Creation of the Universe - A Personal View Our universe seems to have a absolute beginning of space-time, so that means causality must extend beyond time. — Devans99
All known instances of causation entail a cause that is temporally prior to the effect. How can something that is causally efficacious exist "beyond time"? This is a key premise and is in need of support.
photons are timeless yet they change.
Photons (which are quanta of the electromagnetic field) don't change. Rather, the energy of the field ripples across space.
There must be a timeless realm in which our universe was created:
1. Something can’t come from nothing
2. So base reality must have always existed
No problem with #1, but #2 is more precisely written as: base reality exists at all times.
3. If base reality is permanent it must be timeless (to avoid an actual infinity of time)
Non sequitur. An initial state, with a potentially infinite future is not timeless.
4. Also something without a start cannot exist so time must have a start
The initial state constitutes a "start".
5. Time was created and exists within this permanent, timeless, base reality
non-sequitur.
Why think anything that is causally efficacious can exist timelessly? Abstractions (if we regard them as existing at all) exist timelessly, but they aren't causally efficacious. The universe is not "timeless" - it experiences time.
