Small effort, big gains
Clearly, a lot of progress has been made toward making the space lab more analogous to the Earth lab in the past few years, and NanoRacks has played no small part in those improvements. Despite the challenges that still remain for microgravity research, some truly significant work has been accomplished. With just a little more investment, Carruthers believes, much larger gains can be made.
CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?
CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.
Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”
“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”
There have been broad discussions about whether high energy nuclear experiments could pose an existential risk sooner or later, for example by producing micro black holes (mBH) or strange matter (strangelets) that could convert ordinary matter into strange matter and that eventually could start an infinite chain reaction from the moment it was stable – theoretically at a mass of around 1000 protons.
CERN has argued that micro black holes eventually could be produced, but they would not be stable and evaporate immediately due to „Hawking radiation“, a theoretical process that has never been observed.
Furthermore, CERN argues that similar high energy particle collisions occur naturally in the universe and in the Earth’s atmosphere, so they could not be dangerous. However, such natural high energy collisions are seldom and they have only been measured rather indirectly. Basically, nature does not set up LHC experiments: For example, the density of such artificial particle collisions never occurs in Earth’s atmosphere. Even if the cosmic ray argument was legitimate: CERN produces as many high energy collisions in an artificial narrow space as occur naturally in more than hundred thousand years in the atmosphere. Physicists look quite puzzled when they recalculate it.
Others argue that a particle collider ring would have to be bigger than the Earth to be dangerous.
Since these discussions can become very sophisticated, there is also a more general approach (see video): According to present research, there are around 10 billion Earth-like planets alone in our galaxy, the Milky Way. Intelligent life might send radio waves, because they are extremely long lasting, though we have not received any (“Fermi paradox”). Theory postulates that there could be a ”great filter“, something that wipes out intelligent civilizations at a rather early state of their technical development. Let that sink in.
All technical civilizations would start to build particle smashers to find out how the universe works, to get as close as possible to the big bang and to hunt for the smallest particle at bigger and bigger machines. But maybe there is a very unexpected effect lurking at a certain threshold that nobody would ever think of and that theory does not provide. Indeed, this could be a logical candidate for the “great filter”, an explanation for the Fermi paradox. If it was, a disastrous big bang machine eventually is not that big at all. Because if civilizations were to construct a collider of epic dimensions, a lack of resources would have stopped them in most cases.
Finally, the CERN member states will have to decide on the budget and the future course.
The political question behind is: How far are the ordinary citizens paying for that willing to go?

Network to discuss the risks at experimental subnuclear particle accelerators
I’m excited to share my new article from Quartz on how science will make it safer and easier for a 50-year-old woman to have a child in 2028 than a 25-year-old woman today. #IVG and #DelayedFertilityAdvantage are game changers.
Women’s biological clocks drive human conception—and, in turn, human history.
Biology’s inflexible window of female fertility is generally agreed to be between the ages 18 and 35. Any older, and the risk of miscarrying, not getting pregnant at all, or bearing unhealthy children skyrockets. When the average lifespan for a woman in the Western world now hovers at around 80 years old, this means that less than 25% of her life can be spent easily (and safely) procreating.
Men have the luxury of being able sow their seed for most of their lives with few health ramifications (which is why someone like 72-year-old US president Donald Trump has a 12-year-old child). By comparison, the average woman will only ovulate 300 to 400 eggs in her lifetime, which means she only has the same amount of menstrual cycles to ever pursue procreation.
This seemingly unfair accident of human biology is all about to change, thanks to transhumanist science. Genetic editing combined with stem-cell technology will likely make it safer for a 50-year-old woman to have a baby in 2028 than for a 25-year-old woman in 2018. In two decades’ time, healthy 75-year-old women could be starting new families once more.

Data Science Salon Austin, Feb 21–22 — Register Now
With support from the National Network of Libraries of Medicine, the School for the Future of Innovation in Society at Arizona State University and SciStarter invite libraries to be part of Citizen Science Day on April 13. Now in its third year, Citizen Science Day is expanding to include meetups and events with a special focus on supporting libraries to involve their communities in authentic science projects in need of their help. The signature event this year will be the “Stall Catchers Megathon” by the Human Computation Institute. Complete the registration form to sign up.
Scientists in Europe and the United States face an uncertain political landscape in the new year, which could affect funding and collaborations. The threat is most acute in the United Kingdom, which plans to exit the European Union in March but has not settled on the terms of its departure. Some big research findings could share the headlines, however, including the first clear images of the supermassive black hole at the heart of our galaxy, from astronomers in an international collaboration called the Event Horizon Telescope. Science’s news staff forecasts other areas of research and policy likely to make news this year.
Science’s news editors and writers predict this year’s biggest developments.
China could emerge as the world’s biggest spender on research and development, after adjusting for the purchasing power of its currency, once countries publish their 2018 spending data in late 2019. Outlays on science in China have accelerated since 2003, although the country still trails behind the United States on measures of research quality. Over in Europe, officials will try to agree on how to disburse a proposed €100 billion (US$110 billion) through the European Union’s next research-funding programme, Horizon Europe, which begins in 2021. It’s unclear how fully UK researchers will be able to participate, as uncertainty over Brexit continues to plague the country.
Gene-editing, open access and a biosafety rethink are set to shape research.
