📝Text:

More than ten years ago, while taking the temperature of the universe, astronomers found something odd. They discovered that a patch of sky, spanning the width of 20 moons, was unusually cold.

📌True/False/Not given

1. Astronomers often find something odd on the sky.

Your answer 👇

📝Text:

The astronomers were measuring the thermal radiation that bathes the entire universe, a glowing relic of the big bang. To gaze at this cosmic microwave background, or CMB, is to glimpse the primordial1 universe, a time when it was less than 400,000 years old.

📝Text:

The CMB blankets the sky, and looks pretty much the same everywhere, existing at a feebly cold temperature of 2.725 kelvins - just a couple degrees warmer than absolute zero. But armed with the newly launched WMAP satellite, the astronomers had set out to probe temperature variations as tiny as one part in 100,000. Born from the quantum froth that was the universe a half-moment after the big bang, those random fluctuations help scientists understand what the cosmos is made of and how it all came to be.

📝Text:

And standing out amidst those fluctuations was a cold spot. Over the years, astronomers have come up with all sorts of ideas to explain it, ranging from instrumental error to parallel universes. But now, they're homing in on a prime suspect: an enormous cavern of emptiness called a cosmic supervoid, so big that it might be the largest structure in the universe.

✅ANSWERS:

1.Not given

The first paragraph tells us that astronomers have found something odd on the sky. But is it written anywhere that they do it often? No. That is why this information is not given in this text.

2.True

It is said in the second paragraph: "The astronomers were measuring the thermal radiation that bathes the entire universe, a glowing relic of the big bang. To gaze at this cosmic microwave background, or CMB ..."

3.False

It is said in the third paragraph: "The CMB blankets the sky, and looks pretty much the same everywhere, existing at a feebly cold temperature of 2.725 kelvins". Thus, CBM exists everywhere only at low temperatures.

4.True

It is said in the third paragraph: "....those random fluctuations help scientists understand what the cosmos is made of...".

5.Not given

The fourth paragraph tells us that cosmic supervoid is so big that it might be the largest structure in the universe. But is it? This information is not given in this text.
