2017年2月7日 · a billion is a million of a million like this 1.000.000.000.000. 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

2023年12月22日 · To get to the bottom of your Christmas conundrum, James Tytko called on mathematician Ems Lord to crunch the numbers... Ems - Thanks James. What a fun question. After a bit of Googling, I’m going to assume that each reindeer can tug a hefty 136 kilograms. And there are approximately 2.4 billion kids under 18 eagerly awaiting their presents.

2024年12月6日 · Matt - With telescopes like the James Webb Telescope, we can look back around 13 and a half billion years into the past to the first few hundred million years after the Big Bang, and we see baby galaxies. These baby galaxies, through billions of years of cosmic history, grow and make stars and eventually become the galaxies we see around us today.

2024年9月3日 · Now when you look at many gold mines around the world, the average globally is around about one gram per tonne. So if you don't have to pay the costs of actually digging the rock out of the ground and all you have to do is basically get it from the tailings dam or that mountain of residue into a process plan, you've basically had to pay half ...

2023年1月10日 · It's almost counterintuitive, right? You would think ‘big star, more fuel, it would last longer’. But big stars really do sort of live fast and die young. 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.

2018年8月21日 · 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 universe which comes out as 1 with 22 zeros after it, which is ...

2024年8月6日 · The numbers came as about 50 and maybe 90, which corresponds if you just run the universe in reverse with that number to an age of the universe between 15 billion years or 10 billion years. And we were pretty sure at the time that …

2025年1月28日 · Charlie – Exactly. My colleague James DeGregory at the University of Colorado estimates that a 60-year-old person will have 100 billion cells with mutations commonly associated with cancer. Yet, our lifetime risk of cancer is between one in two and one in three. To give you context, the human body has roughly 30 trillion cells.

2007年6月3日 · 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).

2012年12月7日 · Then, 3 billion years later, an explosion of complex life, and we start to see the beginnings of animal groups we see across the globe today. Jumping to the Mesozoic, we see some of the largest creatures ever to live in the oceans, and then see almost all of them wiped out along with the dinosaurs.
