Man Travels Through Time

That argument should have been dispelled about 11th grade. Matter cna be destroyed and the equation E=mc^2 is the formula used to calculate the amount of energy produced from the total destruction of a given mass of "matter"




Matter cannot exist in the same place, at the same time, and in the same quantum state. If they are in different states they can happily exist in the same place.

This is a fun distraction, thanks first and foremost.

Slight disagreement with your statement. If energy is produced matter isn't being destroyed just converted from a stable form to a higher energetic form. At least the way I have understood it. If matter is completely destroyed there would be no heat, light, particles or such produced.

Ditto, but it was my occupation for 4yrs in college (BS - Physics)

Incorrect. For matter to change from one state to a higher state, energy must be added. If energy is liberated, matter must fall to a lower state. Neverless, when matter is destroyed it is converted into energy.

Incorrect. For matter to change from one state to a higher state, energy must be added (and vice versa). When matter is destroyed it is converted into energy.

This is new info for me. The problem I see is that either E=mc^2 is missing something or energy is not added.

For energy to be added for the conversion, the equation should read:

E=mc^2 + e

where e is the added energy to destroy the matter. Typically the relativistic equations are dumbed down for us laymen and this could be the result; an ignorance of the actually equation forms.

BTW, is this off topic or was there an actual purpose to this thread that I may have forgotten?? :cross:

where e is the added energy to destroy the matter.

That equation only concerns the energy liberated as a result of the destruction. Assuming there was any energy input, the equation becomes

E + e =mc^2 + e which can be resolved to

E =mc^2 + e - e <or> E =mc^2

Typically the relativistic equations are dumbed down for us laymen and this could be the result; an ignorance of the actually equation forms.

The problem arises because HS chem teachers that matter is not destroyed (chemically, this is correct) to teach their concepts. Next year in physics, they teach that matter can be destroyed, and it is *energy* that cannot be destroyed. Most people never take physics...

E + e =mc^2 + e which can be resolved to

E =mc^2 + e - e <or> E =mc^2

Well, that's easy for YOU to say!

If you read David Deutch's theory on the multiverse and time travel, he has come up with an idea of how it is achievable within the laws of physics.

TIme travel is theoretically possible as time can be manipulated, mankind just doesn't have the skills/ resources to build machines to do it.



But if you want to time travel for short distances you just need:
3 advil,
2 Rx sleeping pills
12 beers, give or take
a cushion of some kind
Gatorade
cell phone
comfortable clothing


Step one:
Drink 5 or 6 beers
take one sleeping pill
Drink 5 or 6 more beers
Stand in front of the cushion with your feet together, tilt your head back, close your eyes and try to touch your nose....

Find yourself 10-12 hours in the future

TIme travel is hard on the body and will give you some aches, that's what the advil and gatorade are for. The cell phone is in case you need to call for a pizza.

yup, him and his dad got tats together.
