I’m having hard time getting my head around the fact that there is no end to space. Is there really no end to space at all? How do we know?

The thing we might want to consider is if it matters in any material way. I CAN say with 100% certainty that is is so vast that whether it is endless or has an end is irrelevant to anything we currently know.
Unless we’re missing the MOST IMPORTANT feature or physical law of the universe no object (with mass) can traverse interstellar distances in less than millions or billions of millennia .
Our Solar system will cease to exist long before you could even collect current data from a distant destination.
It’s pretty big. Just considering our average Milky Way galaxy. For perspective, if you shrunk the Milky Way down to the size of the USA, our solar system would be roughly tue size of your thumbnail. The earth would be maybe the size of a red blood cell.
