Well, the orbits are pretty circular—especially for the inner planets. But besides that this picture isn't meant to be very accurate anyway. Especially if I would take the relative distances between the planets into account, I would have a huge picture with huge gaps in between the outermost planets.
The reason I don't care too much about getting the orbits right is because that's not the purpose of these series. I thought I would let it speak for itself, but perhaps I should explain the purpose in the description. What I'm actually trying to do is keep zooming out from our solar system until you can't zoom out any further. Now, early on in the series things look very familiar, but towards the end things will get more philosophical than astronomical. It's a visual exploration in cosmology and I hope that these series will give people a better picture of the size and structure of the universe.
oh I see, carry on then, I'll keep tracking this, but I've seen those Hubble shots so, though one can't imagine how big the universe is, it's rather easy to see how small we are.
Yes I realize that, but that's one of the reasons for starting these series. It's an experiment for myself as well, but I feel like most images show the vastness of space but doesn't really show what the universe is. Most documentaries are too simplistic to me and focus on interactions between smaller regions of space (for example, the dynamics of our own solar system and the way it distributes comets from the Kuiper belt to the Earth region) or hugely focus on the center of the universe and how it started. They tend to look inwards instead of outwards, though with good reasons. There's a huge part of our universe we will never be able to see, and so looking outwards won't solve much. I feel like we've only just started looking outwards due to the finding of dark energy and the gaps seen in the microwave background radiation.
Last time I caught a documentary about space I learned that the space expansion is actually accelerating, since I had been told otherwise in highschool I found this über-exciting, then they said this information was available since the late 80's and that the school manuals simply weren't updated since -.-' As for dark matter, dark energy and background microwave radiation, I don't know a thing about that, I'll be fixing this is a near future.
Actually, the expansion of space was first theorized in 1922 by Friedman (Einstein initially added the cosmological constant to his theory of relativity because he thought the universe would both contract and expand, like it breathes) and observed by Hubble in 1929. Einstein then abandoned his concept of the stationary universe as the redshift Hubble saw in galaxies indicated they were moving away.
So, the fact that the universe is expanding has been known for a long time. It wasn't until 1998 however that it was discovered that the expansion is actually accelerating. The team (Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess) got a Nobel Prize in Physics for their discovery this year.
