ive heard that light might have mass. ive also heard that wen something reaches the speed of light its weight is almost infinite. so if light had mass would it be heavier than a black hole? if light doesnt hav mass the forget about evrythin i jus said lol. i want some real answers

Light itself, (the photon), has no mass.
The energy it carries does.
Thats why they say the photon has zero rest mass.
That's why the "impact" of a high energy photon can be measured.
The 'mass` of the energy, is not subject to the effect you mention, but is derived from Einsteins equation.

No.
Light is composed of photons which have magnetic and electric properties but not mass. The photons are travelling along a wave which has been electrically excited by the source (In this case a star although the same principle applies to a simple flashlight). The photons oscillate along magnetic lines reaching outward from the source. Magnetic lines are created when charged particles are aligned in a single mode.
An electric field is created when there are unbalanced opposite charges. Such is the case with electrons. Every electron is a magnet with a north and south pole.
Magnetic lines of a magnet are constituted of what are called ether magnets (or ether particles). This is the field visible when you sprinkle iron filings around a magnet. These magnetic lines do not travel or have velocity. They align themselves when charged by the source so that the N/S poles of one particle aligns with the N/S pole of the ones ahead of it and behind it etc.
Photons travel on these magnetic lines. The electrons constituting the line (which would technically hold the mass you refer to) does not actually move.

In reality, No, it does not. Light is nothing but a certain wavelength of energy, much like sound. Light is made up of photons. Photons are massless particles.

Tecnically, NO, ...but light is still affected by the gravitational field of a planet of other massive body.
Light is deflected by a gravitational field.....the amount has been measured.

NO, light is a form of energy traveling in a wave.
