00:03The farther you get, the harder the questions are.
00:06Ready? Steady! Go!
00:08What is the closest star to Earth?
00:10Is it A. The Moon, B. The Sun, or C. Mars?
00:20It's the Sun!
00:22If you rushed to say that the Moon is the closest one, you were wrong.
00:26The Moon is a satellite, and Mars is a planet.
00:312. Which country was the Titanic built in?
00:34Is it A. The United Kingdom, B. France, or C. The United States?
00:43It was built in the UK, and it was supposed to go to America.
00:48What is Brazil's official language?
00:50Is it A. Spanish, B. Brazilian, or C. Portuguese?
01:00It's Portuguese.
01:02While it's true that in most countries in the Americas, people speak Spanish,
01:06Brazil is the only country that has Portuguese as its national language.
01:10As for Brazilian, it doesn't really exist.
01:15Now, what's the capital of Spain?
01:17Is it A. Madrid, B. Barcelona, or C. Lisbon?
01:27I know you discarded Lisbon instantly.
01:29It's in Portugal.
01:30As for the Spanish capital, it's Madrid and not Barcelona.
01:355. In which country is the city of Venice located?
01:39A. Austria, B. Switzerland, and C. Italy?
01:44Tick tock!
01:47Sure thing! It's in Italy!
01:50By the way, did you know that it's built on a group of 126 islands?
01:556. How many muscles control the movement of the human eye?
01:59Is it 6, 12, or 32?
02:07The correct answer is 6.
02:107. On which continent is Panama located?
02:14Is it Europe, Asia, or America?
02:22It's in America!
02:24By the way, despite being commonly known as Panama hat,
02:28this hat actually comes from Ecuador and is also referred to as Ecuadorian hat.
02:358. What is the largest animal in the world?
02:38A. Hippopotamus
02:39B. Elephant
02:41Or C. Blue whale?

02:57Is it A. Sunny LA?
02:59B. The city that never sleeps, New York?
03:02Or C. Washington, D.C.
03:05Sure thing! It's Washington, D.C.
03:09What is the rarest blood type?
03:11Is it A. B-
03:12B. A-
03:14Or C.
03:16RH null?
03:21It's C.
03:22RH null blood, or simply, golden blood,
03:25is characterized by the absence of RH antigens in red blood cells.
03:30This blood type is extremely rare, with fewer than 50 known cases globally.
03:36The first recorded instances were observed in Aboriginal Australians.
03:4111. Which planet is known as the Red Planet?
03:45Is it A. Jupiter, B. Mars, or C. Venus?
03:53It's Mars!
03:55We call it this way for a simple reason.
03:57Iron minerals in the Martian soil get oxidized,
04:00and the surface gets a signature red hue because of this chemical reaction.
04:0612. Who wrote the play Romeo and Juliet?
04:11Is it A. Charles Dickens?
04:13B. William Shakespeare?
04:16Or C. Mark Twain?
04:19Sure thing! It's William Shakespeare!
04:21By the way, despite being super productive and writing 38 plays in his life,
04:27Shakespeare struggled with spelling since there were no standard rules at that time.
04:31Even though William went to school, spelling wasn't included in the curriculum,
04:36and everyone spelled words according to their own preferences.
04:40Shakespeare himself wrote his name in various ways.
04:44Which element has the chemical symbol O?
04:47Is it A. Gold, B. Oxygen, or C. Osmium?
04:56It's oxygen.
04:57Gold is AU, which stands for Orem, and Osmium is OS.

05:07Was it A. 1912, B. 1905, or C. 1898?
05:161912!
05:17If you didn't answer this one, well, you gotta go check out some of the Titanic videos.
05:22Here on Brightside, we've got a bunch of them.
05:2515. What is the smallest prime number?
05:29A. 0, B. 1, or C. 2?
05:37It's 2.
05:38A prime number is a natural number that is greater than 1
05:42and cannot be expressed as the product of two smaller natural numbers.
05:48It cannot be evenly divided by any other positive integers
05:52without resulting in a remainder, fraction, or decimal.
05:56For instance, 13 is an example of a prime number.
06:0116. What is the first organ to develop in an embryo?
06:05Is it A. Brain, B. Heart, or C. Lungs?
06:13It's the heart.
06:1617. Now look at this image.
06:19What is this instrument called?
06:21Is it A. Trumpet, B. Bagpipes, or C. Saxophone?
06:28It's bagpipes, the national instrument of Scotland.
06:31As the name suggests, it has a pipe, called the blowstick, and a bag,
06:36along with two more essential parts, the chanter and the drones.
