What equation describes the universe?
Friedmann equation
The Friedmann equation describes it all. Although Friedmann’s life was short, his influence cannot be overstated. He was the first to derive the General Relativity solution that describes our Universe: an expanding Universe filled with matter.
Is there a mathematical equation for the universe?
we associate electromagnetism, Newtonian gravitation, special relativity and quantum physics. The formula toc=h/moc expresses the electro-gravitational field bound to M2VP . Protons ( M2VP ) represent the stable particles of matter of the expanding universe.
What is the equation for space?
1.50 × 1010m-3/kg/s2, with its subject equation as S= ﯼM/r2. S is the space fabric….Space equations.

Which universe is described by the model of the universe for K 0?
For k > 0 the density is high enough that the gravitational attraction will eventually stop the expansion and it will collapse backward to a “big crunch”. This kind of universe is described as being a closed universe, or a gravitationally bound universe.
Do you think that the universe will exist without mathematics?
The Universe is out there, waiting for you to discover it. Many such mathematical constructs exist to explore, but without a physical Universe to compare it to, we’re unlikely to learn anything meaningful about our Universe. …
What is the hardest physics question?
The 7 Biggest Unanswered Questions in Physics
- What is matter made of?
- Why is gravity so weird?
- Why does time seem to flow only in one direction?
- Where did all the antimatter go?
- What happens in the gray zone between solid and liquid?
- Can we find a unified theory of physics?
- How did life evolve from nonliving matter?
Can we save the universe without the cosmological constant?
In 1922, just three years after the eclipse confirmation, Friedmann found an elegant way to save the Universe while simultaneously doing away with the cosmological constant: don’t assume that it’s static. Instead, Friedmann argued, assume that it is as we observe it, full of matter and radiation, and allowed to be curved.
What is Einstein’s theory of the universe?
Einstein’s theory, in one fell swoop, reproduced all the previous successes of Newton’s gravity, explained the intricacies of Mercury’s orbit (which Newton’s theory couldn’t), and made a new prediction for the bending of starlight, which was spectacularly confirmed during the total solar eclipse of 1919. The only problem?
How does the universe evolve with time and energy?
Best of all, they tell you how the Universe evolves with time, arbitrarily far into the future or past. matter and energy fights against the initial expansion rate. In our observed Universe, a cosmic acceleration is caused by some type of dark energy, which is hitherto unexplained.
Is the universe curved?
There’s all the matter, radiation, and any other forms of energy that make up the Universe. There’s the curvature intrinsic to space itself, dependent on whether the Universe is closed (positively curved), open (negatively curved), or flat (uncurved).
