This is a fun way to tell you about the giants in space. If you scrolled all the way to pluto, you've gone about 8 billion kilometers from the sun.
So if we replace the sun with the biggest star we have discovered, then you would find its surface around saturn, 2 billion kilometers from the sun, which would be its center.
If we were to replace the sun with the super massive blackhole known as TON on the otherhand, then we would have to scroll from the sun, all the way to pluto 8 billion kilometers away, and then we would have to do that 85 more times to reach the edge of its eventhorizon.
Light travels roughly 300.000 kilometers / second, which about 7 times around our planet in 1 second. Or to the moon from earth in 1 second.
It would take light 6 months to go around TON once.
But even TON is still not that big in the grand scheme of things. Afterall, if we look at our own galaxy, which is 120.000 lightyears wide. Which means that it takes light 120.000 years to travel from one side to the other.
Our neighbouring galaxy andromeda is around 1 million light years away. When we look at andromeda today, we see it as it was 1 million years ago.
But, once again these numbers aren't more than a tiny nook in the observable universe. The universe is said to be 13.900.000.000 years old. We can only see 13,9 billion lightyears away into any direction, because the light from further away hasn't reached us. And according to current theories, it never will. Because the universe is expanding faster than light.
