What is Cosmological Redshift?

• displacement of the spectrum of an astronomical object toward longer wavelengths.

• displacement of the spectrum of an astronomical object toward more concentrated wavelengths.

• both (a) and (b)

• none of the above

What will happen to your body if you move at the speed of light for 5 seconds?

• you will move suddenly very fast and other than you no one would be able to see you

• you will suddenly see your destination and you will not realize that 5 seconds have passed

• your body will become a photon hence your brain won't be functioning and you will remember nothing

• you will see everything other than you moving as slow

Answer explanation

If you suddenly moved in the speed of light, you will probably die as a photon hits the object in front of it, that is why scientists suggest of a more feasible way of fast travel in space when our technology gets like that, this method is known as "Warp Drive"

A helicopter is flying at constant speed with a uniform flexible rope hanging from it in Titan(Saturn's biggest moon). What shape does the rope make? (air resistance is NOT negligible) [A hint is given in the picture of the question]

• 
• 
• 
• 

Answer explanation

When the helicopter moves in a direction, air resistance(friction) is also there, this makes a tension along the rope, since the rope has equal pressure maintained all around and no external air pressure is coming since Titan's atmosphere is similiar to of Earth, the rope will be almost flying diagonally to the helicopter

Why is Jupiter important to the Earth?

• It keeps the earth's orbit in stability

• It maintains a mass balance of planets and sun in the solar system

• It attracts a lot of potential asteroids which were going to hit the earth

• It does not protect the Earth

Answer explanation

The Sun has 99.98% of the mass of the Solar System, Jupiter is the second most heaviest object with 0.5% of the entire mass of solar system, it actually protects Earth from getting hit by thousands of Asteroids coming from the Kuiper belt which is beyond Neptune, without Jupiter we won't be here today

The Big Bang was a big explosion which we theorize to be the beginning of the universe, it happened around ___ billion years?

Answer explanation

It is not yet clear tat the universe is 13.8 billion years old or 13.7, what is clear is that we humans currently are not capable of knowing this, some scientists believe in the big bang theory, some in the inflation theory and some in other theories but no theory to this day has been confirmed

On 5 November 2013, ISRO launched Mangalyaan 1 and proved the world that India can also be a member of the elite group, which rocket was used in the launching of this legendary mission? [Hint is given in the question's picture]

• SLV-3

• PSLV

• GSLV Fat Boy

• GSLV Mark-III

Answer explanation

The Chandrayaan 1 was successfully launched by the PSLV rocket, but sadly it did not have enough fuel to launch the payload required to get to mars, hence ISRO tried to make another rocket GSLV Fat boy to do the job, but sadly it failed and was not constructed within time, despite this and other companies like NASA making fun of India, we were able to use a technique known as gravitational slingshot to get the payload of Mangalyaan to Mars by using PSLV!

Chandrayaan - 1 made what discovery?

• It founded water on Moon

• It founded Air on moon

• It founded nothing on moon

• It founded aliens on moon

Answer explanation

Chandrayaan 1 made the groundbreaking discovery that there was water on the moon! In continuation Chandrayaan 2 was launched which was supposed to bring a sample of the water but sadly the rover could not do soft land and the mission was not completely successful though it was not a failure either

Which was the final mission of Kalpana Chawla and why?

• STS-108 and she never again rode any shuttle and this was her last mission

• STS-107(STS-107 the 28th and final flight of Space Shuttle Columbia. An reentry into the atmosphere on 1 February killed all seven crew members and disintegrated Columbia

• STS-109[due to some reason the space shuttle actually burned in the air while re entering the earth in which she died]

• STS-110, after this she quit her carrer

Which of these is an real image and not artificially designed?

• 
• 
• 
• 

Answer explanation

The question was that which of these is a real image not which one is the image of the black hole, we cannot get the exact image of the black hole since no light can escape from its gravity but its accretion disc can be seen

This star's explosion(Supernovae) will be seen in 2022. [Hint: It is the arm joint of the orion constellation]

• R136a1

• Stephenson 2-18

• Betelgeuse

• VY Canis-Majoris

Answer explanation

The surprising fact here is that other than R136a1, all other stars are speculated to have already died, but we will be able to see Betelgeuse die in 2022 and it will shine in the sky for about 9 months
