That's what I meant. I know that the gravity acts within the horizon. So, how would the radiation escape it in the first place? Merged post follows: Consecutive posts mergedAnd, can someone elaborate on how black holes disintegrate? What are the after effects of such a disintegration, if any?

The radiation won't be sucked back in due to the immense gravity? I mean, light gets sucked in!

Black holes can radiate? They have so much gravity that they suck in everything in their event horizon right? Even if they do radiate stuff, it would just be sucked in again!

Is there an end to a black hole? That is, what would happen if it died? Is there a limit to the amount of mass a black hole can suck in(so as to say)?

I wanted to know if you're against the whole idea of thinking for oneself, and that one doesn't always need a higher power to go on the right track.

You've sort of forgotten that scientists work really hard to make even one single statement about any phenomenon. You've, I think, imagined a possible explanation. It requires more than a gut feeling to prove something.

Hey, come on. Don't say things like these in a thread meant for string theory! Who knows? You've no proof that strings don't exist.

How is the energy conserved in a process like splitting of strings?

I had asked this doubt somewhere else. The answers I received weren't exactly satisfying. Can you perhaps elaborate?

Well, could you welcome me to the 21st century by elaborating on the modern concept of a photon?

The momentum without mass. And, how does 'energy' travel through 'vacuum'?

One of their properties is energy. The other, momentum. Momentum without mass. Energy without a definite boundary. Doesn't add up, don't you think?

Just to be clear, 'they' possess energy? So photons are entities with no mass. But, they possess properties such as energy?

I've a few elementary doubts on the concept (let's call it that) of photons. First of all, we say the 'rest' mass of photons is zero, when actually photons don't exist at 'rest'. And, in another thread, one of them had pointed out that the mass to travel at the speed of light must be identically zero. Would that mean that the mass of photons is zero even when they're travelling at 'c'? Do we define a boundary for photons? As in, there is a certain boundary for each photon, outside which the energy level is minimal?

So, as the frequency changes, the color of the light should change. Does this happen? When lasers are bounced back from distant objects, if the frequency etc change, shouldn't the information being gathered have disruptions?

There are more number of magnetons as you put two magnets together. This means that there is more density of entities that cause magnetism. This does increase the power. But, not double it, so as to say.

According to Einstein's assumption, light always travels at 'c'. But, according to him, only the relative velocity changes. Isn't this a wrong assumption? Because, everything has to gradually lose energy. Won't photons dissipate an infinitely small amount of energy as they move, making them lose some energy? Second part of the question: Will gravity affect the movement of photons? Because, if they have zero mass, only then there's no gravitational effect. This is due to considering their 'rest' mass as zero. Shouldn't it just be negligibly small?

What about the continuum? Isn't that a possible aspect?

Isn't 'zero' mass here being referred because the mass is negligible? Or is it that the mass is theoretically zero. With zero mass, I doubt energy can transport itself through vacuum. That is, energy is transferred only when an entity with lower energy state is found. Only a particle can transport energy, right? Even when we talk about waves transporting energy, its actually particles in motion.

There's no paradox. It's just the energy levels of photons and electrons are different. Obviously, electrons don't move at the speed of photons.

MSTCkid's ideas are conflicting. You're on two sides. When we consider a closed system, it's because strings vibrate with discrete frequencies for different objects. And, objects do have a boundary. But, the surface strings are always open looped and interact with other strings with different frequencies. Maybe, the strings are able to sustain the frequency because they're continuously interacting with each other, creating sort of a continuum, and with the surroundings.

You're not considering basic laws of Physics here. ydoaPs is right. You can't talk about collision of photons in this context either.

Light isn't energy? Woah! Could you elaborate? I know light is the visible range in the EM spectrum. But, saying light isn't energy, that would mean you're claiming photons inexistent? Aren't they packets of energy?

Light is a form of energy. Energy is radiated out with an initial velocity in the form of packets called photons. Same way, all the radiations are energy. To explain how these propagate, we consider their two alternating energy fields, namely, magnetic and electric. These by themselves don't propagate into vacuum, they travel along with the path of the energy packets, so as to say.

Could you explain why a lower state of energy cannot exist? Is it because of the electrostatic forces and the nuclear and centrifugal forces?
