What's their theory or rather....how can time not exist?Some theorize that time doesn’t actually exist
It is a Gigawatt. There is no unit of Jiga.
Nah. Neither of those examples have the materials occupying the same space.From a related post of over two years ago;
There's this Law of physical science to effect that there is a finite amount of energy and matter in this Universe. A sum total of both and while energy could be changed into matter, or matter into energy, the sum total of both is a constant amount.
So let's say you hope into your time traveling spaceship and want to go back just 10 months into the past. And before you hoped in, you had a hamburger sandwich for lunch.
Ten months ago the wheat that became the bun of your burger was seeds on stalks growing in a field in Nebraska. The meat for the hamburger patty was still flesh of the cow grazing in pasture (or feed lot).
Once back ten months in time ...
Is that wheat still grains on the stalks or in your stomach?
Since matter can't be in two places at the same point in time, that 'wheat' is either 'grain on the stalk' or you have some holes in your stomach ~ GI track.
As for the meat patty, is it still part of the flesh of the still alive cow or in your GI track, or digested already in your blood stream/cells? It can only be one of those two places so does the cow now have some holes in it or do you have holes in you?
We could do a similar mind experiment where the aluminum used in the structure of your 'time&space travel machine', which has now gone back to this time in 1944; was part of the structure of a B-17 bomber and question is; does that B-17 bomber now have holes in it for the aluminum in your device, or does your device have the holes?
If your device has the holes, are they in critical parts that have now made your device inoperative?
"Time travel" might be a fun device for science fiction authors to toy with, but if doing realistic science, then "time travel", the "lever pulling, button pushing" sort, is just plain impossible
Nah. Neither of those examples have the materials occupying the same space.
It is possible if you can build a Flux Capacitor with 1.21 Jigawatts of power at 88 mph.

Realistically, it takes a nuclear reaction or a bolt of lightning to generate that much power

Ya but just one jigawatts can destroy an entire galaxy!Or just sit 93,000,000 miles away from a small sub-dwarf yellow star ... better than a kilowatt per square meter there ... a jigawatts isn't that much power ... you can tell, any number with a prefix is small compared to astronomical numbers ... like 6 x 10^23 is small for comparison ...

That is what Avagadro would sayOr just sit 93,000,000 miles away from a small sub-dwarf yellow star ... better than a kilowatt per square meter there ... a jigawatts isn't that much power ... you can tell, any number with a prefix is small compared to astronomical numbers ... like 6 x 10^23 is small for comparison ...
This subject fascinates me and it would be neat if we could go back in time to see relatives and close friends that have passed away.
Time travel is theoretically possible, calculations show. But that doesn't mean you could change the past.
Some theorize that time doesn’t actually exist
While the concept of time travel has captured the imagination of many, the scientific consensus is generally skeptical of its feasibility. Here are several reasons why time travel is considered practically impossible:
1. Violation of causality: Time travel often implies the ability to change the past or future. This leads to paradoxes such as the grandfather paradox, where traveling to the past and altering events could prevent one's own existence. Such paradoxes undermine the fundamental principle of cause and effect.
2. Lack of evidence: Despite extensive research in numerous scientific fields, no verifiable empirical evidence for time travel exists. The absence of any concrete evidence indicates that time travel, as commonly imagined, may not be feasible.
3. Consistency with general relativity: According to Einstein's theory of general relativity, spacetime is a four-dimensional fabric that is influenced by mass and energy. While his equations allow for theoretical solutions that permit time travel, these solutions typically require extreme conditions like negative energy densities or infinitely long cylinder structures, which are currently beyond our technological capabilities.
4. Technological challenges: Time travel would likely require vast amounts of energy and advanced technological capabilities that are currently beyond our reach. The energy required to manipulate spacetime or create wormholes would likely be astronomical, making it highly impractical to achieve.
5. Paradox resolution: Even if time travel were possible, resolving the aforementioned paradoxes would pose significant challenges. The notion of altering the past raises logical and philosophical conundrums that are difficult to reconcile, such as the question of multiple timelines or the preservation of free will.
6. Conservation of energy: Time travel could potentially violate the principle of energy conservation. Maintaining consistency within the laws of thermodynamics while manipulating time would be a formidable task, as it may require the creation of negative energy or altering the total energy of the universe.
7. Lack of evidence from the future: If time travel were possible, one might expect evidence of future inhabitants or visitors in our present time. The absence of any such evidence casts doubt on the feasibility of time travel.
While time travel remains a fascinating subject in science fiction, the aforementioned reasons suggest that it is currently considered practically impossible within the constraints of our current understanding of physics and the universe.
