The evidence that we live in an expanding, and not a static,Universe is as solid as the evidence that we live in on a round, and not a flat,planet. Gravity is the only force we know of that could slow down "Hubble" Expansion but, for many decades, we were unable to calculate how rapidly this slow-down of Hubble Expansion was occurring. It was QUITE a shock when we found that, over time, the rate of expansion was INCREASING over time. Again, this fact is as irrefutable as the fact thatour Earth is going around our Sun.
Since we "define" dark energy as "whatever it is that is causing the rate of Hubble Expansion to increase over time," the fact that the rate is increasing is all the support that is needed.
Observations of distant galaxies show that they are moving away from us at an accelerating rate, implying the presence of a mysterious force counteracting gravity known as dark energy. This is supported by measurements of the cosmic microwave background radiation and the large-scale structure of the universe, which also confirm the existence of dark energy.
Evidence indicates the presence of water, which supports life as we know it.
True
The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.
Andesite gets its dark colour from the way its crystals stick together.
The dark lines represents the absorption of energy at that frequency, E=hf.
In the dark, plant cells undergo respiration to release energy from stored sugars. In sunlight, plant cells undergo photosynthesis to convert light energy into chemical energy in the form of sugars. They also produce oxygen as a byproduct in the presence of sunlight.

Oxygen is a gas that supports combustion by providing the necessary element for burning to occur. It is essential for fuel to burn in the presence of oxygen, which allows for the release of energy in the form of heat and light.
The Sun is our main source of energy ehich supports life on earth,therefore if the disappeared,then all life on earth would end.
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
Yes, evaporation can take place in the dark. Evaporation is a physical process in which liquid water molecules at the surface gain enough energy to escape into the air as water vapor, regardless of the presence of light.
Dark Energy Digital was created in 1998.
Dark matter and dark energy have NOT been detected yet, so any ideas about detecting dark energy and dark matter, whether it be directly or indirectly, is speculation for now.
The sun's energy, which supports life, is transmitted to Earth in the form of?
Oxygen supports burning through the process of oxidation, in which oxygen molecules react with the atoms of the burning material, releasing energy in the form of heat and light. This can be proven by conducting controlled experiments in a controlled environment where oxygen is present, and observing how materials burn in its presence compared to in its absence.
