How can a small particle say a neutrino travel ALMOST at the speed of light when it would take an infinite amount of energy to travel at the speed of light?
JakobB
Firstly, it takes an infinite amount of energy to accelerate an object with 'mass' to the speed of light. A massless particle removes that energy problem.
Secondly, approaching the speed of light is not actually much of an issue for even a particle with mass. The Large Hadron Collider accelerates particles to just 3m/s below the speed of light, 'almost the speed of light' by any definition. While it takes an immense amount of energy, it can still be done.

How is it possible that negatively charged beta particles are emitted from a positively charged nucleus during nuclear decay?
An electron (negative particle) and an electron neutrino (neutral particle) are released when a neutron (neutral particle) changes into a proton(positive particle) therefore in order for neutral charge to create a positive particle it also has to create a negative particle to balance it out.As a significant amount of binding energy is released, the electron is ejected at high velocity as beta radiation while the much more massive nucleus containing the newly created proton recoils with very low velocity. The neutrino having almost no mass is ejected at almost the speed of light, but is nearly impossible to detect except by implication from the "missing momentum".Basically beta particles are ejected from the nucleus by conservation of momentum before and after the decay event.

What is mass of a particle when it moves with velocity of light?
Fasten your seat belt . . .-- If the particle has any mass when it's not moving, then that mass becomes greaterthe faster the particle moves.-- If the particle could be pushed to the speed of light, its mass would be infinite at that speed.-- But in order to make the particle move faster, you have to add energy to it. The more mass it has,the more energy you have to give it in order to make it move faster.-- Since its mass grows as it moves faster, the amount of energy it takes to make itgo faster also grows.-- If its mass is growing toward infinity, then the amount of energy you need to make itgo faster is also growing toward infinity.-- Since the mass would be infinite at the speed of light, you would need an infinite amountof energy to boost it to that speed.-- You don't have enough energy available to do the job, and you can''t get it.

An infinite number of pulleys has an infinite amount of friction, which means you cant move the system no matter how hard you pull.
Which particle has the least amount of mass?
The 'rest mass' of the photon is zero ... but the photon is never at rest, and it has plenty of mass at the speed of light, at which it is always traveling. so that let's the photon out. Amongst particles that actually have rest mass, but not much of it, the neutrino probably has the least.
