SpaceX mission camera selector

Here is the video sequence of the latest Starlink launch I found interesting. At about T+ 5:10 (20m30s of the video) a circular cloud like formation is developed in direction next to left grid fin and then the video switches to the tank camera for a while which having no action or relevance at this ...

Re: I have an idea for quantum gravity

This is a longstanding idea already, right? Isn't the problem we don't have a way to test the theory because we can't build the theoretical particle accelerator needed because it would be too large and take too much energy? I am not sure that physists are familiar with this idea or not but I found ...

Re: I have an idea for quantum gravity

Actually quantum phenomena would be good point to start for gravity. Classical gravity model is static and it is related to mass, therefore it not a result of a dynamics. However gravity could be result of a dynamics and still can be related to a conserved entity. It is interesting to evaluate energ...

Re: See what I did

I did it orbiting and posted this version link at Dec 5. http://youtube.com/shorts/VLuojRRY33k I am still working to make the orbiting to continue forever with more attractive strength and by controlling the orbiting speed. I think this speeding is caused either by induction currents or by some hyst...

Re: See what I did

Spheres are from a aliexpress bought five years ago. Rest are from local store where they are exporting from far east. This cylender is a 40 mm ID PPRC tubing section where I carved manually the inner section. Housings used on other tests (http://youtube.com/user/sudanamaru/videos?view=0&sort=p&...

Re: See what I did

There are total seven rectangular magnets in this cylender. Three of them make a block of 25x25x20 mm where the dipole is oriented radially in 25mm orientation. The second block is 20x25x5 mm magnet aligned axially and the third block consists of a broken piece of 50x25x10 magnet get thickened by tw...

Re: See what I did

The hum is coming from the motor assembly which spinning the cylinder at 7300 RPM, corresponing to 122 Hz. This noise happens because magnets in the air vibrate this cylinder by strong forces. The cylender only contains neodymium mag ets. The motor consumes about 300 mA at 9V DC, Keeping magnets in ...

It is possible to obstruct a squid behind some tubes and force it to fire to you continously but inefficiently for several minutes. Please test it. I claim that it can fire indefinitely.

Ships would never be out of fuel unless designed before 2020

If one already have their cars never be out of fuel in real life by year 2020, it wouldn't be a futuristic game anymore if your newest model pyro cannot replenish its energy by itself. Energy centers would serve only for quick charge. Robots apperently have no energy problem as they can fire indefin...

However, I feel the same as you do. Yes, we ready to accept robots have emotion and react. So designers can inc...

Hi

There is very nice video and background music showing Dawn spacecraft simulated flyover Ceres. Bright spots are thought natural salt residues but could be damp of mining activities preceding PTMC.

Re: I am back

If I understand correctly, the ultimate goal of solution stability of the body (or bodies) is to obtain the maximum energy conversion efficiency from it with minimal energy costs. Although energy and stability are related, but not this way: In general a system is (more) stable when its energy is mi...
