Of every unanswered question in your field, what do you think is the least likely to be answered in the next 10 years and why?

Ed Copeland is a brilliant contributor! How long does the nuclear ignition stage take when a star forms? Milliseconds? Mintues? 1000s of years? Is it like switching on a light or getting a bbq up to heat?

Maybe it’s a bit too bold too ask, but do they agree with Sabine Hossenfelder’s claim? Are we really just building larger and larger hadron colliders, hoping to find particles that we have no reason to believe they’re there, except for the mathematical beauty?

Unrelated, but I’d love a sort of debrief interview with Prof. Merrifield. Over the next couple months he’ll be thinking about his life and his work in a different way, it would be interesting to hear about it.

How do theoretical physicists come up with mathematical models to describe what's happening? I mean their reasoning behind it and what mathematics (and why) they choose. What's the process of developing a new theory and so on!!!

If you get to Padilla, if he had an opportunity to develop and prove a theory that unified the fundamental forces (through string theory or other means), but it meant that Liverpool would never win the premier league again, would he do it? Also I love his book. Same for Copeland if he has a team.

Concept of absolute values. Especially something like the lowest speed possible. We can agree that the fastest speed is the speed of light - but how would we tell the slowest moving object in the universe? Is there inverse time dilation once you stop moving in the "absolute" reference frame. You can tell how fast your reference frame is moving by observing the speed of light right? Another question I always have is how does destructive interference really work? Like you can't destroy energy - it has to go somewhere. With something like noise cancellation for audio - you essentially warm up the air. But light can be interfered with in a vacuum - and you can do like crossed lasers where there is a static region of no light (see recent short by Huygens Optics)

I’d like to know what Dr. Copeland is working on, and if you could draw it out as long as possible that’d be great

I have a hypothetical! Some time back I had a sudden realization that "time" is not real but that it is an emergent property of force, be it any force because the only reason we can say that one moment in time is different from the next moment in time is because things move and that happens because of the forces acting upon them. That made me conclude that if there were a universe where "forces" didn't exist, then the concept of time would be irrelevant. This is something that I had heard about but never really understood what physicists meant when they spoke about time. I'm sure my way of thinking has flaws and/or is very immature about how a physicist would think about time and I would love to understand it better. I would love to hear Prof. Ed Copeland share his views about it.

Any thoughts on Penrose's idea of Conformal Cyclic Cosmology - listening to him talk about it is very interesting! :)

Can you explain what a photon is at several levels of difficulty? (I.e., to a child, teenager, grad student)

Im choosing a Ph.D program right now... i was just curious what made the professors choose the programs they did? Was it a particular professor or just based on gut or general program appeal?

Have they ever had any numberphile/sixty symbols fans approach them before? If so, did they mind?

Does loop quantum gravity offer a better explanation for black holes than general relativity? Which model do you prefer?

I love the extended Copeland interviews, I regularly fall asleep to them. Hence my question: any news on cosmic strings?

Let's say thereotically we can travel without the limitations of the speed of light (just pop up anywhere like), do you think the universe is infinite or finite in this scenario? If it's finite, what shapes could it be, and do you have a favorite shape you'd want the universe to be?

Which type of project post grad students do in these types of advanced topic.

Sixty Symbols
I have some free time tomorrow with Ed Copeland (and maybe Tony Padilla)...I was going to fire some questions at them from the viewers (that's you) - what would you like to ask them?
Cosmology? Particles? Big Bang? Black Holes? Serious? Funny? Personal? Hypothetical?
