10. The Blue Whale – If you’ve ever had the chance to see a blue whale in real life, you’ve been in the presence of the largest creature in the world. They’re also the heaviest thing to ever exist. They used to be all over the oceans until they were hunted to near extinction, before being saved in the 1960s by the international community.

What is the biggest thing in the Earth?
There are several ways to think of the biggest things in the world. The biggest animal is the blue whale, which weighs a quarter of a million pounds. The biggest man-made object is the Burj Khalifa, a skyscraper in Dubai standing 2700 feet tall. The largest rock is Ayers Rock in Australia.
What is the biggest man-made thing in the world?
Tallest freestanding structures on land – Freestanding structures must not be supported by guy wires, the sea or other types of support. It therefore does not include guyed masts, partially guyed towers and drilling platforms but does include towers, skyscrapers (pinnacle height) and chimneys.
(See also history of tallest skyscrapers,) The world’s tallest freestanding structure on land is defined as the tallest self-supporting artificial structure that stands above ground. This definition is different from that of world’s tallest building or world’s tallest structure based on the percentage of the structure that is occupied and whether or not it is self-supporting or supported by exterior cables.
Likewise, this definition does not count structures that are built underground or on the seabed, such as the Petronius Platform in the Gulf of Mexico, Visit world’s tallest structure by category for a list of various other definitions. The tallest freestanding structure on land is the Burj Khalifa in Dubai, United Arab Emirates.
What is the smallest thing ever?
Protons and neutrons make up the core, or nucleus, while teeny electrons cloud about the nucleus. Protons and neutrons can be further broken down: they’re both made up of things called ‘quarks.’ As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
What is bigger than a galaxy?
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
Who is the biggest thing in the universe?
Hint: The biggest thing in the universe consists of a galactic filament and a vast group of galaxies bound together by gravity. So, that object is considered as the biggest supercluster known in the universe. Complete step by step solution: The Hercules-Corona Borealis Great Wall is the Universe’s largest known ‘object.’ This is a ‘galactic filament,’ a massive cluster of galaxies bound together by gravity with a diameter of 10 billion light-years! However, this is not a ‘celestial body,’ which is a term that usually refers to a tightly bound object such as a star or galaxy.
- This object was so big that light takes about 10 billion years to move across this structure.
- When this structure first came to light the researcher team was looking at brief cosmic phenomena known as gamma-ray bursts.
- IC 1101 (with a diameter of four million light-years) is thought to be the largest known elliptical galaxy, and Malin 1 is thought to be the largest known spiral galaxy (with a diameter of 650,000 light-years).
Meanwhile, UY Scuti, a red hypergiant star in the constellation of Scutum with a radius of over a billion kilometers – 1,700 times that of the Sun – is thought to be the largest star by radius. Thus, ‘Hercules Corona Borealis Great Wall’ is the biggest thing in the universe. Note: Many of the world’s largest particle accelerators are dedicated to gaining a better understanding of hadrons, which are subatomic particles made up of two or more quarks. Quarks are among the universe’s tiniest particles, carrying only fractional electric charges.

, a company known for its is currently surveying a block of ocean floor off the coast of Myanmar for Shell. To do so (and to do so quickly), the firm deployed the Polarcus Amani — a massive survey vessel equipped with a record-breaking seismic array.According to, the Polarcus Amani not only boasts the most advanced seismic technology but also a 300-foot-long body that can displace nearly 8,000 tons.
But what makes this vessel (and all the equipment is sports) record-breaking is the in-sea configuration it tows. The vessel’s four propellers (each capable of 3,000 horsepower) provide the power to drag the array of “seismic streamers.” (Photo courtesy of Vimeo/Firegrader) These streamers measure more than a mile wide and 11 miles long. Even more impressive, the survey covers an area of almost 7 square miles at a time — hence why Polarus claimed the record for “largest mobile man-made object.” What do you think of the 8,000-ton machine?

