Don't you agree that at some point of time the circle would stop increasing its size? Since there is a limit of energy, there must be a limit of size for the circle of light. Let's say that density falls as you said and the probability of finding a photon decreases. It means that at some point...
Hi, I've been asking questions about light here for years, and I still don't understand the limit of propagation of light, does anyone have advanced on this field?
I really would like someone to explain me how it's possible for light to propagate forever, since it's probably emitted in perfect...
people say that gravity is not a force, that it's rather a distortion of space-time
so objets that go to a gravitational center are actually just moving through space in linear direction
but there is a problem in this theory
shouldn't objects go to the center in constant speed? why are they...
It works for short distances but when I ask myself about a light source at a distant galaxy creating light waves... I'm not sure if it would reach us. Seems impossible for the waves to cover an absurd bigger area without any consequence. How can exist energy for this? You can't assume that the...
Is there enough energy in a light wave to make it spread forever? So it gets bigger and bigger reaching all spots in the universe? Seems impossible because of the lack of energy for this. I don't understand why people do not question themselves about this.
In case light propagation is in form of waves, do you agree that the waves get bigger and bigger as far as they move away from its source of origin? Do you agree that this is impossible except in case whe say that the wave one day would get "thinner" (maybe "weaker" would be the word) and at...
There is a high chance of you being right, but in High School teachers tell us to make exercices showing lines of little bullets reflecting on mirrors, is this wrong?
According to Einstein light would be a particle and a wave.
So I infer that it propagates in vacuum in form of waves of little bullets (particles).
This explanation is very insuficient.
So tell me how do waves increase in size since it's made of little bullets (particles)... a wave gets...
Since gravity accelerate things (even with some people saying that it's not a force) there must be a consense that it adds energy to things. There are even hydroeletric power plants generating energy everywhere. So where does the energy of gravity come from? Is it spontaneous generation of energy?
Hi, I've been struggling for a long time to understand the propagation of light. Here are my key problems:
- since a star can be seen from any direction, it means that photons are emitted in all these directions, which are infinite, how is this possible? infinite photons?
- in case there are...
the problem is that photons are emitted in all these infinite directions...seems impossible, since the number of photons are finite like you said
regardless of where you are, when you look at the source of light you would see it... seems that something isn't well explained there
I still don't understand how light can be emitted in infinite directions.... seems impossible... at least if it's a particle... if it was a wave that would be better explained....
just think about observers standing billions of light years away in millions of directions... there would be...
Hello, people say that light has properties of particles and waves. Ok, but how exactly?
We have the principle of rectilinear propagation of light as a law on Physics. Light would be a particle that propagates in a direct line pointed to all directions with origin on the source of light.
The...
Any force, it seems magic when it comes to someone telling me that two objects separated by vacuum can attract each other. It seems illogical to me. I would like to have an explanation in details about how exactly forces of attraction work, they all seem like illusions to me.
