    What is the largest flat top mountain in the world?

     There are many mountains in the world that have a “table top” structure. I will focus on two candidates for the title of the largest flat top mountain in the world.

    Mount Roraima: English explorer Sir Walter Raleigh first described this mountain during his expedition to the area in 1596. It is located at a tripoint of three countries: Venezuela/Brazil/Guyana. The mountain’s summit area is defended by 400-metre-tall cliffs on all sides. Its total height is 2,810 m, and its summit surface area is 31km². In short a massive table top mountain.

    Here is another view of the top:

    Since I posted this answer , there have been many comments about what the top looks like. Here are two photos from World’s Great Wonders by Jheni Osman, that gives readers some inkling what the top looks like:

    There is no evidence that pterodactyls or other ancient beast lived on the plateau. Of course the plateau is home to many plant species found nowhere else on Earth. These endemic plants and small animals have developed and are unique to the area.

    The second candidate is Table Mountain, Cape Town, South Africa: The table top is 1,086 metres (3,563 ft) above sea level. The length of the “ table” is approximately three kilometres (2 miles). The pic below is the front view as seen from the waterfront area of Cape Town.

    Table Mountain is certainly not as high as Mount Roraima, and as far as I can tell from my visits the “flat top” does not exceeds 31 square kilometers. Thus Mount Roraima takes the prize as the largest table top mountain.

    But what is clear is that anyone can readily get to the top of Table Mountain via cable car, or you can hike up, which I have done. Here is part of the Smuts trail that starts in Kirstenbosch Gardens that I took:

    It takes about 1.5–2hrs to reach the top.

    In contrast to get to the top of Mount Roraima requires serious climbing with professionals.

    The view from the top of Table Mountain is spectacular. Here is a view from the Top of Table Mountain, with Cape Point in the distance. Note the dam/reservoir on the top of Table Mountain. This pic was taken near Maclear's beacon, the highest point on Table Mountain

    Our hike started in Kirstenbosch Gardens following the Smuts trail. Here is a view of Cape Town and Signal Hill from the Top:

    And finally a view of Camps Bay on the Atlantic side

    So in summary Mount Roraima is the largest flat top mountain the world based on height and the expanse of its table top, but Table Mountain though second in size and height can be readily experienced by all, either by hiking or taking the cable car to the top!

    The largest and deepest natural funnel on Earth

     The largest and deepest natural funnel on Earth is called Xiaotsai Tiankan.

    It is located in the center of China, Penzhi. This amazing funnel is completely natural and measures 662 meters deep and 537 meters wide. But the most impressive thing is the diversity of life it contains.

    Geologists are surprised by the influence of water on Xiaotsai Tiankan. A funnel was formed at the top of the cave, where an 8.5 kilometer long underground river falls into a beautiful waterfall. Thanks to its huge size it is the deepest karst funnel in the world.

    It is home to about 1,300 species of plants and wild animals. Among the most interesting inhabitants of the underground forest is the misty panther, known to the locals since ancient times.

    What is the largest star in space?

     We will never know the largest star in space. We can only tell you what is the largest star discovered to this date. The Universe is simply too vast to say that what “WE” found is the largest star in space.

    That is Stephenson 2–18

    Stephenson 2-18 (St2-18) is a red supergiant located in the constellation Scutum. Also catalogued as Stephenson 2-DFK 1 and RSGC2-18, it is the current record holder for the largest star known, with a size 2,150 times that of the Sun.

    How big is Stephenson 2-18, among the largest stars in the known universe? It would take earth's fastest jet over 500 years to travel around. It would take almost 9 hours at the speed of light. Its circumference equals the orbit of Saturn.

    The star is located at a distance of 18,900 light years from Earth. It is a member of the open cluster Stephenson 2.

    So, as our telescopic technology or any revolutionary technology, let us pear deeper into space this we will find out that there are stars even bigger than Stephenson 2–18. It's just a matter of time and innovation.

    What is the largest object in the universe?

     If you mean a singular object instead of clusters of stars (galaxies) or clusters of galaxies (superclusters), then I will provide my list (that we know of so far):

    Largest non-spherical solid object: Haumea - 620 km radius.

    Largest moon: Ganymede - 2634 km radius.

    Largest rocky planet: Kepler 10 c - 2.35 Earth radii (15,000 km).

    Largest gas giant planet: HD 100546 b - 6 Jupiter radii (419,466 km).

    Largest ring system: J 1407 b - 0.6 AU radius (90 million km).

    Largest star: UY Scuti- 1708 Solar radii (1.19 billion km).

    Largest black hole: TON 618 - 1300 AU radius (194.5 billion km).

    Largest (mostly intact) nebula: LAB-1–300,000 light year diameter.

    As mentioned before, as a bonus:

    Largest galaxy: IC 1101- 3.92 million light year diameter.

    Largest structure: Hercules-Corona Borealis Great Wall - 10 billion light year diameter.

    UPDATE 2020:

    Stephenson 2-18 is now considered to be among the largest known stars, if not the largest, with a radius of 2,158 solar radii. UY Scuti on the other hand is about 1,700 times greater than the radius of the sun. It is also among the most luminous cool supergiant stars, with a luminosity of 440,000 solar luminosity.

    Update 2023:

    The largest black hole discovered so far is Phoenix A from the Phoenix Cluster. It is around 100 billion times the mas of the Sun and has an astounding radius of around 1950 Astronomical Units (295.25 billion kilometers).

    What is the largest galaxy in the known universe?

     THE ALCYONEUS GALAXY

    Astronomers just found the largest galaxy ever discovered, and they have no idea how it got so big.

    At 16.3 million light-years widethe Alcyoneus galaxy has a diameter 160 times wider than the Milky Way and four times that of the previous title holder, IC 1101, which spans 3.9 million light-years, researchers reported in a new study. Named after one of the mythical giants who fought Hercules and whose name means "mighty ass" in Greek, Alcyoneus is roughly 3 billion light-years from Earth.

    The galactic monster is a particularly large example of a radio galaxy, or a galaxy with a supermassive black hole at its center that gobbles up enormous amounts of matter before spitting it out in the form of two massive jets of plasma moving at near-light speed. The plasma beams slow down after traveling millions of light-years, spreading out into plumes that emit light in the form of radio wavesThe lobes of Alcyoneus are the largest ever discovered.

    Galaxies with massive, plasma-filled radio lobes aren't uncommon (the Milky Way has two small plumes), but scientists are baffled as to how Alcyoneus, a relatively ordinary galaxy at its core, was able to grow such monstrously huge plumes.

    Apart from its massive plumes, Alcyoneus is a typical elliptical galaxy, with a total mass roughly 240 billion times the mass of the sun (half that of the Milky Way) and a central supermassive black hole 400 million times the mass of the sun (100 times less massive than the largest black hole).

    In fact, Alcyoneus' center is small in comparison to the centers of most radio galaxies.

    What is the largest structure discovered so far in the known universe?

     The largest known structure in the Universe is called the 'Hercules-Corona Borealis Great Wall', discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.

    The Hercules–Corona Borealis Great Wall[1][5] or simply the Great Wallis the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter). This massive superstructure is a region of the sky seen in the data set mapping of gamma-ray bursts (GRBs) that has been found to have an unusually higher concentration of similarly distanced GRBs than the expected average distribution.

    It was discovered in early November 2013 by a team of American and Hungarian astronomers led by István Horváth, Jon Hakkila and Zsolt Bagoly while analyzing data from the Swift Gamma-Ray Burst Mission, together with other data from ground-based telescopes.[2][3] It is the largest known formation in the universe, exceeding the size of the prior Huge-LQG by about two times.