What is the smallest man made object?
The smallest sculpture of a human form ever made posed to scale on a human hair. Credit: Jonty Hurwitz 2014 Technology has long supplied artists with tools they can use to express themselves – even at times giving birth to new art forms. South African artist, engineer and entrepreneur Jonty Hurwitz has used his technical skills to create a form unlike any seen before – and one that can’t even be seen with the naked eye. Jonty Hurwitz 2014 “Trust”, a nano-sculpture of the female figure, is the smallest creation of the human form ever made. It measures about 80 x 100 x 20 micrometres. Just how tiny that is can be seen in the image of the eye of a needle above, but to compare, a human hair is about 100 micrometres thick. An aerial view of “Trust”. – Jonty Hurwitz 2014 It took Hurwitz, who now lives in England, 10 months to produce his tiny artworks through a complex production process. Human models were photographed by 250 cameras rigged up inside a warehouse in Sussex using a technique known as photogrammetry. The making of “Trust” with model Yifat Davidoff. – Jonty Hurwitz 2014 The nano-sculptures were formed at the Karlsruhe Institute of Technology’s Institute of Nanotech in Germany, using a new 3D printing technique called multiphoton lithography in which a polymer resin is hardened by tightly focused zaps of infrared light. In a “clean room” at the Karlsruhe Institute of Technology’s Institute of Nanotech the sculpture are created on a nanoscribe 3D printing machine. – Jonty Hurwitz 2014 A chamber within the printer is filled with light-sensitive polymer. This is zapped with near infrared radiation (NIR) focussed through a microscope. Cupid and Psyche shown kissing to scale on the head of an ant. – Jonty Hurwitz 2014 Another nano-sculpture, “Cupid and Psyche”, shows the miniscule figures of Hurwitz himself along with his nano muse, Yifat. It was inspired by Antonio Canova’s “Psyche Revived by Cupid’s Kiss”, which can be found in the Louvre. This sculpture measures 100 x 90 x 100 micrometres and can sit on the head of an ant. A close-up of Cupid and Psyche on the head of an ant. – Jonty Hurwitz 2014 A third nano-sculpture (below) is called “Intensity”, and features a jumble of female figures that seem to spill and tumble over one another. A nanosculpture about intensity, also called “Intensity”. – Jonty Hurwitz 2014 In a video on his YouTube page, Hurwitz remembers when he first received the package of the finished nano-sculptures in the mail. He could barely get his arms around the box, with smaller and smaller boxes inside, like the layers of a Russian doll nestled in bubble wrap and tape.
Finally, he reached the smallest of the boxes, as small as a jewellery case, and opened it up – to find nothing but a small mirror. He examined it carefully, holding it up to the light. He angled the mirror just so, and at last he saw them – seven small specks, no larger than the dust particles suspended in the air around him, but arranged in a thin straight line.
It wasn’t until he looked through a scanning electron microscope that he could actually see his creations. An aerial view of “Cupid and Psyche”. – Jonty Hurwitz 2014 The story doesn’t end there. Hurwitz, Yifat and a small team of scientists spent hours viewing each of the seven nano-sculptures anchored to the mirror. But when the mirror was taken out of the scanning electron microscope to be rotated at a different angle, tragedy struck – all the nano-sculptures were lost when someone’s finger accidentally pressed against the face of the mirror.
- Hurwitz recalls the denial and shock of having lost what was to him seven of the most precious things ever created.
- But these feelings quickly gave way to something more profound.
- Suddenly I realised, with these nano-sculptures, that they had developed a story.
- Suddenly (they) had taken on a life of their own, a kind of narrative which was always lacking with this sculpture.
“It’s created a story about human desire, it’s created a story of tragedy, it’s created a story of humour It’s created emotion. And in a way, that’s wonderful. Because we love stories.

