What are the two main source of energy?
Two sources provide more than 99 percent of the power for our civilization: solar and nuclear.
Every other significant energy source is a form of one of these two.
Most are forms of solar..
What are the 10 positive emotions?

What is the most dangerous thing in the universe?
Yet if Swift-Tuttle were to strike Earth, it would release more than one billion MegaTons of energy: the energy equivalent of 20,000,000 hydrogen bombs exploding all at once. Without a doubt, the comet that gives rise to the Perseids is far and away the single most dangerous object known to humanity.
What is the main source of energy on Earth?
the sunThe energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.
Is the universe infinite?
The universe is unquestionably huge. … The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
How much positive energy is in the universe?
And the total positive energy content (excluding the gravitational potential energy) is about 5 or 6 proton rest-mass equivalents per cubic meter. (About 935 MeV per proton).
What is the source of all energy in the universe?
HydrogenHydrogen: The Most Abundant Source of Energy in the Universe – Joi Scientific.
Does energy increase in the universe?
[T]he total energy of the universe is increasing such that the energy inherent of space-time is kept constant as the universe expands. It is like, in order to build an extra cubic kilometer of space-time you need this quanta of energy. No more and no less. This energy has to come from somewhere.
What is the fastest thing in the universe?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.
What are examples of negative emotions?
Negative emotions — like sadness, anger, loneliness, jealousy, self-criticism, fear, or rejection — can be difficult, even painful at times. That’s especially true when we feel a negative emotion too often, too strongly, or we dwell on it too long. Negative emotions are impossible to avoid, though.
What is the strongest force in the universe?
strong nuclear forceThe strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.
What is the main source of energy?
Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019. Natural gas is used in steam turbines and gas turbines to generate electricity.
Can positive exist without negative?
With electricity there are positive and negative charges. Without one the other can’t work. In a world without negative charges their would be no charges period because positive charges can’t work without negative charges.
Can we create negative energy?
Positive masses attract each other, but with a negative mass, gravity could suddenly become a repulsive force. Quantum theory, however, allows negative energy. “According to quantum physics, it is possible to borrow energy from a vacuum at a certain location, like money from a bank,” says Daniel Grumiller.
What has the most energy in the universe?
Gamma-raysGamma-rays are the highest-energy form of light in the universe. Some are generated by transient events, such as solar flares and the huge star explosions known as supernovas. Others are produced by steady sources like the supermassive black holes at the hearts of galaxies.
