General facts that are no longer true

Everything undergoes gradual transformation. Even the general facts you previously believed to be true about reinforced concrete could alter over time. There are also some things you learnt in school that weren’t entirely right because the truth can be considerably more convoluted than a pupil can comprehend. The information that has either changed over time or was given to you improperly during your education is listed below.

1. The Great Wall of China is the only human creation that can be seen from space

Now, in fact, there are many such objects. Rumours that the Wall of China can be seen not only from a spacecraft but even from the Moon date back to 1938. In 2003, the first Chinese astronaut debunked this myth.

He said that the Great Wall is visible from space only under certain conditions, and in addition to it, you can see major highways, bridges, airports, and much more. But nothing is visible from the moon—only a white-blue sphere. We examine the most amazing places on earth that can be seen from space, including the largest rivers and mountains on the globe as well as historic pyramids.

I have a list of a few that can be seen from space: the Himalayas, the Great Barrier Reef, the Amazon River, Palm Island, Dubai, the Ganges River Delta, the Great Pyramids of Giza, the USA’s Grand Canyon, Australia’s Great Barrier Reef, and Egypt’s Great Pyramids.

2. No one can fold a piece of paper in half more than 7 times

It’s a frequent misconception that you can only fold a piece of paper in half seven times. That might be correct for a piece of paper with typical A4 sizes, but mathematician Britney Gallivan, a US teenager at the time, asserts that the largest number of folds is actually influenced by the sheet’s original size.

How many times could you fold a sheet of paper the size of the observable universe? asks Jack Baker of the University of Leicester in the UK. American students have used toilet paper to dispel this notion.

Students at St. Mark’s School have amassed 16 kilometres of toilet paper and excruciating patience, according to their math teacher, James Stuart Tanton. They folded the paper 13 times in seven hours. Watch the video:

3. The Egyptian pyramids built by slaves

The pyramids were built by Egyptian labourers. The belief that slaves built the pyramids is supported by culture. However, subsequent archaeological discoveries demonstrate that the pyramids were originally constructed by the Egyptians themselves.

the pyramids were built by slaves,
What do you thing that How Pyramids built ? — **What do you thing that How Pyramids built ?**

The labourers were from underprivileged backgrounds. They received crypts close to the pyramids because of their great respectability. That is not how slaves would be handled.

4. Witches burned at the stake in Salem

In actuality, they were hanged. You must have known that the Salem residents burnt the witches at the stake even if you haven’t read Arthur Miller’s The Crucible. Richard Trask, an archivist, claims that it didn’t actually happen that way.

Witchcraft was then a crime punishable by hanging as opposed to being burned at the stake. Witchcraft, however, was regarded as heresy in Europe, and individuals who practised it were burnt at the stake. Maybe that’s where the misunderstanding began.

5. America gained Independence on July 4th, 1776

. America gained independence on July 4, 1776

Seven years later, in 1783, America formally declared its independence. Americans celebrate Independence Day in a huge way on July 4 every year. Although the Treaty of Versailles was ratified on September 3, 1783, America was not yet free from British dominion, despite the Declaration of Independence’s signing on July 4, 1776. America attained independence at that time.

5. Pluto is a Planet

Pluto, however, is not a planet. The possibility of a ninth planet has been understood since the late 1800s. Percival Lowell, an astronomer, even began an investigation to find the enigmatic “Planet X” in 1906. Clyde Combo started taking pictures of the stars in the constellation Gemini in 1929, which is where “Planet X” was thought to be.

Pluto was found and elevated to planet status in 1930. Pluto was moved to the category of minor planets when Eris, which turned out to be the most massive trans-Neptunian object, was discovered in 2005.

6. A Diamond is the hardest substance

Diamond is the hardest substance, Diamond is not the hardest material — **Diamond is not the hardest material**

The nanomaterial made of boron nitride is now tougher than diamond. A unique nanomaterial based on cubic boron nitride microcrystals has been developed by Chinese and American physicists that is superior to diamonds in terms of hardness and other properties.
