    Why doe glass get hot if the photons aren't absorbed?

    Ahhh it was staring me in the face. Knew there would have been a simple answer, thanks a lot.

    Why doe glass get hot if the photons aren't absorbed?

    My understanding of glass is that it is transparent because photons do not have enough energy to raise the electrons in the atoms to the next energy level, thus the photon is not absorbed thus it gets through and we see it as light. But if the photon isn't absorbed, thus not leaving it's...

    Are we travelling slower through time due to the Earths orbit?

    Well we're going forward through time, like, stuff happens...so we're not, not moving through time, and stuff doesn't happen that has already happened so we're not going backwards through time. Which must mean we're going forward in time. And if we're going forward in time...we must be going...

    Are we travelling slower through time due to the Earths orbit?

    How fast are we moving through time please?

    Are we travelling slower through time due to the Earths orbit?

    Is it that faster we move through space, the slower we move through time? Is it that we're moving slower through time than if the Earth wasn't orbiting anything? And on a wider scale like, the Sun orbiting the centre of our galaxy, and our galaxy moving through space. How would time be...

    Why does light allow us to see things?

    It's weird the thought that, what we see isn't actually how the universe is, just how our eyes interpret it. Like if our eyes evolved differently we'd have a completely different view of the universe init?

    How Does Light Move and What Propels Photons?

    Yeah, yeah this is what he said. It was in a talk he gave, thanks for that, it's on youtube in a video called 'A night with the stars'. I wish I could spend a week with Brian Cox I'd have so many questions.

    How Does Light Move and What Propels Photons?

    So the movement of one electron from one orbit in the nucleus to another gives off one photon? How many different orbit levels are there for an electron to have? Cause I was once told that every electron in the universe has a different one, and once one changes energy levels, every other one...

    How Does Light Move and What Propels Photons?

    Ummm, as far as I understand it something moves through space at the same speed forever unless its path is altered by another force? I'm new to this I'm sorry if it's a stupid question. But as I think about it, the Earth, fundamentally moving through space because of energy is received from...

    How Does Light Move and What Propels Photons?

    Or how does light move? There's a source of light, for example a torch but what is it that propelled the photons into my eye from the torch? I'm new to this so I don't know, I mean I know light is a wave but it's also a photon init, so why does that photon move?

    Why does light allow us to see things?

    So the EM radiation changes depending on what it hits and that's how we see if something is red/blue. And is something actually a colour or is it that, it's only that colour because of the frequency of the EMR? What is it about the object that changes the frequency of the EMR for it to appear...

    Why does light allow us to see things?

    But is it that the photons carry electrical information about the object it just hit and deliver it to our eyes?

    Why does light allow us to see things?

    I don't understand, light is just a form of energy. Why is it that I can see the things when light hits me in the eyes?

    Particle accellerators: How do they get the particles to hit eachother?

    I've never understood how they do this. Particles being extremely, extremely tiny, how do they manage to send them around the accelerator a million times until they reach almost the speed of light, then when they reach that speed, crash them together? My question is how do they get them to...
