# How many universes are there?

In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

## How do you answer physics questions?

1. Focus on the Problem. Establish a clear mental image of the problem. A.
2. Describe the Physics. Refine and quantify your mental image of the problem. A.
3. Plan a Solution. Turn the concepts into math. A.
4. Execute the Plan. This is the easiest step – it’s just the algebra/calculus/etc. A.
5. Evaluate the Answer. Be skeptical.

## Does physics answer why or how?

Physics is a description of how the universe behaves. It does not say why.

## What is physic answer?

What is physics? Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity.

## Why can’t science answer all questions?

Like all disciplines, it is limited by the unique tools at its disposal: in the case of science, it is the tools of mathematics and empirical observation. The tools of science are quantitative; they are therefore limited in the possible answers they might give to quantitative answers.

## Is physics easy or hard?

Students and researchers alike have long understood that physics is challenging. But only now have scientists managed to prove it. It turns out that one of the most common goals in physics—finding an equation that describes how a system changes over time—is defined as “hard” by computer theory.

## What is the hardest question in physics?

1. What is matter made of?
2. Why is gravity so weird?
3. Why does time seem to flow only in one direction?
4. Where did all the antimatter go?
5. What happens in the gray zone between solid and liquid?
6. Can we find a unified theory of physics?
7. How did life evolve from nonliving matter?

## What is the hardest question in science?

• Why is the sky blue?
• Why does the moon appear in the daytime?
• How much does the sky weigh?
• How much does the Earth weigh?
• How do airplanes stay in the air?
• Why is water wet?
• What makes a rainbow?
• Why don’t birds get electrocuted when they land on an electric wire?

## What is the hardest physics equation?

Yet only one set of equations is considered so mathematically challenging that it’s been chosen as one of seven “Millennium Prize Problems” endowed by the Clay Mathematics Institute with a \$1 million reward: the Navier-Stokes equations, which describe how fluids flow.

## What is the hardest theory to understand?

• The Black Swan Theory.
• The Potato Paradox.
• Simulacra and Simulations.
• The Dichotomy Paradox.
• Vasiliev Equations.
• Maxwell’s Equations.
• Gödel’s Incompleteness Theorem.
• The Theory of General Relativity.

## What is the main purpose of physics?

Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.

## Why is physics so amazing?

Physics helps us to organize the universe. It deals with fundamentals, and helps us to see the connections between seemly disparate phenomena. Physics gives us powerful tools to help us to express our creativity, to see the world in new ways and then to change it.

## 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 question does not have an answer?

rhetorical question Add to list Share. When you ask a rhetorical question, you don’t really expect an answer.

## What can science not do?

• Science doesn’t make moral judgments.
• Science doesn’t make aesthetic judgments.
• Science doesn’t tell you how to use scientific knowledge.
• Science doesn’t draw conclusions about supernatural explanations.

## Is physics harder than math?

Physics might be more challenging because of the theoretical concepts, the mathematical calculations, laboratory experiments and even the need to write lab reports.

## Is physics harder than biology?

Beginning university students in the sciences usually consider biology to be much easier than physics or chemistry. From their experience in high school, physics has math and formulae that must be understood to be applied correctly, but the study of biology relies mainly on memorization.

## What is the hardest subject?

The hardest degree subjects are Chemistry, Medicine, Architecture, Physics, Biomedical Science, Law, Neuroscience, Fine Arts, Electrical Engineering, Chemical Engineering, Economics, Education, Computer Science and Philosophy.

## What is the biggest unanswered question?

• Are we alone in the universe? –
• Will there ever be a cure for cancer? –
• Does God exist? –
• How big is space? –

## What is the world’s hardest question?

The question, “What do we know and how do we know it?” occupies the mind of the epistemologist. The prevailing theory of truth, at least among the public and certainly among scientists, is the correspondence theory, which states that truth corresponds with facts and reality.

## What is the most beautiful equation in physics?

The formula most commonly rated as beautiful in the study, in both the initial survey and the brain scan, was Euler’s equation, eiπ+ 1 = 0.

## What science is hard?

Definition of hard science : a science (such as chemistry, physics, or astronomy) that deals with things that can be observed and measured.

## What is easier chemistry physics or biology?

One might perceive Biology as the most challenging subject, while another one might consider Physics as the hardest A-Level course. All three A-Level courses, Biology, Chemistry, and Physics, consist of relatively easy or tough sections, which again entirely depend on a specific individual’s enthusiasm.

## 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?

## Is physics harder than 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.
