It should be pretty obvious. You are able to look in real time at Jupiter and it’s moons. Webb looked at a single point for 12h to capture those galaxies. Hubble had to look for over 100h to take the deep field image. The human eye can’t collect light for 12h to create an image. The eye also only sees visible light so everything Webb sees is invisible to us.

Brightness falls off exponentially with distance.

If you are switching to an EV it is better for the environment. While you are losing the pollution that went into making the car and you need to make the EV it’s still greener. This is because the vast majority of an ICE car’s pollution comes from using it. Basically only hybrids are efficient enough to bother keeping.

It’s really not hard. Australia is the leader in lithium mining (not China, which is actually 3rd and a quarter of Australia). The US is starting to develop its lithium reserves along with other countries. Tech is being worked on to reduce the cost of extracting lithium from salt water. It can also be extracted from geothermal plants.

The great thing is they are just greener even on current power grids using fossil fuels. This is because ICE cars are just terrible. They set the bar extremely low. Renewables are also constantly being added as we expand our grids and not just because they are green either. They can also just be the cheaper option which makes it even easier to do.

Planet killer is one that threatens life on the planet. Earth wasn't destroyed by Mars sized impact so no asteroid is actually threatening the structure of the planet.

15km is pushing humans towards extinction but not guaranteed, billions would die. 400m would be a natural disaster that could kill millions or more, depending on where it hit.

It 100% did. Any impact on any body will move it. The greater the difference between the two objects the less change there will be.

With a planet killer asteroid it will be much larger so a DART sized craft will change its orbit much less but it will still change it. So for such an asteroid we ether need to hit it years out for that tiny change to have time to propagate or we hit it with something with more energy.

They had tried to run the test a few times but it failed. It failed for the las time because they couldn’t fully shut down the reactor due to power needs and had to push the test to the next shift when power needs were less. It wasn’t about taking the reactor offline for maintenance.

You have a basic lack of understanding. Apple does spec the cable but you are allowed to use third party ones. I have a few third party cables and all of them work. The brick is completely open. Apple has no control over what brick you use.

The new rule the EU is proposing would prohibit Apple from restricting functionality to only approved cables. They would have to work with any valid cables that adhere to the USB and Type-C spec.

Stop creating bogymen to then get angry at them. Apple already uses Type-C on Macs and iPads. They've literally shown what it would look like and people still complain about fake stuff.

You are being downvoted by idiots. You can use any USB charger with an iPhone. I use generic ones and Samsung ones as well as Apple ones. They are all just a USB port which is an open standard. You do need to use a lighting CABLE. This is a different thing than the wall connector and technically none are chargers. The charger is built into the phone.
