Here is the list of Unanswered physics Questions
1. What is Dark Matter?
Cosmologists think that only about 5% of the universe is visible, made up of ordinary matter that forms billions of galaxies, stars, and planets, including us and everything else. So what exactly is this “dark matter” that emits no light and makes up roughly 25% of the universe?
2. What is Dark Energy?
The largest majority of the universe’s content (70%) is in the form of an unknown energy that has earned the name of “dark energy”.
What is this mysterious, gravity-repellent, dark energy that may suggest new physical laws beyond the standard model?
3. Is There a Multiverse?
Some astrophysicists think that the visible universe is but one among an infinite number of universes.
And, according to quantum physics, there’s only a finite number of possible particle arrangements, which are forced to repeat themselves in the multiverse over and over again.
That means that there are parallel universes that are exact copies of our realm (including you!), another that differs with only one particle configuration, or two… infinitely!
But we have yet to detect the presence of our parallel selves.
4. What Will be the Fate of Universes?
If the widely-accepted theory of the beginning of the universe (Big Bang) is yet to be proven, the ultimate fate of the universe may be a tougher nut to crack.
There are scenarios aplenty: try the Big Crunch, Big Freeze, Big Rip–many theories with the word “big” in them try to predict what destiny awaits our universe, with no definitive answer.
But hey, as far as us mortals are concerned, the human civilization (and any intelligent alien life!) will probably be long gone before the end of time.
But time doesn’t end, does it?
5. Why Time Appears to be Linear?
Time, as defined by Newton, remains a constant in physics. Newtonian mechanics organizes sequences of moments or events in chronological order.
But mounting scientific evidence suggests that time is cyclic and non-linear; in theory, it can be slowed down, stopped or reversed.
Why does time give the illusion of flowing as a linear and irreversible arrow?

6. How Consciousness Affects Reality?
If you want to put a quantum physicist or a philosopher of science on the spot, just bring up “The Measurement Problem”.
Simply put, a particle only takes a particular position if there’s an observer measuring it; that’s the ‘Measurement’ or ‘Observation’ Problem.
That means that a particle is all over the place until one decides to observe it in their own space-time. In other words, the very act of observation affects or creates, reality.
But how could a particle decide its position and momentum? Does this mean that objects, time, and locality are mere tools of our consciousness, projected out as “reality”?
7. Is There a Super-Force Behind the 4 Fundamental Forces?
There are four fundamental forces that govern the universe: gravity, electromagnetism, strong nuclear, and weak nuclear.
Maybe these universal forces operate in a similar way to Marvel’s Infinity Stones: each stone has its own purpose but their six powers can be harvested collectively using the Infinity Gauntlet.
Physicist think that the 4 forces would’ve resulted from a single and even more fundamental force and, because of that, may unite into one super-force.
