General relativity is thought to predicts that certain systems like binary stars should emit gravity waves as they orbit each other. But as far as I know, we have never detected any, even with our most sensitive equipment.

Is there perhaps something wrong with this prediction, or is general relativity incomplete in some way? Do gravity waves simply not exist?

If gravity is the natural phenomenon by which physical bodies attract with a force proportional to their mass

why do two objects of different masses fall to earth at the same speed?

Dear /sci/,

what proof, physical or mathematical, do we have for the existence of gravitons?

so i was wondering. a lot of /sci/borgs are atheists, but is there anyone who is actully some sort of spiritual?

if yes, what do you believe/practice/think?

i only think that there is a logic to the universe and that there is some greater meaning to everything. (yes i do drugs)

Hi /sci/
So, I heard you guys don't like 'Free energy'
I know the laws of physics, I know how the conservation and conversion of energy>heat/electricity works, and I do know that one cannot simple 'Create' energy.

But with every known scientific formula dealing with energy, there is one obvious outstanding flaw to said laws of conservation.

The existence of energy and mass by itself contradicts any of these laws. Actually, the laws of energy and this fact may very well go hand in hand mathematically, but how the laws of conservation are perceived perpetuates the belief that somehow energy is in short supply or is not infinite and will eventually 'End'. If this is your mindset, you are wrong.

I'll make this short and sweet.
Tl;dr: Gravity does not require fuel, but it is a form of energy, as it can create heat from nothing. Two gigantic motherfucking balls of ice at zero goddamn Kelvin will warm up if introduced to each other in space by either crashing into each other or orbiting around each other.
My argument is that 'Free energy' by means of creating electricity constantly through gravity or magnetism is not only possible, but being done fucking everywhere, including my own room.

So /sci/, stop being so abrasive to the idea of 'free-energy', even if it is a mis-interpretative phrase that is in need of updating. You're all sounding like bible-thumpers, dismissing these abundantly obvious universal properties of mass and energy just because they contradict what academia has taught you.

are there any theories about how the water vanished from mars?

hey /sci/, brief question:

What amount of gravity from a planet is too powerful to allow complex life? I assume that if gravity is too powerful, complex life would not develop, as if it did/tried, the animals bones would shatter under the force, or blood would be unable to flow efficiently through the organisms body.

On that note, how little gravity can there be for a planetoid to be unable to hold an atmosphere?

how does gravity work
does anyone actually know
