T. rex could have been 70 per cent bigger
How It Works UK|Issue 194
There's no denying that Tyrannosaurus rex was one of the biggest dinosaurs to ever walk the planet. But how big could this dinosaur get? In a new investigation, researchers attempted to answer that. Palaeontologists from the Canadian Museum of Nature in Ottawa estimated that the largest T. rex may have tipped the scales at a whopping 15,000 kilograms, making it heavier than an average school bus, which weighs about 11,000 kilograms.

T. rex could have been 70 per cent bigger

Currently, the heftiest T. rex on record is a specimen nicknamed 'Scotty', which weighed 8,870 kilograms when it was alive, about as much as 6.5 Volkswagen Beetles. According to the new research, the largest T. rex "would have been about 70 per cent bigger" than Scotty, said Jordan Mallon, a research scientist and head of palaeobiology at the Canadian Museum of Nature. "That almost doubles the size of T. rex," Mallon adds.

The Space Force is launching lasers into orbit

The Space Force aims to better pinpoint the location of Earth's true centre using lasers on GPS satellites, slated to launch in 2025. A set of Laser Retroreflector Arrays, or LRAS, will be installed onto two GPS III satellites, SV9 and SV10, as part of NASA's Space Geodesy Program. The lasers are designed to make precise sub-centimetre measurements using a technique called Satellite Laser Ranging, which will allow researchers to more accurately determine Earth's centre.
