The star Betelgeuse is doing something. Something important. No one is sure what it means, but it has our attention and we want to keep our telescopes focused on it. Except that this Summer, we can’t.

What’s next for Betelgeuse? [NOTE: Image distorted by minor camera movement.]

Whatever is happening with the soon-to-be supernova Betelgeuse currently, it is critical astronomers and astrophysicists maintain close observation of the progenitor star. It may be decades, centuries, or millennia before it collapses and explodes into a spectacular show for our planet nestled some 640 lightyears away, and yet, at this moment, it is displaying behavior that may give us the first opportunity to learn what a supernova does before it does its supernova thing.

Betelgeuse and its parent constellation, Orion, are victims of the Earth’s orbit around the Sun. For two months in the Summer (approximately Cinco De Mayo to Independence Day in the U.S.) the constellation is on the opposite side of the Sun from Earth. Astronomers will not be able to see the star at a time that may be crucial to understanding pre-supernova behavior.

Betelgeuse is a variable star that is undergoing a historic expansion, cooling, and dimming (fainting) phase. That process is likely near the end. Next up should be a contraction, warming, and brightening phase. That process will take months…right into Summer. When the curtain drops on Betelgeuse in May, Earth-bound astronomers and astrophysicists will be an audience without a show to watch.

There are multiple possibilities for what might happen. Betelgeuse might increase in brightness over several weeks or months as it has in the past, then resume a normal cycle. It might brighten, but not to the magnitude it has in past cycles. The star might keep brightening to a greater magnitude than it has in the past. Betelgeuse might also brighten suddenly and begin its short-lived supernova phase. No one knows.

What is known is that astronomers will be observing Betelgeuse as long as possible. We will know if something major happens this Summer through other electromagnetic observations and non-Earth bound observation sources, but for amateur astronomers, we will have to wait and not see.

Much Ado About Something

Some astronomers are taking a dim view of the fading light of Betelgeuse. Many are trying to dampen down reports of the star’s demise while not ruling out the possibility. The reality of science is that no one knows what is happening.

What are you doing, Betelgeuse?

A Funny Thing Happened On the Way to a Supernova

Betelgeuse is the hot topic in astronomy because it has been dramatically dimming or ‘fainting’ [SEE Graph 1.0.] In a period of three months, it has dropped from being the eleventh brightest star in the night sky to the twenty-third brightest. This fainting spell is significant because when a star goes supernova it rapidly collapses prior to the event.

Astronomers Edward Guinan, Richard Wasatonic (Villanova University,) and Thomas Calderwood (AAVSO) posted a notice on December 8th of the fainting of Betelgeuse that helped raise awareness of the event. The news media became aware of it and by late December the fainting of Betelgeuse was trending in public speculation of a spectacular doom for Betelgeuse.

A 645-Year-Old Notice

Because of the distance between Earth and Betelgeuse, we wouldn’t know of a supernova event until approximately 645 years after it happens. Our first indication would likely be through a sudden increase in neutrinos. The visual confirmation would occur a few hours later.

If Betelgeuse has gone supernova within the past ≈645 years, then an astronomer could say that Betelgeuse has both gone supernova and has not gone supernova. The delay creates a Schrödinger’s cat scenario. The truth is unknowable.

But astronomers remind us that it may be 100,000 years of more until Betelgeuse makes a stellar spectacle of itself and then abruptly ends its role of marking Orion’s armpit. Their impreciseness of the future of the star is due to a lack of observations of the behavior of progenitor stars (stars that end their life as a supernova) in the years, months, weeks, and days just prior to a supernova.

Betelgeuse is the armpit of Orion

Why Don’t Astronomers Know?

It’s been over 400 years since a star in the Milky Way was observed after it went supernova. That event, like almost every other supernova observation, occurred after the star exploded. Rarely have astronomers been forewarned of an impending explosion and in those cases, the warning has been a matter of hours prior to the event.

To make an accurate prediction of a supernova, we must have data to create a theoretical model of behavior preceding the collapse of the star. The model must be created by using mathematical formulas based on observable data. Without the math, a prediction is just an opinion.

In science, “We don’t know,” is the motivation to discover the truth, even if the truth contradicts the desires and opinions of the majority. At the core of every legitimate scientist is an unwavering desire to offer facts and not mislead others. Astronomers can’t, and shouldn’t, attempt to predict a supernova. “We don’t know,” is the correct answer and the general public has to accept that answer.

