How to create a mini black hole? How do we detect black holes? Do black holes really exist as described by relativity? Explain the formation of a black hole. What happens when two black holes are about to collide? What are the Black holes?
“Intermediate-Mass Black Holes are difficult to observe,” explains the GSSI researcher, “the current observational limits do not allow us to say anything about the population of IMBHs with masses between 1,000 and 10,000 solar masses, and they also represent a headache for scientists in ter...
In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression, thanks to ...
do everything possible to avoid overlaps). I usually fill the old holes with something like JB Weld or epoxy steel, and poke steel wool in the hole as well. It’s essential to fill the holes completely with some sort of hard filler; do so by poking the epoxy and wool...
Here we go! Let's try to directly observe something abstract. This will probably be harder than observing concrete objects; be patient, and feel your way around gently until you start to get the hang of it. Exercise 1 Repeat the previous exercise, staying tuned into felt senses as you mak...
There's a subtlety here. The outside observer will observe the increase in the size of the black hole and this happens in a finite time, but that's not the same thing as seeing the infalling object cross the horizon - light from that event is still trapped at the horizon. There's...
eliminate known bad programs, and step up surveillance on unknowns. Only if an unknown program attempts a suspicious connection does the firewall kick in to stop it. That’s not something we can test, since we don’t writezero-day malware, but we can observe this functionality during malwar...
However, Inflation solves some important mysteries that we do not know how to fix otherwise within ΛCDM. As mentioned below Equation (3), the structures that we observe today were not in causal contact in the past. We say that they are super horizon scales. Structures that are larger than...
We mentioned earlier that astronomers have estimated the number of stars in the Milky Way from measurements of the galaxy's mass. But how do you measure the mass of a galaxy? You obviously can't put it on a scale. Instead, you use its orbital motion. From Newton's version of Kepler'...
Black holes are known for their voracious appetites, binging on matter with such ferocity that not even light can escape once it's swallowed up.
