How can a photon “push” something in space if it has no mass?	1
Since gravitational waves ripple in space time they cause space to expand and contract, but because of the time component of space time, does this also cause some form of time dilation or contraction?	1
If the ecosystems by geothermal vents suddenly disappeared, would this affect the rest of the marine life in the oceans?	1
If a very massive object got near a black hole, would the event horizon bend towards the black hole in that area like a little dent in the black hole since the massive object would be helping “pull” the light out of the black hole?	1
If spinning objects drag space time along with them, how does this affect the passage of time? Primarily at a black hole or neutron star?	1
Would the only way to tell the difference between being on earth or being on a rocket accelerating at 9.8m/s be that on earth you experience gravitational time dilation?	1
If white light hits an object and then it turns green, does this mean that the it absorbed all of the photons that make up white light and only re-emits a green photon? If so, why doesn’t it re-emit all the other photons.	1
Could a black hole be thought of as the ultimate state of low entropy, since all the matter is packed into the singularity giving the matter the least amount of randomness possible?	1
I’m trying to find the Schwartz child radius for myself and I am really confused about the units and what gravitational constant is.	1
Do particles interact with the Higgs field via the Higgs boson like how electrons interact with the electromagnetic field (or photon field) via photons, or is the Higgs boson merely an excitation of the Higgs field, not involved in the process of giving particles mass?	1
