Thanks for showing me that. I will find some other forums more appropriate.

Oh. Where do people speculate about physics because I'm not skating, I swimming?

Yes. I read that they discovered that Oumuamua was accelerating away from the solar system. Do they know that the solar system is not accelerating? I don't offer any explanation for why the solar system could be accelerating but by your incredulous reaction to the proposition that some part or...

How so we know the solar system is not traveling? I think that is what you giving in your reasoning.

I think that only the star would need to be moving from some current or earlier force, such as an early event like the big bang. It doesn't have to be that though. I would think if the star is traveling then due to its gravitational force, the other bodies in the system would travel with. That...

If we pretended it was an asteroid without any gassing could the unexpected, perceived acceleration of Oumuamua have been instead, attributed to an accelerating solar system? I think the rate of acceleration would have to be relative to Oumuamua. I was hoping in this exercise, it might be...

If Oumuamua was a normal asteroid passing through an accelerating solar system, how fast are we accelerating and could the origin be traced if this were the case? Edit: Also, if it were to be assumed we simply overtook Oumuamua, can we determine our flight path?

Maybe it's intergalactic. Who knows. Sounds like they did the best they could. Perhaps whatever was out there is gone now. If it was that long ago. Davide Farnocchia sent me this link. Karen Meech and Davide are very kind (to over enthusiastic newbs, in this case. Maybe I should rather say...

Ok. Maybe someone else can come up with an equation. I will check tommorrow.

I understand these terms describe different things.

Not talking about photons. Just a rock. Talking about photons in a different thread. If you want to talk about photons we can talk there.

Speed or velocity?

Thanks for the advice but I think I need something simpler.

I fly in a spaceship on a 2d plane (for simplicity sake) in zero G. I eject a rock 90 degrees right to my forward vector. What does the equation look like if I want the final vector of the rock? I know the final speed of the rock is 100. What variables need to be known about the ship and rock?

I can fix that.
