Prof. Jeffrey S. Hangst is a founder of the ATHENA antihydrogen collaboration and was the Physics Coordinator of the experiment that produced the first cold antihydrogen atoms at the CERN Antiproton Decelerator in 2002. He is founder and spokesperson of the ALPHA collaboration at CERN, which demonstrated trapping of antihydrogen atoms in 2010, and the first laser spectroscopy of antihydrogen in 2016. Jeffrey is a graduate of MIT (SB, SM) and of the University of Chicago (PhD). In Chicago, he worked at Fermilab and at Argonne National Lab. He moved to Aarhus University in Denmark in 1993 and has been there since. He received the European Physical Society’s 1996 accelerator award for a young scientist for his work on laser cooling of stored ion beams in the ASTRID storage ring in Aarhus. He holds numerous prestigious awards and is a member of the Royal Danish Academy of Sciences and Letters. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

Where is the anti-matter? I saw you giving this lecture again in Danish (my respect!) a few days ago. Although it does not solve the question of the imbalance between the matter and antimatter, the mentioning of negative solutions of Dirac made me wonder if the antimatter universe went down the negative time line from the big bang. That is to say, an inequally opposite antimatter universe restoring some of the necessary symmetries of the standard model.

When we expect spectroscopy of antihydrogen molecule? at 1000K one expects equilibrium between 1 antimolecule and 50 antiatoms (per cm^3)

To obtain financial freedom, one must either be a business owner, an investor or both, generating passive income, particularly on a weekly and monthly basis. That's the key to living a financially stable life. This trick has never failed. I pray that anyone who reads this will be successful in life and put this basis to work and practice. Jessica Darrell have been a great manager, mentor and guide. Her support and advice has helped shaped my crypto trading career.

I get a lot of recommendations for Jessica Darrell from friends. Her strategy must be good for people to testify a lot about her.

Whole life is a joke in every sense, the investment side of a whole life policy gives the poor return and stabilized the rich

How does this whole crypto thing works I'm interested in it and willing and ready to invest heavily but I need an assistant to properly guide me through on how to make a good startup and be successful in it without making mistakes
