Say 300-500 years from now, if we dont extinct ourselves by then, could we have the knowledge to time travel? Look at how far we've advanced in technology in the last 50 years and the rate that it is increasing...
If so, then do we have people walking around from the future right now? They'd probably be smart enough to know not to change anything...
What about aliens? Could they be our future smarter selves? Maybe our earth becomes inhabitable so the elite humans get to inhabit this new planet with new laws of gravity so their body has less mass, which is why aliens are described as skinny. The reason we cant find them is because in our time, they dont exist, but maybe in 500 years we've colonized the moon or something and learn new laws of physics which dont exist on earth which is why we dont have that technology yet.
Am I crazy?

What is the change in reaction enthalpy ( ) for the following

2 NO (g) + 2 O2 (g) + 2 N2O (g) → 2 N2O4 (g) + N2 (g) = ?

having carried out the experiments listed below
2 N2 (g)+ O2 (g)→ 2 N2O (g) = +164.1 kJ
N2 (g)+ O2 (g)→ 2 NO (g) = +180.5 kJ
N2 (g)+ 2 O2 (g)→ N2O4 (g) = +9.2 kJ

Descartes..I think therefore I am...has to be the baseline for all philosophy and/or science but subjective results are taken into account now with experiments involving quantum theory...this implies that consciousness is more than just a chemical process...please this is a proper question asked out of pure interest...thanks

The average years of employee experience at a company with 10,000 employees is normally distributed, with a standard deviation of 12 years. If a sample of 50 employees indicates a mean age of 38, calculate 90 percent and 99 percent confidence intervals for the population mean.

Think about it: Whatever you do as a human being actually HURTS the environment. If you think deep, you'll see:

For you to drink a glass of water, it was necessary to either drain an underground water reservoir or to dam a river.

For you to eat your veggies, fields had to be deforested for farmland, and herbi-and-pesti-cides had to be sprayed over crops.

For you to be born, your Mom had to be driven to a hospital, which caused the vehicle to release greenhouse gases.

For you to use the very computer you're using now, hydrocarbons had to be turned into plastics, metals had to be mined and molten, silicon had to be chemically treated and the whole machine had to be built and shipped, causing lots of pollution.

Even a walk in the park pollutes.

What do you say?

If an infinite amount of nothing equates to something as in the above equation does this demonstrate that there has to be something rather than nothing in a cosmological context?

Is it something to be worried about? Could it not be compensated with technological advancements? Tomorrow may be a machine world. Man will be many times advanced. Why should he be in need of water, trees. Rather won't they be outdated? And so why not exploitation of resources?

I was wondering if water is a conductor...and they always tell you to get out of the water when lightning is in the area....then how come the fish and the wildlife in the ocen are not affected by the lightning? Or are they? You just don't see them dying or being struck by the lightning. I was just wondering what it is or how they are not affected.
