In the gravitational equation the force is inversely proportional to the distance, as the distance gets bigger and bigger the force approaches zero. We can notice that force approaches zero “ a real number” but space approaches infinity” unreal number”
In the number line when moving to the right from for instance the number 3 to the number 4 there is a possibility of infinite numbers greater than 3 and less than 4 instead of reaching 4 a moving object could move infinitely to reach 4 and will never reach it. it will move for instance from 3.4 to 3.49 to 3.499 to infinity regardless its speed it won’t reach the 4 an object will jump from a number to a nearby number gravity jumps to zero while space continues to infinity
Light is massless but it has mass characteristics since a photon is an entity and a photon behaves like objects "motion" and there is light bent due to star mass as result of gravity affecting on light.
There is not solid mass in photon but energy behaving as mass or mass-energy, in fact a true massless object doesn't exist .If light is energy then it has mass since mass and energy are interchangeable the true massless object is nothingness no mass no energy
A photon is energy with speed c=3x10^8 m/s and a specific relativistic mass.There is not such thing as maximum speed since the equation will satisfy only for nothingness and zero rest mass can't be assigned to the relativistic equation.
Light travel with c speed only, no matter the force on it, since it doesn't have a solid mass.
According to Albert Einstein and if mass and energy are interchangeable then light is in fact massive since it contains energy.
In calculating escape velocity from a mass gravity force of this mass at infinity is considered to be zero an object has specific amount of kinetic energy starts with the escape velocity from mass and stops at infinity If gravitational force at infinity equals zero then we have a real number "zero" assigned to unreachable quantity "infinity" making it reachable.The gravitational field is real and it has an end equals zero there should be an end for infinite space. I believe that infinity is unreachable and mass existed at a specific moment and spread its gravity and still spreading its gravity towards infinity.
Even though in reality you can't reach infinity it could be a thought experiment that is if gravity effects decreases continuously we have a limit for that decrement which is zero effect then gravity effect in fact has a limit but space doesn't so what happens at that limit when gravity force equals zero space would still be increasing.
It's only if gravity still spreading into space and didn't reach infinity and still spreading.
For each mass it has a real number range of gravity, beyond that its gravitational force doesn't exist and it is still spreading out and making curvature to space
Mass curvature for space is a process it starts at the existence of mass continues with the speed of light c and will never reach an end.
The idea is four neodymium magnets at balance due to equality in attraction and repel force when the air compressor #1 moves from right to left it rotates the wheel #3 and the wheel vibrates the magnet it is contacted to causing imbalance to the system of the magnets and causing the magnets # 6 to move from side to side as long as the magnet vibrates
Will this hacksaw design work? Would any one buy this hacksaw ? So far I was able to list these benefits: 1) In my machine there are two springs to supply with enough pressing for easier cutting. 2) My machine has two blades to cut from both sides at the same time for faster cutting. 3) The blades in my machine are closed solving the problem of a loose hacksaw and causing cutting to be straight forward. 4) It is easy to use and can be used by anyone ; there is not a need for an expert to cut straight forward. 5) The time the two blades last before replacement is double the time is needed for an ordinary hacksaw;we have two blades and they share cutting. 6) Using my hacksaw we can focus on moving the hacksaw and neglecting pressing; this will enable us to cut with faster speeds.
