LIFE

 

LIFE

 

 

 

1. HOW DID LIFE BEGIN?

Ans: Scientific experiments in the 1950 s showed how lightning flashes might create amino acids, the basic chemicals of life, from the waters and gases of the early Earth. But no one knows how these chemicals joined up to become “self replicating -that is, able to make copies of themselves. This is the key to life, which remains a mystery. However, the first life forms were probably tiny bacteria called Archebacteria, which thrive in very hot, chemically rich places.

 

 

2. WHAT IS LIFE MADE OF?

Ans: Life is based on complex compounds of the element carbon, known as organic chemicals. Carbon compounds called amino acids link up to form proteins, and proteins form the complex chemicals that build and maintain living cells.

 

 

3. WHERE DID THE MATERIALS OF LIFE COME FROM?

Ans: It used to be thought that organic chemicals all originated on Earth, but traces of all kinds of organic chemicals
have be on detected in giant molecular clouds, including formaldehyde, alcohol, and also acetaldehyde, one of the
components of amino acids.

 

 

4. WHERE DID LIFE COME FROM?

Ans: Most scientists think life on Earth began on Earth,in the oceans or in volcanic pools. But some think the Earth was seeded by micro- organisms from space.

 

 

5. ARE THERE ANY OTHER PLANETS LIKE EARTH?

Ans: There is no other planet like Earth anywhere in the solar system. Recently, though. planets have been detected circling other stars in neighbouring galaxies. But they are too far away for us to know anything about them at all.

 

 

6. WHAT DOES AN ALIEN LOOK LIKE?

Ans: At the moment, the only aliens we are likely to encounter are very, very small and look like viruses.

 

 

7. HOW ARE WE LOOKING FOR EXTRA-TERRESTRIAL LIFE?

Ans: Since possible fossils of microscopic life were found in Martian meteorite found on Earth in 1996, scientists have hunted for other signs of organisms in rocks from space. Robotic probes are currently searching for signs of life on Mars.

 

 

8. IS THERE LIFE ON OTHER PLANETS?

Ans: Organic chemicals are widespread, and the chances are that in such a large universe there are many planets, like Earth, suitable for nurturing life. But no one knows if life arose on Earth by a fantastic and unique chain of chance events, or whether it is fairly likely to happen given the right conditions.

 

 

9. WHY IS THE UNIVERSE LIKE IT IS?

Ans: The amazing chance that life exists on Earth has made some scientists wonder if only a universe like ours could contain intelligent life. This is called the weak anthropic principle. Some go further and say that the universe is constructed in such a way that intelligent life must develop at some stage. This is called the strong anthropic principle.

 

 

10. WHAT IS DNA?

Ans: Deoxyribonucleic acid, the most remarkable chemical in the universe, is the tiny molecule on which all life is based. It is shaped a bit like a long rope ladder, with two strands twisted together in a spiral, inked by “rungs” of four different chemical bases. The order of these bases is a chemical code that provides all the instructions needed for life.

 

 

11. WHAT IS SETI ?

Ans:  SETI  is the Search for Extra-Terrestrial Intelligence project, designed to continually scan radio signals from space and pick up any signs of intelligence. lt looks for signals that have a pattern, but are not completely regular, like those from pulsating stars.

History Of The Universe

by Leave a Comment

HISTORY OF THE UNIVERSE

 

 

 

 

 

 

 

1. WHAT WAS THE UNIVERSE LIKE AT THE BEGINNING?

Ans: The early universe was very small, but it contained all the matter and energy in the universe today. It was a dense and chaotic soup of tiny particles and forces, and instead of the four forces scientists know today, there was just one super force. But this original universe lasted only a split second. After just three trillion of a trillionth of a trillionth of a second, the super force split up into separate forces.

 

 

2. WHAT WAS THERE BEFORE THE UNIVERSE?

Ans: No one knows. Some people think there was an unimaginable ocean beyond space and time of potential universes continually bursting into life, or failing Ours succeeded.

 

 

3. WHAT WAS THE BIG BANG?

Ans: In the beginning, all the universe was squeezed into an unimaginably small, hot, dense ball. The Big Bang was when this suddenly began to swell explosively, allowing first energy and matter, then atoms, gas clouds and galaxies
to form. The universe has been swelling ever since.

