  • It gets messed up really fast tho … so if you travelled at the speed of light 2 million light years to Andromeda and it only felt like a few minutes to you … then you travelled back 2 million light years back to our galaxy and it only felt like a few minutes to you … wouldn’t 4 million years have passed at your start point while you were gone?


  • Same here … I had those moments of awareness several times when I was a kid learning about all this stuff in school. Together with my background as an Indigenous Canadian (I’m full blooded Ojibway and it’s my first language before English) I was always taught by my elders to stay aware of my place in the universe and existence.

    We lived in remote northern Ontario away from cities and towns and the sky was always a deep dark expanse, especially on a moonless night. One of the greatest spectacles I ever witnessed was heading out on the winter ice road near Moosonee on James Bay. My friends and I drove out for fun several miles north for fun. It was February and it was a frigid minus 40, no wind, no clouds, the air perfectly still. We stopped at a bit of a rise in the frozen mushkeg where there were no trees. The sky was so dry, so clear and so unobstructed by anything in the air that we could see every star down to the horizon. At that moment, for an instant realized I wasn’t looking up … I was looking at the universe from the edge of a sphere … it was almost dizzying because if I thought about it too long, I felt as if I were on the edge of a cliff ready to fall off.


  • I always loved those examples that show the scale of planets, stars and systems. I remember years ago before I got on the internet (yes I’m that old), reading a comic or book, I can’t remember where … all I remember is the cartoon and illustration.

    If you made a scale model of the galaxy and fit it in between the earth and the moon … our sun would be the size of a marble and it’s nearest neighbour would be about a mile away. And some of the largest stars would be about the size of an average office building.


  • I don’t fully understand how the science and theory works around all that … all I understand is that it is so unbelievably far away that in order to cross any of those distances or even think about crossing those distances, it begins to break our normal understanding of speed, distances and time.

    Here’s another perspective … this is our local galactic group. Our nearest galactic neighbor is the Andromeda Galaxy … it’s located about 2 million light years from us. Again, if you could travel at the speed of light (which is impossible), it would still take you 2 million years to get there.

    Another way of thinking of it is that the light we see from Andromeda today started it’s journey when our first prehistoric human ancestors first evolved in Africa 2 million years ago.

    So the light we see from Andromeda today started it’s journey when our ancient African ancestors looked like Homo Hablis - estimated to have been around in Africa 2.4 million years ago and looked like this
