What if you fell into a black hole?

I'll color it with my color pencils.

No.

Boundary of the black hole is called event horizon.

Small black holes have stronger gravitational forces than large ones.

If you fell towards a small black hole.

The strong gravitational forces would stretch you.

Until you are torn apart, even before you cross the event horizon.

In case of a large black hole.

You would be able to enter it, unharmed.

Falling freely until you reach its center or point of singularity.

Here, you would get squashed and merge into it.

But your friend observing this from outside never actually sees you enter the black hole.

He just sees you fall in slow motion, freeze and then go dimmer.

Why?

Because our current laws of physics don't apply beyond the event horizon.

Making it impossible for us to see beyond.

Which is the best sleeping position?

Mine.

Alright.

Let's see.

Sleeping on our back allows our spine to rest in a neutral position.

Preventing neck and back pain.

Also, as the face is not pressed against the pillow.

It avoids over wrinkling.

However, this position is prone to more snoring.

Sleeping on our stomach prevents snoring but makes it difficult to maintain a neutral spine position.

It puts pressure on our joints and muscles, leading to numbness, neck and back pain, etc.

Sleeping on our side keeps the spine elongated and prevents neck and back pain.

Sleeping especially on the left side decreases acid reflux, improves blood circulation, digestion, etc.

However, side sleeping presses our face against the pillow and increases the chances of wrinkling.

Some people even curl up tightly while sleeping on one side.

This restricts breathing.

Now, since all positions have advantages and disadvantages, there is no best position.

But if sleeping in a specific position is causing problems.

You can switch to other positions for better results.

Are wisdom teeth still useful?

Obviously, Because wisdom teeth make us intelligent.

No.

There are 32 permanent teeth.

Out of which four wisdom teeth begin to grow a little late.

Now, when our ancient ancestors used to eat plant material and raw meat.

They required big strong jaws and wisdom teeth to chew their food.

As they learned to cook food, they no longer required those big jaws.

Hence, through evolution, the jaws started to get smaller and smaller.

But the wisdom teeth did not disappear through evolution.

They still exist.

But since they appear a little late

The remaining teeth usually take up the available space in the small jaw.

Leaving no room for the wisdom teeth.

Hence, they begin to grow at odd angles.

And push other teeth causing pain, swelling, tooth decay and even infection.

Hence, in such cases, wisdom teeth can prove to be harmful and not useful.

Is sleeping in contact lenses bad?

Not at all.

They help us see our dreams more clearly.

Oh.

Stop bluffing.

Contact lenses act like a sponge and absorb the moisture present in our eyes.

They even trap bacteria.

So, wearing them for too long.

Failing to clean them periodically and sleeping in them can cause excessive dryness.

And even eye infection.

In addition to this, unlike other parts of our body.

The cornea of our eye receives oxygen from the surrounding air and not from blood vessels.

Now, when we wear contact lenses during the day, it reduces the oxygen supply to the cornea.

But when we wear them while sleeping also, it further reduces the oxygen supply to the cornea.

Hence, to satisfy the oxygen need, tiny blood vessels grow in the cornea.

Thus causing blurred vision.