 

 

4. CAN WE SEE THE BIG BANG?

Ans: Astronomers can see the galaxies hurtling away in all directions. They can also see the afterglow low level microwave radiation coming at us from all over the sky, called the background radiation.

 

 

5. HOW DO WE KNOW WHAT IT WAS LIKE?

Ans: We know partly by mathematical calculations, and partly by experiments in huge machines called colliders and
particle accelerators. These recreate conditions in the early universe by using magnets to accelerate particles to astonishing speeds in a tunnel, and then crash them together.

 

 

6. WHAT IS INFLATION?

Ans: Inflation was when dramatic expansion and cooling took place after the first second or so in the life of the universe, when spaces welled up and cooled enormously.

 

 

7. HOW DO WE KNOW THE UNIVERSE IS GETTING BIGGER?

Ans: We can tell the universe is getting bigger because every galaxy is speeding away from us. Yet the galaxies themselves are not moving-the space in between them is stretching.

 

 

8. HOW DID THE FIRST GALAXIES AND STARS FORM?

Ans: They formed from lumps of clouds of hydrogen and helium, either as clumps broke up into smaller, more concentrated clumps, or as concentrations within the clumps drew together.

 

 

9. HOW OLD IS THE UNIVERSE?

Ans: We know that the universe is getting bigger at a certain rate by observing how fast distant galaxies are moving. By working out how long it took everything to expand to where it is now, we can wind the clock back to the time when
the universe was very, very small indeed. This suggests that the universe is between 10 and 20 billion years old. However, studies of globular clusters suggest some stars in our galaxy may be older than this.

GALAXIES

galaxy

 

 

 

 

1. WHAT IS A GALAXY?

Ans: Our Sun is just one of a massive collection of 200 billion stars arranged in a shape like a fried egg, 100,000 light-
years across. This collection is called the Galaxy, because we see it in the band of stars across the night sky called the Milky Way. (Galaxy comes from the Greek for milky.) But earlier this century it was realized that the Galaxy is just one of billions of similar giant star groups scattered throughout space, which we also call galaxies. The nearest is the Andromeda galaxy.

 

 

2. WHAT ARE STAR CLUSTERS?

Ans: Stars are rarely entirely alone within a galaxy. Most are concentrated in groups called clusters. Globular clusters are big and round. Galactic clusters are small and formless.

 

 

3. HOW MANY GALAXIES ARE THERE?

Ans: There are currently estimated to be about 125 billion galaxies in the universe – there may be many, many more than this.

 

 

4. WHAT IS THE MILKY WAY?

Ans: The Milky Way is a pale, blotchy, white band that stretches right across the night sky. From Earth you only get an edge-on view of the Milky Way. A powerful telescope shows it is made up of millions of stars.

 

 

5. WHAT ARE DOUBLE STARS?

Ans: Our Sun is alone in space, but many stars have one or more nearby companions. Double stars are called binaries.

 

 

7. WHAT IS A SPIRAL GALAXIES?

Ans: A spiral galaxies are  galaxies that has spiralling arms of stars like a gigantic Catherine wheel. They trail because the galaxy is rotating Our Galaxy is a spiral galaxy.

 

 

8. WHAT IS THE BIGGEST THING IN THE UNIVERSE?

Ans: The biggest structure in the universe is the Great Wall -a great sheet of galaxies 500 million light-years long and 16 million light-years thick.

 

 

9. WHERE IS THE EARTH?

Ans: The Earth is just over half way out along one of the spiral arms of the Galaxy, about 30,000 light-years from the center.

 

 

10. WHAT EXACTLY ARE NEBULAE?

Ans: Nebulae are giant clouds of gas and dust spread throughout the galaxies. Some of them we see through telescopes because they shine faintly as they reflect star With others, called dark nebulae, we see only inky black patches hiding the stars behind. This is where stars are born . A few, called glowing nebulae, glow faintly of their own a as the gas within them is heated by nearby stars.

MATTER

 

1. WHAT IS THE UNIVERSE MADE OF?

Ans: The stars and clouds in space are made almost 100% of hydrogen and helium, the lightest and simplest elements of all. All the other elements are relatively rare. But some, such as carbon, oxygen,silicon, nitrogen and iron can form important concentrations. This happens in the few rocky planets like Earth, where iron, oxygen and magnesium are the most common elements. Carbon, a scarcer element, is the one on which all
life forms are based.

