Social media environments have enjoyed massive growth recently and, with this, absurd theories are being accepted as science and factual truth while spreading considerably in society. There seems to be no consensus regarding controversial topics such as creationism or global warming and even regarding the shape of the Earth. In Brazil, although the “Big Bang Theory” series was shown for general audiences on TV, the scientific dissemination is mostly limited to children while paying no attention to the adult audience. Academia sometimes engages in some actions, but without a wide reach and with low popularity. The search for a connection between science and art is certainly complicated, due to the exhaustive scientific activity of researchers, who are not able to present themselves as artists or art-related most of the time. One of the best options to bridge this gap is to invite educational artists and more colleagues in the sciences to work together. To this end, the theatrical play “The earth is flat! And, now what?” (in Portuguese: A terra é plana! E agora?) was created and first shown at the General Assembly during the European Geoscience Union (EGU) 2019 (França et al., 2019a), followed by five performances in theaters. This play won the DF 2019 Theater Award Category: Local Circulation Show. The play uses a clown to explain the whole process of creation, connecting science and art while applying our research to improve the understanding of the audience of the topic at hand. Suspendisse a elit ut leo pharetra cursus sed quis diam. Nullam dapibus, ante vitae congue egestas, sem ex semper orci, vel sodales sapien nibh sed lectus. Etiam vehicula lectus quis orci ultricies dapibus. In sit amet lorem egestas, pretium sem sed, tempus lorem.

Palma (2006), in his experience with the art and science project on stage, reports that, although theater is a powerful tool for disseminating scientific principles, implementing this integration is permeated with difficulties. This project won several awards and had great repercussions in the community. The dialog between science and theater is old; however, it is still a localized movement with little material available, especially in Brazil. Among the experiences in Brazil, Almeida et al. (2018) presented their successful and continued project for integrating science and theater at the Museu Ciência e Vida (Museum of Science and Life) in Duque de Caxias-RJ. On the other hand, our work focuses on the Earth sciences field and art, which are still very little explored. Firstly, several pieces of information on the flat Earth subject were collected from the groups found in the social networks defending this point of view and news refuting this theory; after that, the scenes were created. In the show, the introduction scenes are based on Mamulengo, which is the Portuguese name given to the puppetry theater, also known as marionettes and/or puppets. Culturally, it is one of the richest popular spectacles of northeastern Brazil, in which a dramatic representation using puppets is played on a small elevated stage covered by a curtain to hide the people/actors giving life and lending their voices to the characters. Depending on the play's nature, the puppets are handled by hand, stick, metal stick, or string (Gaspar, 2021). This first scene introduces Dr. Terremoto (Dr. Earthquake), the show's protagonist, which is followed by a short lecture showing at least three slides. In the next scene, a text about the big bang theory was adapted from Oliveira (2019), recorded, and presented as a choreography. After that, Dr. Terremoto sings a song written by Thomazoni (2013), which was inspired by the opening of the “Big Bang Theory” series. Also, scenes from França et al. (2019a) (Fig. 1) featuring Newton and gravity based on the fall of the apple myth presented in the EGU session are shown. This scene is followed by the story of the planets, which are represented with balloons and a Pilates ball, based on the film “The Great Dictator” by Charlie Chaplin and, finally, the “Earth is Flat” speech.

The scenes' creative process lasted about 6 months while being evaluated weekly during the rehearsals. The costume worn by the storyteller actor consisted, initially, of a black suit with red details and checkered pants, which were later replaced by brown shorts and coupled with wine-colored socks, a white shirt, and suspenders to complete the costume. The idea behind the storyteller costume was to pepper it with some clown props. The dramaturgy was a compilation of the scenes described above and was then improved and adapted during rehearsals. After that, we held an open rehearsal, in which local artists and scientists were invited to talk and discuss the show before its premiere. After the play itself was ready, we had to plan for a practical scenario that was easy to move around, so we chose a folding screen, a pulpit, a ball, and a transport crate.

