Thoughts and explanation about time travelling through a black hole?
A black hole curves the space-time fabric to an extreme point called singularity. And since space and time are working together, according to the theory of relativity, curvature and gravity also affect time.
This is best illustrated by one person (call them Unlucky) falling into a black hole while another person (call them Lucky) watches. From Lucky’s perspective, Unlucky’s time clock appears to be ticking slower and slower. This is in accordance with Einstein’s theory of general relativity, which (simply put) says that time is affected by how fast you go, when you’re at extreme speeds close to light. The black hole warps time and space so much that Unlucky’s time appears to be running slower. From Unlucky’s perspective, however, their clock is running normally and Lucky’s is running fast.
What if we can breathe in space but the Government just tells us we cant so that we dont try to escape.
Studying physics is essentially being taught a simple structure, and then told ”actually, scratch that, the truth is actually far more complicated” over and over again until we reach the point where we still don’t know the truth, only that we do not have it.
Chemistry: Burning up alcohol

The edges of this flame are black. No camera trickery, no special effects. What’s going on here is down to some interesting science and some excited electrons.
When you burn sodium it emits a monochromatic yellow/orange light. This happens because when sodium heats up, electrons in the atom’s orbitals become excited and they jump up to a higher energy level. When they drop back down to their original energy level they release a photon of light of a specific wavelength, which for sodium is yellow/orange.
As well emitting photons, sodium atoms also absorb photons of the same wavelength. That means if you have a light source emitting the same monochromatic light (like the sodium street lamp which we have here) the sodium atoms in the flame will absorb the light making the flame look dark.
