Size of universe: The diameter of the observable universe is about 93 billion light-years, but what is the size of the whole universe? Baryon asymmetry: Why is there far more matter than antimatter in the observable universe? (This may be solved due to the apparent asymmetry in neutrino-antineutrino oscillations.)

Which is the hardest theory in physics?
Quantum mechanics is deemed the hardest part of physics. Systems with quantum behavior don’t follow the rules that we are used to, they are hard to see and hard to “feel”, can have controversial features, exist in several different states at the same time – and even change depending on whether they are observed or not.
What is the hardest question in science?

- Why does the moon appear in the daytime?
- How much does the sky weigh?

- What makes a rainbow?
- Why don’t birds get electrocuted when they land on an electric wire?
Does time really exist?
Does time exist? The answer to this question may seem obvious: of course it does! Just look at a calendar or a clock. But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously.
What are the 10 questions science can t answer?
What happens to us after we die? How did so much life appear on our planet when others seem devoid of any species at all? Who, if anyone, pulls the strings of our universe? Is it some all-powerful god in control or are there physical and mathematical principles driving the engine of our existence?
What are some unanswerable questions?
- Why does anything exist?
- How was the universe formed?
- Why was it created, and why like this?
- What existed before the universe?
What are the most unanswered questions?
- Are we alone in the universe? –
- Will there ever be a cure for cancer? –
- Does God exist? –
- How big is space? –
What are the biggest questions in physics?
- 1 – The origin of the Universe:
- 2 – The nature of Dark Matter:
- 3 – The nature of Dark Energy:
- 4 – The formation of structures in the Universe:
- 5 – The validity of General Relativity:
- 6 – The validity of Quantum Mechanics:
Is antimatter a real thing?
Although it may sound like something out of science fiction, antimatter is real. Antimatter was created along with matter after the Big Bang. But antimatter is rare in today’s universe, and scientists aren’t sure why.
What are the greatest mysteries of physics?
- QUANTUM SCIENCE.
- TIME AND SPACE.
- MISSING DIMENSIONS. Why does space have three dimensions?
- CASIMIR EFFECT. Can we get energy from nothing?
- LIQUID CHAOS. What is glass?
- FIELD OF ICE. Why is ice slippery?
- PARTICLE PHYSICS. How long does a proton live?
- SOLAR SYSTEM. Is the universe infinite or just very big?
What is harder physics or chemistry?
Physics is considered comparatively harder than chemistry and various other disciplines such as psychology, geology, biology, astronomy, computer science, and biochemistry. It is deemed difficult compared to other fields because the variety of abstract concepts and the level of maths in physics is incomparable.
Where does antimatter go?
This created a small surplus of matter, and as the universe cooled, all the antimatter was destroyed, or annihilated, by an equal amount of matter, leaving a tiny surplus of matter. And it is this surplus that makes up everything we see in the universe today.
Why is physics so hard?
Answer: Physics demands problem-solving skills that can be developed only with practice. It also involves theoretical concepts, mathematical calculations and laboratory experiments that adds to the challenging concepts.
What are the 10 hardest questions in the world?
- Does true love exist? This is one of the most controversial and frequently asked life questions.
- Is there life after death?
- Should abortion be allowed?
- What is the purpose of life?
- Why is there hatred in the world?
- Does he or she love me?
What’s the hardest question on earth?
Science is based on the correspondence theory of truth, which claims that truth corresponds with facts and reality. Various philosophers have put forth substantive challenges to the truth claims made by science.
What are 3 good scientific questions?
- 1 What is the universe made of?
- 2 How did life begin?
- 3 Are we alone in the universe?
- 4 What makes us human?
- 5 What is consciousness?
- 6 Why do we dream?
- 7 Why is there stuff?
- 8 Are there other universes?
Who created time?
The Egyptians broke the period from sunrise to sunset into twelve equal parts, giving us the forerunner of today’s hours. As a result, the Egyptian hour was not a constant length of time, as is the case today; rather, as one-twelfth of the daylight period, it varied with length of the day, and hence with the seasons.
Is time the 4th dimension?
Physics > Space and Time According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.
Can time be stopped?
The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein’s two Relativity Theories.
What are 5 scientific questions?

- How did life begin?
- Are we alone in the universe?

What are big questions?
Definition of Big Question (BQ) A big, or essential, question (BQ) is open-ended, taps into the heart of the discipline, provides an opportunity for integration and connection to personal/social/professional issues, and addresses the question of “what can I do with this learning?”
Is the universe infinite?
There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
What question has no answer?
A rhetorical question is one for which the questioner does not expect a direct answer: in many cases it may be intended to start a discourse, or as a means of displaying or emphasize the speaker’s or author’s opinion on a topic.
