Does time exist in a black hole?
Near a black hole, the slowing of time is extreme.
From the viewpoint of an observer outside the black hole, time stops.
Inside the black hole, the flow of time itself draws falling objects into the center of the black hole.
No force in the universe can stop this fall, any more than we can stop the flow of time..
Is time an illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.
Is the quantum realm real?
The quantum realm (or quantum parameter) in physics is the scale at which quantum mechanical effects become important when studied as an isolated system., respectively. Two classical examples are quantum tunneling and the double-slit experiment. …
Do atoms know they being observed?
In order for an observation (or measurement) to be made the object being observed must interact with the observing sensor. Particles are not sentient and do now”know” things. They don’t change their behavior. … Subatomic particles are too simple to “know” much at all.
Can observing something change it?
While the effects of observation are often negligible, the object still experiences a change. This effect can be found in many domains of physics, but can usually be reduced to insignificance by using different instruments or observation techniques.
Do things exist when not observed?
An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.
Is time the 4th Dimension?
But in the 106 years since Einstein, the prevailing view in physics has been that time serves as the fourth dimension of space, an arena represented mathematically as 4D Minkowski spacetime. …
Does the universe require an observer?
The universe of possibilities does not need a conscious observer to exist. The universe of actualities does. That’s because actualities require figure/ground contrast and that requires an observer to decide what is figure and what is ground.
What is outside the universe?
In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
What does the observer do?
In Minecraft, the observer watches the block in front of it and sends a redstone pulse when it detects a change. You can use an observer to build traps, farms, flying machines, bridges and so much more!
Who created God?
Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
Does the past still exist?
The past and future do not exist and are only concepts used to describe the real, isolated, and changing present. This conventional model presents a number of difficult philosophical problems, and seems difficult to reconcile with currently accepted scientific theories such as the theory of relativity.
Where does space end?
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
Are there other universes?
Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.
Does observation affect reality?
Summary: One of the most bizarre premises of quantum theory, which has long fascinated philosophers and physicists alike, states that by the very act of watching, the observer affects the observed reality.
What counts as an observer in quantum mechanics?
Observer is a special person (or a system that contains such person) which does not obey the usual laws of quantum mechanics.
What causes the observer effect?
That experiment is one example of the observer effect. Anytime measuring (or observing) something causes a change in the original state, this is called the observer effect. … The mere presence of a thermometer will either raise or lower the heat of whatever you are trying to measure.
What is an observer in control theory?
In control theory, a state observer is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system. … If a system is observable, it is possible to fully reconstruct the system state from its output measurements using the state observer.
