De la istoricul Herodot se știa cum s-au construit piramidele: nu au fost extratereștrii, ci zeci de mii de sclavi care munceau, pentru o piramidă, 20 de ani! Foloseau rampe și alte mecanisme inginerești ale vremii lor, pentru a urca și pune blocurile de piatră unul peste altul. Dar cum ajungeau blocurile de piatră, masive, acolo, de la mari distanțe? Recent, arheologii americani au găsit răspunsul: folosind un braț maritim al fluviului Nil, necunoscut până acum. Privit aici harta. În dreapta este Nilul. Linia albastră, punctată, din stânga este locul prin care, acum cinci mii de ani, trecea un braț al Nilului. Remarcați cum acesta trecea pe lângă locurile unde s-au construit cele mai mari piramide. Ei bine, pe el erau transportate marile blocuri de piatră și alte lucruri necesare constructorilor. Brațul a secat de atunci, iar urmele lui sunt ascunse în terenurile agricole de azi. Arheologii le-au găsit folosind săpături specifice și măsurători din satelit. Se poate ca de-a lungul acestui braț de apă, azi secat, să existe și alte construcții ascunse în pământ. Desigur, poate să scrie Herodot ce vrea și arheologii moderni să găsească orice, asta nu va opri niciun conspiraționist să pretindă că piramidele au fost construite de extratereștri”

#stiinta #fizica #science #tehnologie #technology #cristianpresura Știai că cel mai mare deșert din lume conține cea mai mare parte a apei dulci de pe planetă? Antarctica este considerată un deșert deoarece practic nu are precipitații. Dar ca Muntele Fuji de langă Tokyo a erupt ultima dată în 1707? Cutremurele și tsunami-ul care au urmat au ucis 30.000 de persoane, iar câmpurile de orez au rămas sterile timp de 100 de ani. Un tsunami este un val masiv care se revărsă peste uscat și distruge totul în calea sa. Poate avea 30 de metri înălțime când lovește țărmul. Știai că fosile marine sunt adesea găsit pe vârfurile înalte ale munților. De ce? Pentru că multe vârfuri de munte au fost odată pe fundul mărilor, iar apoi împinse în sus de mișcările maselor de pământ. De exemplu, eu am văzut fosile de corali marini pe vârful Buila, din județul Vâlcea.Tu ai văzut așa ceva?

Știai că Jupiter este de două ori mai mare decât toate celelalte planete din Sistemul Solar combinate? C durează puțin sub 10 ore terestre. Jupiter nu are o suprafață stâncoasă; dacă ai arunca un obiect din vârfurile norilor, acesta nu ar “ateriza” niciodată. Forța gravitațională a lui Jupiter este atât de puternică, încât afectează traiectoriile cometelor și ale asteroizilor. Planeta este faimoasă pentru Marele Punct Roșu, o furtună gigantică mai mare decât Pământul care are cel puțin 300 de ani vechime. Jupiter are aproape 100 de sateliți naturali și un sistem de inele, descoperit de sonda Voyager Pe Jupiter nu există anotimpuri. Planeta nu se înclină suficient de mult pe axa sa, pentru a produce diferențe de temperatură în timpul anului. Tu ce ai vrea să vizitezi dacă ai merge la Jupiter?
Join Ariane 6 launch system architect, Tina, as she shows us a day in her life.
Tina has worked on space transport systems for 20 years now. She first worked on the Automated Transfer Vehicle (ATV), then on the Ariane 5 Mid-life Evolution development and now on Europe’s newest launcher Ariane 6.
How did she become a rocket scientist?
“I was lucky enough to spend some months in French Guiana as a student for an internship and working there got me hooked – I was determined to come back for my job one day, and here I am: I spent a great part of 2023 in Kourou testing the Ariane 6 propulsion system, together with an amazing team of very skilled professionals.
I consider myself extremely lucky to have a job and colleagues that make me want to get out of bed and into the office every day – because we love what we do and because the people are simply amazing!”

