Humanity has always been looking for answers, but there are still many big questions and problems we have not been able to answer yet. Scientists are striving every day to solve and prove some of these mysteries, but have only been able to come up with some interesting ideas, hypotheses and theories.Anyone who can solve and prove one of the following questions will probably win a Nobel Prize for their discoveries.#1 Why do we dream?#2 How can we eliminate cancer?#3 What happens when you die?#4 Are we alone in the universe?#5 Where does consciousness come from?#6 How many species are on Earth?#7 Is reality real?#8 How did life begin?#9 Why do we yawn?#10 Is time travel possible?#11 Is the universe truly infinite?#12 What’s at the bottom of the ocean?#13 Can we live for ever?#14 How do we beat bacteria?#15 What’s so weird about prime numbers?#16 Why do we sleep?#17 Why do we move forwards in time?#18 What came before the big bang?Thanks for reading!Source:10 Questions That Science Can't Answer YetThe 20 big questions in science10 mysteries that physics can't answer... yet

How do I know exactly what I want?

I went through this as well. I have seem many other people go through this. There can be multiple reasons, but I don’t think figuring them out will serve any purpose.Most of the things are interesting when they are new. Everybody knows this. However, if you do something for a really long time, then it will be interesting again! Once you realize the underlying philosophy of the field (and maybe want to add more to it), then it will seem really beautiful. You have to work a lot to reach that stage.What I feel now is that I never let the thing that interested me, kill me. If you are into Robotics, then do it so much that you either understand well but realize it’s not for you or you like the reality of doing Robotics so much that it becomes your passion. I always found something that I like but never did it enough to find out whether I really liked it or just liked the idea and abstract of it. Don’t do the same mistake. Spend at least good amount of time on something fairly interesting before discarding it.

I do not like the usage of "I wanted to know". What is a better alternative?

You have given the answer in  your own question! Another way of saying "I wanted to know', is 'Could someone please tell me...". A more sophisticated way is "Could someone enlighten me as to..."

Why do I want to know what my ex is up to and if he’s with anyone new if I’ve moved on from him and regret being with him in the first place?

In my mind this is a symptom of old habits. Whenever someone has been a part of our lives, it takes a while to break the habit of thinking about them daily. These thoughts lead you down a road that can only slow down your moving on. After I breakup, I suggest that you avoid social media, which just throws fuel on the fire. Comparison is the stealer of joy. These are natural thoughts to have, but try to push them away. Even if you discover that he is seeing someone new, this will just lead to more questions in your mind. You won’t know anymore than you did before the discovery.
