Thanks for the correction, it is an honor for me to be alive in this time!

Here it is, the first real immage of a Black Hole in the center of the galaxy M87.

"On April 10th 2019, the Event Horizon Telescope (EHT) Collaboration will present its first results in multiple simultaneous press conferences around the world, and many satellite events organized by its stakeholder and affiliated institutions. Press conferences will be held simultaneously in Brussels (in English), Lyngby (in Danish), Santiago (in Spanish), Shanghai (in Mandarin), Tokyo (in Japanese), Taipei (in Mandarin), and Washington D.C. (in English), starting at 13:00 Universal Time [...] Major press conferences will be streamed live online via the following channels: Brussels: European Comission Youtube Channel Tokyo: National Astronomical Observatory of Japan channels on Youtube and Niconico Washngton: National Science Foundation Live Stream " Simulations and expected results can be found here : https://eventhorizontelescope.org/simulations-gallery More informations : https://eventhorizontelescope.org/science What do you think/expect, are you excited ? I surely am!

Thanks, i will give a look !

This question would need a whole book to be answered. In short: there are many types of brain injuries associated to memory problems such as : stroke,brain turmors, head trauma,cerebrovascular disorders, cerebral infections and others. Also a lot of others patologies such as Alzheimer disease or dementia ( just to name two of many ) can cause memory loss. In order to have strong memory problems, usually, there are three main areas that mainly needs to be damaged ( note that the type of damage and the area where it happens can determine many different deficit) : 1. Mid-Dorsal Nucleus of the Thalamus 2. Mamillary bodies 3. Hippocampus All of the above are neuropsychological diseases caused by brain injuries that do not occur normally. Memory loss can occur also with age ( the age at which they occur mostly depends on the individual lifestyle), and its usually caused by the deterioration of neural synapsis in the brain. Note that recent studies show that intellectual activities, physical activities and general learning can drastically reduce normal memory loss.

Hello, i am a student of Neuroscience at University. I love neuroscience and science in general, in particular Physics: i love to question the base of reality and it's mechanism. This passion made me explore Physics by reading famous books of great scientist and communicators like Neil DeGrasse Tyson, Lawrence Krauss, Brian Green, Stephen Hawking etc. But now, i realised I would like to learn things more deeply, expecially the match behind it, unfortunately it is impossible for me to start a new University degree in Physics, i would do that ( if i had another life to live )but my career in neuroscience would be impacted. Is it possible to learn Physics and Theoretical Physics alone, self learning it ? No matter if this will take 5-10-20 years. How do i start ? What do i do ? I would love to hear some advice. Greetings, Massimo. P.S. My knowledge of Mathematics and Classical Physics is basically 0, i know statistic quite a bit and it's application in brain research.

Yes i do.

Thanks for your answer, i have a lot of material now to think about. On this last point i strongly disagree, i think the understanding of the nature of time should be central in understanding the context in which we live and i think there is much more to be discovered and described than just a mathematical use of it.

Honestly i don't think lenght exists outside our brain. The problem i can't understand is how can time be something, like it must have a composition in order to exist, it must be made of something right ?

Thanks, i understand what you mean and it's something i haven't considered too much. What are your opinions on the composition orthe structure of time ?

Greetings to everyone, i am new here so please excuse any errors i did in posting this thread. ( Please also excuse my english ). First off i would like to say i am just a young science lover with no deep understanding of anything in physics, which i love and try to explore in every way possible. One concept i've always been interested in is time. Initially, as everyone i suppose, i viewed time as an absolute and costant background in which events happened. After reading many books about Einstein and the theories of relativity my newtonian view changed and time started for me being "something", i immagined time as a texture of reality and of space (to be honest i could'nt immagine time existing without space, which i always represent, probably in a wrong way, in my mind as made of Calabi–Yau extra dimensions described by string theory ). In the past couple of years however, i started questioning the existence of time itself : 1) How can time be described without movement or changes ? A white ball in a black space with nothing else made for me impossible to describe time if not as a curvature of the einstein fabric of space-time. I would need 2 balls to describe time properly by having reference points. 2) If time exists, it would need to be composed of something let's say a particle which i call "Timeon". Well that particle of time would need to exist in a time in order to be described as existing. How can that happen ? The same thought can be applied when viewing time in the Einstein way. Seems to me now that time dosen't exist, it is just a model which our brain uses to describe changes. This would mean Einstein and its incredibly empirically proven theories would be a wrong description of something else , which is a big sentence to say and one aspect i can't resolve. What am i missing? Sorry for any blasphemy i might have said, i am just trying to understand.
