This article describes how scientists may have evidence that black holes don't exist due to new equations of Einsteins general theory of relativity. If these new scientists are correct then what we know as black holes might just be dense clumps of matter (Flam). The fact that scientists are able to add on to Einsteins theory with newer more advanced mathematics isn't an outrageous idea, but actually very plausible. Not all astrophysicists are going to agree with this, but if researchers can work more on the theory and improve the equations even more, it'll be almost impossible not to believe them because you can't fight proven math.

The article explains that there are millions of black holes in our galaxy due to scientists new research; "To get their estimates, they used existing information about the distribution of stars: where they exist and how big they are. The estimates also told them how big they could expect black holes would be after the massive stars collapsed" (Glowatz). Scientists are using already proven facts about stars and where they are to predict where black holes could possibly be in our own galaxy. This information helps prove my already existing thoughts that black holes do indeed exist. The idea that scientists can use things we already know for sure, like the placement of stars, to predict where black holes could be in our galaxy makes a lot of sense.

The video explains how black holes form from dying stars that are large enough and dense enough to collapse into themselves, which is how they form. Black holes are known to be in our universe, but singularities, which are defined as a single point in space that is infinitely dense yet have no surface area or mass, are what scientists are unsure about (Kurzgesagt). Black holes are a very interesting thing for scientists to talk about which can bring up many arguments. This video does a good job explaining what they are and how they work to help the viewer have a better idea exactly what scientists are talking about.

This article describes how black holes are made and how they affect space around them, "We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion ... As the attracted matter accelerates and heats up, it emits x-rays that radiate into space" (NASA). This information is very useful for the side that believes black holes exist. NASA saying that they can infer the effects of black holes by viewing how they change nearby matter is a very big step in figuring out if black holes are real. To me, it would be very difficult to argue something that NASA says, because they are if not the biggest, one of the biggest aerospace research places in the United States.

The article describes how there are two main lines of evidence to support that black holes exist. One being by observation of how black holes effect the space around them. Scientists can see this by looking micro-quasars, also known as x-ray binaries. The objects being observed emit strong x-ray which can be seen by Earth. The other line is theoretical, stemming mainly from Einstein"s theory of general relativity. His theory describes many things about gravity, which is a main factor that goes into the existence of black holes (Koberlein). These two different lines of evidence are very convincing, especially coming from an astrophysicist, who knows what he's talking about. The idea that researchers are observing what they believe to be x-rays that are caused by the effect black holes have on surrounding matter is a big deal in figuring out if black holes exist. It makes a lot of sense that we would be able to see such a thing since black holes are said to have such a strong gravity. Since they have a strong gravity, objects or matter that goes near the horizon would be effected and we would be able to see that effect.

The article describes how black holes can be believed to be true due to, "Their effects on nearby light and matter, however, have been seen so often that we are forced to conclude that black holes really do exist. To some extent, we can even understand how they are created. When a massive star dies, it leaves behind a "compact object." If the mass of the residual compact object is more than about three times the mass of the Sun, then nothing can hold back gravity and the residual core of the death star becomes a black hole" (Corbel). Black holes are such a dense object that they will affect the light and matter around them, which is something researchers can see and use to further understand exactly how black holes work. This is a very neat thing that were able to do now thanks to newer technology and better mathematicians. Observation is a very appealing thing when trying to decide if something is real or not, because many people don't believe something until they see it. Corbel, Stephane. "Watching black holes spin."