Unfortunately, most humans don’t like not knowing. Religions like to give absolute answers to questions even if the answer is unknown or even if it is 100% wrong. A scientist and/or scholar is governed by a higher power of truth. For scientists, not knowing the answer is what makes the process discovery so satisfying. 

The End of the Faint?

In the past week observations of the fainting of Betelgeuse have leveled off. This may indicate that Betelgeuse is about to begin increasing in brightness. It may also indicate the fainting is pausing, or it may indicate that there is no pause and next week astronomers will see a continued drop in brightness. No one knows.

My Answer To the Question

I am not a scholar in the field of astronomy so I can state my opinion about the situation. My opinion is that at some time in the past 645 years, Betelgeuse has gone supernova…and it hasn’t.

You have to love Schrödinger.

During the history of humankind, we have looked up and stared at the center of our galaxy. Most of that time we created stories about it, but now we know some of the facts. If you’re not a space geek, astronomer, or science nut, you may not know what new information has been discovered about the center of the Milky Way. A lot of information has been learned in the course of our lifetime, even if you are only 16 years old.

The Milky Way Galaxy…as it was 26,000 years ago

Dust in the Wind

To see the Milky Way Galaxy requires getting away from bright city lights on a clear night. It looks like a faint cloud running across the sky at an odd angle. What a person sees is light that has traveled from the center of our galaxy for about 26,000 years. Some of those stars are gone, and new stars have formed.

What you may not know is the dim light coming from the central bulge at the center would be brighter than the full Moon if it weren’t for space dust. Near the center of the Milky Way are over ten million stars. If there were no dust we would just see a dazzling glow from the central bulge.

The Story of Black Holes

Our understanding of the Milky Way has coincided with our awareness and understanding of black holes in space. The idea of a black hole was first suggested in a letter by John Michell published in November 1784. The work of Albert Einstein on general relativity led to theoretical work confirming the mathematical possibility of black holes during the first half of the 20th century.

However, the first prospective black hole wasn’t discovered until 1971. At this point, no one suspected that the centers of all galaxies were black holes. It would be 2002 before Max Planck Institute for Extraterrestrial Physics in Germany would produce evidence that a black hole was at the center of the Milky Way Galaxy.

What You Can’t See

The problems with determining a potential black hole are that, 1) as mentioned before, there is too much dust between Earth and the center of the Milky Way galaxy and, 2) a black hole doesn’t emit light. The first problem is solvable by using different wavelengths of radiation other than visible light. Gamma, infrared, and radio waves pass through space dust and allow astronomers to see their source.

The second problem in revealing a black hole is not what they are, but what they do. What black holes do best is produce the pull of gravity. Their gravitational effect is so strong that stars orbit black holes…before they are eaten by it. All astronomers had to do is find an invisible point that stars are orbiting.

Really, Really Fast Stars

It wasn’t as easy as it sounds, but they did it. What is now known as the supermassive black hole called Sagittarius A is at the center of our galaxy. A close group of stars orbit this invisible point at incredible speeds. Astronomers estimate the size of the black hole is big enough to encompass our Sun and extend almost to the orbit of Mercury.

One of the orbiting stars known as S2 comes only as close to Sagittarius A as four times the distance of Neptune is from our Sun. Despite that distance, S2 reaches speeds of 5000 km/s (11 million mph) as it swoops by Sagittarius A and heads back out in a highly elliptical orbit. S2’s orbit takes less than 16 years to make one complete orbit. S2 will make it’s next closest approach in a few months….well, it actually will have happened 26,000 years ago.

NOTE: This article is a secondary article to
Relationships Typing: 3 factors that the affect quality and depth of friendship

As mentioned in the first part of this article, I have defined three factors that seem to determine the quality of my relationships. 1) Trust, 2) Common Interests and/or Experiences, 3) Equality.

By using a 21-point scale to rate each factor in various relationship types we can see how Trust (or the lack of), Common Interests and/or Experiences (or the lack of), and Equality (or the lack of) define the relationship. Below are seven types of benchmark relationships and how they might affect membership retention in a Rotary club.

Too much friendship?

The Star
We all have people who we look up to, but there are just a few people that we put on a pedestal. I see the Star relationship as one where the trust level is relatively high (+7 on a scale of -10 to +10) as well as the common interest level (+8 on a scale of -10 to +10), but we feel inferior (a -9 on a scale of -10 to +10) to this person. In this relationship the depth and quality of the relationship is usually shallow. These people are not close friends, but rather an admired acquaintance. A new member in a Rotary club might see the Club President as the Star.

