Over billions of years, the area that is now the Grand Canyon transformed from tall mountains to a flat plain and was later uplifted by tectonic activity. Around 12 million years ago, the Colorado River was dammed and formed a huge lake, Lake Bidahochi. Around 5.5 million years ago, the river reconnected in a new channel and began cutting through the plateau, forming the Grand Canyon over millions of years of erosion from water and weathering. The Grand Canyon continues changing today through ongoing erosion.
World's Largest Cave Discovered In Vietnam
Son Doong cave (in Vietnamese: Hang Sơn Đoòng, meaning Mountain River Cave)
is a cave in Phong Nha-Ke Bang National Park, Bo Trach District, Quang Binh
Province , Vietnam . The cave is located near the Laos-Vietnam border. It has a
large fast-flowing underground river inside.
The cave was found by a local man named Hồ-Khanh in 1991. The local jungle
men were afraid of the cave for the whistling sound it makes from the
underground river. However, not until 2009 was it made known to the public when
a group of British scientists from the British Cave Research Association, led
by Howard and Deb Limbert, conducted a survey in Phong Nha-Ke Bang from April
10-14, 2009. Their progress was stopped by a large calcite wall. According to
Limbert, this cave is five times larger than the Phong Nha cave, previously
considered the biggest cave in Vietnam .
The biggest chamber of Son Doong is over five kilometers in length, 200 meters
high and 150 meters wide. With these dimensions, Son Doong overtakes Deer Cave
in Malaysia to take the title of the world's largest cave.

The chapter is an autobiographical account where she traveled to the end of the earth i.e. Antarctica. The place does not have any humans, life is impossible there. She traveled with high school students on a Russian Vessel. She said that if one needs to or wanted to understand the past, present, and future of our planet he or she needs to start its journey from the end.
Is Genesis' flood story scientifically possible?
The biblical story is similar to a much older Mesopotamian flood story in the epic of Gilgamesh. recently scientists have started to uncover evidence that Noah's flood may have a basis in some rather astonishing events that took place around the Black Sea some 7,500 years ago.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Grand Canyon
277 miles long
18 miles across at its widest
more than 1 mile deep

4. Scientists have been studying the Grand
Canyon for years, trying to answer that very
question.
They may be getting close.

2 billion years ago, this area of Arizona was covered with mountains.
Some of the peaks reached 6 miles in height.
6. Royal Belgian Institute of Natural Science, online, accessed 28 Apr, 2012
Over the next 500 million years, through the action of ice, water and wind, the mountains
gradually eroded away.
What was left was a flat, featureless plain.

Then, between 70 and 50 million years ago, the Farralon Plate shallowly subducted
under the North American Plate.
This was known as the Laramide Orogeny and resulted in the uplifting of the Colorado
Plateau, as well as the growth of the Sierra Nevadas and the Rocky Mountains to the
west and east of it.
8. The Rocky Mountains were steep. With snow runoff and rain, all
of that water needed somewhere to go. Gradually, the Colorado
River was born.
The Colorado River flowed south, down to drain into the Gulf of
Mexico. About 12 million years ago, the path of the river became
blocked. This caused all the waters of the river to drain into a
basin and form a tremendous lake, Lake Bidahochi. (Ribokas, Bob, online, accessed 29
April 2012)
Lake Bidahochi was located about 100 miles east of the modern
day site of the Grand Canyon. The lake contained about 3,000
cubic miles of water, making it larger than Lake Michigan.
9. Ribokas, Bob, online ,accessed 29 April 2012
Meanwhile, the Hualapai Drainage System, which was cut off from the original
route of the Colorado, began working its way around the Kaibab plateau,
towards the huge lake.
Eventually, about 5.5 million years ago, the drainage system reconnected with
the Colorado River.
10. The newly connected channel allowed the lake to
empty to the west.
It is theorized that the rushing of that great mass of
water is what started the downcutting of the gorge that
became the Grand Canyon of today.

A river in flood can dislodge and move great amounts of sediment, all
the way from tiny particles of silt to blocks of rock as large as a house.
The Colorado River today is known to transport 5 tons of sediment
every second, or 300 tons every hour. This is enough to fill 100
Olympic-sized swimming pools. (The History Channel, Netflix online, accessed 24 April 2012)
12. By testing of ancient sand deposits near the start of the
canyon, at Lee’s Ferry, Dr. Karl Karlstrom, University
of New Mexico was able to determine that the rate of
downcutting of the Grand Canyon was about 1 inch
per century. (The History Channel, Netflix online, accessed 24 April 2012)
Since the canyon is about 5300 feet deep, this means
that the Grand Canyon formed as it is today in just
over 5 million years.
13. The Grand Canyon
is not finished.
Everyday, the
material lining the
walls of the canyon
is subjected to
weathering and
erosion through the
action of ice, water
and gravity.
RocScience, online, accessed 30 April 2012
14. (Royal Belgian Institute of Natural Science, online, accessed 28 Apr, 2012)
Millions of years in the future, the Earth’s
search for equilibrium will have flattened
the Grand Canyon to a river and another
flat plain, like the Mississippi.
