limitations

A website has collected more than 1,000 speed limitations on Spanish trains. Adif has knocked her down

by

They are called Dignitat a les Vies and they say they are “fed up with the mistreatment by Renfe, Cercanías and Adif.” The claim is clear: “we want a decent railway system.” And as a means of protest they had a website with all the speed limitations found on Spanish railways. They had it, because Adif has taken down the website. Cessation of activity. It is the title that heads a writing from Dignitat a les Viesa platform that until last Friday had an active web page in which all the speed limitations of Spanish railways were collected. The text reads that Adif has confirmed that the blocking of the page is derived from a previous complaint on its part, understanding that “the information on Temporary Speed ​​Limits (LTV) is ‘sensitive’ and cannot be known by the general public.” Listening to the road manager, the court has ordered the blocking of the website. What was shown? Simply, all the speed limitations present on Spanish roads. Supported by users and, above all, by machinists according to The Country, The association had a map where more than 1,000 incidents were recorded. The map, which Dignitat a les Vies assures has been replicated by the media (such as its own The Country) and has not been removed, showed public information that Adif refuses to provide in what they describe as “an act of paternalism. According to these users, “Adif is failing to comply with the current legal framework. In accordance with Law 9/2025 on Sustainable Mobility, Regulation (EU) 2017/1926 (MMTIS) – updated by 2024/490 – and Directive (EU) 2019/1024”, which requires them to make public “the data on the infrastructure and its restrictions.” And they emphasize that showing them “helps the user understand chronic delays.” The restrictions. As reflected in the newspaper The CountryIn Spain there are currently more than one mile of temporary speed restrictions active. This means that there are more than 1,000 points where drivers must circulate at a speed lower than the maximum speed permitted at that point in a generic manner. These restrictions are a consequence of actions on the tracks but also the consequence of continuous warnings by train drivers. And it is that, as they have confirmed to Xatakathe workers indicate with a report points that, in their opinion, should be reviewed or do not allow driving at the maximum speed required. Everything indicates that, after the Adamuz accident in Córdobathe zeal with these notices is greater than before. Train drivers also have the power to reduce speed at specific points if they so deem it necessary. These speed reductions must be reflected with a notice to the command post and in a report but, as we said, Adif has the final say on what is reviewed, what point is left for later and where speed restrictions are applied and for how long. Is it important? Yes, because temporary speed restrictions have multiplied high-speed travel time. Right now, Adif has indicated to the operators that Journey times are going to be longer in Madrid-Barcelona due to actions on the tracks and trains have been eliminated. This situation will last for months and as it is an issue that falls on the side of the road manager, the client has no right to compensation. The data of The Country They indicated on March 9 that there are 422 points where trains must run at a maximum of 30 km/h. It is the most repeated speed limitation. If the restrictions at 60 km/h or less are added, there are more than 850 points in Spain where high-speed trains cannot go above this speed. Where are there more limitations? Due to the volume of traffic and passengers, it is logical that the restrictions in Madrid-Barcelona have focused attention. Especially since it has been difficult to travel between both cities during the day without suffering any surprises or being clear about what time you are going to arrive, which complicates the traditional movement between cities. However, the media reports that line 100 Madrid-Hendaya is the most affected with 83 temporary speed limitations that reduce speed by 112 kilometers along the total 641 kilometers, followed far away by line 400 Alcázar de San Juan-Cádiz, which totals 85 limited kilometers spread over 69 restrictions found along 577 kilometers. However, it is the line 240 S. Vicenç Calders-L’Hospitalet that is most affected if the number of kilometers with active speed limitations is taken into account. And of the total 71 kilometers of the line, 56 of them have limitations below normal as a result of 35 conflict points.

If we don’t see aliens it is because of our “epistemological limitations”

by

What if aliens are everywhere, but we are cognitively unable to perceive them? A Serbian philosopher has proposed a disturbing solution to the Fermi paradox: The answer is not in the universe, but in the limits of our own brain. Where is everyone? The Fermi Paradox is one of the most famous questions in modern science. The universe is immense and very ancient. The lights we see in the sky are billions of galaxies and trillions of planets. By mere statistics, intelligent life should be common. If this is so, why haven’t we found the slightest evidence of it? Why haven’t we seen its megastructures, caught its signals or received visitors? “Where is everyone?” physicist Enrico Fermi asked in 1950. The Great Filter. There are many brilliant minds who have dared to use the Fermi Paradox. Many of the answers fall under what has come to be known as “The Great Filter”: something that prevents the development of a higher level civilization in the Kardashev scale. Perhaps advanced civilizations tend to annihilate themselves in nuclear wars, or perish in the face of lethal climate change before they can colonize the galaxy. Perhaps the conditions that allowed life here are an unrepeatable cosmic coincidence. We are alone because we are a rare bird. The ego can get us. All of these solutions have a root problem: they are deeply anthropocentric. They assume that other intelligent life forms are like us, that they use technology that we can detect. What if the great silence of the cosmos was nothing more than the result of searching for radio signals when the intelligent life we ​​seek communicates across dimensions we cannot even imagine? We are dumb as worms. This is where the proposal of the Serbian philosopher Vojin Rakić, published in the International Journal of Astrobiology. Rakić calls it the “solution to enduring human epistemological limitations.” The key is in the term “epistemological”, which in the theory of knowledge is how we know what we know and what the limits of our perception are. Extraterrestrial life could be so radically different from us that it simply our brain is not equipped to recognize it. We are to aliens what worms are to us. So? Well, if Rakić is right, there isn’t much to do. We look for little green men in flying saucers, but intelligent life could exist as a form of non-physical consciousness, an interdimensional energy network, or an intelligence based on dark matter. Rakić uses very powerful terrestrial analogies. We know that octopuses are incredibly intelligent, but their nervous system is completely foreign to ours. Fungal networks demonstrate a complexity that goes unnoticed by us. And few would have imagined that a handful of silicon chips would give rise to AI. How can we explain to someone from a couple of centuries ago that we have taught stones to speak? SETI is already at it. This idea, which might seem like pure philosophy, is catching on in the scientific community. The Search for Extraterrestrial Intelligence Institute (SETI) itself has made an appeal to “abandon the anthropocentric perspective” in their exploratory work. It is not about stopping searching, but about expanding our definition of life and intelligence, thinking that “other minds” might have nothing to do with terrestrial biology. For now, our best weapon to stop being dumb as worms is to advance our own science and improve our own cognition. Image | NSF/NSF NRAO/AUI/B.Foott
