Largest Flying bird

The largest flying bird to ever exist as far as we know is the Argentavis magnificens, they were loosely related to Eagles but belonged to their own group. They were known to stand as tall as an adult human and have a wingspan of 8 meters. 
They were a predator and probably hunted other birds and mammals. If you saw one flying today, it would look like a paraglider or a small airplane. The family group they were a part of is Teratornithidae, they were a group or large eagle like birds that lived in south America.

The Sandy Drowning Theory

There is a well known fan theory associated with the musical movie titled 'Greace'. They think the whole movie is an hallucination of Sandies brain caused by her drowning. 

In the theory, Dan doesn't save her from drowning in the beginning of the movie, that was an hallucination along with all the other scenes in the movie up to the point when they're in a car and it starts to fly to heaven. 
The flying car scene in the theory would be when her oxygen starved brain finally shuts down. It is quite a grim concept and it makes the whole movie hard to view a second time. It adds a grim lens to an otherwise upbeat movie.

Largest Ever Flying Animal

The Largest flying animal to ever exist as far as we know is the Quetzalcoatlus northropi, it was a type of pterosaur. It went extinct at end of the late Cretaceous period, the end of the dinosaur era. It was huge, the creature is thought to weigh about 250 kg and stood about 5 or 6 meters tall when not flying; as tall as a giraffe. 
It not fully understood how they were able to fly but it is thought they would use a spring like muscle contraction to launch itself into the air. The 10 to 11 meter long wingspan would have helped it to stay airborne. 

If it existed today, it would likely be mistaken for a small airplane because of its size.

One Cell Multi Cell

If you ever wondered if there is a life form that lives as a single cell but also can be a multi cell organism, there is one, it's called Dictyostelium discoideum
It is an amoeba (ameba) that lives as a single celled being that consumes bacteria but when there isn't much to eat, individual cells will join together to form a multicellular being (a bit like power rangers when all their robot parts join together). When they are all joined together they can combine their movement to crawl large distances compared to their size. They behave more like a worm or slug than a cellular life form when they are one.

Giant Cell

There is a giant single cell life form that lives at the bottom of the ocean called a Xenophyophorea. They are so big that they can be picked up by hand. They use sediments in the ocean to build their shells known as tests. They live by gathering small particles of other life forms like algi the drift down from the ocean above them. 
Some of these single celled life forms can reach the size of 20cm across, about the size of a football. Although they are one cell they usually have more than one nucleus.

Black holes

It is believed that all objects with mass can become black holes as long as their radius is reduced to a certain size, even individual particles can become black holes. In a book written by professor Brian Cox it pointed out that if the Earth were compressed into the size of a pepple, a few centimetres across, it would be a black hole. 
The same book pointed out that gravity is the weakest force, a small magnet can pull a metal object away from the Earth, but it has no limits, it keeps increasing with mass and can be focused into a small space and cause a sphere around itself with an escape velocity that is higher than the speed of light. In other words, even light can't escape the gravity of a black hole if it gets too close. They call the space where light can't escape the event horizon.

Movie Facts

In the book that the movie 'The thing 1982' is based on titled  'who goes there' by John Campbell. There are some key attributes of the alien creature that was not revealed in the movie. 

Firstly, the organism doesn't need to eat or breathe because it can harness cold fusion in its cells, they split water molecules and merge the two hydrogen atoms together to make helium and lots of energy.  

Secondly, Dr Blair believed it has a default form and was likely artificially created to spread an alien civilization around the universe. When they found the creature it had three red eyes and tendrils in its head and Dr Blair came to the conclusion that when it had finish assimilating all the life forms it would return to its default form, unless it needed adaptations to survive. 


Thirdly, the creature is telepathic and as it thawed out in the book, it would mess with the minds of the crew and it knew what they were all going to do. They couldn't hide anything from it.
