What caused the cause of the Big Bang?
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
How does matter exist if it Cannot be created?
Matter is continuously destroyed in stellar interiors which are undergoing nucleosynthesis (sort of like continual hydrogen bombs). In that process some matter is converted into radiation, energetic photons and neutrinos. Matter is also destroyed entirely within black holes, as far as we know.
Did Einstein say energy Cannot be destroyed?
“Energy cannot be created or destroyed; it can only be changed from one form to another.” (Albert Einstein).
What does it mean when they say matter Cannot be created or destroyed?
Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
Where did the Big Bang come from?
Many cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere. What isn’t clear, however, is why this cosmic energy persisted long enough to drive the Big Bang.
Is it possible to create energy from nothing?
To answer your question about the “creation of energy”: it is sufficient to say that in the quantum mechanics realm, it is perfectly allowed to “borrow” energy from nothing. As long as the time when the energy is borrowed does not violate the uncertainty principle.
How much energy does the universe have?
If you take that the total variance of energy of the universe to be Δ E = 0, then, according to this principle, you can have Δ t → ∞ and then, the universe can exist for an indefinite amount of time. The stated fact is that the total amount of energy of the universe is exactly 0.
Could the universe have spawned from quantum fluctuations?
These particles are also called “virtual particles” as they do not exist freely and cannot be measured directly. Thus, according to Hawking, the Universe could have spawned from such a quantum fluctuation as long as the total energy borrowed is 0.