What is in a universe?
The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. – Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons.
- Along with asteroids and comets, the planets orbit the Sun.
- The Sun is one among hundreds of billions of stars in the Milky Way galaxy, and most of those stars have their own planets, known as exoplanets.
- The Milky Way is but one of billions of galaxies in the observable universe — all of them, including our own, are thought to have supermassive black holes at their centers.
All the stars in all the galaxies and all the other stuff that astronomers can’t even observe are all part of the universe. It is, simply, everything. The star-forming nebula W51 is one of the largest “star factories” in the Milky Way galaxy. “Star factories” like this one can operate for millions of years.
The cavernous red region on the right side of W51 is older, evident in the way it has already been carved out by winds from generations of massive stars (those at least 10 times the mass of our Sun). The dust and gas in the region are swept around even more when those stars die and explode as supernovas.
On the nebula’s younger left side, many stars are just beginning to clear away the gas and dust. Credit: NASA/JPL-Caltech Though the universe may seem a strange place, it is not a distant one. Wherever you are right now, outer space is only 62 miles (100 kilometers) away.
- Day or night, whether you’re indoors or outdoors, asleep, eating lunch or dozing off in class, outer space is just a few dozen miles above your head.
- It’s below you too.
- About 8,000 miles (12,800 kilometers) below your feet — on the opposite side of Earth — lurks the unforgiving vacuum and radiation of outer space.
In fact, you’re technically in space right now. Humans say “out in space” as if it’s there and we’re here, as if Earth is separate from the rest of the universe. But Earth is a planet, and it’s in space and part of the universe just like the other planets. This true-color image shows North and South America as they would appear from space 22,000 miles (35,000 km) above the Earth. The image is a combination of data from two satellites. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Terra satellite collected the land surface data over 16 days, while NOAA’s Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth’s clouds and the Moon.
How big is the universe?
|The Hubble Ultra-Deep Field image shows some of the most remote galaxies visible to present technology (diagonal is ~1/10 apparent Moon diameter)|
|Age (within ΛCDM model )||13.787 ± 0.020 billion years|