 

 

2. WHAT WAS THE FIRST ELEMENT?

Ans: The first element to form was deuterium – a heavy form of hydrogen. It formed within I.5 minutes of the dawn of the universe.

 

 

3. HOW WAS IRON MADE?

Ans: Iron was forged in the heart of super giant stars near the end of their lives, when the immense pressures there forced carbon atoms together.

 

 

4. WHAT IS ANTI-MATTER?

Ans: Anti-matter is the mirror image of ordinary matter. If matter and anti-matter meet,they annihilate each other.
Fortunately, there no anti-matter on Earth.

 

 

5. WHAT HOLDS EVERYTHING TOGETHER?

Ans: Everything in the universe is held together by four invisible forces. Two of them gravity and electromagnetism-are familiar in everyday life. The other two – the strong and weak nuclear forces are unfamiliar because they operate only inside the invisibly small nucleus of the atom, holding it all together.

 

 

6. HOW WERE ATOMS MADE?

Ans: Atoms of hydrogen and helium were made in the early days of the universe when quarks in the matter soup joined
together. All other atoms were made as atoms were fused together by the intense heat and pressure inside stars.

 

 

7. WHAT ARE PARTICLES?

Ans: Particles are the basic units of matter that make up everyday objects. There are hundreds of kinds of particles, but all apart from the atom and molecule are too small to see, even with the most powerful microscope.

 

 

8. WHAT IS THE SMALLEST KNOWN PARTICLE?

Ans: The smallest particle inside the nucleus is the quark. It is less than 1020 m across, which means a line of ten billion billion of them would be less than a metre long.

Gravity and Black Hole

by Leave a Comment

GRAVITY AND BLACK HOLE

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. WHAT IS A BLACK HOLE?

Ans: If a small star is very dense, it may begin to shrink under the pull of its own gravity. As it shrinks, it becomes denser and denser and its gravity becomes more and more powerful-until it shrinks to a single tiny point of infinite density
called singularity. The gravitational pull of a Singularity is so immense that it pulls space into a  “hole” like a funnel. This is the black hole, which sucks in everything that comes near it with its huge gravitational force- including light, which is
why it is a “black” hole.

 

 

2. WHAT IS GRAVITY?

Ans: Gravity is the mutual attraction between every single bit of matter in the universe. The more matter there is, and the closer it is, the stronger the attraction. A big, dense planet pulls much more than a small one, or one that is far away. The Sun is so big, it makes its pull felt over millions of kilometres of space. The Earth is smaller, but big enough to keep the Moon circling around it. The weight of an object is simply how hard gravity is pulling on it.

 

 

3. HOW STRONG IS A PLANET’S GRAVITY?

Ans: The more massive the planet that is the more matter it contains the more powerful its gravity. Astronauts on the Moon could jump up high in heavy spacesuits,because the Moon is much smaller than the Earth and its gravity is weaker.

 

 

4. HOW BIG IS A BLACK HOLE?

Ans: The singularity at the heart of a black hole is infinitely small. The size of the hole around it depends on how
much matter went into forming it. The black hole at the heart of our galaxy maybe about the size of the solar system.

 

 

5. WHAT ARE ORBITS?

Ans: In space, many objects such as planets and moons continually circle around larger objects.An orbit is the path they take. This is usually elliptical rather than perfectly circular in shape.

 

 

6. WHAT HAPPENS INSIDE A BLACK HOLE?

Ans: Nothing that goes into a black hole comes out, and there is a point of no return called the event horizon. If you went
beyond this you would be “spaghettified” – stretched long and thin until you were torn apart by the immense gravity.

 

 

7. HOW MANY BLACK HOLES ARE THERE?

Ans: No one really knows. Because they trap light, they are hard to see. But there may be as many as 100 million black holes in the Milky Way.

 

 

8. WHAT DID NEWTON DISCOVER?

Ans: The discoveries of Sir Isaac Newton (1642-1727) include the three fundamental laws of motion. He also discovered the force called gravity, which holds the Moon in orbit around the Earth, and the planets in orbit around the Sun.
