Science knowledge - Black hole facts

Interesting cool amazing random black hole facts for kids

#1

The massive gravitational influence of a black hole distorts space and time in the near neighborhood. The closer you get to a black hole, the slower time runs. Material that gets too close to a black hole gets sucked in and can never escape.

#2

Material spirals in to a black hole through an accretion disk, a disk of gas, dust, stars and planets that fall into orbit the black hole.

#3

The “point of no return” around a black hole is called the “event horizon”. This is the region where the gravity of the black hole overcomes the momentum of material spinning around it in the accretion disk. Once something cross the event horizon, it is lost to the pull of the black hole.

#4

Black holes were first proposed to exist in the 18th century, but remained a mathematical curiosity until the first candidate black hole was found in 1964. It was called Cygnus X-1, an x-ray source in the constellation Cygnus.

#5

Black holes do not emit radiation on their own. They are detected by the radiation given off as material is heated in the accretion disk, and also by the black hole’s gravitational effect on other nearby objects (or light passing black Holes affect time).

#6

Gravitational time dilation is possible in black holes. Just as a clock runs a bit slower closer to sea level than up on a space station, clock run really slow near black holes. It all has to do with gravity.

#7

They can be infinitely big. Or so some theories state. But without a doubt when it comes to something of this nature there are scientists on both sides of the fence.

#8

The nearest black hole to the Earth is 1,600 light years away. Our galaxy is covered in black holes but the one most likely to destroy our measly planet is still well beyond our solar system’s borders.

#9

Stay away from the event horizon. The “event horizon” as it is called in physics, is the border of the black of hole. It’s the point of no return. Before that point, you can still escape. After that point…not a chance.

#10

There is a massive black hole at the center of the Milky Way galaxy. It’s 30,000 light years away and is over 30 million times as massive as our sun.

Garlic breath - Why does garlic make bad breath?

Garlic is a plant in the onion genus. It has been used both for food flavoring and traditional medicine. It is also a very good source of manganese, selenium, vitamin C, and health benefits. However, it often causes our breath smell bad when trying it.
Why does garlic make your breath smell bad?
There are a few things going on to cause this bad smell, but principally the root cause is various sulfuric compounds from the garlic.  Initially, most of the bad breath resulting from eating garlic comes directly from the sulfuric compounds introduced into your mouth.  Not only that, but garlic actually promotes the growth of some of the microbes in your mouth that already cause bad breath, which further exacerbates the problem.

You may have noticed that even if you brush your teeth, rinse with mouthwash, and other such methods to clean out these compounds and various microbes from your mouth, the bad breath caused by garlic still remains to some extent.  This has to do with the fact that some of these sulfuric compounds get metabolized, eventually making their way into your blood stream.

The primary smelly culprit here has been found to be allyl methyl sulfide, which is passed into the blood during the digestive process.  Once it’s in your blood, it eventually gets passed out of your body through various bodily excretions, which includes being exuded through your pores and also passed into the air that fills your lungs. So as you breathe, the air goes into your lungs and is contaminated by the allyl methyl sulfide; this in turn causes your breath to continue to smell even if you’ve cleaned your mouth out.

As mentioned, this sulfuric compound will not only find its way into the air in your lungs, but also will be exuded from your pores.  This ends up causing your whole body to smell, not just your breath.  As you are excreting this sulfide, you essentially are wearing a stinky perfume.  This effect lasts as long as it takes for your body to get rid of the stinky sulfuric compounds, which can be anywhere from a few hours to as much as a day after eating the garlic.

Because of the fact that the smelly sulfuric compounds from the garlic are in your blood, there is little you can do to immediately get rid of the smell from eating garlic, other than to mask it with a stronger smell.  However, many people swear by parsley and sprigs for getting rid of garlic breath, which is why particularly parsley is often included in many dishes that contain significant amounts of garlic.  Another popular cover up is to drink hot mint tea.  Further, drinking milk while eating something garlicky has been shown to reduce bad breath and does an even better job if you drink the milk while the garlicky item is still in your mouth and swish it around.

Tiger information for kids - What do tigers eat?

Check out for some tiger information for kids, get to know what and how do tigers eat. There will have something that might surprise you. 

What do tigers eat? What does a tiger eat?

Tigers are carnivores, meaning that their diet consists of meat, flesh, and fats off of animals that they catch. This is where they get all of their protein and other dietary requirements in order to conduct day to day activities.

It’s hard to say whether or not Tigers have a preference in what kind of meat they eat or if they are just eating what is available and easiest to catch. They will eat everything that they can catch and kill. This often includes boars, wild pigs, bears, buffalo, wild cattle, dear, antelopes, and even weak or young elephants. When large prey is not available, they are known to feast on lizards, crab, toads, birds, and fish.

Tiger Diet depends largely on what is available in the place they live

Siberian tigers: What do siberian tigers eat? This species’ diet ordinarily consists of about 50% wild boar meat. If they cannot get their paws on some wild boar they have been known to eat elk, deer, lynx and sometimes even bears. If large sources of meat are not readily available, Siberian Tigers will eat rabbits, fish, and any rodents they can get to.

White tigers: What do white tigers eat?  White Tigers are one of the best hunters because they can follow their prey even if they attempt to escapes into the water. This allows them to easily feat on monkeys, wild cattle, deer, and birds. Since they don’t hunt daily, they will eat until they physically cannot fit any more.

Sumatran: What do sumatran tigers eat? Being a critically endangered species, there is not as much known about this specific species. We believe that their diet consists largely of local birds, fish, and monkeys. They are not good climbers and are limited to prey that comes down to ground level.

Bengal:  What do bengal tigers eat? Native to the savanna regions, they will hunt any livestock they can take down. They commonly feast on buck, wild pigs, and birds. This species is also one of the few that will not have a meal every sing day, so they eat well when they do have a meal.

Malayan: What do malayan tigers eat? This species boasts the ability to take down just about anything within its hunting range. They are known to eat wild boar, baby elephants, and sub bear. They are extremely accomplished hunters and will kill anything that can’t kill them.

How much does a tiger eat a day?

Various field studies have estimated that mature wild tigers and lions consume between 10 and 25 pounds of prey a day. This is between 4 and 7% of their body weight. This is only a theoretical average. In the wild tigers and lions will gorge up to one hundred pounds at one sitting and then fast for many days.
