Scientists estimate that the total number of ants on Earth is around **20 quadrillion** (20,000,000,000,000,000). 

There are approximately 3 trillion trees globally, based on a 2015 study. This estimate covers different tree species found across various ecosystems, such as rainforests, temperate forests, and boreal zones. Humans cut down around 15 billion trees annually, reducing the total count. Reforestation efforts aim to offset some of this loss.

There are an estimated 600 billion LEGO bricks produced since the company was founded. With approximately 100 million LEGO sets sold annually, it's estimated that there are around 80 LEGO bricks for every person on Earth. LEGO continues to produce over 36 billion bricks each year!

Estimating the number of stars in the universe is a challenge, but current scientific estimates suggest there are about 100 billion galaxies in the observable universe. Each galaxy contains roughly 100 billion stars. Multiplying these numbers gives a rough estimate of 10^22 stars, or 100 sextillion stars. This vast number illustrates the immense scale of the universe. However, this is just an estimate based on observable data, and the actual number could be much larger when considering the entire universe, including regions beyond our current observational reach. The universe is incredibly vast and still largely unexplored.

Imagine a beach so vast that it holds 7.5 quintillion grains of sand—7,500,000,000,000,000,000 grains, to be precise. To put this into perspective, if you were to count each grain at one per second, it would take over 237,000 years to count them all! This staggering number highlights the sheer abundance and minuteness of each grain, showcasing the incredible scale of nature’s smallest building blocks. Each grain, though seemingly insignificant on its own, collectively contributes to the vast, ever-changing landscape of our planet’s shores.

Estimating the total number of transistors in the world involves considering the vast number of electronic devices in use. As of 2024, it's estimated that there are about 2.6 trillion transistors in a modern smartphone, and billions of smartphones are in use globally. Additionally, there are countless other devices like computers, servers, and appliances, each containing millions to billions of transistors. 

Taking into account the exponential growth of technology and the sheer number of devices, a rough estimate suggests that the total number of transistors worldwide could be in the range of hundreds of quintillions (10^20). For example, a rough figure might be around 100 quintillion transistors (100,000,000,000,000,000,000).
