Just to add onto this comment, it’s thought that the Sun is slowly getting hotter and more energetic as it gets older and in approximately 1 billion years, the Sun will be hot enough to render the Earth uninhabitable for life as we know it.
In approximately 5 billion years, the Sun will reach the end of its life and expand into a red giant, swallowing up Mercury, Venus and potentially Earth in the process. Interestingly, once the Sun reaches this phase of its life, it could potentially warm up some of the outer moons enough for them to have liquid water, if they can hold onto an atmosphere of course.
Someone please correct me if I said anything wrong, I’m just a casual space nerd and not a professional astronomer.
Nah, let your dog lick it clean since they have cleaner mouths than us filthy humans. Whenever I’m done eating I just let my dog lick the plate/bowl/whatever clean and then it’s good to go back in the cupboard.
