So in this case, you have non-unique solutions and physics requires at least probabilities of what your unique solution should be. With string theory you can throw in a bazillion different inputs and get an infinite number of outputs, it seems like. For one set of data in, you get one set of data out. Pamela: But the thing with relativity is it made a unique set of predictions based on a unique set of observables. In fact, they’re only just now starting to understand. Think about relativity: Einstein worked out the math before anyone was able to see his predictions in reality. There are a lot of different versions of string theory that all build off of one another in slightly different ways and come up with slightly different predictions and the things that they’re predicting aren’t unique to just string theory, there are other theories based on the more standard model of particle physics that make similar predictions.įraser: But we don’t want to disparage mathematical predictions, I mean many of the great discoveries of the Universe have been done in precisely that way. One of the problems with string theory is, because it’s a mathematical invention, you can tweak the parameters to get it to fit almost anything. When we look at sub-atomic particles, what we’re seeing is just one aspect of a particle that is a string if you’re able to see it in the multiple different dimensions – this is where the “string” in string theory comes from. It starts off with the premise that our Universe doesn’t exist just in the three spatial dimensions we experience, and time, but rather it has other dimensions as well. Pamela: String theory is a mathematical attempt to unify all the different forces. All right, but let’s try and cover some of these topics as much as we can to explain at least where there could be evidence. So Pamela, what is the evidence to support all those topics?įraser: None. Thanks to science fiction, comic books, there’s a lot of ideas there that do relate to space and astronomy but which don’t quite have any evidence whatsoever, and yet they’re in the popular thinking, so we get questions about them all the time. If you think about our Big Bang show early on, we provided four different lines of evidence that support our understanding of the Big Bang. One of our goals with Astronomy Cast is to present evidence that supports our current understanding of the Universe. We try to kind of put them aside or hold off, but we need to address it. Now that you’ve accessed your WarpSpeed VPN instance, checkout the official Wirespeed VPN documentation to learn how to further configure your WarpSpeed VPN instance.Fraser Cain: So here’s the problem: we get questions sent in every week about the topics in the title of the show, especially string theory. Example: įor more documentation on how to assign a domain to your Linode, please review the (/docs/guides/dns-manager/) guide for instructions on setting up your DNS records in the Cloud Manager, and read through (/docs/guides/dns-records-an-introduction/) for general information about how DNS works.įrom here, you will be able to login with the Admin Email & Admin Password you entered during the initial deployment of the Linode. Once your domain has been assigned and has finished progating, you will be able to visit the login dashboard by entering the domain in your browser. Once your WarpSpeed app has finished its installation, you will want to ensure that you have assigned the domain to your Linode. Recommended plan: All plan types and sizes can be used.Supported distributions: Ubuntu 20.04 LTS.That said, some options may be limited or recommended based on this Marketplace App: This is the directory that your WarpSpeed data will be stored in, default will be /warpspeed.įor advice on filling out the remaining options on the Create a Linode form, see Getting Started > Create a Linode. This is the domain you will be using for your WarpSpeed instance. This is the admin user password to login to your WarpSpeed instance. This is the admin user email to login to your WarpSpeed instance. Software installation should complete within 10-15 minutes after the Linode has finished provisioning. It can also be used to enable remote workers to access the internet securely while on public WiFi. WarpSpeed makes it easy for developers to access cloud infrastructure via the powerful WireGuard® VPN protocol. Low-latency and feature-rich VPN powered by WireGuard® protocol.
