How mental is space.
40 years that voyager 1 has been traveling for at 35-40k miles an hour and its still not reached the end of space.
This just blows my mind the concept of eternal emptiness.
We are but grains of sand.
Anyone else into this or have an opinion or on anything else unexplained or wondrous in this universe (or the next). |

I read somewhere that it was only 66 years between the Wright brothers first flight and the Apollo 11 moon landings. You'd think, given that, we'd be much more established on the moon or on our way to Mars by now. |

I was fascinated and excited by Tabby's Star and the potential for a Dyson sphere around it... but then a bit let down when it seemed to be just gas clouds causing the fluctuations in luminescence. |

End of space? It's barely left our own solar system!
Our solar system is one very small part of a galaxy known as the Milky Way (thank the Greeks for the catchy name). In fact, our own sun is one of half a trillion known stars in the Milky Way.
The Milky Way is itself one of two trillion galaxies discovered so far...and they are all flying away from each other at incredible speed.
There are more stars in the known universe than there are grains of sand on the entire planet. That should put things into perspective.
HHGTTG was right...

Wonder how many undiscovered planets their is too.

I can never get my head around what the end of space even is, what happens when you get there, would it be like flying into a brick wall? What’s the end of space made of and if someone one day designed something to smash through the end of space what would be on the other side?
I’ve heard loads of people saying that the universe is expanding but if that’s the case what is it expanding into? There has to be something on the other side for it to expand into it.
Blows my mind. |

Our Sun is just a star like every other star you see at night, there’s absolutely hundreds of billions of billions of stars (don’t know exactly how many but it’s a lot) and they all have planets orbiting them like our Sun does. |

We are all just stars living on a star basically! Wonder if David Bowie is an actual Starman now? Lol |

Not every star is known to have planets orbiting it but it seems that many do. Even if it was just one in a hundred stars that have planets once you multiply that number by trillions (which is billions times billions) it is a really big number.
Drake's Equation is certainly interesting reading. However, distances in space are so huge that even if two planets with coexistant intelligent life detected each other every question and reply would be - at least - centuries apart.
A bit like Fab really... |

Are you saying a trillion is one billion times one billion or have I misunderstood you? |

It always blows my mind that if a ship like Voyager could travel at the speed of light which is 186,000 miles per second (yeah per second - not per hour) it would still take it 4.25 years to reach the nearest star after the Sun.
Compare that to the fact, like you say, Voyager is doing a 'sluggish' 35-40,000 miles per hour.
Just mind-blowing. |

It all depends on which definition of a billion you use to start with and, therefore, how many powers of ten are involved.
In America a billion is one thousand million (nine zeroes)
In Britain a billion is (err, was) one million million (two times one million). This is where the "bi-" (two) prefix comes from (twelve zeroes).
Everybody (annoyingly) uses American these days. So, a billion is a thousand million, a trillion is a thousand of those billions etc. - under this system a trillion has 12 zeroes.
In strict British a trillion should be a million million million (tri-) so 18 zeroes.
Americans just like making things look bigger than they really are. But space is still big. Really big. In fact, you really wouldn't believe just how big it really is... |

Diagonally Parked in a Parallel Universe |
Reading the link below blows my mind as it gives the scale of the universe if Earth was reduced to the size of a grain of sand.

Loads of youtube vids portraying how small Earth is and other planets size and distance etc.
Shocking to see we are just like a pinhead compared to other planets and solar systems.
I think time and space is infinate as it just keeps getting larger and larger.