Overall, the play was shown two times at different times of the day during international conferences (França et al., 2019a, b) and seven times in theaters to an audience of 316 people considering only the seven theater performances. The presentations took place at the following venues: the FAP-DF on 12 October; Casa dos Quatro from 15 to 17 November; Oficina Perdiz from 21 to 22 December; and participation at the FICA festival of Casa da Ribeira in the city of Natal-RN on 29 December. The presentation posters and photos are shown in Fig. 2.

The audience was invited to evaluate the performances by filling out a previously handed Google form consisting of nine questions and an optional comment that was available to every audience member. Of the 316 people who watched the show, only 11 % answered the questionnaire. This low number of respondents is probably because, in Natal, where we had the largest audience, the questionnaire was available only after the last performance, whose audience consisted of several known people and friends. Nevertheless, the questionnaire answers steered us toward several reflections on both the artistic point of view and scientific dissemination.

Figure 3 shows the histogram of the responses and the audience. The questionnaire responses were given by audience members who watched the shows as follows: about 40 % at Casa Ribeira in Natal-RN, followed by 37.1 % (three shows) and 25.7 % (two shows) at Casa dos Quatro and Teatro Oficina Perdiz, respectively, in Brasília. Therefore, the responses were well distributed among the show audiences, which also included professionals from academia during the presentation held in Natal-RN. The more diverse audience in Natal was because the play was presented during a theater festival, FICA, which presented the first review of the play by the collective Farofa critics. This review is available only in Portuguese on the Farofa Critica website (Costa, 2021).

The majority of the public, 82.8 %, had a high degree of understanding of the Earth's shape, and, certainly, the title makes the public more aware of the subject (Fig. 3a). The number drops when the question is a little more specific; however, it is well discussed in high school. Furthermore, 69.6 % of the public knew about the law of universal gravitation (Fig. 3b). In the last question on heliocentrism, 20 % of the respondents did not know what it was (Fig. 3c). The results directed us to believe that the audience had excellent knowledge of the subject, whose understanding was apparent given the audience's laughter during the play.

The second part of the questionnaire concerned scientific dissemination and had, among the questions, one that asked the respondents to associate one word with the play they just watched. Figure 4 shows a word cloud highlighting the answers of the audience describing the show as didactic, interesting, fun, playful, and genial, thus showing the play's general acceptance by the public. The next question asked the audience to score the play between 1 and 5 (low to high dissemination) regarding science dissemination; 83 % gave scores of 4 % and 5 %, and 17 % gave a score of 3, showing again the importance of this play used at least in the Federal Capital of Brazil (Fig. 5).

Furthermore, only 40 % became even more curious regarding the Earth's shape: this is because the vast majority of the audience were aware of the Earth's shape and certainly did not believe that a flat Earth surface is feasible (Fig. 6).

The overall score results indicate that 80 % of the audience assigned scores 4 and 5, thus recommending the play to other viewers, similarly to the scores assigned to scientific dissemination. Therefore, it can be concluded that the play was well received by the public (Fig. 7).

The general comments about the play highlight that the show is not completely ready yet, especially the end of the play; questions the reason for using “mamulengos”; and the issue of the flat Earth and the physics speech. Another comment about the play regarded the actors' training and qualification in the field of sciences. Finally, all comments are going to be used for updating the play and trying to present the best show.

Creating a play is a long and arduous process, but when it was finally presented we realized it is an excellent way of informing and publicizing the subject at hand. The public who, for the most part, had prior knowledge of the subject took into account the scientific dissemination nature of the play and considered it an excellent show. The show had a good reception in the local community, winning the DF 2019 Theater Award Category: Local Circulation Show.

The importance of disseminating sciences using art as a tool opens a popular space for science while also presenting shows to a new kind of audience that is not frequent in this space. The possibilities for exploring this path are endless, but still, few come to fruition. We need to connect art and science, aiming to strengthen both education and art, which together should further guarantee the quality of scientific dissemination. In addition, researchers should embrace scientific dissemination as an important role played by scientists and participate as collaborators in most dissemination activities. By participating in these activities, explaining well their role in society while establishing the connection between science and art can make science and knowledge more popular, stimulating and boosting science in all areas.

The next steps are to present the play in public and private schools, to tour Brazil, and to invite more undergraduate students to participate in this project.
