Additonal facts: if the distance between Proxima Centauri and the Sun on on this scale was 202 km, and in reality it's 4,2 ly away, it means that 1ly =42 km on the scale. This means that Andromeda galaxy, which our Milky Way is about to merge with in 5 Billion years forming Milkdromeda, on this scale is 120 Million kilometers from the pea Sun (roughly 80% of the distance to the real Sun). Our galaxy cluster (Local Group) is about the size of a solar system in this scale. And the diamater of the observable universe (92 Billion ly) is 4,5 Trillion kilometers in this scale which is 0,5 ly.

How is it possible, from our perspective, that this occurs, if all stars are at different distances from earth (some thousands of time farther away from each other) and yet they all appear to move from our perspective at the exact same speed, all in THE EXACT SAME DIRECTION??

I mad this gfycat.com/HorribleAllGermanshepherd little anymation recently were I pretended that electrons are spheres (which they aren't) to compare its weight to that of a proton and I also made this imgur.com/a/0TFn0 periodic table, where each element sticks out proportionally to its calculated radius.

Gareth Dean The trouble is at school you learn the solar system type model of atoms which is easy to visualise but wrong.

Then you go even deeper and realise protons and neutrons behave the same but are made up of quarks and the picture gets harder and harder to imagine!

One of the unforgettable moments that lead to me getting a physics degree was when an older boy ( I was around 7, he around 15), while walking me home at night, asked me if I knew how far were the stars? This was the 50s and so space travel had hardly begun, let alone general awareness of matters astronomical. I told him I did not know, and, although I forget his exact words, he was able to convey to me the staggering truth of it all. We walked the rest of the way home in silence because I was literally shocked and lost for words.

When you start considering that in just 117 years, we've gone from a wooden & canvas plane that flew at 56 km/h, to space probes reaching speeds of hundreds of thousands of km/h with the aid of gravity, we're a whole lot closer to interstellar travel than people think.

It feels insanely slow to you because we have an peculiar relationship with time. For us, 100 years is enormous, it is our entire existence. But really 100 years is nothing for the universe. It wouldn't matter much if the speed of light would be a billion times faster or slower, sure it would take a billions times more or less time for light to travel distances, but in the end it would still be nothing compared to infinity.

[@Locut0s]

That is a good point you make Flyfeuhhh. Velocity after all is simply defined as change in distance / change in time. So two way to express what I said above about how slow the speed of light is, is to simply recast that as the speed of light is fast but the universe is so INSANELY large (obviously). Or it's only slow for beings like us that have such insanely short life spans.

We are not that small. In fact, we are way closer to the size of the observable universe than to the size of a planck length (smallest distance in physics). Also, the observable universe is far too small mathematically speaking. For instance, If you fold a paper 103 times, the thickness of the paper is already larger than the observable Universe, which is 10^26 meters in diameter. 10^26 is a very small number in Mathematics. For instance, Googol is 10^100, Googolplex is 10^10^100, yet both are still very small numbers in Math.

You can look at real objects like the ones Cody talked about in this video, or you can view the trillions of other objects that DON"T exist. SpaceEngine generates realistic planets via procedural generation. You can view atmospheric, physical, and orbital detail about every little detail of an object..

The volume of the observable universe is ~3.6x10^80 Cubic Meters. A human takes up ~0.1 m^3. Or rather, you take up 1/3600000000000000307409205720723958754374371817423089397567280740026905028139679744th, or 0.00000000000000000000000000000000000000000000000000000000000000000000000000000000028% of the universe, at least for the moment. The volume of the observable universe is expanding at the speed of light, so that number is shrinking at a cubic rate.

Frank22 Frank22 Frank22 Well, in order to give you a better feel: In my opinion the dream of being part of a race that could have the capability to handle such a huge task is overwighting the fact that we are so "small ".

It's incredible that pluto is so far away from the sun yet still under the influence of it's gravitation Cool video!

Beautiful reference to Hitchhiker's Guide to the Galaxy. I am so glad to see the Douglas Adams is still being read buy those of us that just love Ford Prefect and his adventures.

Thank you for the chill and easy to understand presentation. No goofy music getting in the way of your explanations. Great teaching. Thank you!

[@JesseDiebolt]

This is just incomprehensible. I just can’t get over the scale.

[@SidusBrist]

I love how speed of light in scale would be like a snail or a caterpillar moving very slowly.

[@Mnimosa]

Good observation. A snail is a bit too slow, at 1m/h (metre per hour). Assuming it never stops, it would go a bit under 40 kms in 4.3 years, so about 20% the speed of light. A caterpillar at this scale would travel at around 7 times the speed of light.

[@JustinLodes]

What boggles my mind even more is how photons have no clock. As soon as they are emitted they instantly get absorbed at their destination no matter how far that destination is. It could be billions of light years away

[@towerofresonance4877]

​@John J. Rambo This is where multi universes come to play. A thing that exists even beyong a photon is the very waves we create in thought. There is no barrier. Humans instinctively hide behind a rock, but even the densest Earth material cannot escape permeation.

[@PacoFTW]

This makes me feel such existential dread. We’re so small. No wonder we haven’t met aliens.

We need warp drive technology. So get to work. I expect it within the next 5,000 years.

We may be small but we are still the universe’s way of acknowledging its existence.

It's not that there aren't any aliens, it's just that there is so much space that thousands of interstellar empires could occupy the same space and never notice each other.

@@SherwinGooch Not quite, the amazing thing about Carl Sagan wasn't just his knowledge, it was his enthusiasm, the way he spoke, the way he could simplify stuff, so that almost everyone would understand the subject in question.

This why when people try to talk to me about alien visitors I roll my eyes. Until someone can explain using Physics how any being can cover that distance and not miss the Earth entirely I'll continue to believe we are essentially alone.
