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.
What else can I help you with?
Why do observations made of distant galaxies indicate that dark energy exists?
The observations made from distant galaxies suggest that Dark energy exists. This is because of the fact that the galaxies are moving away from each other. This is given by Hubbles law.Instead of being attracted by the force of gravitation,galaxies tends to move away suggesting the presence of a gravity opposing force called dark energy.
Is Mars lifeless?
Evidence indicates the presence of water, which supports life as we know it.
Is the universe matter?
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.
Leaving evidence of your presence supports U.S. Government effort to locate identify and recover you.?
True
What is the opposite of Dark Energy?
There is no opposite of dark energy in the sense that there exists something that is the exact opposite of dark energy. Dark energy speeds the rate of expansion of space, even empty space, and gravity, mass, or matter causes the opposite in that it causes a decrease in the rate of expansion of space in areas that have matter.
What does the presence of dark lines in the solar spectrum mean?
The dark lines represents the absorption of energy at that frequency, E=hf.
What are the is activity of plant cells in the dark and in the sunlight?
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.

Which is thought to be more prevalent in the universe dark matter or dark energy?
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
When was Dark Energy Digital created?
Dark Energy Digital was created in 1998.
Can Astronomer's directly detect dark energy and dark matter?
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.
How would earth changes if the sun suddenly went dark?
The Sun is our main source of energy ehich supports life on earth,therefore if the disappeared,then all life on earth would end.
Can evaporation take place in the dark?
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.
What does dark energy seem to be doing?
Dark energy is the force that is driving the expansion of the universe
When it is dark does solar energy work?
Solar energy can be USED in the dark, but cannot be collected .
A gas that promotes burning?
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.
