Solar System dynamics discussion thread

20956 Probably I could solve this by make the time step variable and longer at larger distances, but I'd need to sit down and think about the best way to implement that Don't worry Watsisname you made such a great work with all your explanation. No need to see the actual orbit. I was just curious a...

Solar System dynamics discussion thread

Some compliments I would like to quote each paragraph and say things like "Awesome!", "amazing", "wow, never thought of that" and "very well explained" but since that would just be hard to read and redundant I'm just going to throw a global "SPECTACULAR&...

Qr Bbpost I am currently writing up some explanation for the last one (precession of Mercury's perihelion)

That is going to be an awesome inaugural post :)
I'm also going to take notes.

How do you think we can get to Proxima b?

20904 It says right here, "atomic particle erosion" in the "protective coating" Wikipedia is not wrong. Maybe it's easy to misinterpret that. When they say atomic particle erosion they are not talking about atoms or subatomic particles been eroded, they are refering to the erosi...

How do you think we can get to Proxima b?

20896 which means electrons get eroded by the things in space I know we said this several times now but I want to emphasize this. If atomic erosion is a strange use of the term "erosion" then electron erosion is just totally wrong. Electrons are elementary particles, they do not erode. If...

How do you think we can get to Proxima b?

20874 I just double checked and it's atomic PARTICLE erosion so that means that the electrons are what get eroded. Exactly. In the case of starshot you are dealing with so called sputtering. Cosmic rays and stellar wind particles moving through interstellar space can indeed erode the surface of tho...

I'll keep working on it and taking your info into account!

Awesome!! Keep the ideas coming. Good way of handling our skepticism :)

How do you think we can get to Proxima b?

Doesn't clarify this to me either. And I'm gratefull that I'm not so confused about the actual physics here as I read Watsisname's responses. In fact there are important points still to be adressed. I suspect the amount of energy you need for the gamma ray laser is way beyond any other energetic out...

Science and Astronomy Questions

20783 Has the planet Tyche been verified? Has it been unverified? Or are we still not sure. The hypothesis of the existence of Tyche was never a very rigorous one in scientific terms. No data provided so far points to its existence at all. And currently, since 2014, it's a rejected statement inside...

How do you think we can get to Proxima b?

1) Why Mercury? 2) Why gamma rays? 3) Why a disk? 4) Also, having speed that surpass the escape velocity of the solar system does not mean you are accelerating at all. 5) I didn't understand what you mean with the hydrogen atom that strucks the disk and makes the device boost forward at all. Why? 6)...

Science and Astronomy Questions

20749 Do astrophysical jets follow the rotation axis or the magnetic axis? The jets follow the magnetic axis. Since the magnetic axis can be missaligned with the rotation axis the jets are constantly sweeping around. The pulses you see in a pulsar are the beams passing in the direction of Earth, li...

20717 What would it take to view a natural Arago/Fresnel/Poisson spot from a celestial body?  Perhaps it happens in wide binary systems containing a cool neutron star (although the cooling time of a neutron star might be an issue).  Neutron stars have a radius of about 10km and, using the maximum t...

20702 And I was also very curious to see what it would look like from inside the spot. Just spectacular. Really impressive. It resembles Baily's beads in a solar eclipse (just that is a completely different phenomenon). The experimental setup was done by trial and error or you started with some cal...

The first time I heard of it at university I was staggered. Is such a mental break for our intuition...
If you were at the Arago spot looking at the coin you would see light of the source behind it even if that coin is blocking straight light rays. Its just incredible.
