    Galaxies are massive beyond our understanding. If Andromeda were brighter, it'd appear 6 times larger than the moon despite being 2.5 million light years away. The Milky Way is 105,000 light years wide... to send a radio signal from one side to another would take longer than our species has existed. It's really mind blowing and humbling.

    Good Video - but to add a little bit critizism ... it doesn't show the newest research on HOW our Galaxy really looks like. The Milkyway doesn't seem to be a common Spiral Galaxy - it's Spiral Arms are warped, on side points a bit more "up" and the other side a bit more "down". And it has some other oddities which most other Galaxies don't have (e.g. Ripples in it's arms). I mention this because i love our Milkyway, and it shows that we are living in a really unique place in the Universe.

    Some people do not even know what a galaxy is let alone what our galaxy looks like from the outside. I remember years ago when I mentioned galaxies to my late father he asked me what a galaxy is. Nor did he know that a lunar eclipse can only happen at full moon. My sister didn't realize that the moon is often visible in the daytime. Acquaintances of mine often (mis)use the term "astrology" to mean astronomy. The general public is sadly uninformed on astronomical issues.

    Paul,
    At about 1:43 you said, “Firstly, we can see a fairly narrow band of bright hazy starts that circle the sky-the thing we call ‘the Milky Way.’ Which indicates that we are in a flattened disk of stars and not in a sphere. Because if that were the case, we would see many more stars equally distributed in every direction.”
    I too agree with this principle that homogeneity would indicate we’re at the center. Interestingly, the other galaxies--outside of our own--we see are evenly distributed from our earthly perspective. Would you agree that this data-along with the homogenous distribution of cosmic background radiation---indicates the Milky Way galaxy is at or near the center of the Universe?
    Thank you in advance.

    voyager 1 is roughly a light day away ...3rd june in 2022. would be around 21.2 hours of light distance ( according to wiki)
    so roughly a lightday 50 years after its start
    makes 50x365 = 18250 years more for a distance of one light year ....if the speed does not change
    or to alpha centauri , the nearest star ( 4.2 light years ) 76650 years ......without braking ;-)
    or f**ing long time /distance
