The most mind-boggling explosion you can imagine doesn't come close to what the universe can create. When stars 150 times the size of our sun explode, they produce the brightest light sources in the universe and release as much energy in a few seconds as our Sun will produce over its entire lifetime of 10 billion years. That's about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe. What's more, these GRBs could be killing our chances of ever discovering life on other planets. Hopeful scientists say that we are not alone in the universe, but if that is true, then where the heck is everyone? One explanation could be that life in the universe is truly rare because GRBs are sterilizing the cosmos. On Earth, gamma radiation is generated from radioactive decay of elements and is extremely hazardous to living beings. These super-intense beams of gamma radiation — the gamma-ray bursts — are created by the most powerful type of stellar explosion: a hypernova. If your home planet is in the way, say hello to a mass, if not complete, extinction. Events like these could, however, be sterilizing the universe. If other planets are anything like Earth, then it will take billions of years of evolution to reach the point at which life on other planets is intelligent and technically advanced enough to build spaceships that can escape their solar system and explore other worlds. If a GRB occurs at any point during that society's evolution, the chances of intelligent life on other planets is much lower than we think. This issue is known as the Fermi paradox. Because they are so bright, we can observe GRBs at incredibly far distances at all corners of the universe. We detect on average one GRB every day, which means that a single galaxy should see one burst every 100,000 to one million years, which is rare even by cosmic standards. Our home galaxy, the Milky Way, has never experienced a GRB, as far as we know. The most likely candidate for a GRB in our galaxy is about 7,500 light years away — a safe distance from Earth but close enough to potentially be bright enough that night will seem like day.

What is the capture recapture method?

Capture recapture is a sampling technique used to estimate population size. To do this we need to set up a controlled investigation where the objects (usually animal populations) are captured, marked, released, and then recaptured after a period of time.

thirdspacelearning.com - Capture Recapture - GCSE Maths - Steps, Examples & Worksheet

Calculating the total population using capture recapture

To work out an estimate for the total population we use the formula:

frac{M}{N}=frac{R}{T}

where:

M = Total marked

N = Total population

R = Number of marked recaptured

T = Total recaptured on second visit

This can be rearranged using basic algebraic principles to obtain the formula:

N=frac{MT}{R}

E.g.

A farmer wants to calculate the number of mice in a barn.

One day he places a trap for mice to enter. 12 mice are counted, marked, and released. 5 days later, he places the same trap down for mice to enter. This time he counts 14 mice, 7 of which have been marked from the previous capture. The mice were then released.

Estimate the total size of the mouse population.

Here we are estimating the value of N (the total population):

M = 12 (the total marked on the first capture)

R = 7 (the total marked on the second capture)

T = 14 (the total captured on the second capture)

So we now have:

N=frac{12 imes{14}}{7}=24

The estimate for the population of mice in the barn is 24 . This is because 7 out of the 14 mice in the recapture were already marked, which is 50% of the sample and so if 12 mice represented 50% of the population, 100% would be twice this amount, which is 24 .
