    Gravity (over extremely long distances)

    What about conservation of angular momentum? If gravitons take time to reach their "targets" wouldn't planetary orbits become seriously messed up? Also, doesn't the minimum level of illumination caused by a solar eclipse lag several seconds behind the gravitational effects?

    Gravity (over extremely long distances)

    So if the Earth's sun spontaneously collapsed into a black hole, then gravitational tides would reach us immediately after the last photon emitted by the sun?

    Gravity (over extremely long distances)

    So how does gravity function according to the most recent standard model? Is there particle interaction? I remember reading about gravitons years ago, but it seems unlikely to me that any particle could be involved, I mean try to imagine a mass emitting so many particles that the universe could...

    Gravity (over extremely long distances)

    This question may be a little vague or difficult to answer definatively. Take an empty universe, completely bereft of all energy and matter, with the exception of two neutrons. These two neutrons are placed a trillion light years apart from each other and each have no velocity with respect to...

    How Does Photon Momentum Exist Without Mass?

    I have one more method of determing a quantum particles location I was wondering about. Assume first, that time travel is possible. Now, a light bulb, floating in vacuum, is given enough electricity to produce just one photon. A scientist places one molecule of h2o2 (photosensitive) one meter...

    Strange counterintuitive probability problem

    Could someone please tell me if this is true or not, and if it is true, help me to understand why? This is a famous demonstration of how hard we find it to work out probabilities. When it was published in Parade magazine in 1990, the magazine got around 10,000 letters in response92% of which...

    How Does Photon Momentum Exist Without Mass?

    "Photons are not particles in the sense of classical physics. If they were, the state of a photon could be represented by six numbers (3 for position, 3 for velocity). It can't. Photons are much more complicated. In particular, they don't even have a well-defined position. So they are neither...

    How Does Photon Momentum Exist Without Mass?

    1. Classical momentum is derived using this formula: p=mv. The mass of a photon is zero, so then, how can it have momentum? Does it have some other kind of momentum that differs from classical momentum? 2. Photons are particles, why then do they travel in a wave? I've heard it's because...
