Hi everyone -- Marcus's son here. Thank you all for the love and warmth here in this thread.

To answer the question about "what happened", it was esophagus cancer -- we found out about it in September, but by that point it was advanced to a level where not much could be done. We tried anyway -- chemo, radiation, etc. But, well...

I know he cared a whole lot about all of you guys. When I would see him or talk to him on the phone, he would often update me on what was going on here on PF, and how he was starting a poll or posting a summary of various papers or whatever else he would do on a regular basis. I empathized with how he felt about PF, since my generation grew up with the internet and I thought it was wonderful to see him bonding as deeply with you guys as I've bonded with the online communities I'm part of.

You guys rock. Hugs to you all.
@tamwuff Our PF loss here is certainly not as profound as the loss that you and your family feel. So please accept my condolences.

Marcus certainly was the one who single-handedly ran the BTSM forum for as long as I can remember. There was no doubt that it was his baby.

Zz.

I'm very sorry to hear this. Marcus has been a constant presence here, as far back as I can remember. Of course, it has been a longer presence for his family, who have the greater loss. My condolences to them.

My condolences to you, tamwuff, and to the all of marcus' family. Marcus and I never met in person, but I certainly consider Marcus to be a friend. Marcus and I had many, many interesting discussions about cosmology that were very enlightening for me. He has an enduring invaluable legacy here at Physics Forums; I am sure that years from now, I will search Physics Forums for some particular topic in cosmology, and I will find the information that I seek in posts by marcus.

My condolences to you and your family, @tamwuff, I'm so sorry to hear this. Marcus had an enormous presence here at PF, and taught me a lot about cosmology when I was much younger and just starting out in my career. He had a vast knowledge of many different areas, and his keen interest in following the quantum gravity literature -- and understanding it -- was inspiring. Marcus will be sorely missed, and leaves a legacy here at PF.

Hi everyone -- Marcus's son here. Thank you all for the love and warmth here in this thread.
tamwuff, thank you for the notification. We are greatly saddened by the passing of marcus. It is hard to comprehend at the moment. I had a number of pleasant exchanges with marcus, mostly on ancient history and culture, as well as a few on astrophysics and cosmology.

marcus certainly established a high standard at PF. Now he is among the stars with other giants of PF, selfAdjoint, whom he mentioned in the thread cited by Greg B, and arildno, with whom he shared an interest in old literature and history. Peace upon him and your family and friends whom have lost such a wonderful person. He is forever in our hearts and minds.

Another thread started by marcus with contributions by selfAdjoint.

I'm very saddened by this news. marcus was one of a kind. He was a great educator with a brilliant writing style and immense knowledge, he explained complex ideas with a lot of patience, and he never made anyone feel bad for taking time to understand what's being said.

My sincere condolences.

I am very saddened by this loss. I can't imagine how the family must feel. My feelings regarding the loss of this exceptional man are probably less than 1% of what the family has to go through, and I am already devastated.

I am very glad that marcus found in this forum a safe haven. A place to discuss his interests with peers. We will surely miss him a lot.

I just wish he could have read all these messages before he passed away. I hope he knew how loved he was.
 
I'm sorry to hear this. I don't go much into the more academic forums anymore but I've seen enough of his posts to know that he was one of the best that PF has to offer, and that's saying something.

I never had the chance to interact with @marcus since I have no background of many of his areas of expertise. But seeing his profile, content and feelings of members in this thread, I can see he had a vast scientific knowledge:bow:. He was surely one of the best science advisors here on PF! I now wish I had a little knowledge of any of those topics and I could interact with him. It would have been a great experience! My condolences to his family! Rest in peace marcus!

Hi everyone -- Marcus's son here. Thank you all for the love and warmth here in this thread.
My condolences. I interacted with him a couple of times. He was a frequent poster in the Cosmology and Beyond the Standard Model forum, and he was always friendly and very interested in many things. I am sad by the news :frown:.

I have since long known that if I decided to cling actively on a forum like PF comprising people of all ages, on a certain day I will get notified about the resignation of a certain member. Just, I never have thought that this time's notification of leave, that came less than two years since I joined in PF, is about an unwakeable rest.
For a theory that bears the potential of revolutionizing physics, Marcus's retirement is a big loss.
Deep condolences for the deceased's family and relatives.

Hi everyone -- Marcus's son here.
Condolences to you and family.
We know that he will be severely missed your family, but also on this and quite a few other science forums.
Without your dad's inspiration and support, the community-development of the LightCone cosmological calculator would probably not have happened.
