From our observation it APPEARS that our universe is flat. We could be completely wrong about that but it is what the evidence supports.
not many physicists believe the universe is perfectly flat, which is not possible to verify through experiment as you would need infinite precision. Several different measurements have put the flatness within 0.1% which leads to the conclusion that the observable universe is a tiny speck of the actual universe, the curvature is thought to have been stretched by inflation
I liken our understanding of physics to be a massive model where we don't exactly know what the whole entirety looks like, we don't really know what the pieces look like even when we find them and it isn't always obvious what pieces fit together properly and where they go in the complete model.
our data will never be proven wrong, only interpretation of the fringe cases. Newtonian physics is just as valid today as it was 250 years ago, relativity simplifies to Newtonian physics at everyday scales and speeds
Take for instances, special relativity, it has worked out experimentally but for all we know, it could be our instruments giving bad readings due to the differing amount of gravity/speed (you have to remember that with the right reference frame, we are moving at extremely high speeds due to the movement of our planet and solar system). We generally accept that the speed of light in a vacuum is the maximum speed limit according to the evidence that we have but we have yet to prove that you cannot go any faster (last I heard, the fastest we have made anything go is around 97% of the speed of light).
particle accelerators routinely accelerate particles to 99.9999% of light speed. light speed is just the speed any field changes can propagate through space, it is not limited to light and that is why it is a fundamental limit.
Assuming that we don't wipe ourselves out first, one day someone somewhere will have a "oooooohhhhh, I see now" moment and put all (or at least most) of the pieces together properly. But, until then, we are going to be trying to put together and describe the model in ways which make our descendants cringe...
They may cringe but it is completely rational. Again at everyday energies and scales Newtonian physics is 99.999999% correct and always will be a very valid description of this time in our universe. Quantum mechanics and special relativity are add ons to Newtonian physics that are irrelevant to the corecorrectness and mathematical elegance it provides. Any future theory will simply be an add on to existing theory, existing theory will never be found incorrect for the energies and scales it describes.
Bats "don't really swoop down on your head and get tangled in your hair." They also don't eat 1,000 mosquitoes an hour (PDF).
To be fair pesticides can't even eat bugs.
Thanks for the info, i will now boycott all hostess products. Twinkies suck anyways lol haven't eaten one in 20 years.
Go ahead and eat one of those still left in your pantry, 1996 was a good year for twinkies.
In Canada, the BLM movement unfortunately chose to demonstrate during the pride parade in Toronto and felt justified to delay someone else's cause for 30 minutes. I think the hashtag should be #BlackLivesMatterMOST.
Agreed. You know what the sadest outcome of that movement is? Native lives matter. Pretty much any metric of your choosing, natives have had it worse than any group - including police deaths per capita. Black lives matter throws every other repressed group under the bus with a me first attitude. The result being divisiveness between groups like blacks, Hispanics, and Native Americans, among others, which ultimately makes it even easier to walk over their rights and injustices than if everyone banded together in unity.
Almost a year ago, a massive data breach put all the details of would-be cheaters out in the open. Result: lots of publicity, and an increase in membership numbers.
