There are numerous things in physics which we are not certain about. But the speed of light? We are so certain about it that we even defined the length of 1 meter using it. It is the distance traveled by light in 1/299792458th of a second in a vacuum.
As discussed in the above video by Veritasium, no one has ever measured the 1-way speed of light. We have always calculated the two-way speed. Therefore, if light travels at different speeds in different directions, it would imply that our value of c is incorrect.
Due to the restraints provided by general relativity, it is impossible to calculate the one-way speed of lights, the problem being syncing clocks. …
A problem about spinning Black Holes that have been making scientists uncomfortable is that of naked singularities. Black holes can spin so fast that it may be possible to see into the singularity. More on that here.
However, I have a hypothesis that may solve the existing problem of naked singularities.
The size of the Event Horizon is equal to the Black Hole’s Schwarzschild radius, or
with M as the mass, G as the Gravitational Constant, and c as the speed of light. This yields the radius of the Event Horizon.
As I have discussed here, the speed of spin of a Black Hole can decrease the ISCO (Innermost Stable Circular Orbit) around a Black Hole, making objects able to have a stable orbit closer to the Black Hole. This spin, however, can increase to such an extent, that the ISCO will be smaller than the Event Horizon, and thus light can escape from it and we could see the singularity. …
Black Holes are really mysterious and amazing things. But something more mysterious and amazing is a spinning Black Hole. With non-point singularity and particle emission, they are just something that sounds like it shouldn’t be possible. A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry.
The First Law of Motion states that something that is still, wants to stay still, while something in motion wants to stay in motion.
One of the most mysterious objects in space are Black Holes, dark voids in space formed by the collapse of massive stars. I’ll be covering most of the topics of interest in this story.
The idea of the existence of Black Holes was first given by Indian-American Astrophysicist Subrahmanyan Chandrasekhar. On his way to England, to study in Cambridge, he calculated the maximum mass a white dwarf(dead star) could have. Everyone else thought there was no maximum, but Chandra showed that there was a limit to the gravitational force normal matter could withstand. …
