Science can be sure the universe is expanding because science can measure the effect in more than one way, each giving verification to the findings of other.<quoted text>
Did you read all 17 verses on the website?
You are confusing matter and energy, the missing 5/6th (not 75%) of the universe is dark matter which can now be catalogued, measured and its effects photographed.
Dark matter and dark energy are two completely different things.
Of course science understands why the corona gets so hot,(they didnt up to the late 40s early 50s when a rational and mathematically provable explanation was conjectured but they do now) and have sent up satellites to verify their understanding.
No mystery, see above
Again, very old hat, science has understood the processes of a stars life for years (including the massive stars that go nova). I occasionally dine with a celebrated particle physicist who has great fun explaining how you are made from the ashes of a 2nd generation sun and will more than likely become fuel for a 4th generation sun.
Plasma and pressure, so yes we do have an idea why.
Everywhere, the universe is big, driving to the supermarket is peanuts compared to the size of the universe. In every direction stars are exploding all the time releasing energy deliberately to confuse the godbots.
Is our solar system odd? As more and more solar systems are discovered (currently at the rate of 2 or 3 a day science considers our solar system is typical. The solar system formed by accretion caused by gravity, just as all other planets, solar systems and galaxies are formed. You also have problems with the meanings of chaos and logic, the solar system formed of the logical consequence of gravity but gravity has no concept of logic, the results are chaotic, that chaos is itself caused by gravity.
I assume this is a christian trick to ask the same question over and over again, you have previously asked this, see above.
If you want to use half century old science to make a point please dont be surprised if you are shown to be out of date.
Each of these statements can be verified by searching google (or whatever) for the relevant terms. 50 year old science does your credibility not the slightest good.
