Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy--or could it really be possible to travel through time or take shortcuts between stars? Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space--and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible--killing your own grandfather is only one of them Written with a light touch and an irrepressible love of the fun of sci-fi scenarios--but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.Binding Type: Paperback

High Quality and Smells Great!
This is so far superior to the standard soaps that you buy off the shelf in a supermarket. It creates a truly luxurious lather and smells fantastic without being obnoxious or perfume.

Best vanilla body wash I've seen
Proper vanilla scent with a kick, without the vomit inducing synthetic aftertaste

Natural, Gentle, and Smells Great
Style: Most Popular
I picked these up to try something more natural, and I love them. They lather well, feel gentle on the skin, and leave it feeling clean without drying it out. The scents are really nice too. They feel like good quality bars.

Longevity, scent, quality 10/10
Style: Most Popular
I’ve gone through just about the whole box and I will be buying more.
I bought these early November 2025 and now that it’s almost May of 2026 I’m down to my last two bars so id say they last awhile. I use them for body wash and will be using them for hand soap once I go through my stash of bar soaps from other brands.
It lathers nicely, with a light scent, natural not over bearing chemical scents.
I use this as body wash and hand soap.
I haven’t noticed any skin irritation, just a good ole natural soap (:
I love how there’s no plastic in sight other than maybe amazon packaging

Better than expected...
Style: For Him
I love going to a craft show or a place that sells a handcrafted soap. A good craftsperson can produce a high-quality soap that cleanses, moisturizes, and leaves a good scent. I gave these a shot after running out of those soaps.
They did beat my expectations. I thought these would be a factory produced and chemically. While you can tell these are churned out pretty regularly in some sort of factory, the overall quality is good.
Each scent is full and unique without being overpowering. They seem to be natural and not generic chemical smells. Really enjoy each of the unique scents.
The bars themselves aren't that big. They come in a piece of cardboard and are very uniform. There is some texture to the soap, as well as an added bit of something to give it some grit. I like it. This isn't lava soap but there is something (about the size of fresh ground pepped) mixed throughout each bar.
A drawback overall is how long they last. I would estimate less than a week for a daily user. I thought, given the denseness, they would last for a longer than they do. I'll probably use the entire box in under a month.
Of note is the lack of slimy or slipperiness to the soap. I like this. Some soaps that I've used in the past leave you slimy and you can barely hang on to the bar. This rinses very well and doesn't make you feel slimy.
Overall, these are a good replacement for the 'true' homemade soap. I am happy with them and would purchase them again.
