But as governments whant to keep ignorant the people they accept the thousand or a million as a billion but the difference is huge like this. 1.000.000.000.000 a billion and 1.000.000.000 a thousand of a million. there is a gigantic difference. A trillion is 1.000.000.000.000.000.000 every million of a million level adds 6 ceros. Don't get ...
Tim - the best example I could find was there was a guy called Jeremy Harper who, in 2007, decided to count to 1 million for charity. And he streamed himself 24 hours a day so you could just look in at what he was doing at any given moment and he counted for about 16 hours every single day, and it took him a total of 89 days to finish. So, if ...
While you were reeling from that one, Michael please show us your working. Michael - Let’s start with the stars in the visible universe: crudely speaking there are about 100 billion stars in a galaxy like the Milky Way, and about 100 billion galaxies in the universe. So if we multiply these numbers together we get the total number of stars in ...
The fossil record of bacterial cells goes back about 3,500 million years, that's 3.5 billion years. And so far as we can tell, these cells were very similar to their modern equivalents. Hannah - So, different forms of life may have started, but it seems that just our form of life survived over the last 3.5 billion years.
Maud - Yeah. In between 3.7 and 30 trillion. Stuart - I’m going to go for a bit less than a gram. Round it to one - physicist approach. Chris - Maud, put us out of misery then. Maud - We can more or less do an approximation of under one nanogram.
ASTEROID_EARTH. The Cretaceous-Palaeogene (K-Pg) Mass Extinction, 65.5 million years ago, is probably the most famous biotic crisis, because it’s when the dinosaurs died. But, often forgotten are the other 40-76% of species that became extinct at this time. Despite extensive research, the cause of this mass extinction event remains contentious...
They burn so hot, they burn through their fuel much, much more quickly than smaller stars. So a star like the sun, which is pretty small, would last about 10 billion years. That's about 10,000 million years, more or less. A massive star might last 10 million years, which sounds like a long time. It's sort of a blink of an eye compared to the sun.
Each lightning flash is about 3 miles long but only about a centimetre wide. It discharges about 1-10 billion joules of energy and produces a current of some 30,000 - 50,000 amps, which heats the surrounding air to over 20,000 degrees Celsius, three times hotter than the surface of the sun (6000 degrees Celsius).
If you go back in history, the population of Earth was pretty tiny compared to today. There are over 7 billion people alive right now, but at the height of the Roman Empire in around 1 AD, there were only 300 million people on Earth in total. So there is, perhaps, some logic to this myth even if it is very wrong.
Denise - So for one single major fishery a year around 740,000 kilometers of fishing line alone is lost. And with that, our 14 billion hooks. If you wanna put that in perspective, that's about circling the earth more than 18 times for that fishing line or going from earth to the moon and back. We also estimate around 3000 square kilometers of ...
