Cosmology and astrophysics address some of the most fundamental and universally fascinating questions in the whole of science: Where did the Universe come from? What is it made of? What will its ultimate fate be? The study of the Universe is inspiring, humbling and in short one of the greatest scientific challenges of humankind.

But by its nature the cosmos is also far removed from our everyday experience. This is part of its mystery and fascination, but it can also become a hurdle when trying to engage the public in a genuine, two-way dialogue. The Hands-On Universe is a public engagement programme to create and deliver innovative methods of connecting the public with our cosmic environment, and with cutting-edge research in astrophysics.

The Hands-on Universe endeavours to reinterpret and understand the big questions in cosmology and astrophysics in terms of our everyday experiences, metaphorically, conceptually, artistically and emotionally. What is the Universe made of? How did it begin? How will it end? What is the nature of reality? How does science work? Award-winning astrophysicist and science communicator Dr Roberto Trotta creates immersive, participative experiences by using do-it-yourself activities, cookery and other fun, unexpected ways of engaging with the great mysteries of the cosmos.

The Hands-on Universe is a programme of outreach and public engagement activities that was sponsored by a Public Engagement Fellowship awarded by STFC (The Science and Technology Facilities Council UK), 2013-2017. The programme was long listed for the National Co-ordinating Centre for Public Engagement Engage Awards 2016.


“We were thrilled to host two g-Astronomy events as part of the Hebridean Dark Skies Festival, marking the project’s debut in Scotland. Roberto is an enthusiastic and engaging host, a delight to work with, and g-Astronomy really captured the imagination of our audiences. Over the course of his weekend at the festival Roberto hosted a cosmic cocktails and canapes evening on Saturday at An Lanntair, and a Sunday evening meal at Uig Sands restaurant on the other side of the island, planning the menus along with the catering teams at both venues and then using the food and drink choices as a launchpad for a fascinating talk about the history of the Universe, spread throughout the evening as our audience enjoyed their food and drink, with lots of food for thought along the way. Both events were sold out and the feedback has all been immensely positive. We look forward to inviting Roberto back to the festival.”
(Andrew Eaton-Lewis, programmer, Hebridean Dark Skies Festival)

“Thank you for your outstanding talk – it was one of the most engaging lectures I’ve seen for this age group and the audience were captivated” (Bhavika Jessani, Outreach Officer, Imperial College London).

“The talk definitely encouraged the girls to want to find out more about the planets and the solar system. They found the talk extremely interesting and it has generated lots of thought provoking questions” (Norland Place School Yr 5 and 6 teacher).

“g-ASTRONOMY is a brilliant idea – what a great way of engaging people in the science of both areas!” (g-ASTRONOMY event attendee).

Multisensory Cosmology

(In collaboration with computer-human interaction expert Prof Marianna Obrist and her team at SCHI Lab at the University of Sussex). For full details, see our paper:

Trotta, R., Hajas, D., Camargo-Molina, J. E., Cobden, R., Maggioni, E. and Obrist, M. (2020). ‘Communicating cosmology with multisensory metaphorical experiences’. JCOM 19 (02), N01.

Much of our scientific knowledge is transmitted via intellectual means, based on abstract concepts and gained through reading and other mostly visual means. This modality of transmission can be hard to engage with on a dialogic basis, as well as on a more emotional level. This is especially true of astrophysics, where we are often dealing with ideas so far removed from the human scale that they are often hard to imagine. Grounding facts and abstract ideas in bodily experience becomes a helpful way of creating meaning and widening participation, especially amongst non-expert and under-served audiences.

We aim to design and deliver two novel multi-sensory immersive experiences, by using insights from research into multi-sensory perception and human-machine interaction in collaboration with Prof Obrist from U of Sussex.

We delivered a first pilot event at the London Science Museum Lates in Oct 2018. The video below gives you a flavour of how the “Dark Matter Multi-Sensory Experience” was received by the public.

Astrophysicist Roberto Trotta joins efforts with molecular gastronomy chef Jozef Youssef and his team at Kitchen Theory to present an interactive culinary experience that translates complex astrophysics into an edible and educational experience for everybody.

Listen to “Out of this world cuisine”: a Physics World podcast by James Dacey covering the g-Astronomy event at Cheltenham Science Festival 2016:

“Astronomy has always captured the public imagination thanks to its stunning images and the sense of wonder it can evoke. But concepts such as dark energy can feel quite abstract and there is a sense that astrophysics research is only done by people with giant brains and access to astronomically expensive equipment. This month’s podcast profiles a new outreach project attempting to make cosmology more palatable – literally – by serving space-inspired canapés accompanied by a cosmology lecture.”

g-ASTRONOMY @ Cheltenham 2016

Supported by the Institute of Physics, and the Royal Astronomical Societyg-Astronomy is a groundbreaking outreach project that creates a immersive, multi-sensorial gastronomical experience to engage the public with some of the most fascinating questions of modern astrophysics and cosmology: the nature of dark matter; the properties of black holes; the origin of the Universe.

Artists David Cheeseman and Ole Hagen collaborate with astrophysicist Roberto Trotta for week 20 at fig-2. Their exhibition entitled ‘All There Was’ predicates a post-Newtonian orrery, concentrating on the depiction of the All-There-Is and its modelling. The exhibition builds its premises by looking into how we explore the cosmos – observationally and intellectually – and reflects on our understanding of it within the given parameters known to us. Basing its subject-matter on the dichotomy of presentation and the real, ‘All There Was’ is an aesthetic and intellectual speculation of post-Euclidean Geometry basing its forms on a reinterpretation of abstract concepts such as dark matter, dark energy. Cheeseman, Hagen and Trotta will highlight the transformation of fig-2 premises into a temporary laboratory of ideas, through their performative conversation on Monday evening that will speculate about the ‘Big Picture’, the grand scheme of the reality we reside in.
