Matt Dillahunty vs Sye Ten Bruggencate

[brewer]

I don't have time for xtian/atheist debates.

Actually I do have the time but I find them tedious and won't take the time.

It can be fun to debate but don’t expect to change anyone’s mind. It doesn’t matter if what you say is logical or if it is documented.

Once, I told someone that the Big Bang theory doesn’t state that the universe came from nothing. I gave him some links to check. He accepted it.
Other than that, I never changed anyone’s mind, not even on an iota of information.

Discussion on science are interesting.
I was talking to a flat Earther.
There is something about the very high temperature of a far out layer, around the Earth. The temperature is around 6000 °C.
His objections are:
1. The space shuttle is made of aluminium, which has a melting point of 660 °C and satellites are also made of aluminium.

Answer:
Energy density and energy exchange.
Here on Earth, if I have a block of iron at 20 °C in a room with the air at 20 °C. The energy exchange between the iron and air is equal. Both objects will remain at 20 °C.

In space, you can have some gas or plasma at 6000 °C but if number of molecules per cm3 is very low, then they don’t give much energy to your aluminium.
The aluminium will absorb the energy from the plasma and will quickly radiate away as infra-red, into space.

Another example:
The neon gas in the neon signs used at stores is from 2000 to 3000 °C.
The glass tubing has a softening point of 600 °C.
If you touch the tube, you can feel a little warmth. I think it is around 40 °C.

He then said, if that were true, then how would they know the temperature is 6000 °C? The thermometer would also show 40 °C or whatever.

Answer:
That is correct. They don’t use a mercury thermometer or thermocouple. These would give false readings.
There is another device that is used that measures the speed of the atoms.


The flat earther was having trouble understanding.
