Something has always existed. According to physics, there can never be true physical nothingness—though there can be times when existence resembles nothing, such as a vacuum (the state of minimum possible energy) (Phys.org). Creating a space where there are no quantum fluctuations requires an enormous amount of energy, and there would be a remnant of that energy in that space afterwards if the fluctuations were flushed out, plus an unstable environment (1veritasium). Even on computers, deleted data is not actually tossed away, by rather written over.

...by using additional greater-than signs right next to each other...

...or with spaces between arrows.

Lists

Unordered

• Create a list by starting a line with +, -, or *
• Sub-lists are made by indenting 2 spaces:
  • Marker character change forces new list start:
    • Ac tristique libero volutpat at
    • Facilisis in pretium nisl aliquet
    • Nulla volutpat aliquam velit
• Very easy!

Ordered

1. Lorem ipsum dolor sit amet

2. Consectetur adipiscing elit

3. Integer molestie lorem at massa

4. You can use sequential numbers...

5. ...or keep all the numbers as 1.

Start numbering with offset:

57. foo
58. bar
