Talk To A Scientist

You have a question about the foundations of physics but don't know where to even start? Now you can talk to me or someone from my team of consultants on skype at US$ 50 for 20 minutes.

Besides physics, we now also offer philosophy, geophysics, biology, volcanology, and neuroscience!

To set up an appointment, please send an email to hossi at

Terms and conditions:

The payment is to be made by PayPal. Half of the fee is due at least 24 hours before the scheduled call, the other half after completion. If the conversation does not take place due to fault on our side, you get a full refund. If you feel that we have not delivered the service we offer, you do not have to pay the 2nd half of the fee. In this case however we require a written explanation of our shortcoming.

During our conversation, you can ask us anything you want to know about physics!

My own expertise is in: cosmology, quantum mechanics, general and special relativity, quantum gravity, unification and the theory of everything, particle physics, and general questions about academia. On my team are also experts on: quantum foundations, astrophysics, and string theory. I am sure we have you covered. All of us have a PhD in physics and many years of research experience.

We do not counsel students for homework assignments and do not review written material.

Thanks for doing this -- it's a great idea!

Eric Stroud said...

Can we request a specialist in a particular subject if we believe that we have a good grasp of fundamental physics? For example, the Black Hole information paradox.

Sabine Hossenfelder said...

Yes, I try to address special requests to the extent possible.

Juan Pablo Carbajal said...

Are you looking to extend your team anytime soon? (with other fields of physics)

Sabine Hossenfelder said...


Maybe. Please send an email to the address mentioned above.

Rosemary Ainslie said...

I keep replying here and see nothing forwarded. Again. I would like to have your email address in order to consult with you.

Sabine Hossenfelder said...


I don't know what you mean. The comment above is the only one from you that was submitted. My email address is in the above post.

Rosemary Ainslie said...

Sabine - thanks for this. I actually have sent an email. Hopefully you'll engage on the subject.

This is an awesome idea. I'm a layman in this, but I still have a couple of "thoughts" that I've never seen in the literature (well, actually, I found one with similar thinking as I on some very ugly looking website, and he had all the math, which I don't, but nobody had given a crap about this guys website).

Either these "ideas" are so blatantly obvious that nobody even mentions them, have been discounted so many decades ago that nobody even mentions them, or are so obviously wrong that nobody mentions them, but... nobody mentions them. :D


R. R. Edwards said...

Is the email address still working?

Sabine Hossenfelder said...

Yes, still the same email address.

Edwin said...


Can I, instead of talking to physicists, request a written review on a physics thought experiment (about 2 pages), on its logic, relevance, understanding of physics, the thought experiment goal and validity of its claim.

I am not a student. I am an engineer nearing retirement.


Sabine Hossenfelder said...

Hi Edwin,

No, we don't review papers or proposals. We answer questions.

Phillip Helbig said...

The best way to get an article reviewed is to submit it to a journal.

Sehr geehrte Frau Sabine Hossenfelder,
Is it possible to subscribe to a newsletter of your blog?
Vielen Dank

Sabine Hossenfelder said...

Hallo Herr Boch,

In the side bar below the visitor could you can subscribe to this blog's posts. Or so I believe. I've never tried if it works. If it doesn't work, please let me know!

Regarding the stagnation of physics, could a symptom of this be related to the fact our government is stamping everything do not release for "Reasons of National Security" currently there are thousands of patents (ideas) being hidden from the public, everything from Anti-gravity technology to anti-aging drugs. I believe by hiding the latest breakthroughs not only causes stagnation in science it also causes stagnation of our society.
