70+ Questions that keep you up at night and don’t let you sleep on days end

By: Naveen B

As long as humans have been around, we’ve looked to the stars and wondered what life means and why we’re here.

And every now and then, a few mind blowing questions that keep you up at night and don’t let you sleep even for days end.

Can we really become immortal? What’s on the other side of the black hole?

There are many such great mysteries and unanswerable questions in this world. Often science answered as many riddles of the universe as it could.

In this article, in order to keep your mind wondering about the existence and beyond. Here are 70 of the most perplexing questions that keep you up at night about everything. Keep wondering.

70+ Questions that keep you up at night


1. Why do some people survive horrific accidents and others don’t?

Were certain individuals put on Earth for a specific purpose? Do these people change anything about our world by being here? If so, how?

Are these lucky few special in any way other than getting a second chance at life while other less fortunate souls meet their fate soon after they are born, never having gotten a fair chance at all?

If you think too much about it, for sure this question will keep you up at night for days.

2. Why do souls leave the body after death?

It’s still an unanswered question that no one can answer. However, it might be because of electromagnetic fields or because the person’s energy is depleted or because of some other unknown reason.

This is for sure one of the most mind boggling questions that keep you awake at night.

3. What are we living for if there are infinite universes?

Isn’t everything futile in the end? One popular answer is that maybe it’s because life itself serves a purpose, like evolving intelligent creatures who can marvel at beauty and appreciate the finer things in life -like music, poetry and art.

Maybe one day they’ll figure out their purpose, maybe they won’t-but they’ll keep trying anyway.

And while they’re trying they might as well enjoy themselves because what could be more futile than devoting your entire existence to accomplishing something you don’t even know whether you’re supposed to accomplish?

Have you ever wondered about this question and it didn’t let you sleep by thinking of it?

4. Is time travel possible?

This question about time travel can never be answered since traveling back in time would require breaking some of the fundamental laws of physics – namely laws like the speed of light is constant or the past can’t be changed.

But what if in the distant future science finds a way to make it possible.

Once we are able to time travel at the speed of light, so does our aging stop? Will we be able to live forever? These are some of the questions that keep you up at night.

5. Why are humans afraid of death and do we feel pain when we die?

Scientists found that most cells in our body die every day and get replaced by new ones. Each person has around 10 billion cells; therefore, there are always 10 billion new cells waiting to replace the old ones.

Isn’t it awesome? If they die every day, why don’t we feel pain when they die? Scientists say that when cells die naturally, their membranes ruptured spilling their contents into surrounding tissues.

It is because of these chemicals that make up a cell membrane (e.g., proteins) and leaked out into other tissues that cause inflammation and pain.

Even though cells may die everyday due to natural causes, people often fear death because they don’t know what will happen afterwards.

But, still, the thought of death itself won’t let you sleep once if we are obsessed with such mind boggling questions.

6. Why is there something rather than nothing?

It seems as if there should be nothing instead of something.

The question, why is there something rather than nothing? may never be able to be answered because in all probability, everything had a beginning and it could very well have been created by someone who came before us.

7. What if you will never get over someone hurt and cheated on you? Will you always be alone?

Many of us have been there in that situation. Constantly thinking all day and night about your love. It’s hard not to think about the loss of a loved one or about someone you love hurt you or left you.

But there are ways to cope with these things and sometimes people have the wrong idea. You could try to forget them and focus on yourself instead, but this is easier said than done and it takes time.

If they are still in your life and hurting you, then confronting them might help too.

There are also other options such as going out with friends or joining clubs where you meet new people so it doesn’t seem like every day is an unending stream of lonely thoughts.

8. Why are humans conscious, yet we don’t know what consciousness is or where it comes from?

This is such a mind boggling question which keeps you awake at night. What is it and where does it come from? These are very deep and hard questions to answer as we have no idea how consciousness or even thought works.

We don’t know what happens when we sleep, but despite being unable to do so, some scientists think we might be able to map out consciousness in our brain so we can get a better understanding of what goes on in there when our conscious mind falls asleep.

9. Does mankind need science and technology or spirituality too?

Some people say we should use spirituality while others say we should only rely on science and technology.

Those who believe in only using spiritualism believe man needs more than just science and technology to thrive.

Some may argue that society would crumble without both worlds, while others say that scientific progress would halt without those who believe in spiritualism.

But maybe mankind needs both the physical world (science) and the metaphysical world (spirituality) to thrive. But this question is worth seeking and realizing what suits you best.

10. Why is the world so beautiful and at the same time so miserable?

The world is often seen as both good and bad because everything in the world affects each other.

The beauty of nature juxtaposed against wars, hunger, poverty, etc. often makes people wonder why things are the way they are.

However there is no clear answer to this question because life isn’t black and white; things aren’t perfect nor terrible all the time – it changes based on context and perspective.

11. What is the meaning of life?

The meaning of life might not ever be found because it could very well depend on who an individual is when they are alive and what they are doing at that time in their lives. 

12. What happens after death?

We will likely never know what happens after death since it seems like our bodies just disappear or stop functioning once we die,

So far science has not been able to find any evidence of anything continuing after death. Even if it keeps us awake at night, we can ponder this question for days on end, yet we won’t come to any conclusion.
