    destiny
In summary, the conversation discussed the concept of predicting the future based on the laws of physics and whether destiny exists in the universe. It was mentioned that due to chaos theory and the uncertainty principle, it is impossible to predict the future with complete accuracy. The existence of hidden variables and the potential for our current understanding of laws to be incomplete was also brought up. It was concluded that while we can make fairly accurate predictions, true randomness and non-determinism are present in our universe.

I know that the world is made of atoms and energy, so humans. If we have a supercomputer that know the velocities, masses and other physical measurements of all the atoms at a specific time, then we can predict what will going to happen in the next second using laws of physics. Is that mean we can predict the future and there is destiny?

First of all, due to chaos theory unless you know the EXACT position and velocity of EVERY particle in the universe your prediction will break down. That is an impossible feat in and of itself. Secondly, the Uncertainty Principle only allows for simultaneous knowledge of a particle's position and velocity up to a certain point. This induces non-determinism into our universe. Maybe, however, quantum mechanics is an incomplete theory. But, in the current understanding of the physical world the short answer to your question is no.

Its called predicting the weather and/or you can read daily horoscopes which aren't always right just like the weather. Destiny is what you make it.

It means that given a set of initial conditions, and assuming they are sufficient to describe a system, one can make predictions about that system which will be fairly accurate.

However, like silmaril89 said, chaos is a tricky devil, and there are some "hidden variables" which can cause a system to diverge rather unexpectedly even though the initial conditions are similar (or even the same!).

Byron, the short answer is that Science has never observed anything that could be described as "Destiny". Not like most people talk about it. It IS true that we can predict events with amazing accuracy, but Destiny implies that you have no choice in the matter.

It is the destiny of a ball to fall to the floor when I let go of it.

Thanks all
Are the chaos and hidden variables due to the imperfection of our physics laws or there is true randomness is our universe?
I just wonder if there is no true randomness in our universe and all the uncertainties are due to our incomplete understanding of the laws governing the behavior of all things, can we predict what will happen in the next second, for example in a frictional universe that contains only 2 atoms?

You can only predict it to a certain degree because of the uncertaintity principle.

As far as we can tell (and we have checked quite a bit), HUP is a fact. Thus, the universe is non-determisitic. That means it is impossible to predict the future better than a certain level of accuracy (which will be determined by the number of particles in the system). Error increases exponentially with more particles.

1. What is destiny?

Destiny is a concept that refers to the predetermined course of events in someone's life. It is often seen as a force or power that guides and controls the path of an individual's life.

2. Can we change our destiny?

This is a highly debated question. Some people believe that our destiny is predetermined and cannot be changed, while others believe that we have the power to alter our path through our choices and actions.

3. Is there any scientific evidence for destiny?

There is currently no scientific evidence that supports the idea of destiny. It is considered a philosophical and spiritual concept rather than a scientific one.

4. Can we predict the future?

The ability to predict the future is a controversial topic. While some people claim to have psychic abilities or use tools like astrology or tarot to make predictions, there is no scientific evidence to support the accuracy of these methods.

5. Are there any factors that can influence our destiny?

Some people believe that our destiny is influenced by external factors such as genetics, environment, and societal norms. Others believe that our choices and actions play a significant role in shaping our destiny.
