Time Travel

Dr. Ronald Mallet is a Physicist who is a professor at the University of Connecticut. He has invented a set of equations that allows him to build a time machine. This machine uses Einstiens Theory of relativity which allows you to manipulate space an time. Mallet proposes to use light to manipulate and twist time. He only proposes to send back sub-atomic particles of information. But if it works it would be possible in the future to send back humans.
But this doesn't mean that we would be able to go back to see the pyramids being built. You could only go back to the point were the time machine was turned on.

Which is exciting because if he builds it and it works! He could receive information as soon as he turns it on from a future self.

Giant Tortoise

Life Span
One of the main reasons i love giant tortoises is because they live for the longest.

The oldest Giant Tortoise was believed to be Tu'i Malila who died at the age of 188 and just behind that Harriet who died at the age of 167.


But Adwaita was the oldest Giant Tortoise. He was a pet of Robert Clive who was a British Soldier who was credited for securing India in the 18th century.

There was a dispute regarding the age of Adwaita. However, now Adwaita's shell has beencarbon dated, determining his age to be around 255. This makes Adwaita one of the oldest creatures of modern times, beating Harriet by 80 years, and Tu'i Malila by 67 years.

Adwaita means 'one and only'

------------------------

Giant Tortoises can reach a huge sizes, t
hey can weigh as much as 300 kg (660 lbs) and can grow to be 1.3 m (4 ft) long.

The biggest population of Giant Tortoise today is in the Seychelles. Where there is approx. 152,000. Which is good news!

Madagascar, the Seychelles, Mauritius, Réunion, the Galápagos Islands, Sulawesi, Timor, Flores and Java are the islands where Giant Tortoises live / lived.

Giant Tortoise

Although the first giant tortoise was discovered in 1535, the species was not scientifically catalogued until the early 19th century; no one actually managed to bring even a sample of the tortoise back to England because they found it so delicious. Most early accounts describe only the taste of the tortoises.

Jupiter

Jupiters Rings
Jupiter's main ring system is formed by dust kicked up as interplanetary meteoroids smash into the giant planet's four small inner moons Almathea, Thebe, Adrastea and Metis. The ring system begins about 92,000 kilometers (55,000 miles) from Jupiter's center and extends to about 250,000 kilometers (150,000 miles) from the planet. NASA's Voyager 2 detected an uneven dust ring around Jupiter in 1979. One Voyager image seemed to indicate a third, faint outer ring. The Galileo spacecraft found a flattened main ring and an inner, cloud-like ring, called the halo, both composed of small, dark particles, and a third ring known as the Gossamer Ring. The third ring is actually two very thin rings made up of debris from Amalthea and Thebe. Unlike Saturn's rings, there are no signs of ice in Jupiter's rings.

Jupiter

Most people take Jupiter for granted. Jupiter could be the reason that we are here. The reason why there is life on Earth at all!

Because Jupiter is so big it has a huge gravitational pull. This means that Jupiter acts as our solar systems sort of 'vacuum cleaner'. It pulls all the debris that space throws around including big asteroids. Asteroids that potentially could be disastrous for Earths inhabitants. Because Jupiter has done this for millions of years it has prevented comets and asteroids from ruining our evolution.

So THANK YOU JUPITER

Time Travel

Time travel in reality is a mind boggling idea and seems utterly impossible.

Einstein's theory of relativity allows time travel in extreme circumstances. Some interpretations of quantum mechanics permit particles to travel backwards in time.

The speed of light is 67,000,000 miles an hour- nothing can go faster than the speed of light.

Time flows at different rates depending how fast you are going. So this means that if it were possible to travel very very fast lets say in a space ship. You could spend a year traveling extremely fast and come back to earth where a 100 years have passed on Earth. So you would age far slower than your friends back home.

Jupiter

I have always been fascinated by the Giant Red Spot on Jupiter about 5 years a discovered an amazing picture in the National Geographic magazine of the Giant Red Spot and i decided to paint it.

Time Travel

A 'possible' way to travel back in time is by traveling around a black hole. Black holes drag space and time around with it. So if you could travel towards the region where time is being dragged and travel around it then come back out of the region you could actually return before you came in. madness! But to do this would be extremely hard. You would first need to find a black hole and then also have a vessel of some sort that would be powerful enough to out run the pull of the black hole which is so powerful it could pull in a star.....a long shot, but possible.
