In other words, "The Tao that can be described, is not the true Tao."

"can be described" implies by those who grew comprehension of perceived inspiration. The issue stems from suggesting this as information towards others; which tempts those to ignore perceived inspiration for suggested information. What they ignore is to grow comprehension by themselves out of perceived.

The perceived Tao cannot be unlocked by accumulating information; it offers constant inspiration to allow each one within the ability to grow comprehension of it. Each of us needs to grow self; not trying to accumulate as much suggested information about nature as possible.

The Tao offers ALL to each ONE within as perceptible inspiration at every moment; yet comprehending what one perceives requires effort; struggle; resistance; adaptation; balancing by choice...it requires temporary growth (form) within ongoing loss (flow). Me describing all of this represents adaptation to perceived inspiration for me; yet the temptation of suggested information for you.

I cannot make the choice for you to choose perceived inspiration (need) over suggested information (want). Inspiration cannot be shared; since it's ALL already offered to each ONE within. It's suggested words like "Tao" that deceives us to collectively consent to an affixed brand; label; umbrella; idol for a system that describes itself by simply moving those within.

the very idea that the Universe "began" might not be so solidly based in scientific fact.

SCI'ENCE, noun [Latin scientia, from scio, to know.] from knowledge - "to perceive". What one perceives with ones senses represents the different consequences of being moved.

A system that moves doesn't offer those within to FACT, noun [Latin factum, from facio, to make or do] anything; only to respond to being done by everything moving.

Suggested science represents scientism aka being deceived to understand (standing under) the suggested information by others; while ignoring to grow comprehension (compressed within self) perceived (science) inspiration.

Those with eyes to see (those who resist the temptation to ignore perceived for suggested) can easily spot notices of liability (sleight of hands) by the parasitic few; such as science (to know) as the contradicting umbrella for all those in ignorance of perceived (knowledge) underneath it.

The concept of the Big Bang depends on a particular understanding of the physics of light. Namely, that the speed of light is constant, and the observed Doppler effect - that light seems to redshift, or "slow down", the further its source from us is - is explained by these sources moving away - ergo, they were once far closer, down to a defined moment of beginning.

Take all the suggested information aside and question "the moment of beginning". Moment implies the ever changing moment (um) of ongoing flow; which is only perceivable by the temporary form within. Therefore; momentum implies being in-between (life) beginning (inception) and end (death).

Look at a sinus curvature...you can see the beginning and end of the temporary curvature (form); yet also the ongoing base line (flow). That's transmutation of form out of flow. Both beginning and end of one thing exist within the ongoing everything.

if light can slow down

Question the difference between you being within the source of light; while perceiving it, and the movement required to differentiate you as the perceiving from the light as the perceivable? Velocity of flow has to be constant to sustain the momentum that hosts the temporary form within. All slow/fast perception implies as choice as the center of balance (momentum).

spacetime

SPACE, noun [Latin spatium; spatior, to wander.] represent as form within flow; while time (tick; tick; tick...) represents the perceivable momentum of ongoing flow. Spacetime represents allegory for form within flow, and consenting to the word "spacetime" gives those suggesting it the power to define; redefine and contradict the meaning thereof at their will.

Everything the few suggest deceives the many from ignoring the perceived; like being form (life) within flow (inception towards death); which when comprehending implies self discernment.

the Universe might thus be considered eternal

Comprehending the eternal ONEness of ALL (energy) implies being the transient ONE within ALL.

let alone a creator

a) the suggested creator not just deceives from perceived transmutation (shaping out of all); but also suggests a choice above the free will of choice required for ONE to shape out of ALL perceived.

b) alone represents another sleight of hand by the parasitic few...alone represents allegory for being ALL(in)ONE (energy). Meanwhile; the many who ignore this are being suggested togetherness under the umbrella of "unity"; while also ignoring that unitas - "the state of being one; oneness".
