0:00.0	When Galileo invented the telescope, people didn't want to look through it.
0:04.0	And that also makes me think about a lot of the stuff happening in science
0:08.0	where people refuse to look at certain theories.
0:13.0	For decades, reconciling quantum theory with gravity
0:18.0	has been the holy grail of theoretical physics.
0:21.6	But what if the path forward isn't through ever more convoluted mathematics,
0:26.4	but rather through ingenious experiments we could perform right now?
0:32.3	Professor Yvette Fuentes, the close collaborator of Roger Penrose, is proposing just that.
0:39.1	Groundbreaking tests using ultra-cold atoms and quantum technologies that could probe the ostensibly quantum nature of spacetime.
0:48.4	Yet, despite its potential, many researchers in the field are hesitant to pursue these ideas. Is it the allure of
0:56.3	purely theoretical work, the inertia of established research programs, or simply the challenge
1:02.6	of breaking away from fashionable thinking? In this episode, we'll explore Professor Fuentes'
1:08.2	inventive approaches to testing quantum gravity and why they're
1:12.6	being overlooked by much of the physics community.
1:20.5	Professor Yvette Fuentes, it's a long time coming. I'm super excited to have you on here.
1:26.5	The audience, it's going to be a treat for them.
1:28.5	They don't realize it right now, maybe, but the audience is in for a great treat. So, thank you,
1:34.0	and the floor is yours. Thank you very much. I was just telling you just now that I love your
1:41.1	podcast and I listen to it, see it very often, let's say.
1:46.5	So it was very nice meeting you just now because I felt that I've met you forever.
1:52.3	So this is a feeling after seeing you often in the evenings and then it's like, oh, wow, that's you there.
1:59.5	So that was really very nice.
