Of course it hasn't because we haven't observed anything traveling faster than the speed of light. Expansion rate that's faster than the speed if light? That's the debate. Yep So for all we know; the universe is much larger than we are advertising?
The rubber that makes up the balloon is the visualization of space/time. Not the shape. That's why he also showed the sidewalk visualization. The thing is, he has all his things standing still. People standing on the sidewalk or painted on the balloon. For real, the things were moving in space/time as well. That's how you get things that appear to move faster than the speed of light. Speed of light + expansion gets you a distance greater than the speed of light alone would.
That was a great explanation! I got a better understanding of it now. Their was two types of momentum (expansion of space and the speed of light for physical objects)? So basically the probability of getting to galaxy z; could be as simple as finding ways to channel into the river of space?
I live by a seacliff (Cascade Head, which is an ancient volcanic island) which has 14+ exposed alternating layers of fine sedimentary deposits and basalt lava flows in increasing states of oxidation as you descend. there is no objective way to look at this and not conclude it must have taken a very long time to form (much, much longer than 6000 years). trying to explain this as something that might have formed quickly when god suspended the laws of physics is silly. you might as well go ahead and say god intentionally created the earth to deceive us into concluding it is unquestionably old. god is quite the prankster.
No no -- it's as simple as bending spacetime such that point A becomes right next to point B. A "wrinkle in time", if you will.
my understanding is inflationary theory as it is currently formulated wouldn't change how the age of the universe is calculated, since we are measuring based on what happened after inflation. who's we? if inflation is true (our big bang) universe may be many orders of magnitude larger than we can see. many astrophysicists think that is likely to be the case.
Actually no. What if the earth had high levels of oxygen to oxidize that mass? Think of it like injecting high levels of oxygen to a molten mass of iron. You know when we make steel? It has been observed that one could speed up processes just by increasing levels of temp, oxygen or hydrogen. We do this everyday.
I find it remarkable that a lot of the technology in the original star trek tv show is becoming real science. The bending of space as you showed it would destroy a lot of things - stars, planets, etc., that got crunched by the bend. But if you bent a mile of empty space at a time and moved like the ant in your picture, you'd have warp drive. It would require something like the matter/anti-matter engines they had on the ship, too. The amount of power required to bend space must be ridiculous. I always thought the transporter technology was stupid. Why not just bend space like in your picture and take one step to get to your destination? The process of scanning, remembering a huge amount of data about how matter and energy are put together to make a human, then faxing that information to the target where it's reassembled makes no sense. Now it makes more sense with the discovery of quantum entanglement. That also would give us sub-space communications. The thing is, though, quantum entanglement and disassembly/reassembly should allow you to beam anything across any distance, no?
How can you see beyond 13.7 billion light years? It's an impossibility, since light didn't originate any earlier than the universe. Yet the universe is certainly larger than 13.7B light years. What's over the horizon?
But how can we be accurate then? What if for a split second the entire universe went to the space we see happened 10,000 years ago? What I mean is if the expansion already finished; then it's light was already where we are right now; we may have seen stars from 10,000 years ago and the continuous stream followed as the earth expanded. I agree
The graphic I posted is actually from the 60's sci-fi book "A Wrinkle in Time", by Madeleine L'Engle. Characters in the book travel exactly as you describe, though the details of the method are left vague... (Dilithium crystals may have been involved.)