The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy, The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together 13.787 ± 0.020 billion years ago, and the universe has been expanding ever since the Big Bang.
- While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
- Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center.
Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System, In developing the law of universal gravitation, Isaac Newton built upon Copernicus’s work as well as Johannes Kepler ‘s laws of planetary motion and observations by Tycho Brahe,
- Further observational improvements led to the realization that the Sun is one of a few hundred billion stars in the Milky Way, which is one of a few hundred billion galaxies in the observable universe.
- Many of the stars in a galaxy have planets,
- At the largest scale, galaxies are distributed uniformly and the same in all directions, meaning that the universe has neither an edge nor a center.
At smaller scales, galaxies are distributed in clusters and superclusters which form immense filaments and voids in space, creating a vast foam-like structure. Discoveries in the early 20th century have suggested that the universe had a beginning and that space has been expanding since then at an increasing rate.
- According to the Big Bang theory, the energy and matter initially present have become less dense as the universe expanded.
- After an initial accelerated expansion called the inflationary epoch at around 10 −32 seconds, and the separation of the four known fundamental forces, the universe gradually cooled and continued to expand, allowing the first subatomic particles and simple atoms to form.
Dark matter gradually gathered, forming a foam -like structure of filaments and voids under the influence of gravity, Giant clouds of hydrogen and helium were gradually drawn to the places where dark matter was most dense, forming the first galaxies, stars, and everything else seen today.
- From studying the movement of galaxies, it has been discovered that the universe contains much more matter than is accounted for by visible objects; stars, galaxies, nebulas and interstellar gas.
- This unseen matter is known as dark matter ( dark means that there is a wide range of strong indirect evidence that it exists, but we have not yet detected it directly).
The ΛCDM model is the most widely accepted model of the universe. It suggests that about 69.2% ± 1.2% of the mass and energy in the universe is dark energy which is responsible for the acceleration of the expansion of space, and about 25.8% ± 1.1% is dark matter.
- Ordinary (‘ baryonic ‘) matter is therefore only 4.84% ± 0.1% of the physical universe.
- Stars, planets, and visible gas clouds only form about 6% of the ordinary matter.
- There are many competing hypotheses about the ultimate fate of the universe and about what, if anything, preceded the Big Bang, while other physicists and philosophers refuse to speculate, doubting that information about prior states will ever be accessible.
Some physicists have suggested various multiverse hypotheses, in which our universe might be one among many universes that likewise exist.
What is the fastest thing in the universe?
So light is the fastest thing. Nothing can go faster than that. It’s kind of like the speed limit of the universe.
Is space infinite?
Tanya Hill, Astronomer – yes – There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
The observable universe is centred on us. An alien in a galaxy far away would have its own observable universe. While there may be some overlap, they would inevitably see regions we can’t see. Therefore, it’s not possible to see if the universe is finite, because we can’t see it all. Instead, we can tackle this question by exploring the universe’s shape.
25 Largest Animals Ever Caught On Camera
While we don’t know the shape of all space, we do know our part of space is flat. This means two rockets flying parallel on cruise control will always remain parallel. Because space isn’t curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever.
But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape. Therein lies the problem. Additionally, there are many ways the universe could have been curved, but instead we live in a region of flat space. This is a very specific condition and we use a theory called “inflation” to explain it.
Inflation is the idea that very early on the universe rapidly expanded for a brief moment, smoothing out all the kinks and curvatures in our part of space. After inflation, the universe grew to what we see today. But it’s possible inflation didn’t just seed our universe.
What is the biggest black hole?
Home News Science & Astronomy
Astronomers discovered the largest black hole ever seen thanks to its ability to bend light. (Image credit: ESA/Hubble, Digitized Sky Survey, Nick Risinger (skysurvey.org), N. Bartmann) Astronomers have just discovered what may be the largest black hole known to date.
The giant black hole has a mass of 30 billion suns and sits at the center of a galaxy located hundreds of millions of light-years from Earth. Astronomers call the cosmic monster an ultramassive black hole, as opposed to the usual galactic supermassive black holes that weigh anywhere between a few million to a few billion solar masses.
Astronomers discovered the black hole during observations of a galaxy located farther away from Earth than the one centered around the monster black hole, while using the gravity of the foreground galaxy to magnify the background object. This effect, known as gravitational lensing, is a result of gravity bending the light around extremely massive objects.
- Serving as nature’s own telescope, gravitational lensing frequently helps astronomers to increase the magnification of objects too distant to be properly visible to human-made telescopes.
- Related: Black holes may be swallowing invisible matter that slows the movement of stars “This particular black hole, which is roughly 30 billion times the mass of our sun, is one of the biggest ever detected and on the upper limit of how large we believe black holes can theoretically become, so it is an extremely exciting discovery,” James Nightingale, an astrophysicist at Durham University in the U.K.
and lead author of the new study, said in a statement (opens in new tab), The team arrived at the size of the black hole by analyzing the magnification of the foreground object in a series of images taken by the Hubble Space Telescope, Using sophisticated computer modeling, the scientists were able to simulate how much light bends around the foreground galaxy where the black hole resides.
- They tested thousands of black hole sizes before arriving at a solution that matched the observations.
- The black hole, located in one of the galaxies of the Abell 1201 galaxy cluster, is the first discovered using this technique.
- Although enormous, the black hole is not very active, meaning it’s not swallowing too much material and therefore not producing strong X-ray radiation.
Such black holes are nearly impossible to study by other methods. “Most of the biggest black holes that we know about are in an active state, where matter pulled in close to the black hole heats up and releases energy in the form of light, X-rays, and other radiation,” Nightingale said.
- However, gravitational lensing makes it possible to study inactive black holes, something not currently possible in distant galaxies.
- This approach could let us detect many more black holes beyond our local universe and reveal how these exotic objects evolved further back in cosmic time.” The findings (opens in new tab) were published on Wednesday, March 29, in the journal Monthly Notices of the Royal Astronomical Society.

How big is a black hole?
Stellar-mass black holes are typically in the range of 10 to 100 solar masses, while the supermassive black holes at the centers of galaxies can be millions or billions of solar masses. The supermassive black hole at the center of the Milky Way, Sagittarius A*, is 4.3 million solar masses.

What is the biggest star?
- Science & Astronomy
The biggest star in the universe makes our sun look tiny speck. (Image credit: dottedhippo via Getty Images) The biggest star in the universe (that we know of), UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun.
To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti. Our sun is enormous — more than a million Earths could fit inside of it. But on a stellar scale, it could be swallowed up by about half of all stars observed so far — especially stars like UY Scuti.

What’s bigger than the universe?
Final Thoughts – As it stands, the universe is the largest object that we are aware of. There is nothing larger, and everything we can smell, hear, taste, touch, or see is a part of it. From the air we breathe to the most distant star, these objects exist within our universe.
What object is bigger than the Earth?
By far the largest and most massive object in the Solar System is the Sun. The Sun has a diameter of 1,390,000 km. In comparison, the Earth’s diameter is only 12,742 km. The Sun is vastly larger than the Earth.