06:40The bag contains the air that the piper directs into it.
06:43This air is then compressed, which is crucial,
06:47as it enables the air to travel through the drone's enchanter to produce sound.
06:52Historically, bags were crafted from animal skins,
06:55but now there are also synthetic alternatives available.
06:5918. What is the brain's main energy nutrient?
07:02Is it A. Fat, B. Glucose, or C. Salt?
07:11Glucose.
07:11It's claimed that an adult person needs up to 7 ounces of glucose a day.
07:16So if you crave that chocolate bar, go for it.
07:2119. How old is Earth?
07:23A. 4.5 billion years.
07:26B. 6 billion years.
07:28C. 3 billion years.
07:32Yep, it's around 4.5 billion years old.
07:3720. Which ocean is the largest?
07:40Is it A. The Atlantic Ocean?
07:42B. The Indian Ocean?
07:45Or C. The Pacific Ocean?
07:49It's the Pacific Ocean.
07:51Not only is it the largest ocean, but it's also the deepest ocean on Earth.
07:5721. Who painted the Mona Lisa?
07:59Was it A. Vincent van Gogh?
08:02B. Claude Monet?
08:04Or C. Leonardo da Vinci?
08:09Sure thing. It's genius da Vinci.
08:12By the way, this painting may be unfinished.
08:14Leonardo started creating the Mona Lisa in the early 1500s, and he continued to perfect the artwork till as late
08:21as 1516 or 1517.
08:24In 1517, da Vinci had partial paralysis in his right hand, which may have made it difficult for him to
08:31add final details to the painting.
08:3522. What's the longest river in the world?
08:38A. The Amazon River?
08:39B. The Nile River?
08:41Or C. The Missouri River?
08:47Officially, it's the Nile.
08:48Still, some scientists argue that it's the Amazon, as its source was reconsidered some time ago.
08:5523. Which country is known as the Land of the Rising Sun?
08:59Is it A. China?
09:01B. Japan?
09:02Or C. Thailand?
09:07All of these countries are great, but it's Japan that is said to be the Land of the Rising Sun.
09:12Why?
09:13Just take a look at the map.
09:1524. What is the hardest natural substance on Earth?
09:19A. Gold?
09:20B. Diamond?
09:22C. Iron?
09:27Sure thing, it's the Diamond.
09:3025. On which continent is the Sahara Desert located?
09:34Is it A. Asia?
09:36B. Africa?
09:38Or C. Australia?
09:42No doubts here, the Sahara Desert is in Africa.
09:46Hey, if you thought it was the biggest one, you aren't right.
09:49It's the biggest hot desert, but the biggest deserts in the world are in Antarctica,
09:53Africa, and the Arctic.
09:5626. What is the most spoken language in the world?
09:59Is it A. English?
10:01Is it A. English?
10:01B. Mandarin Chinese?
10:03Or C. Spanish?
10:08Don't get tricked by China's impressive population.
10:11Mandarin Chinese takes the second place with 1.1 billion speakers.
10:16English takes first place with almost 1.5 billion speakers.
10:21Spanish only has 560 million speakers, and it's the fourth most spoken language in the world.
10:2827. Which fruit is known as the King of Fruits?
10:33A. Mango?
10:34B. Durian?
10:36Or C. Apple?
10:40So, if your answer is durian, you are team Southeast Asia.
10:44For that region, it's the King of Fruits.
10:47If your answer is mango, it means you are team India.
10:51And if your answer is apple, it might mean you just like apples.
10:5628. What shape is Earth?
10:59Is it A. Flat?
11:00B. Spherical?
11:02Or C. Round?
11:08Scientifically speaking, Earth is an oblate spheroid, meaning it's a tad flatter at the poles and rounder in the middle
11:15along the equator.
11:16Yes, the globe at school lied to you this whole time.
11:2129. What is the only planet in our solar system that rotates on its side?
11:26A. Venus?
11:28B. Uranus?
11:29Or C. Neptune?
11:3122. It's Uranus.
11:3530. In which year did the first email message get sent?
11:39A. 1971?
11:42B. 1969?
11:44Or C. 1980?
11:47It was over 50 years ago in 1971.
11:51Tomlinson, the guy who tested it, sent the first email to himself.
11:55And the message was, actually, he didn't remember what exactly he had sent.
12:00He thought it might have been something like, QWERTY U-E-UP?
12:04Just the top row of letters on a standard keyboard.
12:06Now, let's get going with the easy level.
12:09Can you guess the celestial body from this photo?
12:20With those famous rings, of course it's Saturn.
