Thread by @MrAgScience1

Read @NeilDegrassi book “Astrophysics for People in a Hurry” as my knowledge on Earth and Space was limited.

So here’s a thread of fun facts that you can add to your PowerPoints.

All the energy that led to the Big Bang 14 billion years ago was contained in the volume of one trillionth the size of a full stop. “.”

As the cosmos expanded, the temperature dropped rapidly below a trillion degrees Kelvin

A light year is 10 trillion kilometres. That’s 58 million trips from Dublin to Sydney.

In the first billion years, almost 100 billion galaxies formed, each containing billions of stars which were about 10 times the mass of our Sun

Anaerobic bacteria was the first form of life that excreted oxygen and transformed earths carbon dioxide rich atmosphere

65 million years ago (2% of Earths past) a ten trillion tonne asteroid hit the Yucatan Peninsula obliterating 70% of Earths flora and fauna.

The further away we look in space, the further back in time we see. MINDBLOWING

The power and beauty of physical laws is that they apply everywhere whether you choose to believe in them.

Our nearest galaxies are 200,000 light years away

Supernovas are stars that have blown themselves up, which increases their luminosity a billion fold

Quasars are super luminous galaxy cores.

Hazard of space exploration, your blood cells would burst from lack of atmospheric pressure

85% of the universe is dark matter.

If the Earth spun 1.41 times faster our planet would achieve escape velocity and leave the solar system entirely.

Everything that is not the Sun, adds up to less than 0.2% (500 times)of the Suns mass.

The Sun is one of a 100 billion stars in the Milky Way. The Milky Way is one of a 100 billion galaxies in the universe. WE ARE A DOT.

Supernovas all have the same wattage, the bright ones are close and dim ones are further away.

Hydrogen is an explosive gas, oxygen supports combustion. The two combined forms a liquid that puts out fires 😂😂

Ah stop…. Every second 4.5 billion tons of hydrogen slam together to make helium within the 15 million degree core of the Sun

Helium increases the vibrational frequency of your windpipe or larynx which makes you sound like Mickey Mouse.

High pressure sodium street lights are white.
Low pressure sodium street lights are yellow.

Mars highest mountain Olympus Mons is 65000 feet compared to Everest at 29000 feet.

Earth is flattened at the poles by about 26 miles.

Mass of galaxy - Mass of planets = Dark matter

Light spectrum
Radio waves, microwaves, infrared, ROYGBIV, ultraviolet, X rays and Gamma rays.

Earth rotates fully every 23 hours 56 minutes

The largest telescope was completed in 2016 called the Five hundred meter Aperture Sphercical radio Telescope (FAST). Larger than the area of 30 football fields.

Earth has orbited the Sun 4.6 billion times.

Most asteroids will hit Earth in the next 100 million years. One larger than a kilometre will have enough energy to destabilise the Earth ecosystem and put Earths land species at risk of extinction.

Our moon is 1/400th the diameter of the Sun and is also 1/400th as far from us, making the Sun and the Moon the same size in the sky.

Io, Jupiters closest moon is the most volcanically active place in the solar system.

The Sun loses a million tons of material from its surface every second.

Estimated that there are 40 billion Earth like planets in the Milky Way

The going one in our three pound brain has allowed us figure out our place in the universe

There are more bacteria in 1cm of your colon than the number of people who have EVER existed

Imagine there could be a brainpower is to ours as ours is to chimpanzees

A single breathe draws in more molecules of air, than there are breathfuls of air in the Earths atmosphere.

Lastly…….

There are more stars in the universe than grains of sand on any beach.

There are more stars in the universe than seconds have passed since Earth formed.
