Fuel Space

AI Thread Summary

To estimate the amount of fuel needed to launch a specific weight into space, the Tsiolkovsky rocket equation is a useful resource. The discussion highlights the complexity of fuel requirements, noting that additional fuel increases the overall fuel needed due to the extra weight. While no exact formula is provided, participants agree that a rough calculation can be derived from the equation. Understanding the relationship between payload weight and fuel mass is crucial for accurate estimations. This topic emphasizes the challenges of rocket design and fuel efficiency in space missions.

Is there a ballpark or rough formula to get x lbs into space how much kg of fuel is needed to do so? I know that the more fuel you have the more fuel you also need just to carry the extra fuel!

Not that it is a final answer to your question, but an equation that can help you find the answer by yourself: http://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

Thread 'Light speedup question'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
