I'm really interested in astrophysics so here's a thread to show you how BIG our UINVERSE actually is:
(pls don't let this flop)

Intro: This is our planet, the Earth.
It might seem huge, but compared to other planets and the rest of our galaxy/universe it's actually super super small.

some might think that the moon is very close to our planet because it often looks so big in the nightsky, but it's actually pretty far away.
Around 384,000 km / 239,000 miles!
this is also the furthest away any human being has ever been away from Earth.

let's go a little further:
this is a photo taken on Mars and the tiny dot u see there is our planet!
Mars is on average 225 MILLION Km away! That number can vary depending on the current location of the planet.
Sending a message from Mars back to Earth would take around 20 mins!

This is the Voyager 1 Space Probe. It is the furthest away man-made object from Earth.
It's 138x further away from us than the sun is! To put that in perspective, the sun is approximately 150 MILLION Km away! (for Americans: 1km=0.62 miles)

Here you can see a picture taken by the Voyager 1 Space Probe. Every person that ever existed lived/lives on that tiny dot in the middle of nowhere.

Voyager 1 is traveling at an incredible speed of 17km per second (11mi/s), but even with that speed it won't be able to break out of the reach of our solar system for another 30,000 years!!

This is our interstellar "neighborhood".
The star "Proxima Centauri" is the closest other star to us other than our sun. But it's still more than 40 TRILLION Km away! If Voyager 1 traveled in the right direction, it would still take it over 70,000 years to get there!

This is our entire Milky Way Galaxy and you can see where our planet is located. The tiny yellow dot is the furthest extent of human radio signals meaning that any possible Aliens living outside of that range are totally unaware that we even exist.

Our galaxy spans over 100,000 light years from end to end!
(1light year= ca. 9.461 TRILLION km!)
There are more than 100 BILLION stars and planets in our galaxy!
But 99% of the stars you can see with the naked eye are limited to that small yellow region there!

Zooming out further and we arrive at the local group of galaxies. It's a collection of 54 different galaxies that is about 10 MILLION light years across!

Zooming out even further and we arrive at the "Virgo Supercluster". In there are at least 100 other groups of galaxies just like our own there.
The distance from one side to the other is approximately 110 MILLION light years!

But even that is just a tiny part of the massive "Laniakea Supercluster". It contains at least 100,000 galaxies!
The distance from on side to the other is around 520 Million light years!
(again: 1 light year= 9.461 TRILLION Km)

But even that is just a very tiny part of the entire observable universe!
It is home to at least 2 TRILLION different galaxies, which together contain more stars than there are grains of sand on our entire planet!
The distance from Earth to any side is 46.5 BILLION light years!!

What might be even more interesting, is that we don't know what lies beyond the observable universe. There could be so much more that we don't know of.
It's hard for us to imagine those massive distances.

The thing is that the light from some parts of the universe hasn't had enough time in the entire universe history to reach us yet because it's so far away.
Some may even never reach us because some parts of the universe expand faster than the speed of light!

According to the theory of Cosmic Inflation by Alan Guth it is possible that the entire universe is 150 SEXTILLIONx bigger than the observable universe!!
That number looks like this: 150,000,000,000,000,000,000,000!

All we know is that we're just an incredibly tiny part of the entire universe and we have no idea how big it actually is or what else is out there.
Considering the huge amount of different galaxies, it's also very likely that there is other life somewhere out there.

That's it for now, I hope you enjoyed it.
Thanks for reading
I just think this stuff is super interesting
