Explanation:
answer:
How do we know that out of 100 percent, 4.96% is Matter, 0.42% is Neutrinos, approx 25% Dark matter and rest 70% is dark energy. How do we know about these percentages if we don't know how large the universe is? Or are these calculations based on the spaces of the VISIBLE universe? It does not make a difference because the universe seems to have the same composition everywhere - this has been verified within the visible universe, so theories assume it is true outside as well. Are Dark matter and Baryonic Dark Matter different to each other? Dark matter is more general, and most of it is probably not made out of baryons. Does the Flyby anomaly occur because of dark matter? Very unlikely, as we know the gravitational attraction of earth (independent of its content!) very well.
