Una densidad de energia infinita a tiempo finito no es física. En ese punto tenemos una singularidad. Quiere decir que perdemos predictibilidad en la teoría, es decir, que nuestra teoría allí no es válida y no sabemos decir que es lo que pasa.

Al comprimir la materia se alcanzaría una densidad infinita del universo, lo que daría lugar a una singularidad espacio-temporal.

La teoría del big crunch propone un universo cerrado. Según esta teoría, si el universo tiene una densidad crítica, la expansión del universo, producida por el Big Bang, irá frenándose hasta que finalmente comiencen nuevamente a acercarse todos los elementos del universo.

Hace días una persona random me escribió para preguntarme sobre si tiene sentido físico la predicción de la teoría del #BigCrunch la cual dice que el universo podría colapsar y alcanzar una densidad infinita. Pedí ayuda a un par de amigas cosmólogas y como la respuesta conjunta quedó bonita la dejo por aquí:

All of us. From all parts of society. #Science community included.

All of us should support the right to decide, the right to have free and desired maternities and be against giving birth forcefully.

My job lately has been about making my derivations as short and simple as possible. I just summarized a two pages derivation in half a column.

Day 2!
Extreme computing stuff

A very interesting thought at the end of the talk is how usualy it is easier for us to adquire new IT material instead of investing in IT staff or mantainnance. Thoughts about why?

Now we have IT news about #IPARCOS collaboration introduced with this very cute slide 💜

Finally, #JENAA aim is to join different collaborations within high energy physics. It joins all the activities done at ECFA NuPECC-APPEC groups 💪

The #LHCEW working group at cern aims to analyze precisely the Z boson spectrum in transverse momentum because this allows to extract the W mass with a very high precision.

The EIC Yellow report can be found in arxiv. It explains how EIC will be used for hadron tomography, jet physics, Beyond the Standard Model physics and also social applications.

Now I. Scimemi is presenting the #IPARCOS participation at #EIC #CERN and #JENAS

Amazing how #deeplearning and #GPU based methods can be also applied to medical physics and radiation therapy. For instance, to compute the dose needed in the treatment.

Now I'm listening to a gamma ray talk and how to use machine learning on their imaging process

This talk starts talking about the scientific method and how artificial intelligence has some differences 🤔

After a session of instrumental development the talks about extreme computing begin!
