropriate horoscope. Here's Aries:

Aries – March 21- April 19

You have had some difficulties in the recent past. Sometimes you wonder who your best friends are, or will be in the future.

Someone's words will take on a tone of intensity for you now. Don't fall into a dark, brooding mood as a result. It's good to clear the air, and time to break your silence.

There's high drama on your schedule for the next couple of days, so prepare yourself. That's not necessarily a bad thing. Still, you might want to warn your close friends.

Some encounters will be a very significant -- some more pleasantly so than others. Think of it this way -- you have a choice about how to use this energy, so use it to its best ends.

You're in the mood to catch up on the latest scoop, but your family and friends have been a little too intense for your tastes -- at the moment, anyway. Let them talk, and just listen closely. Your turn will be coming up soon.

I asked the kids to put up their hand if they felt the horoscope was accurate. Hands went up around the room. Then I had them pass it to the person beside them. They started to laugh because all the horoscopes were the same. (I made it up.) It's so easy to persuade people of the truth of something so loony (luney?) as astrology. And easy to demonstrate how false it is. Still, few believers can ever be persuaded otherwise.

BTW: Not a single person pointed out that in the second paragraph I advised them to speak out, but in the last paragraph to just listen.

Standard Accepted Knowledge

In my last article I commented on the differences in positions held by scientists and non-scientists on whether Earth had been visited in the past by intelligent extraterrestrials. I use the term scientists widely, not referring to an occupation but to a state of mind.

No matter what your occupation, I call you a scientist if you look for answers by studying the evidence; if you test to see if proposed explanations work; and if you assume that there are reasonable, physical explanations first, before resorting to magic or far-out justifications for an extraordinary claim.

I made a statement that there is near universal agreement among scientists on the big issues. Here is a list of what I consider those issues to be.

Earth is a speck in the cosmos. There are likely to be many small, rocky planets orbiting stars, some of which will be similar to our sun. There are so many stars, there are bound to me many Earth-like planets at suitable distances from their sun that conditions were similar to those on early Earth.

Earth is old and changing. Continents drift around and collide. Mountains rise. Rivers cut canyons. Lakes and oceans fill up with debris that eventually becomes sedimentary rock. As you dig down through layers you reach older and older rock.

Life processes follow the laws of chemistry and physics. There is no process that requires “magic”. We don’t know all the processes, but are confident that they are “knowable”. (Consider the opposite. If, for example, some magical process causes the heart to beat, then we might as well stop trying to understand how the heart works!)

Life evolves. Little changes in short periods add up to bigger changes over long periods.

The laws of mathematics and physics apply everywhere. The formula for a circle and value of pi is the same on Mars. Magicians don’t do true magic: they are still constrained by the laws of physics. (While watching a magic show, everytime you ask yourself, “How did he do that?” you are applying this concept. You feel that there was a physical explanation, a “trick”. You didn’t see true magic.)

Matter is particulate. Substances are made of atoms that join to become molecules. (Atoms themselves are made of particles.)

The properties an object possesses depend on the observer. (This claim, for which there is much evidence, arises from relativity and quantum physics. Relativity deals with the big concepts of time, space, gravity, matter and energy; quantum physics with the behaviour of matter and energy at the tiniest level.

I might as well mention the fringe items, too.

There are no ghosts, werewolves, vampires, living dead, mammoth spiders, King Kongs, Spidermen, invisible people, extraterrestrial aliens living amongst us.

Astrology is false.

There is no such thing as psychic ability. You can’t move objects by though alone. No one can actually read minds, see the future (rather than predict likelihoods), perceive present, past, or future events by other than the five senses.

Men HAVE landed on the moon (i.e. the landing in 1969 was not a hoax.)
Humans and dinosaurs did not inhabit the Earth at the same time.

I expect many to disagree with me on many of this last list. In particular, countless people will cite amazing occurrences, coincidences, anecdotes, and “facts”. I will leave it as this: I have seen no repeatable, non-controversial evidence that convinces me that, for example, ESP exists. A million dollar prize is available for ANY purported psychic who can demonstrate ANY psychic ability. No one has yet been able to do it.

As much as we, scientists included, might wish for exceptional abilities, extraordinary creatures, and assistance from the stars, there is just no good evidence for any of it.

On Astrology
I notice in my Blog profile, my sign of the zodiac is listed. I regret this, but it comes with the territory.

I would rather not have my sign showing, for the simple reason that it reinforces the fraud/delusion/hoax that is astrology. You may say, “Come on, it’s just for fun. Nobody expects that the little reference to astrological sign will have any significant effect.” Try saying something similar to Big Tobacco, which pays hundreds of thousands of dollars to have a star smoke a cigarette once in a picture, just an incidental smoke. Tiny references add up.

Astrology, horoscopes, signs…the whole thing is of course demonstrably false. Experiments show that the location of Mars, say, in the sky when you were born has zero effect on whether you will lose your wallet today or marry a tall, dark stranger tomorrow. Same with the Sun. And to top it off, the dates are wrong. I’m supposed to be a Virgo, meaning that the Sun was in Virgo when I was wrong. Well, it wasn’t. ALL the dates are wrong. Yours, too. That means you have been reading the wrong horoscope in the newspaper all your life. You’ve been waiting for, or avoiding (they cover themselves by giving two options) the wrong person all this time!

Seriously, the fact that so many people accept astrology (and ghosts, ESP, werewolves, psychic fairs, etc.) as valid is disconcerting to me…especially as I am a physics teacher. Carl Sagan said “Extraordinary claims require extraordinary evidence before they should be accepted.” I find it unfortunate that so many people accept stuff for which there is no evidence or even evidence to the contrary.

Pertinent quotes on this subject:
Sagan – “Don’t be so open-minded that your brains fall out.”
Person sitting before a “psychic”, after being asked his name, “Why do you need to ask?”
Me: Did ANYBODY forecast 9-11? (Answer: no.)
