Hi Everyone,

What are the best universities in Europe/America with PhD programs for Gravity/Quantum Gravity and Cosmology? I know mainly I should look at researchers/professors papers and start from there, but what are in your opinion the best centers/universities where these topics are currently being researched?

Should I take a String-theory course since many of the researchers I see, especially in America, appear to be in that field as well?

Hi Everyone,

I'm actually finishing my master's exams in Theoretical Physics and need to ask for a thesis. My coursework is heavily related to gravitation, cosmology, and astroparticles, and I'd like to start working on a thesis related to gravity, which might bring in some of my interests in quantum information/QM.

During the courses I've been fascinated mainly by GR and ultimately by the results we're able to obtain merging it with QFT (QFT on Curved spaces) and quantum information - eg. Hawking radiation, Reheating and Pre-heating in cosmology, Naked singularity/Censorship conjecture.

My objective is to obtain a PhD somewhere between Europe and America afterwards, and I'm struggling to decide good topics that might be suitable for a future PhD and yet interesting to me - I've heard gravitation is generally less "researched" and therefore more PhD are being offered to astroparticle students.

I'm here asking for some suggestions on interesting/hot topics related to arguments like the following, in order to make a decision regarding my future:

- Time Emergence/Entropic gravity - is it something being researched?

- Quantum information applied to BH

- Holographic principle

- ER=EPR

- Wormhole - I know it's something purely mathematical, yet does anything new come up regarding it?

Do you know other arguments related to gravity being researched at the moment? (eg. MOND?, f(R) gravity?)

[The list is not extensive - it's just a list of keywords of things I find fascinating and might be similar to things I don't know atm].

EDIT: I understand these are important/hard questions - I don't want to address all of 'em nor solve 'em (cause I wouldn't be able to mainly), but I'd like to touch some of these problems while researching/calculating for my thesis.

Thanks everybody for the answers/suggestions!

**Note:** Any suggestion on PhD seeking in this field is appreciated as well!

Hi!

I'm a University student and recently came to know my university has a little rocketry team which is seeking new applicants in order to participate to few competitions and learn together.

I'm a theoretical physics student, therefore my support in something that's not mainly computational/physical is more than useless under the constructional/testing perspective, but I do enjoy the challenge and would love to take part in the project under certain departments (I've been proposed dynamics/CFD simulation, material study for the rocket model or similar trajectory study) and despite being interested since I was little in the cosmo and astrophysical subjects (my thesis is going to be on cosmological correlators and CMB fluctuations), I've never dug into rocketry/propulsion and therefore I'm feeling a little lost.

Can anyone give me some advice regarding useful textbooks/PDF/resources to understand part of these concepts, or some general introductions to the subject (eg. I'd like to have a little historical and "phenomenological" culture regarding rocketry/rockets types/milestones reached by human, and not just being able to manipulate the various propulsion equations without having a glance of the different types of engines/materials/rockets existing.

Right now I'm starting to read the "Handbook of model rocketry" manual, but it appears to be quite old and wanted to know if there's something more recent and what's your opinion on it.