12:23What force keeps us grounded on Earth?
12:27Magnetism, gravity, or friction?
12:36It's gravity, the same force that put an apple on Newton's smart head.
12:40The moon is an asteroid, a satellite, or a planet.
12:52The moon is a natural satellite of Earth.
12:55Which star is closest to our planet?
12:58The North Star, Alpha Centauri, or the Sun?
13:07Well, it would be weird if it wasn't the Sun.
13:11Pluto is a dwarf planet.
13:13Is this true or false?
13:22The answer is true.
13:24Poor Pluto got kicked out of the main planet sequence,
13:27but joined its own family of dwarf planets in our solar system.
13:32What is the largest planet in our solar system?
13:34Jupiter, Pluto, or Earth?
13:43It's Jupiter, the gas giant.
13:47What planet is known as the red planet?
13:49Venus, Mars, or Jupiter?
13:59It's Mars.
14:00NASA's Curiosity rover showed us all its awesome red-orange desserts.
14:05Wait a minute.
14:06I mean, deserts.
14:08My bad.
14:10The Sun is a planet, a comet, or a star?
14:21The Sun is a star, which was kind of spoiled in question 4.
14:26What event marks the beginning of the universe according to science?
14:29The Great Fission, the Big Bang, or the Huge Boom?
14:38The answer is the Big Bang.
14:40Hence the name Big Bang Theory.
14:43Uh-huh.
14:45Black holes exist.
14:46True or false?
14:55The answer is true.
14:57We weren't sure before, but now we have even two photos of them.
15:02How many did you get?
15:03Write in the comments.
15:05Now let's move to the medium level.
15:08Guess the name of this scientist.
15:19This is a portrait of Albert Einstein.
15:23What can we call a group of stars forming a recognizable pattern?
15:28A galaxy, constellation, or a nebula?
15:35It's a constellation.
15:37Although, to be fair, galaxies and nebulas are also full of stars in different patterns.
15:43What is this phenomenon called?
15:45A lightning bolt, a shooting star, or an aurora borealis?
15:55This is a shooting star.
15:57Hey, make a wish!
15:59What is the smallest planet in our solar system?
16:02Venus, Mercury, or Mars?
16:12The answer is Mercury.
16:14Remember that Pluto is a dwarf planet.
16:17How many planets are in our solar system?
16:20Give yourself some time to count.
16:30We have eight major planets.
16:32Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
16:39Who is the first person to walk on the moon?
16:41Jeff Bezos, Neil Armstrong, or Elon Musk?
16:51Neil Armstrong, he's the only astronaut on the list.
16:55What is the name of our galaxy?
16:57The Milky Way, the Andromeda Galaxy, or the Steel Way?
17:07The Milky Way, like the chocolate bar.
17:09And the Andromeda Galaxy is our nearest neighbor.
17:13Man has already walked on Mars.
17:15Is this true or false?
17:25The answer is false.
17:27Only robots have been on Mars.
17:29But NASA believes that the first human Mars mission
17:32will take place in the 2030s.
17:35Saturn is a gas planet, Earth-like planet, or dwarf planet.
17:48Saturn is a gas giant, just like Jupiter.
17:51They're the biggest planets in our solar system.
17:54The Earth rotates on its own axis.
17:56True or false?
18:06It's true.
18:07The Earth rotates while it revolves around the Sun.
18:10Which is why we have days and nights.
18:13Well, that level was a bit tougher.
18:15Are you keeping up so far?
18:17Well, prepare for the hard level.
18:20What is this object called?
18:32This is actually a telescope.
18:34Specifically, the James Webb Telescope.
18:36It's based in space instead of on Earth.
18:40Which of these planets has the most moons?
18:43Saturn, the Earth, or Mars?
18:52While we have only one moon and Mars has two,
18:55Saturn has 146 moons.
18:58All because of its huge size and crazy gravity.
19:02Which planet is the farthest from the Sun?
19:05Uranus, Neptune, or Jupiter?
19:14It's Neptune.
19:15We mentioned it when counting the number of planets.
19:18It was also in order.
19:20How long does it take for light from the Sun to reach Earth?
19:248 minutes, 24 hours, or a second?
19:28Now, remember that light also travels at a certain speed.
19:32It's 8 minutes, 20 seconds.
19:34The speed of light is 186,000 miles per second.
19:38What is the hottest color for a star?
19:40Yellow, orange, or blue-white?
19:50The answer is, surprisingly, blue or blue-white.
19:54A bit counterintuitive, right?
19:57What is the true color of the Sun?
