The longest tunnel in the world

The longest tunnel in the world is the Gotthard Base Tunnel, stretching an incredible 57 kilometers (about 35 miles) and running from Switzerland to Italy. This engineering marvel was constructed beneath the Swiss Alps and took 17 years to build, opening in 2016. The tunnel is not only the longest but also the deepest traffic tunnel in the world, reaching depths of up to 2,300 meters (7,500 feet) below the mountain peaks. It significantly reduces travel time between northern and southern Europe, making it a vital part of the continent's transportation infrastructu

دنیا کی سب سے لمبی سرنگ

دنیا کی سب سے لمبی سرنگ گوتھارڈ بیس ٹنل ہے، جو 57 کلومیٹر (تقریباً 35 میل) پھیلی ہوئی ہے اور سوئٹزرلینڈ سے اٹلی تک جاتی ہے۔ انجینئرنگ کا یہ عجوبہ سوئس الپس کے نیچے تعمیر کیا گیا تھا اور اسے 2016 میں کھلنے میں 17 سال لگے۔ یہ سرنگ نہ صرف دنیا کی سب سے لمبی بلکہ سب سے گہری ٹریفک سرنگ ہے، جو 2,300 میٹر (7,500 فٹ) تک گہرائی تک پہنچتی ہے۔ یہ شمالی اور جنوبی یورپ کے درمیان سفر کے وقت کو نمایاں طور پر کم کرتا ہے، جو اسے براعظم کے نقل و حمل کے بنیادی ڈھانچے کا ایک اہم حصہ بناتا ہے۔

liquid water discovered on Mars

liquid water discovered on Mars This is the first clear evidence of liquid water, not just frozen ice, discovered on Mars. A groundbreaking discovery published in Science has confirmed that Mars once had liquid water, offering new insights into the planet’s climate and potential for supporting life.  Researchers analyzing data from NASA’s Curiosity rover identified ancient "wave ripples" in rocks at the Gale Crater region, dating back 3.7 billion years. These ripples, formed by wind and water, indicate the presence of a shallow, open-air lake about 2 meters (6.5 feet) deep.  The discovery highlights a time when Mars had a warmer climate and a thicker atmosphere capable of sustaining liquid water — a critical ingredient for life as we know it. This revelation has far-reaching implications for understanding Mars' habitability and planning future missions.  The presence of liquid water raises the possibility that microbial life once thrived on the planet. Additionally, remna...

The black diamond apple stands out from other apples due to its luxurious appeal and rarity and also arouses people's curiosity. The distinctive color of the black diamond apple is actually attributed to the unique geographical location of Ningchi, a small town nestled among the mountains in the Tibet Autonomous Region of China. Apples found at high altitudes are exposed to intense ultraviolet light during the day, causing significant temperature fluctuations. Such climatic conditions contribute to the production of the characteristic black color of the apple. Although the inside of the black diamond apple is like a regular apple...