The Mentor
The Mentor is a different version of the Star. The difference is that we trust the Mentor implicitly (+10) and we have a strong common interest (+9); however, we see ourselves as inferior (-6) to our Mentor. The Mentor has achieved a level of success that we hope reach and our relationship is based on a mutual effort to gain an equal level of success in the future. I think it is a mistake to believe that a Mentor relationship can be imposed. The only successful Mentor relationships I have observed are those that have occurred by a mutual agreement of both parties. In over nine years in Rotary have witnessed few successful Mentor relationships. When it does happen it is a win-win situation for both members, but the Mentor must be highly skilled and/or knowledgeable, a passionate person, and a great trainer. In addition, the ‘trainee’ must recognize the Mentor’s superior knowledge and have a desire to learn from him or her. If not, the relationship will fail.

A Partnership is not necessarily a friendship

The Partner
I see the Partner as a relationship seeking mutual benefit for both people, but without the level of trust of a Mentor relationship. In a Partner relationship the trust is conditional (0, not + or -) and the two people usually see the other as his or her  equal (0) or at least they have something of value that balances the relationship, but the common interest is high (+9). I would consider the Partner relationship to be a symbiotic or co-dependent relationship and while the relationship may seem to be a strong bond, the slightest feeling of inequality or betrayal can end the relationship. In Part I of this series I mentioned that the employer/employee relationship might be a partnership, but I also believe that some marriages can start out, or devolve into Partner type relationships. In a Rotary club a member who has established mostly Partner relationships with other members is likely to have no deep attachment to the club and likely to leave.

The Friend
Of all relationships, I think a Friend is the hardest to achieve. A quality friendship involves a high level of trust (+9) and a significant level of common interests and/or experiences (+6), but also a genuine feeling of equality (0) must exist. The trust and equality factors for a friendship are difficult for most people to offer to another person. It is a special relationship and one to be highly valued, but once achieved it is a strong bond that lasts over time and distance. If every member were to have only one other true ‘Friend’ in his or her club most members would never consider leaving.

The Rival or Competitor
A rival is a relationship, even though we usually don’t think of it as one. It is a relationship based on mistrust (-8) of another person and somewhat ironically, a relationship that includes a high level of common interests (+8). I think that while we may feel we are superior to our rival that the truth is that we are afraid that we are not, thus I give an equality rating of (+3) to a Rival relationship. The Rival relationship is one of the worst possible relationships that could develop in a Rotary club. Sooner or later the club is going to be drawn into the conflict or one or more members will leave because of it. Ironically, it is the high level of common interest that seems to set up the Rival/Competitor situation. Without the envy or jealousy caused by the common interest both people would probably ignore each other.

Common Interest can enhance a relationship, or create conflict

The Subordinate or Submissive
Note that with the Subordinate relationship I am talking about someone who sees another person as their subordinate or submissive. This can be an employer/employee type relationship, but it is any relationship where a person sees him/herself as superior (+10) to another person. The trust level is relatively high (+5) as the person with the bigger ego expects the subordinate to obey their wishes and typically there is somewhat of a common interest (+3), but not necessarily a significant level of commonality. The big problem I have seen with this type of relationship is that the target of this attitude may not feel that they should be the subordinate. In a Rotary club it is surprising easy for a club leader to see other club members as their subordinate. Nothing creates a false sense of power like a title and in a volunteer organization titles are meant to assign responsibility, not authority, but not everyone understands that concept.

The Alien or Blank
It seems somewhat pointless to talk about the lack of a relationship as a type of relationship, but the I find it interesting to understand that some people just don’t show up on our relationship radar even though we may see them on a regular basis. I didn’t fully understand this until I was in Rotary, but after a few years in a club you learn the some people can disappear in plain sight. I feel the lack of a relationship, when there realistically should be is a type of relationship and I refer to it as an Alien or Blank relationship.

The quality of Friendship
I would not argue the point that it takes two to make or break a relationship; however, I would argue that the quality and depth of any relationship is determined largely by our own attitudes, in concert with the way the other person treats us. Understanding the factors that influence a relationship is the first step to making positive changes. In a Rotary club, failing to recognize that not all relationships are constructive can have major consequences on membership retention.

In Part I of this series I talked about a facilitator at a meeting who didn’t want to dilute his ‘friendships’ with people in the Social Media. My response to him is this: friendship is more about what we bring to the table and not the method of connection. The Social Media is not a threat to good friendships, just a different way to engage in them.