19:59White, yellow, or red?
20:09The answer is white.
20:11This makes sense because we know that white light,
20:13which comes from the Sun,
20:14breaks down in all the colors.
20:16So we only see the Sun as yellow
20:18because the atmosphere filters some of them.
20:22Earth has the most volcanoes in our solar system.
20:24True or false?
20:34It's false.
20:35Venus is the one with most of the volcanoes.
20:38It's actually the most toxic and crazy planet
20:40in our solar system.
20:42What is the name of the galaxy closest to the Milky Way?
20:46If you watch the video carefully,
20:48you'll get this one.
20:55It's the Andromeda galaxy.
20:57But while it's our closest neighbor,
20:59it's still 2.5 million light-years away.
21:03What is the coldest planet in our solar system?
21:06Uranus, Neptune, or Pluto?
21:15It's Uranus.
21:16Pluto's not a planet.
21:18And you think that it should be Neptune
21:20since it's farther away from the Sun,
21:21and average temperatures on Neptune are colder,
21:24minus 330 degrees Fahrenheit.
21:27But the lowest number,
21:28about minus 371 degrees Fahrenheit,
21:31was recorded on Uranus.
21:33So, this place can also be considered
21:36the coldest planet.
21:38Now, which planet has the most moons?
21:50Well, we mentioned this one before.
21:52It's Saturn, with an insane number of moons.
21:55Ooh, pat yourself on the shoulder for that one.
21:58Finally, let's tackle the impossible level.
22:01Good luck!
22:03What's the maximum speed of light in a vacuum?
22:06A million miles per second?
22:08186,000 miles per second?
22:10Or 42 miles per second?
22:12If you don't know, try to guess this one.
22:15It's 186,000 miles per second.
22:18And the distance that light covers
22:20in one year of traveling
22:21is called one light year.
22:24Now, on which planet can you jump the highest?
22:27The Earth, Venus, or Mercury?
22:36On Mercury!
22:37It's the smallest and lightest planet
22:39in our solar system,
22:40so the gravity there is very weak.
22:43What is the main component of the Sun?
22:46Oxygen, hydrogen, or nitrogen?
22:55The answer is hydrogen.
22:58It's what makes up most stars.
22:59And it's the most common element
23:01in the entire universe.
23:03What is the approximate age of the universe?
23:063 billion years,
23:0713.8 billion years,
23:09or 100 billion years?
23:16Well, it's 13.8 billion years.
23:18Meanwhile, our Sun is about
23:204.6 billion years old.
23:22Hey, I wasn't around then.
23:25Guess the name of this guy.
23:36This is a portrait of Isaac Newton.
23:40What is the hottest planet
23:42in our solar system?
23:43Venus, Mercury, or Earth?
23:52Well, you might think it's Mercury
23:53because it's closest to the Sun,
23:55but it's actually Venus.
23:57Like we said,
23:58it's the most toxic and volcanic planet
24:00we have around here.
24:01What type of star is the Sun classified as?
24:05A red giant,
24:06a white dwarf,
24:07or yellow dwarf?
24:14Even though the Sun's light is white,
24:17the Sun is a yellow dwarf,
24:19one of the colder star types.
24:21There's a black hole
24:22in the center of most big galaxies.
24:25True or false?
24:33That's actually true.
24:35While they don't suck in the entire galaxy,
24:37supermassive black holes
24:39usually hang out in the centers.
24:42What phenomenon causes the northern lights?
24:45Earth's magnetic field,
24:47cosmic rays,
24:47or black holes?
24:54It's the Earth's magnetic field.
24:57When Sun particles reach the Earth
24:58and interact with the atmosphere,
25:00they release bright energy,
25:02which causes beautiful colors in the sky.
25:05Time for some math.
25:07If the speed of light is 186,000 miles per second,
25:10and it reaches the Earth in 8 minutes,
25:12what is the distance between Earth and the Sun?
25:16Bonus points for calculating this in your mind.
25:23It's about 93 million miles.
25:26Now, did you crack the impossible level?
25:29Alright, let's see if you're smart enough to answer the final bonus question.
25:34If you were standing on the Moon,
25:36and the Earth was directly overhead in the lunar sky,
25:39how often would you see the Earth rise or set?
25:42Think about it.
25:48The answer is never.
25:50The Moon is tidally locked to Earth,
25:53which means that we can always see its one side,
25:56while the other side is always hiding away from us.
25:59Ooh, maybe it's shy.
26:00So, the Earth would stay nearly fixed
26:02in the lunar sky at all times.
26:04See you next time.
