Time and Space: What Came First?

In summary: Summary:-Spatial expansion and time increase as space does-The direction of time is defined by the Big Bang-Time is always positive, even when it points in an opposite direction

Hello all, After reading about how time began at the moment of the big bang and how time ends in black holes, if there was only 1 big bang and many black holes, would times be decreasing i.e. slowing down. Any thoughts would be appreciated , thx

It might be more accurate to say time "breaks down" in black holes, though we don't really know what happens inside a BH. Time "ending" in a BH is not really the counter-equivalent of time "beginning" at the BB.

thank you for your reply. If there is a beginning of time is there not an end of time.

Time starts in Big Bang.
Then time splits. This means world lines split.
Then world lines usually goes to infinity, but some of them ends in black holes.
There is NO the same time for ALL observers!

WEll, time might end with hte heat-death of the univerese, when the entire universe's nergy and matter are distiibutred evenly, or it might end in a "Big Crunch" - the reverse of a Big Bang.

Thank you that makes senseish stuff, I'll think about that, good night all

Time Eh?

What do you think of this [remember the forum rules, lol]?

Scenario: Big Bang, space expands, time increases.

Apparently simple but let's check it out

Spatial expansion is 3d in a 4d embedding space. This means we need to take the balloon analogy where space is the surface of an expanding balloon. NB the two dimensional surface represents the 3d space we exist in. OK so as the balloon gets bigger space increases.

Time also was created yes? How? How did it relate to the space? Is it not easy to accept that time also probably expanded from a point? Can we think of time as the radius of the balloon? As space moves outward the radius increases. At "c"?? Lol. when inflation is occurring? Yup "C"... IMHO - explain if you ever debate that far.

So anyway a radius for time direction. Note a positive direction for time has an equal opposite direction that is also positive. Apparently then time is always positive even when it points in an opposite direction! It would seem then that time is a PROCESS rather than a dimension even if it acts always at 90 degrees to the spatial directions of an observer. That is acts within an additional dimension to the 3 spatial dimensions of an observer.

However, the embedding 4d space (where any direction could be time) is modified by the BIg Bang. The BB expansion defines the direction of time for any given location within the universe. Obviously this becomes modified by rotation where speed is involved i.e. actual movement relative to any radial line from the BB origin.
 

What is the Big Bang theory?

The Big Bang theory is a scientific explanation for the beginning of the universe. It suggests that around 13.8 billion years ago, all matter and energy in the universe was compressed into an extremely small and dense point called a singularity. This singularity then expanded rapidly, creating the universe as we know it.

How do blackholes form?

Blackholes are formed from the collapse of a massive star. When a star runs out of fuel, it can no longer produce the energy needed to support its own weight. As a result, the core of the star collapses, creating a blackhole. This happens when the core is around three times the mass of our sun.

What is the event horizon of a blackhole?

The event horizon of a blackhole is the point of no return. It is the boundary around the blackhole where the gravitational pull is so strong that nothing, not even light, can escape. Once something crosses the event horizon, it is pulled into the blackhole and cannot escape.

How does time behave in a blackhole?

Time behaves differently in a blackhole compared to the rest of the universe. As you get closer to the event horizon, time slows down due to the intense gravitational pull. At the event horizon, time appears to stand still, and inside the blackhole, time moves towards the singularity. This is known as time dilation.

Can we travel through time using blackholes?

While blackholes can cause time dilation, it is not possible to use them to travel through time. The intense gravitational pull would rip apart any object that gets too close, making it impossible for anything to enter or exit a blackhole. Additionally, the extreme conditions inside a blackhole would make it impossible for any known form of life to survive.
