Except two planets crashing into each other would raise one hell of a dust cloud. Nothing like pool.
Given enough force, you can pulverize two billiard balls as well.Except two planets crashing into each other would raise one hell of a dust cloud. Nothing like pool.
But in case of huge mass, you don't really need that much force. Just enough will do. Inertia of the massive planet getting struck by the runaway planet plays a huge factor too.Given enough force, you can pulverize two billiard balls as well.
If an alien civilization is advanced enough to make a Dyson sphere, we won't need the JWST to show it... because they'll probably make their presence very obvious!
They are probably hiding from us puny humans. Coz we always find a way to attack where they are the weakest. We still have Will Smith!Unless they are hiding from a sinister more powerful civilization

If it breaks away from the gravity well of its parent, it already has enough force. We are talking about rogue planets roaming freely through space.it requires a tremendous amount of force to get a planet sized mass going...

I didn't. So my understanding could be flawed. Feel free to poke holes in my theory Maybe our discussion helps us discover how to enter hyperspace!I did learn rudimentary planetary mechanics in university physics
boost? why?In related developments NASA/SpaceX to study if they can boost Hubble using Dragon.
boost? why?
thought hubble's orbit was stable?
nothing has changed in ~20yrs?Hubble LEFT - James Webb - RIGHT.

scott manley went over the dragon capsule trying to service hubble. the main problem is the location of the thrusters in the nose and the hubble connector being in the base end. there isnt a great way to approach it without the thrusters spraying all over hubble potentially knocking it off whatever stable orbit it is in now. that and the need for an arm to grab hubble needing to be tested and certified. the space shuttle with it's big bay and arm was surprisingly significant.Well relatively. It's still supposed to go down by the early 2030s I think.
If SpaceX can make Starship work a servicing mission in the 2030s wouldn't be out of the question. Maybe as a proof of concept for other future orbital telescopes.
The size of it is so vast/immense, I'm guessing that it would take hundreds of years to see any changes from our vantage point.nothing has changed in ~20yrs?
for speed of light, things move slow.

5-light years wide and 8-light years tall.I read that it's something like 55 light years long!
geez..5-light years wide and 8-light years tall.