🚀 Have you ever wondered how we transport rockets?
All the elements that make up Ariane 6 are manufactured in mainland Europe and then transported by this ship, named Canopée.
It is the first custom-built transporter to use sails, reducing emissions and saving on fuel by up to 30%, and on this trip, it travels for 10 days covering over 7000 km to reach Europe’s Spaceport in French Giuana.
The hybrid-propulsion vessel is 121 m long and has 37 m tall sails. Canopée rotates continuously between stop-offs to load each Ariane 6 stage and other parts and ship them across the Atlantic Ocean to Europe’s spaceport.

Aurora made a rare appearance across both the Northern and Southern Hemisphere skies after Earth was hit by one of the strongest geomagnetic storms for years. The storm over the weekend was classed as the highest G5.
Don’t worry if you missed them, we are entering a “solar maximum” where the Sun becomes very active meaning more storms and a greater chance of seeing Aurora in more places.
Let us know if and where you saw them in the comments👇

#stiinta #fizica #science #tehnologie #technology #cristianpresura “Ce vedem aici este o “ploaie solara”! In partea de jos este suprafata Soarelui. In partea de sus este atmosfera Soarelui, denumita si corona sau coroana, in termeni populari. Doar ca amosfera Soarelui, care se intinde pe milioane de kilometri, este facuta din plasma, in cazul de fata un gaz puternic ionizat. Asta se vede foarte bine in pozele cu eclipse de Soare. Plasma, din care este facut atmsofera Soarelui, ascunde un mister: temperatura ei este de milioane de grade Celsius, desi suprafata Soarelui are doar 6000 de grade Celsius. Cum se poate?In mod normal, cand ne indepartam de foc, temperatura scade.iata misterul nerezolvat! In imagine vedem cum plasma din atmsofera se raceste si cade apoi catre suprafata Soarelui, in linii luminoase, despre care se crede ca urmeaza liniile de camp magnetic. Mai vedem pe suprafata Soarelui tot felul de structuri ce fac parte din cromosfera, care este partea de jos a atmsoferei Soarelui, de doar cateva mii de kilometri inaltime. Cromosfera este interfata dintre Soarele ce “bolboroseste” si atmosfera lui. Aici se initiaza eruptiile solare. Un lucru e cert daca privim din nou aceasta “ploaie” de pe Soare: nu ne va racori! “
A group of 12 volunteers are sticking to a strict bed routine for 60 days, lying with their feet up and one shoulder always touching the mattress. This reclined lifestyle includes meals, showers and toilet breaks, as well as intensive cycling and centrifuge rides for some.
The BRACE study follows a two-month bedtime schedule to investigate how cycling and artificial gravity could counteract changes the human body experiences in space.
Astronauts face similar physiological problems as elderly and bedridden patients on Earth. During space missions, astronauts’ bodies go through a wide array of changes – everything from their eyes to their heart might be affected, and their muscles and bones start to deteriorate. To battle this degradation, crew members exercise two hours per day on the International Space Station.
The BRACE study involves male participants between the ages of 20 and 45 years with good physical and mental health. They are placed in beds tilted 6° below the horizontal position. As blood flows to the head and muscle wears out from lack of use, researchers chart how their bodies react.
Researchers split the volunteers in three groups. One group cycles in bed, a second one cycles while being spun on a centrifuge, and a third control group stays in bed for the full two months with no bike exercise or centrifuge rides. The centrifuge mimics artificial gravity, acting on all organs at once. Volunteers are spun to drive blood towards their feet, where the force of gravity doubles during the ride. Scientists hope artificial gravity could be used to keep astronauts fit and healthy in space.
Now halfway through its second edition, the experiment will finish on 4 May 2024, after 95 days of intense clinical testing and monitoring. This campaign takes place at MEDES, the Institute for Space Medicine and Physiology in Toulouse, France, and is supported by the French Space Agency CNES.
The study involves 14 European and international science teams that are working to release the results from the first BRACE campaign in 2023. Researchers are assessing a wide range of changes in the cardiovascular, metabolic, musculoskeletal, neuro-sensorial, haematological, and immunological systems.
The tests will provide a better understanding of the effects of prolonged bedrest to the benefit of those in space and on Earth. Results could help design countermeasures and improve health for patients suffering from accelerated ageing due to a sedentary lifestyle.
Get ready for a magnetic overload with Science Max! This compilation is bursting with electrifying experiments and surprising science facts.
