What is the largest animal on earth today? To properly answer that question you have to break it down into 2 different categories. The first being
land animals, and secondly, the sea dwellers. The largest land animal is the African Bush
The African Bush Elephant is the largest living terrestrial animal, normally reaching 6 to 7.3 metres (19.7 to 24.0 ft) in length and 3 to 3.5
metres (9.8 to 11.5 ft) in height at the shoulder, and weighing between 6,000 to 9,000 kg (13,000 to 20,000 lb).
On the other hand the largest sea animal is the Blue Whale
At up to 32.9 metres (108 ft) in length and 172 metric tons (190 short tons) or more in weight
Why is it that the largest sea animal today is nearly 10 times heavier then the largest land animal? Simple, the seas
supports much of the weight of the whale allowing the body to grow much larger.
With this in mind, why is it that the dinosaurs were able to grow to such massive sizes?
The largest dinosaurs are many times the size of an elephant. And dinosaur skeletons aren't as well-designed for bearing weight as elephant
skeletons. Dinosaurs are impossibly large for planet Earth, but their bones are proof that they must have existed
in order for the largest dinosaurs to function, gravity must have been at least 1/3 (and possibly as low as 1/4) what it is today
But how is it possible that the gravity of earth was only a fraction of what it is today? Well one theory coinscides with the
electric universe theory
The Electric Universe offers a different point of view. Gravity is not a constant. It's a variable that depends on the plasma environment. So
Earth in the Mesozoic Era may have had less gravity than it has today
Another theory is the expanding earth theory
The fossil record is full of animals that could not survive in today's gravity. Arthropods bigger than humans. 3-ft long dragonflies. 2M
millipedes. Giant claw reveals the largest ever arthropod" (2007). To say nothing of the dinosaurs -- 350lb flying creatures, enormous saurapods,
etc. No way in the world they could make it in today's world. Yet somehow, they used to. A smaller Earth would explain reduced gravity.
There are other theories that incorperate lowered gravity such as the hollow earth theory
and the Nibiru theory
, but no theory has been validated.
So is it possible that 65 million years ago the earth had substantially less gravity then it does today? Does the sheer magnitude of the dinosaurs
point to a lesser gravitational field?
A popular theory for the extinction of the dinosaurs is an asteroid impact. Could it be possible that the impact not only extinguished the dinosaurs,
but added a signifigant amount of mass to the earth as to dramatically increase the mass, and therefore increase the gravitational field?
What do you think ATS?
